INSTRUMENT ORDERING CODE
1 - INSTRUMENT DESCRIPTION
1.1 - GENERAL DESCRIPTION
The model COMPACT is a digital controller with
microprocessor that is typically used in cooling applications that
have temperature control with ON/OFF regulation and
defrosting control with set time by means of electrical heating
or hot gas/reverse cycle. The instrument has up to 4 relay
outputs, two inputs for PTC or NTC temperature probes and a
digital input, that can all be configured.
The 4 outputs can be used for controlling the compressor or the
temperature control device (OUT), the defrosting device (DEF),
the evaporation fan (FAN), the room light (LIGHT) or,
alternatively any of the previous functions, using an auxiliary
device (AUX) or an alarm (AL). The two inputs for the PTC and
NTC temperature probes (which can be selected by parameter)
can be used to measure the cell temperature (Pr1) and the
evaporator temperature (Pr2) while the digital input (DIG) can
be programmed to carry out various functions such as
defrosting commands, selecting a different set of temperature
regulations, external alarm signals, activating a continuous
cycle, and activating an auxiliary output etc.
The instrument is equipped with 7 programme keys, a 4-digit
display and 9 LED signals, in addition to an internal buzzer that
is the sound system for alarms. Other important characteristics
of the instrument are: programme parameters protection using
personalised password, Keyboard lock function, switching on
and off (stand-by) of the instrument using the front keys or the
digital input, configuration of parameters via the KEY USB
device, memorising of two sets of temperature regulations that
can be switched and the possibility of power supply in the
range 100 ... 240 VAC.

2 -PROGRAMMING
2.1 - PROGRAMMING OF THE SET POINT
Press the key Pthen release it and the display will show SP 1
(or SP 2 if the second set is active at that time) alternating with
the set value (see selection of the active set point).
To change it press the UP key to increase the value or DOWN
to decrease it.
These keys increase or decrease the value one digit at a time,
but if the button is pressed for more than one second the value
increase or decreases rapidly, and after two seconds pressed,
the speed increases even more to all the desired valued to be
reached rapidly.
Exiting the Set mode is achieved by pressing the P key or
automatically if no key is pressed for 15 seconds. After that
time the display returns to the normal function mode.
2.2 - PARAMETERS PROGRAMMING
To access the instrument’s function parameters, press the key
Pand keep it pressed for about 5 seconds, after which the SET
led will light up, the display will visualised the code that
identifies the first group of parameters (“]SP “) and the group of
parameters that are to be edited are selected by pressing the
UP and DOWN keys.
Once the group of parameters has been selected, press the P
and the code that identifies the first parameter in the selected
group will be visualised.
Again using the UP and DOWN keys, the desired parameter
can be selected and pressing the P key, the display will
alternately show the parameter code and its setting that can be
changed with the UP and DOWN keys.
Once the desired value has been set, press the key P again:
the new value will be memorised and the display will show only
the abbreviation of the selected parameter.
Pressing the UP and DOWN keys, it is possible to select
another parameter (if present) and change it as described.
To return to select another group of parameters, keep the UP
or the DOWN key pressed for about 1 second, after which the
display will return to showing the code of the parameter group.
Release the pressed key and using the UP and DOWN keys it
will be possible to select another group (if present).
To exit the programming mode, do not press any key for about
20 seconds, or keep the UP or DOWN key pressed until it exits
the programming mode.

2.3 - PARAMETER PROTECTION USING THE PASSWORD
AND KEYBOARD LOCK FUNCTION
The instrument has a parameter protection function using a
password that can be personalised, through the “PASS”
parameter in the “]PAn” set.
If one wishes to have this protection, set the password number
desired in the parameter “PASS”.
When the protection is working, press the P key to access the
parameters and keep it press for about 5 seconds, after which
the LED SET will flash and the display will show “0” .
At this point, using the UP and DOWN keys, set the password
number programmed and press the key "P".
If the password is correct, the display will visualise the code
that identifies the first group of parameters(“]SP “) and it will be
possible to programme the instrument in the same ways
described in the previous section.
Protection using a password can be disabled by setting the
parameter “PASS” = OFF.
Additionally to the protection through the Password, it’s
possibile to lock completely the keyboard.
This function is particularly useful when the regulator is
reachable by the users and it’s desired to avoid any
modification.

