2.1 Mounting requirements
This instrument is intended for permanent installation, for
indoor use only, in an electrical panel which encloses the
rear housing, exposed terminals and wiring on the back.
Select a mounting location having the following characteristics:
1. it should be easily accessible;
2. there is minimum vibrations and no impact;
3. there are no corrosive gases;
4. there are no water or other fluid (i.e. condensation);
5. the ambient temperature is in accordance with the
operative temperature (0... 50°C);
6. the relative humidity is in accordance with the instrument
specifications (20... 85%);
The instrument can be mounted on panel with a maximum
thickness of 15 mm.
When the maximum front protection (IP65) is desired, the
optional gasket must be monted.
2.2 General notes about wiring
1. Do not run input wires together with power cables.
2. External components (like zener barriers, etc.) connected
between sensor and input terminals may cause errors in
measurement due to excessive and/or not balanced line
resistance or possible leakage currents.
3. When a shielded cable is used, it should be connected at
one point only.
4. Pay attention to the line resistance; a high line resistance
may cause measurement errors.

4. CONFIGURATION PROCEDURE
4.1 Introduction
When the instrument is powered, it starts immediately to work
according to the parameters values loaded in its memory.
The instrument behaviour and its performance are governed
by the value of the stored parameters.
At the first start up the instrument will use a “default”
parameter set (factory parameter set); this set is a generic
one (e.g. a TC J input is programmed).
We recommend to modify the parameter settings to suit your
application (e.g.: input type, Control strategy, alarms, etc.)
To change these parameters you need to enter the
“Configuration mode”.
4.2 Instrument behaviour at Power ON
At power ON the instrument can start in one of the following
mode depending on its configuration:
Auto mode without program functions
–The upper display will show the measured value;
–The lower display will show the Set point value;
–The decimal figure of the less significant digit of the lower
display is OFF;
–The instrument is performing the standard closed loop
control.
Manual mode (OPLO)
–The upper display will show the measured value;
–The lower display will show alternately the power output
and the message <<OPLO>> and the MAN LED will lite;
–The instrument does not perform Automatic control;
–The control output is equal to 0% and can be manually
modified by and buttons.
Stand by mode (St.bY)
–The upper display will show the measured value;
–The lower display will show alternately the set point value
and the message <<St.bY>> or <<od>>;
–The instrument does not perform any control (the control
outputs are OFF);
–The instrument is working as an indicator.
Auto mode with automatic program start up
–The upper display will show the measured value
–The lower display will show one of the following information;
• The operative set point (when it is performing a ramp)
• The time of the segment in progress (when it is perfor-
ming a soak);
• The set point value alternate with the message <St.bY>;
–In all cases, the decimal figure of the less significant digit
of the lower display is lit.
We define all the above described conditions as “Standard
Display”.
4.3 How to enter the “Configuration modes”
Note: The Kube series is equipped with two different
“configuration” methods:
A) The “code” configuration method;
B) The “complete” configuration method.
The “code” configuration method is really fast but covers only
the most common configurations.
The “complete” configuration method allows to take
advantage of all instrument features and capabilities but
requires more time and more skills.
Note that you can take advantage by both methods because
if you use the code configuration and then you enter in the
complete configuration, all selections made by code are still valid.
In both cases the instrument have one complete parameter set.
We call this set “configuration parameter set” (or
“configuration parameters”).
When code configuration method is used all the parameters
not modified by the code will maintain their default values.
In both cases the access to the configuration parameters is
protected by a password (a specific password for each method).
Note: The instrument will show only the parameters consis-
tent with the specific hardware and in accordance with
the value assigned to the previous parameters
(e.g.: if you set an output as “not used” the instrument
will mask all other parameters related to this output).
4.3.1 “Code” configuration procedure
The controller configuration (Input type, Control mode, etc.)
can be made entering two 4-digit codes.
Before to enter into code configuration we suggest you to
prepare the two codes according to the following tables.
to enter into code configuration proceed as follows:
1. Push the button for more than 5 seconds.
The upper display will show PASS while the lower display
will show 0;
2. Using and buttons set the password programmed
in [117] PAS4 parameter. The factory default password
for code configuration is equal to 300;

Ascon Tecnologic - KM series - ENGINEERING MANUAL -Vr.0.0 PAG. 6
3. Push the button;
If the password is correct the instrument will show one of
the following conditions:
• If no code is present, the display shows codE on the
upper display and oFF on the lower display.
• Push the button.
The upper display will show cod1 flashing while the
lower display will show 0000. If a previous code was
stored, the upper display shows cod1 flashing while the
lower display shows the stored code.

