operating parameters. In programming mode it can also be used

together with the UP key for modifying the level of programming of

the parameters.

2 - UP/F1 key: used for increasing the values to be set and for

selecting the parameters.

It can also be programmed using the “Fbu” par. for performing other

functions such as manual defrosting, starting the work cycle, air-

exchange control, device power-on and stand-by etc.

Used in conjunction with the Down key, it allows the keypad to be

locked.

selecting the parameters. Furthermore, like the UP/F1 key, it can be

programmed by means of the “Fbd” par. for performing other

functions such as manual defrosting, starting the work cycle, air-

exchange command, device power-on and stand-by etc. Used in

conjunction with the Up key, it allows the keypad to be locked.

4 - U key: used for displaying all the variables measured by the

sensors (Pr1, Pr2, Pr3, and Pr4), and for manually exiting from

programming mode. Furthermore, like the UP/F1 and DOWN/F2

keys, it can be programmed by means of the “USrb” par. for

performing other functions such as manual defrosting, starting the

work cycle, air-exchange control, device power-on and stand-by etc.

In programming mode, it can be used in conjunction with the P key

for modifying the level of programming of the parameters.

5 - HEAT LED (Heating): indicates the status of the heating output

as either on, off, or blocked (flashing)

6 - COOL LED (Cooling): indicates the status of the cooling output

(compressor or other device) as either on, off, or blocked (flashing)

7 - HUM. LED (Humidification): indicates the status of the

humidification output as either on, off, or blocked (flashing)

8 - DE-HUM. LED (Dehumidification): indicates a dehumidification

procedure is in progress (on), not in progress, (off) or is blocked

(flashing)

9 - ALARM LED: indicates the status of the alarm as either on (on),

off (off) and silenced or memorized (flashing)

10 - SET LED: in programming mode, it indicates the level of

programming of the parameters. It is also used for indicating Stand-

by status.

2 - PROGRAMMING

2.1 - RAPID SETTING OF THE SET POINTS

Press and release the P key and the display will indicate “SP t”

(temperature Set point) and the value set.

To modify this value, use the UP key to increase the value or the

DOWN key to decrease it.

The keys function digit-by-digit when pressed once, but if kept

pressed for more than one second, the value increases or

decreases rapidly and, after two seconds in the same state, the

speed increases again to allow the desired value to be selected

quickly.

The "SP t” Set point can be set with a value comprised between the

value programmed in the “SPLt” par. and the value programmed in

the “SPHt” par., or it may be set as OFF (temperature regulator

disabled).

If, during the “SP t” setting mode, the P key is pressed and released

again, the value set will be memorized and the display will then

move on to read “SP h” (humidity Set point) and the value set for it.

To modify this value, use the UP and DOWN keys.

The "SP h” Set point can be set with a value comprised between

the value programmed in the “SPLh” par. and the value

programmed in “SPHh” par., or it may be set as OFF (humidity

regulator disabled).

Once the desired value has also been set for “SP h”, pressing the P

key exits from the rapid setting mode of the Set Points.

Hence, exiting from the rapid setting mode of the Sets occurs upon

pressing the P key after the display of the final Set, or it is exited

automatically in the event that no keys are pressed for

approximately 15 seconds, after which the display will return to

normal operating mode.

Note: if there is a work cycle active, the rapid setting mode will

sequentially show the active temperature Set Point (SPt1, 2, 3), the

active humidity Set point (SPh1, 2, 3), and the time remaining in the

phase in progress (tr 1, 2, 3). These values can be edited in the

same way as the Set points.

2.2 - STANDARD PROGRAMMING OF THE PARAMETERS

To gain access to the operating parameters of the appliance when

the parameter protection is not active, press and hold the Pkey for

approximately 5 seconds and the display will show the code that

identifies the first group of parameters (“

]

SP“). Use the UP and

DOWN keys to select the group of parameters that contains the

parameter it is wished to edit.

Once the desired group has been selected, press the P key and the

display will show the code that identifies the first parameter of the

group.

Again, use the UP and DOWN keys to select the desired parameter

and, when the P key is pressed, the display will show the code of

the parameter and its setting, which can be modified by means of

the UP or DOWN keys.

Once the desired value has been set, press the P key again: the

new value will be memorized and the display will again show only

the code of the parameter selected.

Using the UP or DOWN keys, it is then possible to select another

parameter of the group and modify it as described.

To go back and select another group of parameters, press the U

key for 1 sec. and the display will go back to showing the code of

the group of parameters selected.

At this stage, using the UP and DOWN keys, it will be possible to

select another group of parameters (if there is one).

At this point, if it is wished to exit from the parameter programming

mode, press and hold the U key for 1 sec.

If no keys are pressed for approximately 30 sec., the appliance will

automatically go to the level above until it exits from the

programming mode.

5 sec.

Hold for

1 sec.

Hold for

1 sec.

2.3 - RAPID PROTECTION OF THE PARAMETERS BY MEANS

OF PASSWORD

The appliance is fitted with a function for protecting the parameters

by means of a password that can be customized through the

“PASS” par..

In the event it is wished to implement this protection, set the desired

password number in the “PASS” parameter and exit from the

parameter programming mode.

In order to gain access to the parameters when the protection is

active, press and hold the P key for around 5 seconds, after which

the display will show the request for the user to enter the password,

reading “r.PAS”.

Ascon Tecnologic Srl - X33H – OPERATING INSTRUCTIONS – MX33HENG00 - PAGE 3

At this point, using the UP and DOWN keys, set the password

number programmed and press the P key.

5 s e c .

1 s e c .

H o ld fo r

If the password is correct, the display will show the code that

identifies the first group of parameters and it will be possible to

program the parameters of the appliance in the same way as

described in the previous paragraph.

Password protection is disabled by setting the “PASS” par. to OFF.

2.4 - PROGRAMMING OF THE CUSTOMIZED PARAMETERS

AND THE LEVELS OF PARAMETER PROGRAMMING

From the factory settings of the device, the protection by means of

password acts on all the parameters.

If, after having enabled the Password by means of the “PASS”

parameter, it is wished to make some parameters programmable

without protection while maintaining protection on the others, follow

the procedure below.

Go to programming by entering the Password and select the

parameter it is wished to make programmable without password

protection.

Once the parameter has been selected, if the SET LED is flashing,

it means that the parameter can only be programmed by means of a

password and is hence “protected”.

To modify the visibility of the parameter, press the P key and,

keeping it pressed, press the UP key at the same time.

The SET LED will change its state to indicate the new level of

accessibility of the parameter (on = not protected; flashing =

protected by means of password).