OSAKA –OPERATING INSTRUCTIONS –COMPACT –v.2 –PAG. 3
To activate the keyboard lock it’s enough to contemporarily
push key UP and DOWN and keep them pushed for 3 sec.
while the regulator is on.
After the 3 sec., the label “LOn” will appear on the display and
all the key functions will be locked except the Set Point
visualization.
When the keyboard is lock, if any of the key is pushed, on the
display will appear again “LOn” to indicate the lock.
To unlock the keyboard it’s enough to contemporarily push
again key UP and DOWN and keep them pushed for 3 sec.,
afterwhich the label “LOF” will appear on the display and all
the functions will be available again to be modified.
2.4 - PARAMETERS PROGRAMMING LEVELS
The instrument has two parameter programming levels.
The first level (“visible” parameters) is accessed according to
the procedure described above (with or without password
request) while the second level (“hidden” password) can be
accessed according to the following procedure.
Remove the power supply to the instrument, press the key P
and return power to the instrument, keeping the key pressed.
After about 5 sec. the SET led will light up, the display will show
the code that identifies the first group of parameters(“]SP “) and
it will be possible to set the parameters of the instrument using
the same programming procedure described previously.
Once the parameter has been selected and the SET is on, it
means that the parameter can be programmed even on the first
level ("visible”).
If the LED is off it means that the parameter can only be
programmed on this level (i.e. “hidden”).
To change the visibility of the parameter, press the key U: the
led SET will change status, indicating the accessibility level of
the parameter (on = parameter “visible”; off = parameter
“hidden”).
The access procedure for “hidden” parameters allows the
“PASS” parameter to be checked and changed, and is useful
therefore if the password set has been forgotten.
2.5 - ACTIVE SET POINT SELECTION
The instrument allows up to 2 different regulation Set points to
be pre-set (“SP 1” and “SP 2”) and then to choose which one
to make active.
This function can be used if it is necessary to switch two
different function temperatures (e.g. day and night or positive
and negative etc).
The active set point can be selected:
- Using the parameter “SPAt”
- using the key U if the parameter "USrb" = 2.
- Using the key DOWN/AUX if the parameter "Fbd" = 2.
- Using the digital input if the parameter. “diF” = 9
(see par. 4.12 and 4.14)
The Set points "SP1" and "SP2" can be set with a value
between the programmed value in parameter. “SPLL” and the
programmed value in parameter “SPHL”.
Note: in the examples that follow, the Set point is generally
indicated as "SP", how when operating the instrument will work
according to the Set point selected as active.
2.6 - ON / STAND-BY FUNCTION
The instrument, once powered up, can assume 2 different
conditions:
- ON : means that the controller uses the control functions.
- STAND-BY : means that the controller does not use any
control function except for the Light control and the display is
turned off except for the green SET led.
If there is no power, and then power returns, the system always
sets itself in the condition it was in before the black-out.
The ON/Stand-by function can be selected:
- Using the key ON/OFF hold for 1 sec.
- Using the digital input if the parameter “diF” = 11 (see par.
4.12)
3 - INFORMATION ON INSTALLATION AND USE
3.1 - PERMITTED USE
The devices are made as measuring and regulating
equipment in accordance with EN 61010-1 norm for
operation up to an altitude of 2000 mts.
The use of equipment for standard applications not expressly
provided in norm cited above, should provide all measurement
and adjustments necessary protection.
The equipment must be adequately protected and away from
liquids, dust, grease and dirt. They must be accessible only
with the use of a right tool and safety system (except the front).
The devices can NOT be used in dangerous environments
(flammable or explosive) without adequate protection.
It is recalled that the installer must ensure that the norm for
electromagnetic compatibility is respected after implantation in
the installation of equipment, eventually using the right filters if
is needed.
In case of failure or malfunction of measuring and control
equipment that can create dangerous situations or damage to
persons, things, animals or products (defrost food or changes
in their ideal state), it is recalled that the facility should be
equipped with electronic devices or electromechanical safety
and warning system.
They should be placed outside the measuring and control
equipments, possible protective devices, responding to specific
safety requirements that are covered by the norm of the
product or suggest the common sense.
For your own safety, is highly recommended fulfilling the
instructions provided above.
3.2 - MECHANICAL MOUNTING
The instrument, in case 185 x 37 mm, is designed for flush-in
panel mounting.
Make a hole 150 x 31 mm, insert the instrument, fixing it with 2
screws and to apply the provided special covers.
We recommend that the gasket is mounted in order to obtain
the front protection degree as declared. Avoid placing the
instrument in environments with very high humidity levels or dirt
that may create condensation or introduction of conductive
substances into the instrument.
Ensure adequate ventilation to the instrument and avoid
installation in containers that house devices which may
overheat or which may cause the instrument to function at a
higher temperature than the one permitted and declared.
Connect the instrument as far away as possible from sources
of electromagnetic disturbances such as motors, power relays,
relays, solenoid valves, etc.
3.3 - ELECTRICAL CONNECTION
Carry out the electrical wiring by connecting only one wire to
each terminal, according to the following diagram, checking
that the power supply is the same as that indicated on the
instrument and that the load current absorption is no higher
than the maximum electricity current permitted.
As the instrument is built-in equipment with permanent
connection inside housing, it is not equipped with either
switches or internal devices to protect against overload of
current: the installation will include an overload protection and a
two-phase circuit-breaker, placed as near as possible to the
instrument, and located in a position that can easily be reached
by the user and marked as instrument disconnecting device
which interrupts the power supply to the equipment.
It is also recommended that the supply of all the electrical
circuits connected to the instrument must be protect properly,
using devices (ex. fuses) proportionate to the circulating
currents.
It is strongly recommended that cables with proper insulation,
according to the working voltages and temperatures, be used.
Furthermore, the input cable of the probe has to be kept
separate from line voltage wiring. If the input cable of the probe
is screened, it has to be connected to the ground with only one
side.

