8.0 MEASUREMENT:
Parameters for this are included in the group “InP”. Inputs accepted are Thermocouples
(J, K, E, S, B, R) mv Signals (0-50) mV, (0-60) mV, (12-60) mV,RTD
Pt100.Recommendation is to switch OFF and ON the instrument when these parameters
are modified, to obtain a correct measurement. This can be through par. “unit”, the unit
of measurement (0C, 0F) and through parameter “dp” decimal point. In case of analog
input signals, the value that instrument must visualize at the start of scale is on par.
“IscL” and the value that instrument must visualize at the end of scale is on par.
(Parameter) “Isch”. Instrument can be re-calibrated according to application needs, by
using par. “oFst” and “rate”. If “rate” = 1.000, then using par “oFst”, it is possible to set
positive or negative offset that is simply added to the value read by the probe.
If the offset set is not to be constant for all the measurements, it is possible to operate
the calibration on any of two points. In this case, in order to decide which values to
program on par. “oFst” and “rate”, the following formulae must be applied:
“rate” = (y2-y1)/(x2-x1)
“oFSt” = y2 - rate*x2
Where, y1 = Measured temperature 1
x1 = temperature displayed by instrument
y2 = Measured temperature 2
x2 = temperature displayed by instrument
The instrument thus visualizes the temperature as:
y = x * “rate” + “oFst”
Where y = displayed value and x = measured value.
8.1 Output in case of measurement error:
In case of measurement error (over range/under range/sensor open), the instrument
supplies the power as programmed on par “oPP”. Incase of PID control, the power
output is as a percentage of cycle time. In case of ON/OFF control, the Cycle time is
automatically considered as 20 s (”e.g. In event of probe error with ON/OFF control and
“oPP = 50” the control output will be activated for 10s and deactivated for 10s till
measurement error remains.)
9.0 Display:
Using par. “dIsP”, located in the group “conF”, it is possible to configure the lower
display to visualize different parameters like the control power (coP), operating set point
(sP). In group “conF”, the par. “LEd” is used to definethe LED shift index functioning for
the three LED’s represented as: ’+’, ‘-’, ‘=’. The lighting up of the ‘=’ LED indicates
that the process value is within the range [sP-LEd] and [sP+LEd].
The lighting ‘-’ LED indicates that the process value is lower than [sP-LEd] and lighting
up of ‘+’ indicates that the process value is higher than [sP+LED]

10.0 ACTIVE SET POINT SELECTION:
For catalog no.: 151A13B1, 151B13B1, 151C13B1, 151D13B1
This instrument allows pre-programming of up to 4 different set points (“sP1”, “sP2”,
“sP3”, “sP4”) and then selection of which one must be active. The maximum number of
set points is determined by Par. “nsP” located in the group of parameters “sP”. The
effective set point can be selected:
- by parameter “EFsP” in the group of parameters “sP”.
- by key “C” if par. “key” = “sPsL”
For catalog no.: 151A12B, 151B12B 151C12B,. 151D12B
This instrument allows pre-programming of up to two different set points (“sP1”, “sP2”)
and then selection of which one must be active. The effective set point can be selected:
- by parameter “EFsP” in the group of parameters “sP”.
- by key “C” if par. “key” = “sPsL”
11.0 CONTROL STATES:
The controller acts in three different ways: Automatic control (Auto), control OFF (oFF)
and manual control (oPLP). By using the key “conf” on the keyboard and suitably
programming par. “key” (“key” = oPLP, “key=oFF”), it is possible to pass from “Auto”
state to the state programmed on the parameter and vice versa.
(The instrument switches into “Auto” state at the end of auto-tunning). When switched
ON, it automatically assume its state at the last switch OFF.
11.1 Automatic Control (Auto):
Automatic control is the normal functioning state of the controller. When in Auto mode,
the device will function as per parameter programmed on par. cont.
11.2 Control OFF (oFF):
In this mode, all the outputs are deactivated.
11.3 Bumpless Manual/Open Loop Control (oPLP):
This option allows to manually program the power percentage given as output by the
controller by deactivating automatic control. When the instrument is switched to manual
control, the power percentage is same as last one supplied. To change the power output,
adjust the parameter manual reset “rs” in the “rEg” group.
12.0 CONTROL ACTIONS:
In automatic control, the controller can provide different control actions depending on
the parameter “cont” in “reg” group. The different control actions are explained as
below:

12
12.1 ON/OFF CONTROL:
All the parameters regarding ON/OFF control are listed in group “rEg”. This type of
control can be set by programming par. “cont”= onFs for ON-OFF action with symmetric
hysteresis OR onFA for ON-OFF action with asymmetric hysteresis. It drives the output
programmed as coP [selected by par. oPcF#5, 6, 7, 8 in oP], depending on the measured
temperature value, on effective set point, function mode (“func”) and on the hysteresis
(“hEst”).
The action can be explained as follows:
In case of reverse action i.e. HEAT being set on par. “Func” in “rEg” menu, the controller
activates the output when the process value “Pv” goes below [sP-hEst]. It de-activates
the output when the “Pv” goes above [“sP+hEst”] in case of symmetric ON-OFF control
and above “sP” in case of Asymmetric ON-OFF control. Similarly in case of direct action
i.e.
COOL being set on par. “Func”, the controller activates the output when the process
value “Pv” goes above (sP+hEsT) and deactivates the output when “PV” goes below
“SP-hEST” in case of symmetric ON-OFF control and “sP” in case of Asymmetric ON-
OFF control.
12.2 Neutral Zone ON/OFF Control (nr):
12.2.1 Action:
All the parameters referring to neutral zone ON/OFF control are listed in the group "rEg".
This type of control can be set when two outputs, configured by parameter “oPcf”
(“oPcF” = h1c2 configures oP1 as heater and oP2 as compressor) are programmed as
“coP” and the par. "cont” = nr. The neutral zone control is used to control processes in
which there is an element which causes a positive increase in temperature (eg. Heater,
Humidifier etc.) And an element which causes decrease in temperature (e.g. Cooler, de-
humidifier, etc.) Depending on measurements of effective set point "sP" and on

13
hysteresis "hEst", the control functions works on programmed outputs. The controller
activates the output configured as heater when process value goes below [sP-hEst] and
deactivates it once the Pv reaches sP. Further it activates the output configured on
cooler when process value goes above [sP+hEst]. The cooler output is deactivated when
Pv reaches sP again.
12.2.2 cdty Menu:
Compressor duty cycle "cdty" is used to protect compressor short cycling. It is a time
based activation of the compressor. The activation of compressor can be avoided till the
time set on parameter “cdty” thus providing the delay. Time programmed on "cdty" is
counted starting from last output deactivation and then even if the regulator requires to
switch on the corresponding output, the activation is delayed till the time set on “cdty”
elapses.
12.3 PID Control:
12.3.0 Single Acting PID Control:
All the parameters referring to PID control are listed in the group “rEg”. The single
action PID control can be obtained by programming par. “cont” = Pid and works on
output configured as “coP” (and selected by oPcF#5, 6, 7, 8 par in “oP” menu)Depending
upon the effective setpoint “sP”, function “FUnC” and on the instrument’s PID algorithm
the control output is calculated. The single action PID control algorithm foresees the
setting of following parameters:
“Pb” - Proportional Band.
“Int” - Integral Time
“dEr” - derivative time
“rs” - Manual Reset (if “Int=0” only)
for #5,6,7,8:
hct” - Heat output cycle time if “Func” = “hEAT”
OR “cct” - Cool output cycle time if “Func” = “cooL”
for #1,2,3,4: “ct” - Cycle time