In the event the Password is enabled, and in the case that certain

parameters are “unprotected” when the user accesses the

programming mode, all the parameters configured as “not

protected” will be displayed without any division into groups, with

the “r.PAS” par. listed last, by means of which it will be possible to

access the “protected” parameters.

Hold for

5 sec .

Hold for

1 se c.

NOTE: in the event of losing the password, remove the power

supply from the device, press the P key and reconnect the device to

the power while keeping the key pressed for approximately 5 sec.

In this way, access is gained to all the parameters and it will hence

be possible to check and modify the “PASS” parameter.

2.5 - CONFIGURATION OF THE PARAMETERS WITH “A01”

The appliance is equipped with a connector that allows the transfer

of the operating parameters to and from the appliance through a

A01 device, which is fitted with a 5-pole connector.

The A01 device can be used for the serial programming of

appliances that must have the same configuration of the

parameters, or for keeping a copy of the programming of one

appliance which can be transferred rapidly to another.

The same device allows connection via the USB port to a PC with

which, using the appropriate software for configuring devices,

“ASCON TECNOLOGIC UniversalConf”, it is possible to configure

the operating parameters.

To use the A01 device, it is possible to supply power to just the

device or just the appliance.

12 VDC AC SUPPLY

For further information, refer to the user manual of the A01 device.

2.6 - KEYPAD LOCK

The keypad of the appliance may be completely locked.

This function is useful when the controller is exposed to the public

or, in any case, it is wished to block any command.

To activate the keypad lock, press and hold the UP and DOWN

keys at the same time for 5 sec. when the controller is switched on.

After the 5 sec. have elapsed, the display will read “LOn” and all

the functions of the keys will result as being blocked, with the

exception of the display of the Set Point.

If any key is pressed when the keypad is locked, the “LOn”

message is shown again to indicate it is locked.

To unlock the keypad, simply press and hold the UP and DOWN

keys at the same time for 5 sec., after which the display will read

“LOF” and all the functions of the keys will result as being

operational again.

3 - WARNINGS FOR INSTALLATION AND USE

3.1 - PERMITTED USE

The appliance was designed as measuring and

regulating apparatus in conformity with the

EN60730-1 standard for operation at an altitude of

up to 2000 m. The use of the appliance in

applications that are not expressly envisaged by

the aforementioned standard necessitates all

adequate means of protection. The appliance MAY NOT be used in

environments with hazardous atmospheres (inflammable or

explosive) without suitable protection. Note that the installer must

ensure that the regulations relating to electromagnetic compatibility

are observed, also after installing the appliance, if necessary using

special filters. In the event that a fault or malfunction of the device

should create hazardous or damaging situations for persons,

property or animals, note that the system must be fitted with

additional electromechanical devices designed to guarantee safety.

3.2 - MECHANICAL INSTALLATION

The appliance is housed in a container measuring 78 x 35 mm, and

is designed for built-in mounting flush with a panel within a casing.

Ascon Tecnologic Srl - X33H – OPERATING INSTRUCTIONS – MX33HENG00 - PAGE 4

Make a cavity measuring 71 x 29 mm and insert the appliance into

it, holding it in place with the special bracket provided. It is advised

that the special gasket is fitted, so as to obtain the degree of frontal

protection declared. Avoid positioning the internal part of the

appliance in places subject to levels of humidity or dirt that could

cause condensation or allow conductive objects or substances to

enter the appliance. Ensure that the appliance has adequate

ventilation and avoid installation in housings where there are

devices located that could cause the appliance to function outside

the declared temperature limits. Install the appliance as far away as

possible from sources that could generate electromagnetic

interference such as engines, solenoids, relay switches,

electrovalves etc.

3.3 - ELECTRICAL CONNECTIONS

Make the connections attaching only one conductor to each clamp

and following the wiring diagram supplied, checking that the power

supply voltage is the same as that indicated on the appliance, and

that the absorption of the actuators connected to the appliance does

not exceed the maximum current allowed. Given that it is designed

to be permanently connected within an apparatus, the appliance

does not have a power switch, nor is it fitted with internal power

surge protection. The manufacturer hence advises the installation of

a surge protection device and a double-pole switch/disconnector,

labelled as a disconnection device, which interrupts the power

supply of the apparatus. This switch must be positioned as close as

possible to the appliance in a place that is easily accessed by the

user. In addition, it is recommended that the power supply of all the

circuits connected to the appliance with devices (e.g. fuses) be

adequately protected from surrounding currents. Use wires with

insulation appropriate for the voltages, the temperatures and the

working conditions, and ensure that the wires connected to the input

sensors are kept away from power supply cables and other live

wires to avoid electromagnetic interference.

If some of the cables used in the wiring are shielded, it is advised

that they be earthed on one side only. For the version of the

appliance with 12 V power supply, the use of the special TCTR

transformer is recommended, or of a transformer with equivalent

specifications, and it is advised that a separate transformer be used

for each apparatus, as there is no insulation between the power

supply and the input. Finally, the user is advised to check that the

parameters set are the desired ones, and that the application

functions correctly before connecting the outputs to the actuators,

so as to avoid anomalies in the system that could cause damage to

persons, property or animals.

4 - OPERATION

4.1 - ON / STAND-BY FUNCTION

Once connected to the power supply, the appliance can be in one of

2 different states:

- ON: means that the controller actuates the control functions.

- STAND-BY: means that the controller does not actuate any

function, and the display is switched off except for the SET LED.

In the event of loss of power and its subsequent reinstatement, the

system always returns to the state it was in before the power was

cut.

The ON/Stand-by command may be selected:

by pressing the U key for approximately 1 sec. if "USrb" = 4,

by pressing the UP key for approximately 1 sec. if "Fbu" = 4,

by pressing the DOWN key for approximately 1 sec. if "Fbd" = 4,

- through one of the digital inputs if the related “diF” par. = 10

(See also the par. relating to the operation of the keys and the

digital inputs)

4.2 - CONFIGURATION OF THE INPUTS, MEASUREMENT AND

DISPLAY

All the parameters regarding measurement are contained in the

“

]

InP” group.

Using the “SEnt” par., it is possible to select the type of

temperature sensor (Pr1, Pr2, Pr3) it is wished to use, which can

be: PTC KTY81-121 (Ptc) or NTC 103AT-2 (ntc) thermistors.

Having selected the type of temperature sensor used, the “Unit”

parameter can be used to select the unit of measurement of the

temperature (°C or °F)

Similarly, with the “SEnh” parameter, it is possible to select the

type of input (Pr4) on the basis of the humidity transducer it is

intended to use, which can have a 0..20 mA (0.20) or 4..20mA

(4.20) output.