OSAKA –OPERATING INSTRUCTIONS –COMPACT –v.2 –PAG. 4
We recommend that a check should be made that the
parameters are those desired and that the application functions
correctly before connecting the outputs to the actuators so as
to avoid malfunctioning that may cause irregularities in the
plant that could cause damage to people, things or animals.

4 - FUNCTIONS
4.1 - MEASURING AND VISUALIZATION
All the parameters concerning measuring are contained in the
group “]InP”.
Via the parameter “SEnS” it is possible to select the type of
probes that one wishes to use and which can be: thermistores
PTC KTY81-121 (Ptc) or NTC 103AT-2 (ntc).
Once the type of probe used has been selected, through the
parameter “Unit”, it is possible to select the temperature unit
of measurement (°C or °F) and, through the parameter “dP”,
the resolution of the desired measurement (OFF=1°; On =0,1°).
The instrument allows the measuring to be calibrated, that can
be used for re-calibrating the instrument according to
application needs, through the parameters “OFS1” (for the
probe Pr1) and “OFS2” (for the probe Pr2).
If probe Pr2 (evaporator) is not used, set the parameter “Pr 2”
= OFF.
Using the parameter “FiL”, it is possible to set the time
constant for the software filter for measuring the input values to
be able to reduce the sensitivity to measurement disturbances
(increasing the time).
Through the paragraph “diSP”, it is possible to fix the normal
visualisation on the display that can be the measurement of the
cell probe (Pr 1), the measurement of the evaporator probe (Pr
2), the set point of active regulation (SP) or it can have the
numerical display switched off (OFF).
Regardless of what is set in the parameter “diSP”, it is possible
to visualise all the variables in rotation by pressing the key U,
the display will alternately show the code that identifies the
variable (Pr 1, Pr 2) and its value.
The exit of this visualisation mode occurs automatically 15
seconds after the last pressing on the key U.
Please remember that visualisation of the probe Pr1 can be
changed by the display block in defrosting function too, by
using the parameter “dLo” (see par. 4.7).
4.2 - ROOM PROBE PEAK VALUES MEMORIZATION
The instrument memorizes the highest and lowest peak room
probe (Pr1) measurement values.
To visualize such values simply press the UP key and release it
to visualize the highest peak (blinked ad signalled by led + on)
or the DOWN key and release it for the lowest peak (blinked
and signalled by led - on) during normal operation of the
instrument.
After 5 sec. or by press the key UP or DOWN the display come
back to normal mode.
When the instrument is switched off, such values are always
re-set. However, it is also possible to reset these values if the
instrument is switched on by using the P key hold for 2 sec.
during peak visualization.
The display will show “r.Pic” and peaks memory will be reset.
4.3 - OUTPUTS CONFIGURATION
The instrument outputs can be configured in the parameters
group “]Out” where the relative parameters “Out1” , “Out2”
“Out3” and “Out4”.
The outputs can be configured for the following functions:
= Out - to control the compressor or however, the temperature
control device
= dEF - to control the defrosting device
= FAn - to control the fans
= LIGH - to control the light
= AuS - to control the auxiliary device (see par. 4.13)
= ALt - to control a silenceable alarm device through a contact
that is normally open, and then closed when the alarm sounds
= AL - to control an alarm that cannot be silenced through a
contact that is normally open and closed when the alarm
sounds.
= ALL - to control an alarm with a memory function through a
contact that is normally open and closed when the alarm
sounds.
= -ALt - to control a silenceable alarm device through a contact
that is normally closed, and then open when the alarm sounds.
= -AL - control an alarm that cannot be silenced through a
contact that is normally closed and open when the alarm
sounds.
= -ALL - to control an alarm with a memory function through a
contact that is normally closed and open when the alarm
sounds (see par. 4.11.4).
= On - Output on when the instrument is in on state. This mode
can be used to control non-misting resistance on room door or
other utilities
= OFF - Disabled output
4.4 - TEMPERATURE CONTROL
All the parameters concerning temperature regulation are
contained in the group “]rEG”.
The regulation of the instrument is ON/OFF and acts on the
output configured as “Out” depending on the measuring of
probe Pr1, of the active Set Point “SP” (1 or 2), the intervention
differential “HSEt” and the function mode “Func” .
Depending on the function mode programmed on the
parameter “Func” the differential is automatically considered by
the regulator with positive values for a Refrigeration control
(“Func”=CooL) or with negative values for a heating control
(“Func”=HEAt).