4.3.2 Complete configuration procedure.
The configuration parameters are collected in various
groups. Every group defines all parameters related with a
specific function (e.g.: control, alarms, output functions).
1. Push the button for more than 5 seconds.
The upper display will show PASS while the lower display
will show 0.
2. Using and buttons set the programmed password.
Notes: 1. The factory default password for configuration
parameters is equal to 30.
2. During parameter modification the instrument
continue to perform the control.
In certain conditions, when a configuration chan-
ge can produce a heavy bump to the process, it is
advisable to temporarily stop the controller from
controlling during the programming procedure
(control output will be OFF).
A password equal to 2000 + the programmed
value (e.g. 2000 + 30 = 2030).
The control will restart automatically when the
configuration procedure will be manually closed.
3. Push the button
If the password is correct the display will show the acronym
of the first parameter group preceded by the symbol:
.
In other words the upper display will show:
(group of the Input parameters).
The instrument is in configuration mode.
4.4 How to exit from the “Configuration
mode”
Push button for more than 5 seconds, the instrument will
come back to the “standard display”.
4.5 Keyboard functions during parameter
changing
A short press allows to exit from the current parameter
group and select a new parameter group.
A long press allows you to close the configuration
parameter procedure (the instrument will come back
to the “standard display”).
When the upper display is showing a group and the
lower display is blank, this key allows to enter in the
selected group.
When the upper display is showing a parameter and
the lower display is showing its value, this key allows
to store the selected value for the current parameter
and access the next parameter within the same group.
Allows to increase the value of the selected parameter.
Allows to decrease the value of the selected parameter.
+ These wto keys allow to return to the previous
group. Proceed as follows:
Push the button and maintaining the pressure,
then push the button; release both the buttons.
Note: The group selection is cyclic as well as the selection
of the parameters in a group.
4.6 Factory reset - default parameters
loading procedure
Sometime, e.g. when you re-configure an instrument
previously used for other works or from other people or when
you have made too many errors during configuration and
you decided to re-configure the instrument, it is possible to
restore the factory configuration.
This action allows to put the instrument in a defined
condition (the same it was at the first power ON).
The default data are those typical values loaded in the
instrument prior to ship it from factory.
To load the factory default parameter set, proceed as follows:
1. Press the button for more than 5 seconds;
2. The upper display will show PASS while the lower display
shows 0;
3. Using and buttons set the value -481;
4. Push button;
5. The instrument will turn OFF all LEDs for a few seconds,
than the upper display will show dFLt (default) and then
all LEDs are turned ON for 2 seconds. At this point the
instrument restarts as for a new power ON.
The procedure is complete.
Note: The complete list of the default parameters is available
in Appendix A.
4.7 All configuration parameters
In the following pages we will describe all the parameters of
the instrument. However, the instrument will only show the
parameters applicable to its hardware options in accordance
with the specific instrument configuration (i.e. setting AL1t
[Alarm 1 type] to nonE [not used], all parameters related to
alarm 1 will be skipped).

the maximum displayed value become 999.9°C

Ascon Tecnologic - KM series - ENGINEERING MANUAL -Vr.0.0 PAG. 8
or 999.9°F.
2. Every change of the SEnS parameter setting
will force the [2] dP = 0 and it will change all
parameters related with dP (e.g. set points,
proportional band, etc.).
[2] dP - Decimal point position
Available: Always.
Range: When [1] SenS = Linear input: 0... 3.
When [1] SenS different from linear input: 0 or 1.
Note: Every change of the dP parameter setting will produce
a change of the parameters related with it (e.g.: set
points, proportional band, etc.).
[3] SSc - Initial scale read-out for linear inputs
Available: when a linear input is selected by [1] SenS.
Range: -1999... 9999.
Notes: 1. SSc allows the scaling of the analogue input to
set the minimum displayed/measured value.
The instrument will show a measured value up
to 5% less then SSc value and than it will show
an underrange error.
2. It is possible to set a initial scale read-out
higher then the full scale read-out in order to
obtain a reverse read-out scaling
E.g.:
0 mA = 0 mBar and 20 mA = -1000 mBar
(vacuum).
[4] FSc - Full scale read-out for linear input
Available: When a linear input is selected by [1] SenS.
Range: -1999... 9999
Notes: 1. Fsc allows the scaling of the analogue input to
set the maximum displayed/measured value.
The instrument will show a measured value up
to 5% higher than [4] FSc value and then it will
show an overrange error.
2. It is possible to set a full scale read-out lower
than the initial scale read-out in order to obtain
a reverse read-out scaling.
E.g.:
0 mA = 0 mBar and 20 mA = -1000 mBar
(vacuum).

