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).
WARNING! Before connecting the output actuators,
we recommend to configure the parameters 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 KX Line 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 modifies
only the most common configuration parameters.
The “complete” configuration method allows to take
advantage of all instrument features, giving more capabilities
it requires more actions and time.
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 tables that follow.
Notes: 1. During the Code configuration procedure there is
no timeout.
2. To leave, at any time, the Configuration session
without saving the settings made, press the
button.
To enter into code configuration proceed as follows:
1. Push the button for more than 3 seconds.
The upper display will show PASS while the lower display
will show 0;
2. Using and buttons set the password programmed
in parameter [121] PAS4. The factory default password
for Code configuration is 300;
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 to continue.
The upper display will flash cod1 while the lower display
shows 0000.
• If a previous code was stored, the upper display will
flash cod1 while the lower display shows the value of
cod1 stored in memory.

8. Push the button to save the configuration code and
exit the Code configuration procedure.
Note: After using the “Code configuration” method, it will
always be possible to modify the parameters using the
“Complete configuration” method. If the value of a
parameter among those included in the configuration
codes (cod1 - cod2) gets modified, the instrument
will acquire the change while maintaining all the other
parameters.
WARNING! After a parameter change made as described
in the previous “Note”, when retrieving the
configuration codes (cod1 - cod2), the lower
display will show “oFF” to alert the operator that
one of the parameters has been changed.

Ascon Tecnologic - KX Line - ENGINEERING MANUAL -Vr.4.0 PAG. 7
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: pinp
(group of the Input parameters).
The instrument is in configuration mode.
4.3.3 How to exit the “Configuration mode”
Push button for more than 5 seconds, the instrument will
come back to the “standard display”.
4.4 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 two 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.
4.5 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,
then 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.
4.6 CONFIGURING ALL THE 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).

Notes: 1. When a TC input is selected and a decimal figure
is programmed (see the next parameter) the max.
displayed value becomes 999.9°C 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).
[5] unit - Engineering unit
Available: When a temperature sensor is selected by [1]
SenS parameter.
Range: °c = Centigrade
°F = Fahrenheit
[6] FiL - Digital filter on the measured value
Available: Always
Range: oFF (No filter) 0.1 to 20.0 s
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.
[9] io4.F - I/O4 function selection
Available: Always
Range: on = The out 4 will be always ON (used as a
transmitter power supply);
out4 = used as digital output 4;
dG2.c = Digital input 2 for contact closure;
dG2.U= Digital input 2 driven by 12... 24 VDC.
Notes: 1. Setting [9] io4.F = dG2.C o dG2V, the [24] O4F
parameter becomes not visible while [11] diF2
parameter will become visible.
2. Setting [9] io4F = on the [24] O4F parameter and
the [11]diF2 parameter will NOT be visible.
3. Setting [9] io4F different from dG2.c or dG2.U,
the instrument will force [12] diF2 parameter
equal to nonE
If [11] diF1 was equal to (SP4 or UPDN) it will be
forced to nonE.
4. The transfer from [9] io4F = on to [9] io4F = Out
4 will make the [24] O4F parameter visible equal
to nonE.

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 = 20, [11] diF2 setting is forced to
20 and diF2 cannot perform another function.
3. When [10] diF1 = 20 and [11] diF2 = 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:
SP -> SP2 -> SP3 -> SP4.

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.

Ascon Tecnologic - KX Line - ENGINEERING MANUAL -Vr.4.0 PAG. 13
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
then 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).
–Set point equal to 250 (°C);
–Relative band alarm;
–Low threshold equal to 10 (°C);
–High threshold equal to 10 (°C);
–Hysteresis equal to 25 (°C).

]LbA group - Loop break alarm
General note about LBA alarm
The LBA operate as follows: applying the 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 (in-
creases 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 furnace, 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 continues
to perform the standard control. If the process
response comes back into the programmed limit,
the instrument automatically resets the LBA alarm.
3. This function is available only when the programmed
control algorithm is equal to PID (Cont = PID).
[51] LbAt - LBA time
Available: When [55] Cont = PID
Range: • oFF = LBA not used;
• 1... 9999 seconds.

• 1... 9999 engineering units.
[53] LbAS - Delta measure used by loop break
alarm (loop break alarm step)
Available: when [51] LbAt is different from oFF
Range: From 1 to 9999 engineering units.

Ascon Tecnologic - KX Line - ENGINEERING MANUAL -Vr.4.0 PAG. 15
[54] LbcA - Condition for LBA enabling
Available: when [51] LbAt is different from oFF
Range: uP = Enabled when the PID requires the maxi-
mum power only.
dn = Enabled when the PID requires the mini-
mum power only
both = Enabled in both condition (when the PID re-
quires the maximum or the minimum power).
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 demands 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
if the measured value does not reach the programmed delta
(5°C in 2 minutes) the instrument will generate the alarm.

[56] 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 [55] 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.

Range: oFF = The instrument is not performing the auto-tune;
on = The instrument is performing the auto-tune.
[58] SELF - Self-tune enable
The self-tuning is an adaptive algorithm able to optimize
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.

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.