In the event of cell probe error (Pr1), it is possible to set the
instrument so that that the output “Out” continues to work in
cycles according to the times programmed in the parameter
“tonE” (activation time) and “toFE” (deactivation time).
If an error occurs on the probe Pr1 the instrument activates the
output for the time “tonE”, then deactivates it for the time “toFE”
and so on whilst the error remains.
Programming “tonE” = OFF lthe output in probe error condition
will remain switched off.
Programming instead “tonE” to any value and “toFE” = OFF the
output in probe error condition will remain switched on.

OSAKA –OPERATING INSTRUCTIONS –COMPACT –v.2 –PAG. 5
Remember that the temperature regulation function can be
conditioned by the “Continuous Cycle”, “Compressor
Protection”, “Minimum compressor function time”, “Delay
compressor start up after defrosting” and “inhibition of
compressor close to defrosting” functions described below.
4.5 - CONTINUOUS CYCLE FUNCTION
The instrument has a continuous cycle function by which it is
possible to maintain the configured output configured as “out”
always active for the time set in parameter “tCC” (in the group
“]rEG”) regardless of the temperature control command.
The function can be used for example, when rapid lowering of
the product temperature is required after the refrigerator
loading phase.
During the continuous cycle, the defrosting is inhibited and the
temperature alarms are disabled during the entire cycle and
also later for the time set in parameter “dALc” (see par.
4.11.1).
Starting up a continuous cycle can only be done by a manual
command using the UP/CONT.CYCLES key or via the digital
input (“diF”=3) if suitably programmed (see par. 4.12).
The continuous cycle in progress is shown on the display with
the indication CC and can be stopped by a further action on the
key or digital input (as for activation).
The continuous cycle function cannot be activated during
defrosting and with "tCC" = OFF.
4.6 - COMPRESSOR PROTECTION FUNCTION AND DELAY
AT POWER-ON
All the parameters concerning the compressor protection
functions and the delay at power on are contained in the group
“]PrC”.
The function “Compressor Protection” carried out by the
machine aims to avoid close start ups of the compressor
controlled by the instrument in cooling applications.
This function foresees a time control on the switching on of the
“Out” output associated with the temperature regulation
request.
The protection consists of preventing the output being switched
on during the time set in the parameter “PtC” and counted
depending on what has been programmed in the parameter
“PSC”, and therefore that any activation occurs only after the
“PtC” time has finished.
If during the power on delay phase, the regulator request
should disappear, due to an inhibition caused by the
compressor protection function, the foreseen start up of the
output is naturally cancelled.
Using the parameter "PSC", it is possible to set the type of
compressor protection and therefore from when the inhibition
time “PtC” must start.
The parameter “PSC” can be set as:

Through the parameter “LCt” it is also possible to set the
minimum activation time of the output to avoid switching on of
the compressor that is too short.
During the power on delay phases of the OUT output by
inhibiting the function “Compressor Protection” or delay of
power off caused by the minimum function time “LCt”, the led
OUT flashes.
It is also possible to prevent activation of all the outputs after
the instrument is turned on, for the time set in the parameter
“od”.
During the power on delay phase, the display shows the
indication od, alternating with the normal programmed
visualisation.
All timer functions are disabled by set relative parameters =
OFF.
4.7 - DEFROST CONTROL
All the parameters concerning the defrosting control that acts
on the outputs configured as “Out” and “dEF”, are container in
the group “]dEF”.
The type of defrosting that the instrument must carry out is set
by the parameter “dtyP” that can be programmed:
= EL - WITH ELECTRICAL HEATING or BY STOPPING
COMPRESSOR (during defrosting, the output “Out” is
deactivated while the output “dEF” is enabled)
= in - WITH HOT GAS or INVERSION OF CYCLE (during
defrosting the outputs “Out” and “dEF” are enabled)
The automatic defrosting can take place at intervals.
Defrosting at intervals is possible by setting the time that runs
between the two next automatic defrostings in the parameter
“dint”.
Counting this interval is set through the parameter "dCt" that
can be programmed:
= rt - counts the total function time (instrument on)
= ct - counts only the compressor function time (output OUT
switched on)
= cS - the instrument carries out a defrosting cycle at each
compressor stop (i.e. at each deactivation of the output OUT).
If this option is used, set “dint”=OFF.
The automatic defrosting cycle can be ended by time or, if an
evaporator probe is used (Pr2), when a temperature is reached.
If the evaporator probe is not used (par. “Pr 2” = OFF) the
duration cycle is set by the parameter “dEFE”.
If instead the evaporator probe is used (parameter “Pr 2” = on)
the defrost end when the temperature measured by the probe
exceeds the temperature set in the parameter “tEdF”.
If this temperature is not reached in the time set in the
parameter “dEFE”, defrosting is interrupted.
In order to avoid pointless defrosting the parameter. “tSdF” is
foreseen that sets the enablement temperature for defrosting
If the temperature measured by the probe is higher than the
one set in the parameter “tSdF” and in the parameter "tEdF"
the defrosting is inhibited.

temperature “tEdF” is not reached, defrosting 3 does not take
place as the temperature is higher than “tSdF”.
At the end of defrosting, it is possible to delay the new start up
of the compressor (output “Out”) at the time set in parameter
“tdCO” to allow the evaporator to drain.
During this delay, the led Def flashes to indicate the draining
state.
If one wishes to set a defrosting cycle every time the instrument
is switched on (as long as the conditions set in the parameters
“tSdF” and "tEdF" apply) programme the parameter “SdEF” =
yES.
This allows the evaporator to be permanently defrosted, even
when frequent interruptions to power supply occur that may
cause the cancellation of the various defrosting cycles.
During the defrosting, it may occur that the temperature
measured by the cell probe (Pr1) increases excessively (this
obviously depends on the position of the probe Pr1 compared
to the evaporator).
In the event that one does not wish this increase to be
visualised by the instrument, it is possible to use the functions
in the parameter “dLo” (Block display during defrosting) and
“Etdu” (Differential unblocking of display after defrosting).
The parameter “dLo” = On allows the temperature Pr1
visualisation to be blocked on the last reading during a whole
defrosting cycle and until the temperature does not return
under the value [”SP” + “Etdu”] after defrosting has finished (or
the time set in the parameter "dALd" contained in the block
“]AL”).
With “dLo” = Lb, this allows visualisation of the writing dEF
during defrosting and at the end of defrosting the writing PdEF
up to when the temperature Pr1 does not return below the
value [”SP” + “Etdu”] (or the time set on the parameter "dALd"
contained in the block “]AL”).
Alternatively with the “dLo” = OFF, during defrosting, the
instrument will continue to visualise the temperature measured
by the probe Pr1.
Note that during defrosting, the temperature alarms are
disabled during the whole cycle and also afterwards for the
time set in the parameter “dALd” (see par. 4.11.1).
4.8 - MANUAL DEFROST
To start up a manual defrosting cycle, press the key DEFROST
and keep it pressed for about 5 seconds after which, if the
conditions are correct, the led DEF will light up and the
instrument will carry out a defrosting cycle.
The start up or switch off commands of a defrosting cycle can
also be given by the digital input that are correctly programmed
(see par. 4.12).
4.9 - EVAPORATOR FANS CONTROL
All the parameters concerning fan control are contained in the
group “]FAn”.
The control of the fans on the output configured as “FAn”
depending on determined control statuses of the instrument
and the temperature measured by the probe Pr2.
In the case that the probe Pr2 is not used (parameter “Pr 2” =
OFF) or in error (E2 o -E2) , the output FAN is activated only
depending on the parameters “FCOF” and “FEdF”.
The parameter “FCOF” decides whether the fans must always
be switched on independently of the compressor status
(“FCOF”=On) or be switched off together with the compressor
(“FCOF”=OFF).
The parameter “FEdF” instead decides whether the fans must
always be switched on independently of the defrosting status
(“FEdF”=On) or switched off during defrosting (“FEdF”=OFF).
In this latter case, it is possible to delay the start up of the fans
even after the end of the defrosting of the time set in the
parameter “Fd”.
When the probe Pr2 is used (par. “Pr 2” = on) the fans, as well
as being conditioned by the parameters “FCOF” and “FEdF”,
are also conditioned by the temperature control.
It is possible to set the disablement of the fans when the
temperature measured by the probe Pr2 is higher than the one
set in the parameter “FLt” (temperature too hot) or when it is
lower than the one set in the parameter “Fct” (temperature too
cold).
The relative differential that can be set in parameter “dF” is
also associated with these parameters.