Note: This is a first order digital filter applied on the
measured value. For this reason it will affect the
measured value but also the control action and the
alarms behaviour.
[7] inE - Selection of the Sensor Out of Range type that
will enable the safety output value
Available: Always
Range: our = When an overrange or an underrange is
detected, the power output will be forced to
the value of [8] oPE parameter.
or = When an overrange is detected, the power
output will be forced to the value of [8] oPE
parameter.
ur = When an underrange is detected, the po-
wer output will be forced to the value of [8]
oPE parameter.
[8] oPE - Safety output value
Available: Always
Range: -100... 100 % (of the output).
Notes: 1. When the instrument is programmed with one
control action only (heat or cool), setting a
value outside of the available output range, the
instrument will use Zero.
E.g. when heat action only has been
programmed, and oPE is equal to -50%
(cooling) the instrument will use the zero value.
2. When ON/OFF control is programmed and an
out of range is detected, the instrument will
perform the safety output value using a fixed
cycle time equal to 20 seconds.

Notes: 1. When [10] diF1 or [11] diF2 (e.g. diF1) are
equal to 6 the instrument operates as follows:
• When the contact is open, the control action
is an heating action and the active set point
is SP.
• When the contact is closed, the control
action is a cooling action and the active set
point is SP2.
2. When [10] diF1 is equal to 20, [11] diF2 setting
is forced to 20 and diF2 cannot perform another
function.
3. When [10] diF1 and [11] diF2 are equal to 20,
the set point selection will be in accordance
with the following table
Dig In1 Dig. In2 Operative set point
Off Off Set point 1
On Off Set point 2
Off On Set point 3
On On Set point 4
4. When [10] diF1 is equal to 21, [11] diF2 setting
is forced to up.du (21 value) and cannot perform
another function.
5. When a “Sequential set point selection” is used
(diF1 or diF2 = 18), every closure of of the logic
input increase the value of SPAT (active set
point) of one step.
The selection is cyclic -> SP1 -> SP2 -> SP3 -> SP4

[26] Ab1 – Alarm 1 function
Available: When [25] AL1t is different from “nonE”
Range: 0... 15 with the following rule:
+1 = Not active at power up.
+2 = Latched alarm (manual reset)
+4 = Acknowledgeable alarm
+8 =
Relative alarm not active at set point change
Example: setting Ab1 equal to 5 (1+4) the alarm 1 will be
“not active at power up” and “Acknowledgeable”.
Notes: 1. The “not active at power up” selection allows
you to inhibit the alarm function at instrument
power up or when the instrument detects a
transfer from:
• Manual mode (oplo) to auto mode
• Stand-by mode to auto mode.
The alarm will be automatically enabled when
the measured value reaches, for the first time,
the alarm threshold plus or minus the hysteresis
(in other words, when the initial alarm condition
disappears).
2. A “Latched alarm” (manual reset) is an alarm
that will remain active even if the conditions that
generated the alarm no longer persist. Alarm
reset can be done only by an external command
(button, digital inputs or serial link).
3. An “Acknowledgeable” alarm is an alarm that can
be reset even if the conditions that generated
the alarm are still present. Alarm acknowledge
can be done only by an external command (
button, digital inputs or serial link).
A “relative alarm not active at set point change”
is an alarm that masks the alarm condition after
a set point change until process variable reaches
the alarm threshold plus or minus hysteresis.