As regards measuring humidity, it will be possible to set the "SSCh"

parameter with the value that the appliance must measure in

correspondence with the start of the scale (0/4 mA), and the

"FSCh" parameter with the value that the appliance must measure

in correspondence with the end of the scale (20 mA).

Using the “dP t” parameter, it is possible to establish the resolution

of the desired temperature (OFF=1°; On=0.1°), and likewise with

the “dP h” par., that of the humidity (OFF=1%; On=0.1%).

The appliance allows the calibration of the measurements, which

can be used for recalibrating the inputs according to the

requirements of the application, using the “OFS” par. (1,2,3,4).

Using the “FiLt” par. (for the temperature measurements) and the

“FiLh” par. (for the humidity measurement), it is possible to set the

time constant of the software filter relating to the measurement of

the values at the input so as to reduce the sensitivity to

disturbances in the measurement (increasing the time).

Using the “diSU” par. (for the upper display) and the “diSL” par.

(for the lower display), it is possible to establish the normal

messages of the display, which can show: the measurement of the

desired sensor (Pr1, Pr2, Pr3, Pr4), the active temperature set point

(SPt), the active humidity set point (SPh), or it is possible to have

the numerical display switched off (OFF).

Independently of how the “diSU and “diSL” parameters are set, it is

possible to display all the variables measured in turn by pressing

and releasing the Ukey: the display will show the code that

identifies the variable (Pr 1, Pr 2 etc.) and its value.

This display mode is exited automatically after approximately 15

seconds if the U key is not pressed again.

Using the “Pr 2”, “Pr 3” and “Pr 4” parameters, it is possible to

enable (On) or disable (OFF) the measurement inputs whenever the

sensors are not connected.

In relation to the Pr2 and Pr3 inputs, by setting the related

parameters = diG, it is also possible to use these inputs as digital

inputs whose function will be defined by the “diF2” and “diF3”

parameters present in the “

]

din” group (see digital input par.).

Lastly, the user is reminded that the display relating to the Pr1

sensor can also be modified using the display lock function while

defrosting by means of the “dLo” par.

Ascon Tecnologic Srl - X33H – OPERATING INSTRUCTIONS – MX33HENG00 - PAGE 5

4.3 - CONFIGURATION OF THE OUTPUTS

The outputs of the appliance can be configured in the group of

“

]

Out” parameters, which contains the related “Out1”, “Out2”,

“Out3”, and “Out4” parameters, as well as the “buF” par., which

allows the configuration of the internal buzzer (if fitted).

The outputs can be configured for the following operations:

= CooL - for controlling the Cooling device (compressor or other)

= HEAt - for controlling the Heating

= rh - for controlling the humidification

= drh - for controlling the dehumidification

= dEF - for controlling the defrosting

= FAnr - for controlling the air recycling fans (or in any case devices

used for favouring the exchange of heat and humidity between the

actuators and the environment)

= FAnE - for controlling the air exchange / extraction fans (or in any

case devices such as dampers used for favouring the exchange of

air within the controlled environment)

= drhE - for controlling the dehumidification device and the air

exchange / extraction fans (functions like drh and FAnE in or).

= LIGH - for controlling the light

= AuS - for controlling an auxiliary device

= ALt - for controlling a silenceable alarm device through a contact

that is normally open and closed when alarmed.

= AL - for controlling a non-silenceable alarm device through a

contact that is normally open and closed when alarmed.

= ALL - for controlling an alarm device with a memory function

through a contact that is normally open and closed when alarmed.

= - ALt - for controlling a silenceable alarm device through a contact

that is normally closed and open when alarmed.

= - AL - for controlling a non-silenceable alarm device through a

contact that is normally closed and open when alarmed.

= - ALL - for controlling an alarm device with a memory function

through a contact that is normally closed and open when alarmed

= On - Output active when the appliance is in the On state. In this

mode, the output can be used for controlling the anti-condensation

resistance on the door of the cell, or for controlling lights or other

devices that require a power supply when the appliance is in

function.

= End - Output active at the end of a work cycle for the time

programmed in the “btEd” par.. This mode can be used to activate

external signalling (optical or acoustic) indicating the end of the

cycle, or to activate external automatisms (for example, product

discharge automatisms).

= OFF - Output disabled

The “buF” par. allows the buzzer to be enabled (= YES) or disabled

(=no).

4.4 - TEMPERATURE REGULATOR

All the parameters regarding the regulation of the temperature are

contained in the “

]

rEG” group.

The regulation mode of the appliance is double-action ON/OFF-type

(also known as neutral zone) and it acts on the outputs configured

as “CooL” and “HEAt” on the basis of the measurements of the

Pr1 sensor, the active temperature Set Point “SP t” and the

intervention differential “HStt”.

Remember that the operation of the temperature regulator can be

conditioned by certain timing functions (protection devices for

compressor, defrosting etc.), and by some priority criteria (relating

to the control of dehumidification) described below.

4.5 - HUMIDITY REGULATOR

All the parameters regarding the regulation of the humidity are

contained in the “

]

rEG” group.

The regulation mode of the appliance is double-action ON/OFF-type

(also known as neutral zone) and it acts on the outputs configured

as “rh” (humidification) and “drh”, “CooL” and “HEAt” (for

dehumidification depending on the setting of the “dhCn” par.) on the

basis of the measurements of the Pr4 sensor, the active humidity

Set Point “SP h” and the intervention differential “HSth”.

Whereas the control of humidification occurs only through the

output configured as rh, the control of dehumidification can be

achieved in different ways, which can be established using the

“dhCn” par. as:

= drh - dehumidification occurs through the activation of the output

configured as drh.

If dehumidification action is not required, set “dhCn” = OFF.

Remember that the operation of the humidity regulator can be

influenced by certain timing functions (protection devices for

compressor, defrosting etc.), and by some priority criteria (relating

to the control of temperature) described below.

4.6 - RELATIONSHIPS BETWEEN CONTROL OF

TEMPERATURE AND DEHUMIDIFICATION

If the appliance is configured to operate a dehumidification control

that also involves the temperature actuators (“dhCn”= drhC or HC),

and there is a simultaneous request for heating/cooling and for

dehumidification, the regulator will behave as follows:

Ascon Tecnologic Srl - X33H – OPERATING INSTRUCTIONS – MX33HENG00 - PAGE 6

- if “dhCn”= drhC, the cooling action takes priority over

dehumidification (in practice, if at the same time there is a request

for cooling and one for dehumidification, only the CooL output is

activated, and when the active temperature Set is reached, the drh

output is also activated)

- if dhCn= HC, the cooling action takes priority over dehumidification

and the dehumidification action takes priority over heating (in

practice, if at the same time there is a request for cooling and one

for dehumidification, only the CooL output is activated, and when

the active temperature Set is reached, the HEAt output is also

activated).