4.10 - ROOM LIGHT CONTROL
The control of the light on the output configured as “LIGHT” by
LIGHT key or by the digital input that are correctly programmed
at par. “diF” (see par. 4.12).
The LIGHT output it's always actionable also when the
controller is in OFF mode (standby).
If the LIGHT output is activated by LIGHT key the digital input
it doesn't have effect (the output has to be switch off by the
key).
4.11 - ALARM FUNCTIONS
All the parameters concerning the alarm functions are
contained in group “]AL”.
The alarm functions of the instrument work on the internal
buzzer and on the output desired, if configured by the
parameters “Out1”, “Out2” , “Out3” or “Out4”, depending on
what is set on the said parameters.
The possible selections of these parameters for the alarm
signalling function are:
= ALt - when one wants the output to be activated in alarm and
can be disabled (alarm silencing) manually by pressing any key
of the instrument (typical application for sound signal).
= AL - when one wants the output to be activated in alarm
status but cannot be disabled manually and are therefore only
disabled when the alarm status ceases (typical application for a
light signal).
= ALL - when one wants the output to be activated in alarm
status and that they remain activated even when the alarm has
ceased (see par.4.11.4) Disablement (recognition of
memorised alarm) can only be carried out manually by pressing
any key when the alarm has ended (typical application for light
signal).
= -ALt - when one wants the function described as ALt but with
an inverse function (output activated in normal condition and
disabled in alarm status).
= -AL - when one wants the function described as AL but with
inverse logic (output activated in normal conditions and
disabled in alarm status).
= -ALL - when one wants the function described as ALL but
with inverse working logic (output activated in normal
conditions and disabled in alarm status).

OSAKA –OPERATING INSTRUCTIONS –COMPACT –v.2 –PAG. 7
When no alarms are present, the green LED OK is lit.
Any active alarm is shown on the instrument display with the
lighting up of the AL led and the switching off of the led OK.
Any silenced or memorised alarm status is shown by the AL
led flashing .
The alarm conditions of the instrument are:
- Probe errors “E1”, “-E1”, “E2, “-E2”
- temperature alarms “HI” and “LO”
- External alarms “AL”
- Open door alarm “AP”
4.11.1 - TEMPERATURE ALARMS
The temperature alarms work according to the probe Pr1
measurements, the type of alarm set in the parameter “Aty”
the alarm thresholds set in parameters “HAL” (maximum
alarm) and “LAL” (minimum alarm) and the relative differential
“dAL”.
Through the parameter “Aty” it is possible to set the alarm
thresholds “HAL” and “LAL” which must be considered as
absolute (“Aty”=Ab) or relative to the active Set Point
(“Aty”=dE).
Using some parameters it is also possible to delay the
enablement and the intervention of these alarms.
These parameters are:
“PAL” - is the temperature alarm exclusion time on switching
on the instrument if the instrument is in alarm status when it is
switched on.
“dALd” - is the temperature alarm exclusion time at the end of
defrosting (and , if programmed, at the end of draining)
"dALc" - is the temperature alarm exclusion time at the end of
a continuous cycle.
“ALd” - is the temperature alarm delay activation time
The temperature alarm is enabled at the end of exclusion time
and is enabled after the “ALd” time when the temperature
measured by the probe Pr1 exceeds or goes below the
respective maximum and minimum alarm thresholds.
The alarm thresholds will be the same as those set on the
parameters “HAL” and LAL” if the alarms are absolute
(“Aty”=Ab)