Available: When [25] AL1t is different from “nonE” or [25]
AL1t is different from “SE.br”.
Range: 1... 9999 engineering units
Notes: 1. The hysteresis value is the difference between
the Alarm threshold value and the point the
Alarm automatically resets.
2. When the alarm threshold plus or minus the
hysteresis is out of input range, the instrument
will not be able to reset the alarm.
Example: Input range 0... 1000 (mBar).
–set point equal to 900 (mBar);
–deviation low alarm equal to 50 (mBar);
–Hysteresis equal to 160 (mBar)
the theoretical reset point is 900 - 50 + 160 = 1010 (mBar)
but this value is out of range.
The reset can be made only by turning the instrument
OFF, removing the condition that generate the alarm and
than turn the instrument ON again.
–All band alarms use the same hysteresis value for both
thresholds;
–When the hysteresis of a band alarm is bigger than the
programmed band, the instrument will not be able to reset
the alarm.
Example: Input range 0... 500 (°C).

)LbA group - Loop break alarm
General note about LBA alarm.
The LBA operate as follows:
When you apply 100% of the power output to a process,
the process variable, after a time due to the process inertia,
begins to change in a known direction (increases for an
heating action or decreases for a cooling action).
Example: if I apply 100% of the power output to a furnace,
the temperature must go up unless one of the component in
the loop is faulty (heater, sensor, power supply, fuse, etc...)
The same philosophy can be applied to the minimum power.
In our example, when I turn OFF the power to a furnaces,
the temperature must go down, if not the SSR is in short
circuit, the valve is jammed, etc..
LBA function is automatically enabled when the PID requires
the maximum or the minimum power.
When the process response is slower than the programmed
limit the instrument generates an alarm.
Notes: 1. When the instrument is in manual mode, the
LBA function is disabled.
2. When LBA alarm is ON the instrument continue
to perform the standard control. If the process
response come back into the programmed limit,
the instrument reset automatically the LBA
alarm.
3. This function is available only when the
programmed control algorithm is equal to PID
(Cont = PID).

LBA application example:
LbAt (LBA time) = 120 seconds (2 minutes)
LbAS (delta LBA) = 5°C
The machine has been designed in order to reach 200°C in
20 minutes (20°C/min).
When the PID demand 100 % power, the instrument starts
the time count.
During time count if the measured value increases more
than 5°C, the instrument restarts the time count. Otherwise

[54] Auto - Auto tune selection
Ascon Tecnologic has developed three auto-tune algorithms:
–Oscillating auto-tune;
–Fast auto-tune;
–EvoTune.
1. The oscillating auto-tune is the usual auto-tune and:
• It is more accurate
• Can start even if PV is close to the set point.
• Can be used even if the set point is close to the
ambient temperature.
2. The fast type is suitable when:
• The process is very slow and you want to be opera-
tive in a short time.
• When an overshoot is not acceptable.
• In multi loop machinery where the fast method
reduces the calculation error due to the effect of the
other loops.
3. The EvoTune type is suitable when:
• You have no information about your process.
• You can not be sure about the end user skills.
• You desire an auto tune calculation independently
from the starting conditions (e.g. set point change
during tune execution, etc).
Note: Fast auto-tune can start only when the measured
value (PV) is lower than (SP + 1/2SP).
Available: When [53] cont = PID
Range: -4... 8 where:
-4 = Oscillating auto-tune with automatic restart
at all set point change.
-3 = Oscillating auto-tune with manual start.
-2 = Oscillating auto-tune with automatic start at
the first power up only.
-1 = Oscillating auto-tune with automatic restart
at every power up
0 = Not used
1 = Fast auto tuning with automatic restart at
every power up
2 = Fast auto-tune with automatic start at the
first power up only.
3 = FAST auto-tune with manual start
4 = FAST auto-tune with automatic restart at all
set point change.
5 = EvoTune with automatic restart at every
power up
6 = EvoTune with automatic start at the first
power up only.
7 = EvoTune with manual start
8 = EvoTune with automatic restart at all set
point change.
Note: All auto-tunes are inhibited during program execution.
[55] Aut.r - Manual start of the auto-tune
Available: When [53] cont = PID
Range: oFF =
The instrument is not performing the auto-tune
on = The instrument is performing the auto-tune
[56] SELF - Self-tune enable
The self-tuning is an adaptive algorithm able to obtimize
continuously the PID parameter value.
This algorithm is specifically designed for all process
subjected to big load variation able to change heavily the
process response.
Available: When [53] cont = PID
Range: YES = self-tune active;
on = self-tune not active.
[57] HSEt - Hysteresis of the ON/OFF control
Available: When [53] cont is different from PID.
Range: 0... 9999 engineering units.
[58] cPdt - Time for compressor protection