- If, however, there is a request for heating and at the same time a

request for dehumidification, the HEAt and CooL outputs are

activated and when the active humidity Set is reached, only the

HEAt output remains activated.

4.7 - COMPRESSOR PROTECTION AND OUTPUT DELAY

FUNCTIONS

All the parameters regarding the compressor protection function

and the activation delays of the outputs are contained in the “

]

PrC”

group.

The compressor protection function carried out by the apparatus is

aimed at avoiding frequent interventions of any compressor

commanded by the appliance through the CooL output, and it

consists of 4 time checks operating simultaneously.

The first check envisages a delay in the activation of the CooL

output on the basis of that which is set in the “PtC1” parameter

(delay upon switching on).

Lastly, the fourth check, by means of the “LCt” parameter, allows

the establishment of the minimum time of activation of the output, if

necessary delaying its deactivation, so as to avoid operating

periods of the compressor that are too short.

Similar activation delay checks are envisaged for the control of

heating HEAt (“PtH” par.), for the control of humidification rh

(“Pthu” par.), and for the control of dehumidification drh/CooL/HEAt

(“Ptdh” par.).

During all the override phases caused by the protection devices, the

LED related to the action delayed is flashing.

It is also possible to prevent the activation of all the outputs after the

appliance is switched on for the time set in the “od” par..

During the phase of delay upon switching on, the display will show

the indication od alternating with the normal programmed

messages.

The delay functions are deactivated when the related parameters

are programmed = OFF.

4.8 - DEFROST CONTROLLER

All the parameters regarding the control of defrosting, which acts on

the outputs configured as “CooL” and “dEF”, are contained in the

“

]

dEF” group.

The type of defrosting that the appliance is to carry out is

established by the “dtyP” par., which can be programmed:

= EL - WITH ELECTRIC HEATING or BY COMPRESSOR

STOPPAGE. In this mode, during defrosting the “CooL” output is

deactivated while the “dEF” output (if configured) is activated.

= in - WITH HOT GAS or CYCLE INVERSION. In this mode, during

defrosting the “CooL” and “dEF” outputs are activated.

The automatic execution of defrosting cycles occurs in accordance

with the interval programmed in the “dint” par., which establishes

the time that must elapse between two successive automatic

defrosting cycles.

Manual execution of defrosting cycles, on the other hand, can occur

using one of the 3 keys (U, UP/F1, DOWN/F2), if programmed = 3,

or by means of one of the 3 digital inputs, if programmed = 8 (see

OPERATION OF KEYS and DIGITAL INPUTS).

To start a manual defrosting cycle using the keypad, press the key

programmed for the defrosting function when not in programming

mode, and keep it pressed for approximately 5 seconds, after

which, if the necessary conditions are in place, the appliance will

carry out a defrosting cycle.

Inversely, pressing the key while defrosting is in progress

terminates the defrosting cycle.

Using one of the 3 digital inputs, if programmed = 9, it is similarly

possible to terminate a defrosting cycle in progress or to prevent

defrosting cycles.

The method of counting the defrosting cycle interval is established

by the "dCt" par., which can be programmed as follows:

= rt - interval counted as total operating time (appliance on)

= ct - interval counted as compressor operating time (CooL output

on).

The duration of the defrosting cycle can be determined by the time

or, if the evaporator sensor (Pr2) is used, when a set temperature is

reached.

If the evaporator sensor is not used, the duration of the cycle is

established by the “dEFE” par..

If the evaporator sensor is used, defrosting ceases when the

temperature measured by the Pr2 sensor exceeds the temperature

set in the “tEdF” par..

If this temperature is not reached within the time set in the “dEFE”

par., the defrosting is in any case interrupted.

For the purpose of avoiding unnecessary defrosting cycles, the

“tSdF” par. is used for setting the temperature for enabling

defrosting.

If the temperature measured by the evaporator sensor is higher

than that set in the “tSdF” par., or than that set in the "tEdF" par.,

defrosting cycles are blocked.

Defrosting cycles are also blocked whenever the temperature Set

Point is programmed = OFF.

Examples: defrosting cycle 1 terminates when the “tEdF”

temperature is reached, defrosting cycle 2 terminates when the

“dEFE” time elapses without the “tEdF” temperature being reached,

and defrosting cycle 3 does not start because the temperature is

higher than “tSdF”.

At the end of the defrosting cycle, it is possible to delay the re-

starting of the compressor (“CooL” output) by the time set in the

“tdCO” par. so as to allow the evaporator to drip.

If it is wished to execute a defrosting cycle every time the appliance

is switched on (assuming the conditions established by the “tSdF”

and "tEFE" parameters are in place), it is possible to do so by

programming the “SdEF” par. = yES.

This makes it possible to keep the evaporator always defrosted,

even when frequent power cuts occur that could cause the

cancellation of various defrosting cycles.

Defrosting in progress is signalled by the writing dEF on the upper

display alternated with the variable established in the “diSU” par..

During defrosting, it may happen that the temperature measured by

the cell sensor (Pr1) increases excessively (this obviously depends

on the positioning of the Pr1 sensor in relation to the evaporator).

If it is wished that the appliance does not display this increase, it is

possible to use the functions provided by the “dLo” par. (display

locked in defrosting) and the “Etdu” par. (display unlock after

defrosting differential).

The “dLo” parameter = On allows the display of the Pr1 temperature

to be blocked on its last reading during a complete defrosting cycle

and until, after the defrosting has finished, the temperature has

returned below the value [”SP t” + “Etdu”] (or the time set in the

"dALd" par. contained in the “

]

AL” lock has elapsed).

Or, with “dLo” = Lb, it allows the display only of the writing dEF

during defrosting and, after the defrosting has finished, of the

message PdEF until the Pr1 temperature has returned below the

value [”SP t” + “Etdu”] (or the time set in the "dALd" par. contained

in the “

]

AL” lock has elapsed).

Differently, with “dLo” = OFF during defrosting, the appliance will

continue to display the temperature measured by the Pr1 sensor.

In the event that the display is locked and a temperature Set SPt is

set = OFF, the display is immediately unlocked.

Note that during the defrosting cycles, the temperature alarms are

disabled during the entire cycle and also afterwards for the time set

in the “dALd” par..