14
12.3.1 Double Acting PID CONTROL (#5,6,7,8):
All the parameters referring to PID control are listed in the group “rEg”. The double
action PID control is used to control processes where there is an element which causes a
positive increase in temperature (ex. Heating) and an element which causes a decrease
in temperature (cooling). This type of control is selected by setting “cont” as Pid setting.
At least two outputs as “coP” with oPcF parameter representing which output acts on
heater and which acts on cooler. The effective set Point “sP” and the instruments
algorithm decides the controller output of Double Action PID control. The cycle times
“hct” (Heat cycle time: for output acting on heater) and “cct” (Cool cycle time: for
output acting on cooler) should have low value with frequent intervention of control
outputs so that good stability of process variable can be achieved, in case of fast
processes. It is recommended to use solid state relays to drive actuators. The Double
Action PID control algorithm needs the programming of following parameters:
"Pb” - Proportional Band
"hct" – Heat cycle time
"cct” – Cool cycle time
"Int" - Integral Time
"dEr" - derivative time
"rs" - Manual Reset (if "Int=0 only)
"coEF" – Coefficient Relation between power heating and cooling element. Range
between 0.1 to 10.
"coEf" < 1: represents that the cooling element is stronger than heating element.
“coEf” = 1: represents that the heating and cooling element are equally strong.
“coEf” > 1: represents that the heating element is stronger than cooling element.
13.0 AUTO TUNING:
Auto tuning is a process by which the controller automatically calculates the values of
dp, Int and dEr, suitable for the process. In this process, the controller carries out
several opertions on the process plant to determine these values.
Steps for Auto-tuning are as follows:
1. Program and select desired Set Point.
2. Program Par. “cont” =pid.
3. For single action PID control, program par. “Func” as “heat” if using heater or “COOL”
if using cooler.
4. Also program the output to which the final control element is connected as “coP”.
5. In case of Double action PID control, set “coP” on the two outputs selected using par.
“oPcF” to act on heater and cooler.
6. Progarm par. “Auto” as:
“1” - Tune at Every power ON. If auto-tuning is desired, each time the instrument is
switched ON.
“2” - Tune at first power ON. If auto-tuning is desired, the next time the instrument is
switched ON. Once the tuning is finished, the par. “Auto” is swapped automatically to
“OFF”.
“3” – Tune manually. If auto-tunning is to be started manually by pressing the config
key programmed as “stAt”
4”- Tune at every set point change or at the end of soft start. This activates auto-
tuning at every change of set point or at the end of soft-start cycle.

15
7. Switch OFF the instrument power and then switch it ON to start tuning if “Auto” is set
as “1” or “2” or by pressing config. key programmed as “stAt”. Flashing LED AT indicates
the activation of Auto-tunning function. To start the auto tune following condition needs
to satisfy:
if “Func“ is “HEAT”
PV < [SP - |SP/5|] if soft start is configured
OR
PV < [SP - |SP/3|] if soft start is not configured
if “Func“ is “COOL”
PV > [SP + |SP/5|] if soft start is configured
OR
PV > [SP + |SP/3|] if soft start is not configured
If the above conditions are not satisfied at the start of auto tune, the display will show
"ErAt" message and the instrument will take the control conditions according to previously
programmed PID. To make 'ErAt' disappear Press enter key. If auto tune is not completed in
10 hours, the instrument shows 'NoAt' on display. The cycle in progress in automatically
get stopped in case of sensor error. After correct PID parameters are tuned, the calculated
values are stored in instrument memory.
14.0 RAMP AND SOAK #5,6,7,8:
1. The PR-69 has provision for three ramps and three soaks corresponding to sP1, sP2
and sP3.
2. All parameters related to ramp functions in group ‘rEg’
3. Three strategies have been adopted that determine the state of ramp and soak in
case of power resumption after failure.
14.1 Power Down Resumption Mode (Prmd):
a. cont: The device keeps in memory the last set point value before the power failure.
After resumption, it starts from the same value and continues the profile. In case of
soak stage once the power is resumed, the stage continues for the remaining time.
b. rbck: The device starts from present Pv value and continues with the profile. In case
of power failure in soak stage, once the power is resumed and if Pv is not equal to the
target sP of the given soak stage, then starting from Pv the sP ramps up to the target sP
value with the slope of previous ramp. Once target sP is reached, device move to soak
stage which continues for the remaining time.
c. rsEt: On power failure, the entire ramp and soak profile is reset. At the end of the
profile irrespective of Pwrd, the device switches OFF all the control outputs.

16
14.2 Holdback (hbck):
14.2.0 Holdback In Ramp:
While in ramp mode if the difference between SP and PV value goes beyond Holdback
value, the SP ramping stops and it is held on the given value as long as PV < (SP-hbck)
OR PV > (SP+hbcK) range.
14.2.1 Holdback In Soak:
While in Soak mode if the difference between sP and Pv value goes beyond Holdback
value, the soak timing is stopped and it is resumed when PV comes back within (SP-
hbck) and (SP+hbcK) range.
15.0 Soft Start :
All parameters referring to the soft start functioning are contained in the group “rEg”.
The soft start functioning allows limitation of output power when instrument is switched
on for a limited period of time. Following parameters are needed:
“sst” - Soft start time in hh: mm
“ssth” - soft start threshold
“ssP” - soft start power
Soft start functionality will abort when sst or ssth whichever earlier is met.
16.0 ALARMS:
16.1 Alarm Types:
1.Absolute low (“AbLo” on display):
Alarm is activated if PV goes below A1th and is deactivated if PV goes above
(A1th+A1hY).
2.Absolute high (“Abhi” on display):
Alarm is activated if PV goes above A1th and is deactivated if PV goes below (A1th-
A1hy).
3.Absolute band (“AbbA” on display):
Alarm is activated if PV goes above A1hi or below A1Lo. It is deactivated if it goes below
(A1hi-A1hy) or above (A1Lo+A1hy).

