1. OUTLINE DIMENSIONS (mm)
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 (from 0 to 50
°C).
6) the relative humidity is in accordance with the
instrument specifications ( 20% to 85 %).
The instrument can be mounted on OMEGA rail in
accordance with EN 50 022 (35 x 7.5 mm or 35 x 15
mm) regulations.
2.2 GENERAL NOTES ABOUT INPUT WIRING
1) Don’t 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

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 performances are
governed by the value of the memorized 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 that you modify the parameter set to
suit your application (e.g. set the right input type,
Control strategy, define an alarm, etc.)
To change these parameters you will need to enter the
“Configuration procedure”.
4.1.1 Access levels to the parameter modifications
and their password
The instrument have one complete parameter set.
We call this set “configuration parameter set” (or
“configuration parameters”).
The access to the configuration parameters is protected
by a programmable password (password level 3).
The configuration parameters are collected in various
groups. Every group defines all parameters related with a
specific function (E.g. control, alarms, output functions).
Note the instrument will show only the parameters
consistent 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 with
this output).
4.2 INSTRUMENT BEHAVIOUR AT POWER UP
At power up the instrument can start in one of the
following mode depending on its configuration:
Auto mode without program functions
- The display will show the measured value
- The decimal figure of the less significant digit is OFF
- The instrument is performing the standard closed loop
control.
Manual mode (OPLO)
- The display will show alternately the measured value
and the message <<OPLO>>.
- 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 display will show alternately the measured 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 display will show one of the following information:
- the measured value
- the operative set point (when it is performing a ramp)
- the time of the segment in progress (when it is
performing a soak).
- the measured value alternate with the message
<<St.bY>>.
- In all cases, the decimal figure of the less significant
digit is lit.
We define all the above described conditions as
“Standard Display”.
4.3.HOW TO ENTER INTO THE CONFIGURATION
MODE
1) Push the P button for more than 3 seconds.
The display will show alternately 0 and << PASS >>.
2) Using and/or buttons set the programmed
password.
NOTES:
a) The factory default password for configuration
parameters is equal to 30.
b) All parameter modification are protected by a time
out. If no button is pressed for more than 10 second
the instrument return automatically back to the
Standard display, the new value of the last selected
parameter is lost and the parameter modification
procedure is closed.
When you desire to remove the time out (e.g. for
the first configuration of an instrument) you can use
a password equal to 1000 plus the programmed
password (e.g. 1000 + 30 [default] = 1030).
It is always possible to end manually the parameter
configuration procedure (see the next paragraph).
c) During parameter modification the instrument
continue to perform the control.
In certain conditions, when a configuration change
can produce a heavy bump to the process, it is
advisable to temporarily stop the controller from
controlling during the programming procedure (its
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 P 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 display will show .
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 FUNCTION DURING PARAMETER
MODIFICATION
A short press allows you 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 display is showing a group, It allows you
to enter in the selected group.
When the display is showing a parameter, it allows
you to memorize the selected value and to go
to the next parameter within the same group.
it allows you to increase the value of the selected
parameter
it allows you to decrease the value of the selected
parameter
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
Some times, 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 you to put the instruent in a defined con-
dition (in the same condition it was at the first power up).
The default data are the typical values loaded in the
instrument prior to shipment from factory.
To load the factory default parameter set, proceed as
follows:
1) Press the P button for more than 5 seconds
2) The display will show alternately “PASS” and “0”.
3) By and button set the value -481.
4) Push P button.
5) The instrument will turn OFF all LEDs then it will show
“dFLt” messages and than it turn ON all LEDs of the
display for 2 seconds and than it will restart as for a
new power up.
The procedure is complete.
Note: the complete list of the default parameter is
available in Appendix A.
4.7.ALLCONFIGURATION 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] equal to <<nonE>> [not used],
all parameters related with the alarm 1 will be skipped).