During the defrosting cycles, the temperature regulation is always

disabled while the regulation of the humidity is established by the

“dFh” par. (=On remains active; = OFF= is disabled).

4.9 - RECYCLING FAN CONTROL

All the parameters regarding the control of the recycling fans (or in

any case of devices used to favour the exchange of heat and

humidity between the actuators and the environment) are contained

in the “

]

FAn” group.

The control of the recycling fans operates on the output configured

as FAnr on the basis of certain control states of the appliance and

of some parameters.

The “FLOF” parameter allows the user to establish whether the

fans must always be on during the regulation operation,

independently of the state of the HEAt, CooL, rh, and drh actuators

(“FLOF”=On), or whether they should switch off when all the

actuators are switched off (“FLOF”=OFF).

The “FdF” parameter allows the user to establish whether the

recycling fans must be switched on (“FdF”=On) or whether they

should switch off during defrosting (“FdF”=OFF).

In this last case it is possible to delay the re-starting of the fans

even after the end of defrosting by the time set in the “Fd” par..

4.10 - AIR EXCHANGE FAN CONTROL

All the parameters regarding the control of the air exchange fans (or

extraction fans) are contained in the “

]

FAn” group.

The control of the air exchange fans operates automatically and/or

manually on the output configured as FAnE or drhE.

Automatic mode is established through the “Frin” (interval) and

“Fron” (duration) parameters.

At the end of the interval programmed, and counted as the start up

time of the appliance, the output configured as FAnE or drhE is

activated for the time “Fron”.

Programming “Frin” = OFF means the air exchange cycles can only

be manual.

A manual air exchange cycle command can occur by means of one

of the 3 keys (U, UP/F1, DOWN/F2), or by means of one of the 3

digital inputs if suitably programmed (see OPERATION OF KEYS

and DIGITAL INPUTS).

To start a manual air exchange cycle using the keypad, press the

key programmed for the air exchange function (= 5) when not in

programming mode, and keep it pressed for approximately 5

seconds, after which, if the necessary conditions are in place, the

appliance will perform the cycle by activating the FanE or drhE

output for the time “Fron”.

If the “Fron” par. is set =OFF, the duration of the cycle is infinite and

hence it may only be stopped manually.

By keeping the programmed key pressed for 5 seconds, it is also

possible to manually interrupt the cycle in progress, whether it has

been started manually or automatically (the stop command will then

trigger the restart of the counting of the “Frin” interval).

Similar start/stop operations of the cycle can be carried out by

means of the digital inputs suitably programmed = 11. The air

exchange cycle in progress is signalled by the writing FanE on the

upper display alternating with the variable established in the “diSU”

par..

4.11 - CELL LIGHT CONTROL

The cell light command operates on the output configured as LIGH

through one of the keys or one of the digital inputs when it has been

opportunely configured.

The light is activated by means of one of the 3 digital inputs

configured = 5, 6, 7, or by one of the 3 keys (U, UP/F1, DOWN/F2)

configured = 1 (see OPERATION OF KEYS and DIGITAL INPUTS).

The LIGH output can always be activated, even when the controller

is in the OFF (stand-by) state.

If the LIGHT output has already been activated using a key, the

state of the digital input has no effect (the output must be switched

off using the key).

4.12 - AUXILIARY OUTPUT CONTROL

All the parameters regarding the functions of the auxiliary output are

contained in the “

]

AuS” group.

The auxiliary output can be configured to operate on any one of the

outputs by programming the parameter related to the desired output

= AuS.

The function carried out is defined by means of the “FOA” par. and

the operation is conditioned by the time set in the “tuA” par..

The “FOA” parameter can be configured for the following

operations:

= 0 - Auxiliary output not active

= 1 - CooL output delayed: the auxiliary output is activated with a

delay that can be set in the "tuA" parameter with respect to the

output configured as CooL. The output will then be switched off at

the same time as the CooL output is deactivated. This operating

mode can be used for commanding a second compressor or in any

case other utilities operating according to the same conditions as

the CooL output, but which must be delayed with respect to the

switching on of the compressor to avoid excessive current

absorption.

Ascon Tecnologic Srl - X33H – OPERATING INSTRUCTIONS – MX33HENG00 - PAGE 8

= 2 - Activation by front key (U, UP/F1, DOWN/F2) or by digital

input: the output is activated through the action of a front key

suitably configured for the function (= 2), or by means of the

activation of a digital input, always on condition it is correctly

configured (=12). These commands have bistable operation, which

means, for example, that upon the first action of the key or the

digital input, the output is activated, while upon the second, it is

deactivated. In this mode, the AUS output can also be switched off

automatically after a certain time, which can be set in the "tuA"

parameter. With "tuA" = OFF, the output is activated and

deactivated only manually; inversely, once it has been activated, the

output is switched off automatically after the time set. This function

can be used, for example, as a command for lights, for anti-fogging

resistances, or for other utilities.

4.13 - ALARM FUNCTIONS

All the parameters regarding the alarm functions are contained in

the “

]

AL” group.

Le alarm functions of the appliance act on the internal buzzer, if one

is present and configured by means of the “buF” par., and on the

desired output, if it is configured by means of the “Out1”, “Out2”,

“Out3” or “Out4” parameters, in accordance with that which is set in

the aforementioned parameters.

The possible selections of these parameters for the functioning of

signalling alarms are:

= ALt - when it is wished that the buzzer or the output be activated

under an alarm condition and that they can be manually deactivated

(alarm silencing) by pressing any key on the appliance (typical

application for an acoustic signal).

= AL - when it is wished that the buzzer or the output be activated

under an alarm condition but that they cannot be manually

deactivated and are hence deactivated only at the cessation of the

alarm condition (typical application for a luminous signal).

= ALL - when it is wished that the buzzer or the output be activated

under an alarm condition and that they remain activated also after

the cessation of the alarm condition (see alarm memory). The

deactivation (recognition of the alarm memorized) may then occur

manually by pressing any key only after the alarm has terminated

(typical application for a luminous signal).

= -ALt - when it is wished to have the operation described as ALt

but with inverse operating logic (buzzer or output activated under

normal condition and deactivated under an alarm condition).

= -AL - when it is wished to have the operation described as AL but

with inverse operating logic (buzzer or output activated under

normal condition and deactivated under an alarm condition).

= -ALL - when it is wished to have the operation described as ALL

but with inverse operating logic (buzzer or output activated under

normal condition and deactivated under an alarm condition).

Any active alarm condition is signalled on the display of the

appliance by switching on the ALARM LED.

Any silenced or memorized alarm condition is signalled by the

ALARM LED flashing.