Range: 1... 9999 engineering units.
Note: Auto-tune functions calculate this value.
[60] ti - Integral time
Available: When [53] cont = PID and [56] SELF = no
Range: OFF = Integral action excluded

Note: Auto-tune functions calculate this value.
[62] Fuoc - Fuzzy overshoot control
This parameter reduces the overshoot usually present at
instrument start up or after a set point change and it will be
active only in this two cases.
Setting a value between 0.00 and 1.00 it is possible to slow
down the instrument action during set point approach.
Setting Fuoc = 1 this function is disabled.

Range: 0... 2.00.
Note: Fast auto-tune calculates the Fuoc parameter while
the oscillating one sets it equal to 0.5.
[63] tcH - Cycle time of the heating output
Available: When at least one output is programmed in order
to be the heating output (H.rEG),
[53] cont = PID and [56] SELF = no
Range: 1.0... 130.0 seconds
[64] rcG - Power ratio between heating and cooling ac-
tion (relative cooling gain)
The instrument uses the same PID parameter set for heat
and for cool action but the efficiency of the two actions are
usually different.
This parameter allows to define the ratio between the efficien-
cy of the heating system and the efficiency of the cooling one.
An example will help us to explain you the philosophy.
Consider one loop of a plastic extruder.
The working temperature is equal to 250°C.
When you want to increase the temperature from 250 to
270°C (DT = 20°C) using 100% of the heating power (resis-
tor), you will need 60 seconds.
On the contrary, when you want to decrease the temperature
from 250 to 230°C (DT = 20°C) using 100% of the cooling
power (fan), you will need 20 seconds only.
In our example the ratio is equal to 60/20 = 3 ([64] rcG = 3)
and it say that the efficiency of the cooling system is 3 time
more efficient of the heating one.
Available: When two control action are programmed
(H.rEG and c.rEG) and
[53] cont = PID and
[56] SELF = no
Range: 0.01... 99.99
Note: auto-tune functions calculate this value.
[65] tcc - Cycle time of the cooling output
Available: When at least one output is programmed in order
to be the cooling output (c.rEG), [53] cont = PID
and [56] SELF = no
tcc allows to drastically reduce the undershoot due to a
hot restart. When your process is steady, the instrument
operates with a steady power output (e.g.: 30%).
If a short power down occurs, the process restarts with a
process variable close to the set point while the instrument
starts with an integral action equal to zero.
Setting a manual reset equal to the average power output
(in our example 30 %) the instrument will start with a power
output equal to the value it will use at steady state (instead
of zero) and the undershoot will become very little (in theory
equal to zero).
Available: When [53] cont = PID.
Range: -100.0... +100.0%
[67] od – Delay at power up
Available: When at least one output is programmed as
control output.
Range: • oFF: Function not used;
• 0.01...99.59hh.mm.
Notes: 1. This parameter defines the time during which
(after a power up) the instrument remains in
stand by mode before to start all other function
(control, alarms, program, etc.).
2. When a program with automatic start at power
up and od function are programmed, the
instrument performs od function before to start
the program execution.
3. When an auto-tune with automatic start at
power up and od function are programmed, the
autotune will start at the end of od delay.
[68] St.P - Maximum power output used during soft start
Available: When at list one output is programmed as control
output.
Range: -100... +100%.
Notes: 1. When St.P parameter have a positive value, the
limit will be applied to the heating output(s) only.
2. When St.P parameter have a negative value,
the limit will be applied to the cooling output(s)
only.
3. When a program with automatic start at power
up and soft start function are programmed, the
instrument performs the soft start and than the
program function.
4. The auto-tune function will be performed after
soft start function.
5. The Soft start function is available also when
ON/OFF contro l is used.
[69] SSt - Soft start time
Available: When at list one output is programmed as control
output.
Range: oFF = Function not used;
0.01... 7.59 hh.mm;
inF = soft start always active.