Range: 0... 2.00.
Note: Fast auto-tune calculates the Fuoc parameter while
the oscillating one sets it equal to 0.5.
[65] tcH - Cycle time of the heating output
Available: When at least one output is programmed in order
to be the heating output (H.rEG),
[55] cont = PID and [58] SELF = no.
Range: 1.0... 130.0 seconds
[66] rcG - Power ratio between heating and cooling
action (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 tem-
perature 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 ([66] 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
[55] cont = PID and
[58] SELF = no
Range: 0.01... 99.99
Note: auto-tune functions calculate this value.
[67] tcc - Cycle time of the cooling output
Available: When at least one output is programmed in order
to be the cooling output (c.rEG), [55] cont = PID
and [58] SELF = no
Range: 1.0... 130.0 seconds.
[68] rS - Manual reset (integral pre-load)
It 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 [55] cont = PID.
Range: -100.0... +100.0%.
[69] Str.t - Servomotor stroke time (KX3 servo only)
Available: When [55] cont = 3Pt.
Range: 5... 1000 seconds;
[70] db.S - Servomotor dead band (KX3 servo only)
Available: When [55] cont = 3Pt.
Range: 0... 100%;
[71] 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.

Ascon Tecnologic - KX Line - ENGINEERING MANUAL -Vr.4.0 PAG. 17
[72] St.P - Max. 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.

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).
[75] 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:
• [82] A.SP parameter will be forced to SP.
• The instrument verifies that all used set point are
within the limits programmed by [76] SPLL end [77]
SPHL. If an SP is out of this range, the instrument
forces it to the maximum acceptable value
[76] SPLL - Minimum set point value
Available: When at least one output is programmed as
control output.
Range: From -1999 to [77] SPHL engineering units
Notes: 1. When you change the [76] SPLL value, the
instrument checks all local set points (SP, SP2,
SP3 and SP4 parameters) and all set points of the
program ([96] Pr.S1, [101] Pr.S2, [106] Pr.S3, [111]
Pr.S4 parameters). If an SP is out of this range, the
instrument forces it to the maximum acceptable value
2. A [76] SPLL change produces the following actions:
• When [83] SP.rt = SP the remote set point will
be forced to be equal to the active set point
• When [83] SP.rt = trim the remote set point
will be forced to zero
• When [83] SP.rt = PErc the remote set point
will be forced to zero
[77] SPHL - Maximum set point value
Available: When at least one output is programmed as
control output.
Range: From [77] SPLL to 9999 engineering units
Note: For other details see [77] SPLL parameter.

Available: When at least one output is programmed as con-
trol output and [75] nSP > 2.
Range: From [76] SPLL to [77] SPHL engineering units.
[80] SP 3 - Set Point 3
Available: When at least one output is programmed as con-
trol output and [75] nSP > 3.

[81] SP 4 - Set Point 4
Available: When at least one output is programmed as con-
trol output and [75] nSP =4.
Range: From [76] SPLL to [77] SPHL engineering units.
[82] A.SP - Selection of the active Set point
Available: When at least one output is programmed as
control output.
Range: From “SP” to [75] nSP.
Notes: 1. A [82] A.SP change produces the following actions:
• When [83] SP.rt = SP - the remote set point
will be forced to be equal to the active set poin;
• When [83] SP.rt = trin - the remote set point
will be forced to zero;
• When [83] 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
[75] nSP parameter).
[83] 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 [132] 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

Ascon Tecnologic - KX Line - ENGINEERING MANUAL -Vr.4.0 PAG. 18
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.
Note: A [83] SPrt change produces the following actions:
• When [83] SP.rt = rSP - the remote set point
will be forced to be equal to the active set point
• When [83] SP.rt = trin - the remote set point
will be forced to zero
• When [83] SP.rt = PErc - the remote set
point will be forced to zero
Example: A 6 zone reflow-oven for PCB.
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.

Available: When at list one output is programmed as control
output.

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:

]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 stores the
segment currently in use and, by a 30 m interval, it
stores 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 [127] dSPu
“Status of the instrument at power u” parameter
must be set to “AS.Pr”.
If [127] dSPu value is different from “AS.Pr”, the
memorization function will be inhibited.

[92] Pr.F = Programmer action at power up
Available: Always.
Range: nonE = Program not used
S.uP.d = Start at power up with a first step in stand by
S.uP.S = Start at power up
u.diG = Start at RUN command detection only
U.dG.d = Start at RUN command detection with a
first step in stand by.
[93] Pr.u - Engineering units of the soaks
Available: When [92] Pr.F is different from nonE:
Range: hh.nn = Hours and minutes;
nn.SS= Minutes and seconds.
Note: During program execution, this parameter can not be
modified.
[94] Pr.E - Instrument behaviour at the End of the
program execution
Available: When [92] Pr.F is different from nonE
Range: cnt = Continue (the instrument will use the set
point of the last soak until a reset command
is detected);
SPAt = Go to the set point selected by [82] A.SP
parameter;
St.bY = Go in stand by mode.
Notes: 1. Setting [95] Pr.E = cnt the instrument operates as
follows: at program end, it will use the set point of
the last soak.
2. When a reset command is detected, it goes to
the set point selected by [82] A.SP parameter.
The transfer will be a step transfer or a ramp ac-
cording to the [85] SP.u (maximum rate of rise for
positive set point change) and [86] SPd (maximum
rate of rise for negative set point change).
3. Setting [94] Pr.E = SPAt the instrument goes
immediately to the set point selected by [82] A.SP
parameter. The transfer will be a step transfer or
a ramp according to the [85] SP.u (maximum rate
of rise for positive set point change) and [86] SPd
(maximum rate of rise for negative set point change).