The alarm conditions of the appliance are:

- Errors in Sensors “E1”, “-E1”, “E2, “-E2”, “E3”, “-E3”, “E4”, “-

E4”

- Temperature alarms “HI 1”, “LO 1”, “HI 2”, “LO 2”, “HI 3”, “LO

3”, “HI 4”, “LO 4”

- External alarm “AL”

- Door open alarm “AdoP”

4.13.1 - TEMPERATURE AND HUMIDITY ALARMS

The temperature and humidity alarms act on the basis of the

measurement of the Pr1, Pr3 (temperature) and Pr4 (humidity)

sensors, of the type of alarm set in the “Aty1”, “Aty2”, and “Aty4”

parameters,of the alarm thresholds set in the “HAL1”, “HAL3”,

and “HAL4” parameters (maximum alarms), “LAL1”, “LAL3”, and

“LAL4” parameters (minimum alarms), and of the related

intervention differentials “dAL1”, “dAL3”, and “dAL4”.

Using the “Aty ” parameters, it is possible to establish whether the

“HAL” and “LAL” alarm thresholds should be considered as absolute

(“Aty”=Ab) or relative to the active Set Point (“Aty”=dE).

In the event of relative alarms referring to the Pr1 and Pr3 inputs,

the relative Set point will be the active temperature Set point “SPt”,

while for the Pr4 input, it will be the active humidity Set point “SPh”.

Some parameters may also be used to delay the enabling and the

intervention of these alarms.

These parameters are:

“PAL1”, “PAL3”, and “PAL4 - are the exclusion times for the

temperature (1,3) and humidity (4) alarms from the switching on of

the appliance whenever the appliance is under alarm conditions

when switching on.

“ALd1”, “ALd3”, and “ALd4” - are the times of the delays in

actuating the temperature (1,3) and humidity (4) alarms

“dAd1”, “dAd3”, and “dAd4” - are the exclusion times of the

temperature (1,3) and humidity (4) alarms from the opening of the

door.

“dALd” - is the exclusion time of the temperature alarms referring

to the Pr1 input after the end of a defrosting cycle (and, if

programmed, also of the dripping cycle).

The alarms are enabled upon the expiry of the exclusion times and

activate after the “ALd” time when the temperature or humidity

measured by the related sensor rises above or falls below the

respective maximum and minimum alarm thresholds.

The alarm thresholds will be the same as those set in the “HAL” and

LAL” parameters if the alarms are absolute (“Aty”=Ab),

At the same time as the alarm signal configured (buzzer and/or

output), the appliance signals the alarm by switching on the ALARM

LED, and showing on the display:

- HI 1 in the case of maximum Pr1 temperature alarm

- LO 1 in the case of minimum Pr1 temperature alarm

- HI 3 in the case of maximum Pr3 temperature alarm

- LO 3 in the case of minimum Pr3 temperature alarm

- HI 4 in the case of maximum Pr4 humidity alarm

- LO 4 in the case of minimum Pr4 humidity alarm

The error message will be displayed alternatively on the display

which normally shows the variable that the alarm refers to.

If the display does not normally show the variable that the alarm

refers to, the alarm message will be shown on the upper display

alternating with the variable established in the “diSU” par..

Ascon Tecnologic Srl - X33H – OPERATING INSTRUCTIONS – MX33HENG00 - PAGE 9

4.13.2 - EXTERNAL ALARM

The appliance may signal an external alarm by activating a digital

input with function programmed as “diF ” = 1, 2, 3, 4 (see digital

inputs).

At the same time as the alarm signal configured (buzzer and/or

output), the appliance signals the alarm by switching on the ALARM

LED, and alternately showing on the upper display AL and the

variable established in the “diSU” par..

4.13.3 - DOOR OPEN ALARM

The appliance may signal a door open alarm by activating a digital

input with function programmed as “diF ” = 5, 6, 7 (see digital

inputs).

Upon the activation of the digital input and after the delay

programmed in the “oAd” par., the appliance signals the alarm by

activating the buzzer and the output (if present), switching on the

ALARM LED, and alternately showing on the upper display “AdoP”

and the variable established in the “diSU” par..

If the operation of the digital input envisages the blocking of some

loads (recycling fans etc.) upon the triggering of the door open

alarm, the utilities are reactivated even if the digital input remains

active.

4.13.4 - ALARM MEMORY

The appliance offers the possibility of availing of the alarm memory

function by means of the “tAL” par..

If "tAL" = no, the appliance cancels the alarm signal when the alarm

conditions have ceased; if, however, it is programmed as "yES", the

ALARM LED continues to flash after the cessation of the alarm

conditions, too, to indicate that an alarm has been signalled.

To cancel the alarm memory signal, press any key.

Remember that if it is wished to have the operation of an output (or

the buzzer) with alarm memory (=ALL or =-ALL), it is necessary to

set the “tAL” par. = yES.

4.14 - OPERATION OF THE “U”, “UP/F1, AND “DOWN/F2”

KEYS

Three of the keys of the appliance can be configured to operate

other commands, in addition to their normal functions.

The function of the U key can be defined using the “USrb”

parameter, that of the UP/F1 key using the “Fbu” par., and that of

the DOWN/F2 key by means of the “Fbd” par., all contained in the

“

]

PAn” group.

The three parameters offer the same possibilities and can be

configured for the following operations:

= OFF - the key does not carry out any function.

= 1 - Pressing the key for at least 1 sec. it is possible to

activate/deactivate the light output (LIGH)

= 2 - Pressing the key for at least 1 sec. it is possible to

activate/deactivate the auxiliary output (AUS) configured as

“FOA”=2.

= 3 - Pressing the key for at least 5 sec. it is possible to

activate/deactivate the manual defrosting cycles.

= 4 - Pressing the key for at least 1 sec. it is possible to switch the

appliance from the ON state to the Stand-by state and vice versa.

= 5 - Pressing the key for at least 1 sec. it is possible start/stop an

air recycling cycle.

= 6 - Pressing the key for at least 1 sec. it is possible start/cancel

(START/STOP) a work cycle.

= 7 - Pressing the key for at least 1 sec. it is possible start/stop

(START/PAUSE) a work cycle. In this mode, by keeping the key

pressed for 5 sec. it is possible to cancel the cycle in progress

(STOP).

4.15 - DIGITAL INPUTS

All the parameters regarding the functions of the digital inputs are

contained in the “

]

din” group.

The appliance envisages up to 3 digital inputs for contacts free from

voltage, of which one is always available while the other 2 can be

used as an alternative to the Pr2 and Pr3 sensors.

The use of these inputs as digital inputs is established by the setting

of the “Pr2” and “Pr3” parameters = diG.

