POWER-UP
Upon power-up, all displays and indicators are lit on for approximately 3 seconds. This is followed by the indication of the
controller model name on the Upper Readout and the firmware version on the Lower Readout, for
approximately 1 second.
MAIN DISPLAY MODE
After the Power-up display sequence, the Upper Readout starts showing the measured PV (Process Value) and the Lower
Readout displays the Setpoint Value. This is the MAIN Display Mode that shall be used most often.
% Output Power Indication
In PID control mode, the Lower Readout can be toggled using ENTER key to indicate either % output power or setpoint value
SP. The output power is indicated with the left most digit showing ‘P’, ‘H’ or ‘C’ depending upon uni-directional (Heat or Cool) or
bi-directional (Heat and Cool) control mode. Refer Figure 2.1 below.
Tune Mode Indication
The Lower Readout flashes while the controller is Tuning. Do not disturb the process or alter any parameter values
while Tuning is in progress. The “Tune” message automatically disappears upon completion of Tuning procedure.
Profile Mode Indications
While a Profile Cycle is in progress, the front panel indicator ‘PRF’ flashes or glows steadily. The steady glowing indicates that
though the profile is active, it is currently in HOLD state. Also, the Lower Readout shows the Profile Setpoint instead of the
control setpoint SP. The % Output Power (if PID Control) can be viewed by toggling the Lower Readout using ENTER key.
Note :
While Profile Cycle is in progress, the Control Setpoint SP can still be adjusted on Lower Readout. While the Lower Readout shows Profile
Setpoint, use UP/DOWN keys to adjust the control setpoint SP as described earlier.
PV Error Indications
The PV Error type is flashed on the Upper Readout. For different errors and the causes, refer Table 2.1 below.
BASIC OPERATION
Adjusting SP (Control Setpoint)
If permitted at Supervisory Level, the SP value can be directly adjusted on the Lower Readout in the MAIN Display Mode.
While the Lower Readout shows the control setpoint, step through the following sequence for adjusting the SP value :
1. Press and release UP or DOWN key once. The Lower Readout starts flashing.
2. Use UP/ DOWN keys to adjust the SP value.
3. Press and release ENTER key. The Lower Readout stops flashing and the new set value is registered and stored.

CONTROL / ALARM STATUS UNDER PV ERROR CONDITIONS
a) The tuning, if in progress, is aborted.
b) The Profile Cycle, if in progress, enters in HOLD state.
c) Under Over-range or Under-range error condition, all the control outputs are switched off. However, under Sensor Open
error, the PID control output power is maintained at the value set for the parameter “Sensor Break Output Power” on
PAGE-12.
d) For Alarm activation, the under-range condition is treated as minimum PV, whereas the over-range and open conditions
are treated as maximum PV. Thus, Process High, positive Deviation Band and Window Band alarms activate under Over-
range/Open error. Similarly, Process Low, negative Deviation Band and Window Band alarms activate under Under-range
error.
• MANUAL MODE OPERATION
This operation mode is available only if the control action is PID and if the manual mode operation is permitted at
supervisory level. In this mode, the controller operates in Open loop mode wherein the % Output Power is manually
adjusted by the operator. This mode is often used for process start-up to make sure that the process equilibrium is
achieved before the control is transferred for subsequent automatic (closed loop) control. The controller ensures a
bumpless Auto / Manual transfer.
The manual mode can be activated or de-activated using ENTER key. While in manual mode, the Upper Readout shows PV
while the Lower Readout shows % Power that can be adjusted using UP/DOWN keys.
Follow the steps below to enter (Activate) into Manual Mode and to revert to (De-activate) Automatic Mode.
1. Hold ENTER key pressed for approximately 2 seconds until front panel indicator M (Manual Mode) turns on.
2. Release Enter key. The controller is now placed in Manual mode. The Upper Readout displays the PV and the Lower
Readout displays the %Output Power (with the leftmost digit indicating either P (Unidirectional control) or H / C
(Bidirectional control)).
3. Adjust the Output Power using the UP and DOWN keys. Note that in Unidirectional mode, the Output Power is adjustable
between the set Power Low and Power High limits. However, in Bi-directional mode, the Output Power is adjustable from
-100% to +100%.The power range from -100% to 0 is Cool Power (with the leftmost digit indicating C) and 0 to +100% is
Heat Power (with the leftmost digit indicating H).
To de-activate the Manual mode; Hold the ENTER key pressed for approximately 2 seconds until the front panel indicator M
turns off. The controller now enters into Auto control mode with the first power same as that was adjusted last while in Manual
mode.