The maximum and minimum temperature alarms can be

At the same time as the signalling of the configured alarm
(buzzer and output), the instrument signals the alarm by turning
on the led light AL, switching off the LED OK, turning on the led
- in case of minimum alarm or the led + for maximum alarm,
and visualises on the display:
- Alternately HI and the set variable in parameter “diSP” for
maximum alarm
- Alternately LO and the set variable in parameter “diSP” for the
minimum alarm
4.11.2 - EXTERNAL ALARM
The instrument can signal an external alarm by activating the
digital input with the function programmed as “diF” = 4 or 10
(see par. 4.12).
At the same time as the signalling of the configured alarm
(buzzer and output), the instrument signals the alarm by turning
on the led AL, turning off the led OK and visualising AL and the
variable set in parameter “diSP” alternately on the display.
4.11.3 - OPEN DOOR ALARM
The instrument can signal an open door alarm by activating the
digital input with the function programmed as “diF” = 5, 6, 7
(see par. 4.12).
When the digital input is activated and after the delay
programmed in parameter “oAd”, the instrument signals the
alarm via the activation of the configured devices (buzzer and
output), the turning on of the led AL, the turning off of the led
OK and AP and the variable set in parameter “diSP” are
visualised alternately on the display.
If the function of the digital input foresees the fan or the fan and
compressor switch off at the alarm activation the load will be
reactivated even if the digital input is active.
4.11.4 - ALARM MEMORY
The instrument offers the possibility of arranging the alarm
memory function via the parameter “tAL”.
If "tAL" = no, the instrument cancels the alarm signal when the
alarm status ends, if instead it is programmed as "yES" , the
led AL flashes even when the alarm status has ended to
indicate that there has been an alarm.
If the memorised alarm is for temperature, it also keeps the led
- flashing to show a minimum alarm and + to show a maximum
alarm.
To cancel the alarm memory signal, press any key.
It must be remembered that if an output function is desired (or
the buzzer) with an alarm memory (=ALL or =-ALL) it is
necessary to set the parameter “tAL” = yES.
4.12 - DIGITAL INPUT
All the parameters concerning the digital input functions are
contained in the group “]din”.
The digital input present on the instrument accepts contacts
free of voltage, the function carried out is defined by the
parameter “diF” and the action can be delayed for the time set
in parameter “did”.
The parameter “diF” can be configured for the following
functions:
=0- Digital input not active
= 1 - defrosting commencement command with contact
normally open: on closing the input (and after the “did” time) a
defrosting cycle is activated.
= 2 - defrosting end command with contact normally open: on
closing the input (and after the “did” time) a defrosting cycle is
ended if in progress or defrosting is inhibited.
= 3 - continuous cycle activation command with contact
normally open: on closing the input (and after the “did” time) a
continuous cycle is started up as described in the paragraph on
the continuous cycle function.
= 4 - External alarm signal with contact normally open: on
closing the input (and after the “did” time) the alarm is activated
and the instrument visualises AL and the variable set in
parameter “diSP” alternately on the display.
= 5 -Cell door opening with light on with contact normally open:
on closing the input (and after the “did” time) the light is switch
on and the instrument visualises AP and the variable set in
parameter “diSP” alternately on the display. With this function
mode, the action of the digital input also activates the time that
can be set in parameter "oAd" after which the alarm is activated
to signal that the door has been left open. At the deactivation of
digital input the light is switch off.