The functions carried out by the digital inputs can be defined by

means of the “diF1”, “diF2”, and “diF3” parameters, and the

actions can be delayed with the times set respectively in the

“did1”, “did2”, and “did3” parameters.

The “diF” parameters can be configured for the following operations:

= 0 - Digital input not active

= 1 - Signalling of an external alarm with contact normally open:

upon the closure of the input (and after the “did” time), the alarm is

activated and the appliance alternately shows on the upper display

AL and the variable established in the “diSU” par..

= 2 - Signalling of an external alarm with deactivation of all the

control outputs by means of normally open contact: upon the

closure of the input (and after the “did” time), all the control outputs

(HEAt, CooL, rh, drh, FAnr, FanE, dEF, AuS) are deactivated, the

alarm is activated and the appliance alternately shows on the upper

display AL and the variable established in the “diSU” par..

= 3 - Signalling of an external alarm with deactivation of the HEAt

output by means of normally open contact: upon the closure of the

input (and after the “did” time), the HEAt output is deactivated, the

alarm is activated and the appliance alternately shows on the upper

display AL and the variable established in the “diSU” par..

= 4 - Signalling of an external alarm with deactivation of the CooL

output by means of normally open contact: upon the closure of the

input (and after the “did” time), the CooL output is deactivated, the

alarm is activated and the appliance alternately shows on the upper

display AL and the variable established in the “diSU” par..

= 5 - Cell door open with only light switching on: upon the activation

of the input (and after the “did” time), the output configured as LIGh

is activated and the appliance alternately shows on the upper

display AdoP and the variable established in the “diSU” par.. With

this operating mode, the action of the digital input also activates the

time that can be set in the "oAd" par., upon the expiry of which the

alarm is activated to signal that the door has remained open. When

the input is deactivated, the LIGH output is switched off. If the

LIGHT output has already been activated by means of a configured

key (see operation of keys), the state of the input has no effect and

the output must be switched off using the key.

= 6 - Cell door open with light switching on and stoppage of

recycling fans by means of normally open contact: upon the

activation of the input (and after the “did” time), as well as the light

switching on (see “diF”= 5), the recycling fans (FAnr) are stopped

and the appliance alternately shows on the upper display AdoP and

the variable established in the “diSU” par.. As in the previous mode,

the action of the digital input also activates the time that can be set

in the "oAd" par., after which the alarm is activated to signal that the

door has remained open. On the occurrence of the door open

alarm, the recycling fans are then re-started.

= 7 - Cell door open with light switching on and with stoppage of

fans and actuators by means of normally open contact: similar to

“diF” = 6 but with disabling of both the recycling fans (FAnr) and the

actuators (HEAt. CooL, rh, drh). On the occurrence of the door open

alarm, the recycling fans and the actuators are then re-enabled.

= 8 - Start defrosting command with normally open contact: upon

the closure of the input (and after the “did” time), a defrosting cycle

is activated.

= 9 - End defrosting command with normally open contact: upon the

closure of the input (and after the “did” time), the defrosting cycle is

terminated if it is in progress, or defrosting is blocked.

= 10 - Switch on/Switch off(Stand-by) of the appliance with normally

open contact: upon the closure of the input (and after the “did”

time), the appliance is switched on, while when it is opened, the

appliance is put into the Stand-by state.

Upon switching off, this command has priority over the key, thus if a

digital input is programmed = 10 and the input is not active, the

controller cannot be switched on by the key. However, if the input

remains active, the controller can be switched on/off using the

configured key, but when the input is deactivated, it is in any case

switched off.

= 11 - Air exchange cycle enabling command with normally open

contact: upon the closure of the input (and after the “did” time), a

work cycle is activated.

If the work cycle is already in progress, the command interrupts the

air exchange cycle in progress.

Ascon Tecnologic Srl - X33H – OPERATING INSTRUCTIONS – MX33HENG00 - PAGE 10

= 12 - Auxiliary output AUS remote command with normally open

contact: upon the closure of the input (and after the “did” time), the

auxiliary output is activated as described in the "FOA" = 2 operating

mode of the auxiliary output.

= 13 - Work cycle command with START/STOP mode with normally

open contact: upon the closure of the input (and after the “did”

time), the cycle is started (START). Once the cycle has been

started, the digital input can be deactivated. If the digital input is

reactivated during the execution of the cycle, the cycle is interrupted

and the appliance returns to the normal regulation state (STOP).

= 14 - Work cycle command with START/PAUSE mode with

normally open contact: upon the closure of the input (and after the

“did” time), the cycle is started (START). Once the cycle has been

started, the digital input can be deactivated. If the digital input is

activated again during the execution of the cycle, the controller

stops the counting of the time in progress maintaining the regulation

with the values set in the phase in progress (PAUSE). At this stage

it is possible to restart the cycle from the point when it was stopped,

by reopening and reclosing the digital input, and use further

activations and deactivations to stop it, restart it and so on.

= 15 - Stop work cycle command with normally open contact: upon

the closure of the input (and after the “did” time), the work cycle in

progress is interrupted (STOP). In this mode, if the command is

maintained, it is not possible to start work cycles.

= -1, -2, -3 .....-15 - Commands similar to the previous ones but

obtained with normally closed contacts and hence with inverse

operating logic.

4.16 - WORK CYCLES AND DESCRIPTION OF TWO TYPICAL

APPLICATIONS

The appliance allows timed work cycles to be executed, which can

be used in many applications including the control of climatic

chambers, curing cells, or leavening-retarding/leavening cabinets.

All the parameters regarding the programming of the work cycle are

contained in the “

]

PrG” group.

The programmable work cycle consists of three phases indicated as

1., 2., and 3., and for each phase, the following are programmable:

the Duration (“tS1”, “tS2”, and “tS3” parameters), the temperature

regulation Set Point (“SPt1”,”SPt2”, and “SPt3” parameters) and

the Humidity regulation Set Point (“SPh1”, ”SPh2”, and “SPh3”

parameters).

In the event that it is wished to use a lower phase number, it is

sufficient to program the time of the phase not to be executed =

OFF.

For example, if it is wished to carry out the cycle with only two

phases, program “tS3” = OFF.

Conversely, if it is wished that the control of the variable does not

occur during a phase, set the related Set Point = OFF.

For example, if it is not desired to control the humidity in phase .2,

set “SPh2” = OFF.

When the cycle is not active, the regulator operates with the normal

“SPt” and “SPh” Set Points described previously.

In the event that no control is desired apart from the programmed

cycle, set “SPt” and “SPh” = OFF.