Ascon Tecnologic - KM series - ENGINEERING MANUAL -Vr.0.0 PAG. 17
[70] SS.tH – Threshold for soft start disabling
Available: When at list one output is programmed as control
output.
Range: -1999... 9999 engineering units.
Notes: 1. When the power limiter have a positive value
(the limit is applied to the heating action) the
soft start function will be aborted when the
measured value is greater or equal to SS.tH
parameter.
2. When the power limiter have a negative value
(the limit is applied to the cooling action) the
soft start function will be aborted when the
measured value is lower or equal to SS.tH
parameter.
)SP Group - Set point parameters
The SP group will be available only when at least one output
is programmed as control output (H.rEG or C.rEG).
[71] nSP – Number of used set points
Available: When at least one output is programmed as
control output.
Range: 1... 4.
Note: When you change the value of this parameter, the
instrument operates as follows:
• [78] A.SP parameter will be forced to SP.
• The instrument verifies that all used set point are
within the limits programmed by [72] SPLL end [73]
SPHL. If an SP is out of this range, the instrument
forces it to the maximum acceptable value
[72] SPLL - Minimum set point value
Available: When at least one output is programmed as
control output.
Range: From -1999 to [73] SPHL engineering units
Notes: 1. When you change the [72] SPLL value, the
instrument checks all local set points (SP, SP2,
SP3 and SP4 parameters) and all set points
of the program ([92] Pr.S1, [97] Pr.S2, [102]
Pr.S3, [107] Pr.S4 parameters). If an SP is
out of this range, the instrument forces it to the
maximum acceptable value
2. A [72] SPLL change produces the following
actions:
• When [79] SP.rt = SP the remote set point will
be forced to be equal to the active set point
• When [79] SP.rt = trim the remote set point
will be forced to zero
• When [79] SP.rt = PErc the remote set point
will be forced to zero
[73] SPHL - Maximum set point value
Available: When at least one output is programmed as
control output.
Range: From [73] SPLL to 9999 engineering units
Note: For other details see [73] SPLL parameter.

trol output and [71] nSP > 3.
Range: From [72] SPLL to [73] SPHL engineering units
[77] SP 4 - Set Point 4
Available: When at least one output is programmed as con-
trol output and [71] nSP =4.
Range: From [72] SPLL to [73] SPHL engineering units
[78] A.SP - Selection of the active Set point
Available: When at least one output is programmed as
control output.
Range: From “SP” to [71] nSP.
Notes: 1. A [78] A.SP change produces the following
actions:
• When [79] SP.rt = SP - the remote set point
will be forced to be equal to the active set point
• When [79] SP.rt = trin - the remote set point
will be forced to zero
• When [79] SP.rt = PErc - the remote set
point will be forced to zero
2. SP2, SP3 and SP4 selection will be shown only
when the relative set point is enabled (see [71]
nSP parameter).
[79] SP.rt – Remote set point type
These instruments will communicate with each other, using
RS 485 serial interface without a PC. An instrument can be
set as a Master while the other are (as usual) Slave units. The
Master unit can send his operative set point to the slave units.
In this way, for example, it is possible to change
simultaneously the set point of 20 instruments by changing
the set point of the master unit (e.g. hot runner application).
SP.rt parameter defines how the slaves units will use the
value coming from serial link.
The [127] tr.SP (Selection of the value to be retransmitted
(Master)) parameter allows to define the value sent by
master unit.
Available: When at least one output is e programmed as
control output and the serial interface is present.
Range: rSP = The value coming from serial link is used
as remote set point (RSP).
trin = The value coming from serial link will be
algebraically added to the local set point
selected by A.SP and the sum becomes
the operative set point
PErc = The value coming from serial will be scaled
on the input range and this value will be
used as remote set point.
Notes: 1. A [79] SPrt change produces the following
actions:
• When [79] SP.rt = rSP - the remote set point
will be forced to be equal to the active set point
• When [79] SP.rt = trin - the remote set point
will be forced to zero
• When [79] SP.rt = PErc - the remote set
point will be forced to zero
Example:
A 6 zone reflow-oven for PCB .