4.Deviation low ( “dELo” on display):
Alarm is activated if PV goes below (Effective Set Point - A1th) and is deactivated when
it goes above (Effective Set Point–A1th + A1hy).
5.Deviation high(“dEhi” on display):
Alarm is activated when PV goes above Effective Set Point +A1th) and is
deactivated When it goes below (Effective Set Point + A1th-A1hy).
6.Deviation band (“dEbA” on display):
Alarm is activated when PV goes above (Effective Set Point + A1hi) or below
(Effective Set Point - A1Lo) and is deactivated when PV goes below (Effective Set Point
A1hi - A1hy) or above (Effective Set Point - A1Lo + A1hy).
7.Output low(“oPLo” on display):
Alarm is activated if output goes below o1LV and deactivated when output goes above
(o1LV+o1hs).
8.Output high(“oPhi” on display):
Alarm is activated if output goes above o1hv and deactivated when output goes below
(o1hv-o1hs).
16.2 Alarm Functions:
1. Acknowledged: -
a.+0 = Alarm not acknowledged. Alarm remains active in alarm conditions only.
b. +1 = Alarm acknowledgement active – the alarm remains active in alarm conditions
and deactivated when alarm conditions does not exist. But while alarm condition still
exists, if properly programmed 'C' key is pressed, then the alarm is deactivated.
2. Delayed: -
a.+0 = Alarm is activated immediately on alarm condition occurrence.
b. +2 =Alarm is activated after the delay set on par. A1dL.But, if alarm condition
disappears while the controller is still executing the delay, then the alarm willnot be
activated. Once activated, the alarm alarm will be deactivated only after controller sees
non-alarm condition. There will be delay executed while deactivating the alarm.
3. Latched:-
A.+0 = Alarm not latched – alarm remains active in alarm conditions only.
4. No alarm at power on:
a.+0 = Alarm is activated when there are alarm conditions.
b. +8 = if the instrument is in alarm conditions when switched on, then alarm is not
Activated. It will be activated once Instrument goes in non- alarm condition and back to
alarm condition.
5. No alarm at sP change: -
a.+0 = alarm is activated when there are alarm condtions
b. +16 = If the instrument goes in alarm conditions after changing the set point, the
alarm will not be activate. It will be activated, once instrument goes in non-alarm
condition and back to alarm Condition.
Note:
Alarm types and functions are explained for Alarm 1.The explanation is same for Alarm
2.Binary addition of alarm function allows combination of different function.
E.g.
If it is required to have no alarm at power On [8] and no alarm at SP change [16], set
function as 24.

17.0 PROGRAMMING:
Follow given procedure to program the device:
1. Press key ‘E’ to enter menus. ‘PV’ display shows “codE”, which is blinking and ‘SV’
display shows “0”.
2. Enter code as “69” using ‘UP’ key. Press key ‘E’ to enter into menu. If wrong code is
entered, then the device exits from programming mode. If correct code is entered,
the device enters into the set of menus.
3. Using ‘UP’ or ‘DN’ Key we can move to desired set of parameter.
4. Press key ‘E’, to enter the group of parameters related to the main menu. Here, the
‘PV’ display shows the menu and ‘SV’ shows the value programmed on it.
5. To change this value, press key ‘E’. Using ‘UP’ or ‘DN’ key, select the value to be
entered. Press key ‘E’ to confirm the value or key ‘C’ to maintain the previous value.
6. Whenever the value of the menu is being edited, the 'PV' display blinks. Here, 'UP’
and 'DN’ key change the value on ‘SV’ display. When the display is not blinking, we can
move to next menu using ‘UP’ or ‘DN’ key. To exit from the menu press key ‘C’.
7. Key ‘C’ acts as exit key when in programming mode. While on main screen, when
'PV' displa shows temperature and ‘SV’ display shows user configured value, it performs
the function as configured on it in the “key” parameter of “conF” menu.