The start/stop cycle commands can be provided by the keys of the

appliance or by the digital inputs, if the relative parameters are

opportunely programmed.

By keys through the “USrb”, “Fbu” and “Fbd” parameters as:

= 6 - START / STOP mode

When the command is given by key, the cycle is started (START)

If the key is pressed for approximately 1 sec. during the execution

of the cycle, the cycle is interrupted and the appliance returns to the

normal regulation state (STOP).

= 7 - START / PAUSE + STOP mode

When the command is given by key, the cycle is started (START).

If the key is pressed for approximately 1 sec. during the execution

of the cycle, the controller stops the counting of the time in progress

maintaining the regulation with the values set in the execution

phase (PAUSE).

At this stage, if the key is pressed again for 1 sec., it is possible to

restart the cycle from the point when it was stopped, and, each time

it is pressed again for 1 sec., to stop and restart it and so on.

If it is wished to interrupt the cycle, keep the key pressed for 5 sec.,

after which the appliance returns to the normal regulation state

(STOP).

By digital inputs through the “diF1”, “diF2”, and “diF3”

parameters as:

= 13 - START / STOP mode

When the command is given by digital input, the cycle is started

(START).

Once the cycle has been started, the digital input can be

deactivated.

If the digital input is reactivated during the execution of the cycle,

the cycle is interrupted and the appliance returns to the normal

regulation state (STOP).

= 14 and 15 - START / PAUSE (14) + STOP (15) modes

Upon the activation of the digital input configured =14, the cycle is

started (START). Once the cycle has been started, the digital input

can be deactivated.

If the digital input is activated again during the execution of the

cycle, the controller stops the counting of the time in progress

maintaining the regulation with the values set in the execution

phase (PAUSE)

Once the cycle has been paused, the digital input can be

deactivated.

At this stage it is possible to restart the cycle from the point when it

was stopped, reactivating the digital input, and with further

activations and deactivations, stop and restart it and so on.

If it is wished to interrupt the cycle, activate the digital input

configured =15 and the appliance returns to the normal regulation

state (STOP).

If the STOP command is pressed and held, it is not possible to start

work cycles.

During the execution of the cycle, the lower display of the appliance

shows the message “1.”, “2.” or “3.” indicating the phase in

progress alternated with the normal programmed display.

If the cycle is paused, the lower display of the appliance shows the

message “1.P”, “2.P” or “3.P” indicating the phase in progress

alternated with the normal programmed display.

During the execution of the cycle, the normal procedure for the

rapid setting of the Set Points allows the modification of the

temperature and humidity Sets relating to the phase in execution,

as well as the residual time in relation to the phase in progress.

During the execution of the cycle, by pressing and releasing the P

key several times, the appliance will display in sequence “SPt1” (or

2 or 3), “SPh1” (or 2 or 3) and “tr 1” (or 2 or 3), and the related

value that can be modified with the UP or DOWN keys.

The modification of the time “tr 1” (or 2 or 3) then allows the

duration of the phase in progress to be increased, or decreased to

0, thus obtaining the passage to the following step.

Note that the modified temperature and humidity Set values are

also memorized and thereafter used for all future cycles, while the

modification of the time refers only to the phase in progress.

If a cycle has been started and the power supply is interrupted and

subsequently returns, the appliance returns to execute the cycle

from the beginning of the phase in progress at the moment the

power was cut.

However, if the appliance is switched off by means of the stand-by

command, the cycle in progress is cancelled and, when

subsequently restarted, the regulator returns to operating in normal

mode on the “SP t” and “SP h” Sets.

Ascon Tecnologic Srl - X33H – OPERATING INSTRUCTIONS – MX33HENG00 - PAGE 11

Using the “ECS” parameter it is possible to establish the behaviour

of the regulator at the end of the cycle.

The possible settings of the parameter are:

1= the appliance returns to the normal regulation with the “SP t”

and “SP h” Sets without giving any signalling of end of cycle.

2= The appliance returns to the normal regulation with the “SP t”

and “SP h” Sets signalling the “End” message on the lower display

and activating the internal buzzer and the output configured as

“End” for the time programmed in the “btEd” par..

3= The appliance automatically goes to Stand-by state without

giving any signalling of end of cycle.

4= The appliance automatically goes to Stand-by state signalling

the “End” message on the lower display and activating the internal

buzzer and the output configured as “End” for the time programmed

in the “btEd” par..

5 = The appliance continues to regulate on step3 without giving any

signalling of end of cycle.

6 = The appliance continues to regulate on step3 signalling the

“End” message on the lower display and activating the internal

buzzer and the output configured as “End” for the time programmed

in the “btEd” par..

7 = The appliance begins to regulate again from step 2 and

continues to carry out the cycle until interrupted manually.

8 = The appliance begins to regulate again from step 1 and

continues to carry out the cycle until interrupted manually.

4.16.1 - CONTROL FOR APPLICATIONS ON “LEAVENING-

RETARDING / LEAVENING CABINETS”

The application envisages an initial cooling phase also known as

“blast chilling” (in which the humidity variable is not normally

controlled) for the purpose of stopping leavening and thus

preserving the product in optimum state while it awaits processing

and subsequent operations.

The second phase envisages a heating action, which is intended to

favour the leavening of the product, and the control of the humidity.

At the end of the second phase, the product is ready to be

processed and hence the cycle can be interrupted.

However, in the event that it is envisaged that the operator cannot

be present at the end of this phase, and thus cannot extract the

product, it is possible to program a third maintenance phase.

For this third phase, it is possible to program a duration in the “tS3”

par. (at the end of which a signal is given) and then make the

appliance continue to regulate with the same Set Point values (by

programming “ECS” = 6) until the user interrupts the cycle

manually.

4.16.2 - CONTROL FOR APPLICATIONS ON “CURING” CELLS

The application envisages an initial cooling phase also known as

“dripping” in which the humidity is not normally controlled) for the

purpose of rapidly cooling the product arriving from processing, and

at the same time rapidly eliminating the humidity in excess.

The second phase envisages the control of temperature and

humidity at established values and for this reason is also known as

“running”.

The third phase, on the other hand, does not typically envisage any

controlling action of the temperature and humidity variables, and for

precisely this reason, it is also called “break”.

Note: the example shows the temperature and humidity Set Points

= OFF; however, these can obviously be set at whatever value the

user wishes.

At the end of the third phase, the cycle resumes from phase 2.

(running) and then executes phase 3. (break) again, and so on until

the manual stoppage of the cycle.

Note: to obtain this function of repeating the cycle from phase 2., it

is necessary to set the “ECS” par. = 7