OSAKA –OPERATING INSTRUCTIONS –COMPACT –v.2 –PAG. 8
= 6 -Cell door opening with light on and fan block with contact
normally open: on closing the input (and after the “did” time) the
the light is switch on, the fans are stopped and the instrument
visualises AP and the variable set in parameter “diSP”
alternately on the display. With this function mode, the action of
the digital input also activates the time that can be set in
parameter "oAd" after which the alarm is activated to signal that
the door has been left open. At the deactivation of digital input
the light is switch off. At the alarm activation the fan will be
reactivated even if the digital input is active.
= 7 - Cell door opening with light on, compressor block and fan
block with contact normally open: similar to “diF” = 6 but with
fan and compressor block.
= 8 - Remote control of auxiliary output AUX with contact
normally open: on closing the input (and after the “did” time)
the auxiliary output is activated as described in the "FOA" = 2
function mode of the auxiliary output.
= 9 - Selecting the active set point with contact normally open:
on closing the input (and after the “did” time) the temperature
regulation set point “SP 2” is activated. When instead the input
is open the set point “SP 1” is active (see selecting active set
point)
= 10 - Signalling of external alarm with disablement of all the
control outputs with contact normally open: on closing the input
(and after the “did” time) all the control outputs are disabled,
the alarm is activated and the instrument visualises AL and the
variable set in parameter “diSP” alternately on the display.
= 11 - Switching on/switching off (Stand-by) of instrument with
contact normally open: on closing the input (and after the “did”
time) the instrument is switched on while it is placed in Stand-
by when opened.
= -1, -2, -3 .....-11 - Similar to the previous but with function
logic reversed (contact normally closed)
4.13 - AUXILIARY OUTPUT
All the parameters concerning the auxiliary output functions are
contained in the group “]AuS”.
The auxiliary outpurt can be configured to operate on any of the
outputs by programming the parameter of the desired output =
AuS.
The function carried out is defined by the parameter “FOA”
and the function is conditioned by the time set in parameter
“tuA”.
The parameter “FOA” can be configured for the following
functions:
= 0 - Auxiliary output not active
= 1 - Regulation output delayed with contact normally open: the
auxiliary output is activated with delay that can be set on the
parameter "tuA" compared to the output configured as Out. The
output is then turned off at the same time as the OUT output is
disabled. This function mode can be used as a command for a
second compressor or for all other working utilities according to
the same OUT output conditions, but which must be delayed
after the start up of the compressor to avoid excess electricity
absorption.
= 2 - Activation by front key (U or DOWN/AUX) or by digital
input with contact normally open: the output is activated by
pressing the keys U or DOWN/AUX suitably configured (“USrb”
or “Fbd” = 1) or via activation of the digital input if suitably
configured (“diF”=8). These commands have a bi-stable
function, Which means that when first pressed, the output key
is activated while the second is disabled. In this mode, the AUX
output can be turned off automatically after a certain time that
can be set on the parameter "tuA". With "tuA" = OFF the output
is activated and deactivated only manually, using the front key
(U or DOWN/AUX) or via the digital input. Differently, the
output, once activated, is turned off automatically after the set
time. This function can be used, for example, as a cell light
command, for non-misting resistance or other utilities .
4.14 - FUNCTIONING OF KEYS “U” AND “DOWN/AUX”
Two of the instrument keys, in addition to their normal
functions, can be configured to operate other commands.
The U key function can be defined by the parameter “USrb”
while the DOWN/AUX key function can be defined by the
parameter “Fbd” both contained in the group “]PAn”.
Both the parameters have the same possibilities and can be
configured for the following functions:
=0- The key carries out no function.
= 1 - Pressing the key for at least 1 second, it is possible to
enable/disable the auxiliary output if configured (“FOA”=2).
= 2 - Pressing the key for at least 1 second, it is possible to
select one of the 2 memorised set point in rotation. Once
selection has been made, the display will flash the active set
point code for about 1 sec. (SP 1or SP 2).
4.15 - PARAMETERS CONFIGURATION BY “KEY USB”
The instrument is equipped with a connector that allows the
transfer from and toward the instrument of the functioning
parameters through the device OSAKA KEY USB with 5 poles
connector.
This device it’s mainly useable for the serial programming of
the instruments which need to have the same parameters
configuration or to keep a copy of the programming of an
instrument and allow its rapid retransmission.
To use the device KEY USB it’s necessary that the device or
instrument are being supplied.

To transfer the configuration of an instrument into the device
(UPLOAD) it is necessary to proceed in the following way:
1) position both dip switch of KEY USB in the OFF mode.
2) connect the device to the instrument COMPACT plugging
the special connector.
3) verify that the instrument or the device are supplied
4) observe the indication led on the device KEY USB: if it
results green this means that a configuration is already loaded
on the device while if it results green blinking or red blinking
this means that it has not been loaded any valid configuration
on the device .
5) press the button placed on the device.
6) observe the indication led : after having pressed the button,
the led becomes red and therefore, at the end of the data
transfer, it becomes green.
7) now it is possible to disconnect the device.
To transfer the configuration loaded on the device onto an
instrument of the same family (DOWNLOAD), it is necessary to
proceed in the following way:
1) position both dip switch of KEY USB in the ON mode.
2) connect the device to an instrument COMPACT having the
same features of the one from which has been downloaded the
desired configuration, plugging the special connector.

OSAKA –OPERATING INSTRUCTIONS –COMPACT –v.2 –PAG. 9
3) verify that the instrument or the device are supplied
4) observe the indication led on the device KEY USB: it has to
result green, because if the led results green blinking or red
blinking, this means that on the device it has not been
downloaded any valid configuration and therefore it’s useless to
continue.
5) if the les results green, press the button placed on the
device.
6) observe the indication led : after having pressed the button,
the led becomes red and therefore, at the end of the data
transfer, it becomes green.
7) now it is possible to disconnect the device.
For additional info, please have a look at the KEY USB
instruction manual.