set points, proportional band, etc.)
[4] SSc – Initial scale read-out for linear inputs
Available: when a linear input is selected by [2] SenS.
Range: -1999 to 9999
Notes:
- It 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.
- 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

Notes about digital inputs
1) When diF1 or diF2 (e.g. diF1) are equal to 5 the
instrument operates as follows:
- when the contact is open, the control action is an
heating action and the active set point is SP1.
- when the contact is closed, the control action is a
cooling action and the active set point is SP2.
2) When diF1 is equal to 18, diF2 setting is forced to 18
and diF2 value and cannot perform another
additional function.
3) When diF1 and diF2 are equal to 18, 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 diF1 is equal to 19, diF2 setting is forced to
up.du and 19 value and cannot perform another
additional function.
5) When a “Sequential set point selection” is used,
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

hysteresis is out of input range, the instrument will not
be able to reset the alarm.
Example: Input range from 0 to 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

The reset can be made only by turning the instrument
OFF, removeing 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.

] 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:
- When the instrument is in manual mode, the LBA
function is disabled.
- 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.
- 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 if the measured value does not
reach the programmed delta (5 °C in 2 minutes) the
instrument will generate the alarm.
] rEG group - Control parameters
The rEG group will be available only when at least
one output is programmed as control output (H.rEG
or C.rEG).
[52] cont - Control type:
Available: when at least one output is programmed as
control output (H.rEG or C.rEG).
Range:
When two control action (heat and cool) are
programmed:
Pid = PID (heat and cool)
nr = Heat/Cool ON/OFF control with neutral
zone
- ON/OFF control with asymmetric hysteresis :
- OFF when PV > SP
- ON when PV < (SP - hysteresis)
- ON/OFF control with symmetric hysteresis :
- OFF when PV > (SP + hysteresis)
- ON when PV < (SP - hysteresis)
[53] Auto – Auto tune selection
SIKA has developed two auto-tune algorithms:
1) Oscillating auto-tune:
2) Fast auto-tune
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 operative
in a short time.
- When an high overshoot is not acceptable.
- In multi loop machinery where the fast method reduces
the calculation error due to the effect of the other loops.
NOTE: fast auto-tune can start only when the measured
value (PV) is lower than (SP + 1/2SP).

[61] 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.

heating output.
It aims to respect the minimum cycle time of a specific
actuator in order to assure a long actuator life.

[64] PrAt - 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
efficiency of the heating system and the efficiency of the
cooling one.
An example will help us tu 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 (delta 20 °C) using 100% of the heating power
(resistor), you will need 60 seconds.
On the contrary, when you want to decrease the
temperature from 250 to 230 °C (delta 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 ([60] PrAt
= 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 [52] cont = PID and [55] SELF =
no
Range: from 0.01 a 99.99
Note: auto-tune functions calculate this value.
[65] c.Act – Cooling output (C.rEG) actuator
Available: When at list one output is e programmed in
order to be the cooling output (c.rEG), [52] cont = PID
and [55] SELF = no
Range:
SSr = Solid state relay output
rELY. = Relay or contactor
SLou = Slow actuator (e.g. compressors)
Note: for more details see [62] h.Act parameter
[66] tcrc - Cycle time of the cooling output
Available: When at least one output is e programmed in
order to be the cooling output (c.rEG), [52] cont = PID
and [55] SELF = no
Range:
when [62] H.Act = SSr