Ascon Tecnologic - KM series - ENGINEERING MANUAL -Vr.0.0 PAG. 18
The master unit sends its set point value to 5 other zones
(slave controllers).
The Slave zones use it as a set point trim.
The first zone is the master zone and it uses a set point
equal to 210°C.
The second zone has a local set point equal to -45°C
The third zone has a local set point equal to -45 (°C)
The fourth zone has a local set point equal to -30
The fifth zone has a local set point equal to +40
The sixth zone has a local set point equal to +50
In this way, the thermal profile will be the following:
–master SP = 210°C
–second zone SP = 210 -45 = 165°C
–third zone SP = 210 -45 = 165°C
–fourth zone SP = 210 - 30 = 180°C
–fifth zone SP = 210 + 40 = 250°C
–sixth zone SP = 210 + 50 = 260°C
Changing the SP of the master unit, all the other slave units
will immediately change their operative set point.
[80] SPLr - Local/remote set point selection
Available: When at list one output is programmed as control
output.
Range: Loc = Local set point selected by [78] A.SP

(ramp down)
Available: When at list one output is e programmed as
control output.
Range: 0.01... 99.99 units per minute

General note about remote set point: when the remote set
point (RSP) with trim action is programmed, the local set
point range becomes the following:
from [72] SPLL+ RSP to [73] SPHL - RSP

Note: This parameter allows to manage timer execution by a
parameter (without digital inputs or button).
)PrG Group - Programmer function parameters
These instruments are able to perform a set point profile
compounded of 4 groups of 2 steps (8 step total).
The first step is a ramp (used to reach the desired set point),
the second is a soak (on the desired set point).
When a RUN command is detected the instrument aligns
the operative set point to the measured value and starts to
execute the first ramp.
In addition, each soak is equipped with a wait band which
suspends the time count when the measured value goes out
of the defined band (guaranteed soak).
Moreover, for each segment it is possible to define the status
of two events. An event can drive an output and make an
action during one or more specific program steps.
Some additional parameters allow to define the time scale,
the automatic RUN conditions and the instrument behaviour
at the end of the program.
Notes: 1. All steps can be modified during program
execution.
2. During program execution the instrument
memorize the segment currently in use and,
by a 30 minutes interval, it memorize also the
elapsed time of the soaks.
If a power down occurs during program
execution, at the next power up the instrument is
able to continue the program execution starting
from the segment in progress at power down
and, if the segment was a soak, it is also capable
to restart from the soak time minus the elapsed
time memorized.
In order to obtain this features, the [122] dSPu
“Status of the instrument at power u” parameter
must be set to “AS.Pr”.
If [122] dSPu value is different from “AS.Pr”, the
memorization function will be inhibited.

[97] Pr.S2 - Set point of the second soak
Available: When [88] Pr.F is different from nonE
Range: From [72] SPLL to [73] SPHL
oFF = Program end.
Note: It is not necessary to configure all steps.
When you use for example 2 groups only, it is
sufficient to set the set point of the third group equal
to OFF. The instrument will mask all the following
parameters of the programmer.
[98] Pr.G2 - Gradient of the second ramp
Available: When [88] Pr.F is different from nonE and [98]
Pr.S2 is different from oFF.
Range: 0.1... 999.9 engineering units per minute;
inF = Step transfer.
[99] Pr.t2 – Time of the second soak
Available: When [88] Pr.F is different from nonE and [97]
Pr.S2 is different from oFF.
Range: 0.00... 99.59 time units.
[100] Pr.b2 - Wait band of the second soak
Available: When [88] Pr.F is different from nonE and [97]
Pr.S2 is different from oFF.
Range: OFF... 9999 engineering units.
Note: For more details see [95]Pr.b1 parameter.
[101] Pr.E2 - Events of the second group
Available: When [88] Pr.F is different from nonE and [97]
Pr.S2 is different from oFF
Range: 00.00... 11.11 where:
0 = Event OFF;
01 = Event ON.
Note: For more details see [96]Pr.E1 parameter.
[102] Pr.S3 - Set point of the third soak
Available: When [88] Pr.F is different from nonE and [97]
Pr.S2 is different from oFF
Range: from [72] SPLL to [73] SPHL;
oFF = Program end.
Note: For more details see [97]Pr.S2 parameter.
[103] Pr.G3 - Gradient of the third ramp
Available: When [88] Pr.F is different from nonE, [97] Pr.S2
is different from oFF and [102] Pr.S3 is different
from OFF.
Range: 0.1... 999.9 engineering units per minute;
inF = Step transfer.