Notes:
1. If the Manual mode is activated while a Profile Cycle is in progress; the profile segment (Ramp or Soak) continues to run uninterrupted.
However, the % output power is in accordance with the user set value. The PV, thus may not follow the setpoint profile closely.
2. The Manual mode Activation / De-activation is suppressed while the Tuning is in progress. However, the Tuning procedure can be
activated regardless of whether the controller is in Auto or Manual control mode.
3. The Standby Mode (explained later in this section) over-rides the Manual control mode (if active).
4. If the power fails while the Manual Control Mode is active; upon resumption of power the controller continues to remain in Manual control
mode with the last user set power.
• STANDBY MODE
This mode, allows the operator to put the controller in ‘indication-only’ mode wherein all the output control signals as well as
Alarm Relays are forced OFF. This may be desired prior to the start of a new process batch.
If enabled at supervisory level, the standby mode can be activated or de-activated by setting the parameter ‘Standby’ to Yes
or No respectively. The standby parameter is available on operator page, explained later in the section.
Notes:
1. The Standby and Tuning modes are mutually exclusive. Similarly, if Standby mode is activated while the controller is tuning, the controller
aborts tuning operation and enters Standby mode.
2. If the Power Supply to the controller is switched-off or a Power-failure occurs while the controller is operating in Standby mode; upon
resumption of power, the controller continues to operate in Standby mode.
OPERATOR PAGE AND PARAMETERS
The controller provides a separate page that contains parameters that require frequent settings by the operator. The page is
called Operator Page and the parameters are called Operator Parameters. The availability of operator parameters is
controlled at supervisory level and the parameter setting is not affected by the master lock status.
Accessing Operator Page & Adjusting Parameters
Step through the following sequence to open the operator page and to adjust the operator parameter values.
1. Press and release PAGE key. The Lower Readout shows (PAGE) and Upper Readout shows (0).
2. Press ENTER key. The Lower Readout shows prompt for the first available operator parameter and the Upper Readout
shows value for the parameter.
3. Use UP / DOWN keys to adjust the value and then press ENTER key to store the set value and scroll to next parameter.
The controller automatically reverts to MAIN Display Mode upon scrolling through the last operator parameter. Alternatively,
use PAGE key to return to MAIN Display Mode.
The operator parameters are described in Table 2.2. Note that the parameters presented on operator page depend upon the
functions selected/enabled and supervisory level permissions.
The operator parameter list mainly includes :
a) Profile related commands like Start, Abort, Pause, Skip etc.
b) Standby mode entry / exit.
c) Control Setpoint (SP) value.
d) Alarm-1 Setpoint / Band values.
e) Alarm-2 Setpoint / Band values.

2. Use UP / DOWN keys to set the desired PAGE NUMBER.
3. Press and release ENTER key. The Lower Readout shows the prompt for the first parameter listed in the set PAGE and
the Upper Readout shows its current value. If the entered PAGE NUMBER is invalid (contains no parameter list or any
associated function), the controller reverts to the MAIN Display Mode.
4. Press and release the ENTER key until the prompt for the required parameter appears on the Lower Readout. (The last
parameter in the list rolls back to the first parameter).
5. Use UP / DOWN keys to adjust the parameter value. (The display flashes if UP key is pressed after reaching the maximum
value or DOWN key is pressed after reaching the minimum value).
6. Press and release the ENTER key. The new value gets stored in the controller’s non-volatile memory and the next
parameter in the list is displayed.
The Figure 3.1 illustrates the example of altering the value for the parameter ‘Control Output’.

MASTER LOCKING
The controller facilitates locking all the PAGES (except Operator PAGE) by applying Master Lock Code. Under Locking, the
parameters are available for view only and cannot be adjusted. The Master Lock, however does not lock the operator
parameters. This feature allows protecting the rather less frequently used parameters against any inadvertent changes while
making the frequently used operator parameters still available for any editing.
For enabling / disabling the Lock, step through the following sequence:
Locking
1. Press and release PAGE key while the controller is in the MAIN Display Mode. The Lower Readout shows PAGE and the
Upper Readout shows 0.
2. Use UP / DOWN keys to set the Page Number to 123 on the Upper Readout.
3. Press and release ENTER key. The controller returns to the MAIN Display Mode with the Lock enabled.

tuning operation in progress.
Parameter Description
OVERSHOOT INHIBIT
(Available for PID control only)
Enabling this feature controls the PV rise or fall upon process
start-up in order to reach the control setpoint with as minimum
overshoot as possible.
1.0 to 2.0
(Default : 1.2)
OVERSHOOT INHIBIT FACTOR
(Available for PID control with Overshoot Inhibit enabled )
This parameter adjusts the effectiveness of the Overshoot Inhibit
feature. Increase the value if the overshoot is curbed but the PV
takes longer to reach the SP. Decreases the value if the overshoot
persists.

AUXILIARY SETPOINT OR SERIAL
COMM.OPTION SELECTION
This parameter allows the user to configure the controller in either
Auxiliary Setpoint or Serial Communication mode options. When
the ‘Auxiliary Setpoint’ option is selected, the controller treats the
Auxiliary Setpoint (ASP) same as control (main) Setpoint (SP) and
attempts to maintain PV at the Auxiliary Setpoint upon detecting
the potential free contact closure of external switch/Relay or a
TTL-compatial voltage level below 0.5 Volts by the Hardware
module.
When the ‘Serial Communication’ option is selected, the Following
param ete rs ar e ava ila ble a nd ap pli cable fo r Ser ial
Communication Function if the respective hardware module is
fitted.
BAUD RATE
Communication speed in ‘Bits per Second’. Set the value to match
with the host baud rate.
CONTROLLER ID NUMBER
Unique numeric code assigned to the controller for identification
by the host. Set the value as required by the host.
COMMUNICATION WRITE ENABLE
Setting to ‘No’ disallows the host to set or modify any parameter
value. The value however can be read by the host.