when [62] H.Act = reLY
from 20,0 to 130.0 seconds
when [62] H.Act = SLou
from 40,0 to 130.0 second
Note: auto-tune functions calculate this value.
[67] 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 [52] cont = PID and [55] SELF = no
Range: from -100.0 to 100.0 %
[68] od – Delay at power up
Available: When at list one output is programmed as
control output.
Range:
- oFF : Function not used
- from 0,01 to 99.59 hh.mm
Notes:
- 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.)
- 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.
- When an auto-tune with automatic start at power up
and od function are programmed, the od function will
be aborted and auto-tune will start immediately.
[69] St.P - Maximum power output used during soft
start
Available: When at list one output is programmed as
control output.
Range: from -100 to 100 %
Notes:
- When St.P parameter have a positive value, the limit
will be applied to the heating output(s) only.
- When St.P parameter have a negative value, the limit
will be applied to the cooling output(s) only.
- When a program with automatic start at power up and
soft start function are programmed, the instrument
performs both functions at the same time. In other
words, the program performs the first ramp, while the
requested power is lower than the limit the instrument
operates as usual, when the PID requires more then
the limit the power output will be limited.
- The auto-tune function inhibits the soft start function
- The Soft start function is available also when ON/OFF
contro l is used
[70] SSt - Soft start time
Available: When at list one output is programmed as
control output.
Range:
- oFF : Function not used
- from 0.01 to 7.59 hh.mm
- inF : soft start always active

Range: from -1999 to 9999 engineering units
Note:
- 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.
- 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).
[72] nSP – Number of used set points
Available: When at least one output is programmed as
control output.
Range: from 1 to 4
Note: When you change the value of this parameter, the
instrument operates as follows:
- [79] SPAt parameter will be forced to SP1.
- The instrument verifies that all used set point are within
the limits programmed by [73] SPLL end [74] SPHL.
If an SP is out of this range, the instrument forces it to
the limit more closed to it.
[73] SPLL - Minimum set point value
Available: When at least one output is programmed as
control output.
Range: from -1999 to [74] SPHL engineering units
Notes:
- When you change the [73] SPLL value, the instrument
checks all local set points (SP1, SP2, SP3 and SP4
parameters) and all set points of the program ([94] Pr.S1,
[99] Pr.S2, [104] Pr.S3, [109] Pr.S4 parameters).
If an SP is out of this range, the instrument forces it to
the maximum acceptable value
- A [73] SPLL change produces the following actions
- when [80] SP.rt = SP the remote set point will be
forced to be equal to the active set point
- When [80] SP.rt = trim the remote set point will be
forced to zero
- When [80] SP.rt = PErc the remote set point will be
forced to zero

control output and [72] nSP =4.
Range: from [73] SPLL to [74] SPHL engineering units
[79] SPAt - Selection of the active Set point
Available: When at least one output is programmed as
control output.
Range: from “SP1” to [72] nSP.
Notes:
- A [75] SPAt change produces the following actions
- when [80] SP.rt = SP - the remote set point will be
forced to be equal to the active set point
- When [80] SP.rt = trin - the remote set point will be
forced to zero
- When [80] SP.rt = PErc - the remote set point will
be forced to zero
- SP2, SP3 and SP4 selection will be shown only the
relative set point is enabled (see [75] nSP parameter).
[80] SP.rt – Remote set point type
These instrument 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 [125] 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 SPAt and the sum becomes the
operative set point
PErc = The value coming from serial will be scaled

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
- The instrument can receive the start, hold and reset
commands by U button, by logic inputs and/or by
serial link
- An HOLD command can suspend the time count.
[84] t.F= Independent timer function

[85] tr.u – Engineering unit of the time
Available: when [84] Tr.F is different form nonE
Range:
hh.nn = Hours and minutes
nn.SS = Minutes and seconds
SSS.d = Seconds and tenth of seconds
Note: when the timer is running, you can see the value
of this parameter but you can NOT modify it.
[86] tr.t1 – Time 1
Available: when [84] Tr.F is different form nonE
Range:
- when [85] tr.u = hh.nn from 00.01 to 99.59
- when [85] tr.u = nn.SS from 00.01 to 99.59
- when [85] tr.u = SSS.d from 000.1 to 995.9
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 occures 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 “[120]dSPu -
Status of the instrument at power u” parameter
must be set to “AS.Pr”.
If the “[120]dSPu” parameter is different from
“AS.Pr” The memorization function will be hinibit.
