READOUTS
The Upper Readout is a 5 digit, 7-segment bright red LED display and usually displays the PV (Process Value). In Set-up
Mode, the Upper Readout displays parameter values/options.
The Lower Readout is a 5 digit, 7-segment bright green LED display and usually displays Process Value Units. In case of any
active Alarm(s), the Lower Readout flashes Alarm Status information. In Set-up Mode, the Lower Readout displays the names
(identifier tags) for the parameters.
INDICATORS
The front panel comprises 4 LED indicators that show Alarm status. Refer Table 1.1 below for details.
KEYS
There are six tactile keys provided on the front panel for configuring the indicator, setting-up the parameter values and
selecting Operation / Display Modes. Refer Table 1.2 below.

ALARM STATUS UNDER PV ERROR CONDITIONS
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 Alarm turns ON under Over-range/Open error. Similarly, Process Low Alarm
turns ON under Under-range error.
OPERATOR PAGE AND PARAMETERS
The parameters that require frequent settings are organized on a separate page, called the Operator Page. The availability of
operator parameters is controlled at supervisory level and the parameter setting cannot be locked by the Master Lock.
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 ‘OPR’ key. The Lower Readout shows prompt for the first available operator parameter and the Upper
Readout shows value for the parameter.
2. Use UP / DOWN keys to adjust the value and then press ENTER key to store the set value and scroll to the next parameter.
The automatically reverts to MAIN Display Mode upon scrolling through the last operator parameter. indicator
Alternatively, use PAGE key to return to MAIN Display Mode.
Note:
The Operator Page can also be accessed through PAGE-0. (The pages and parameters are explained in next section).
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.
POWER-UP
Upon power-up, all displays and indicators are lit on for approximately 3 seconds. This is followed by the indication of the
indicator 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 user set Units for Process Value. This is the MAIN Display Mode that shall be used most often.
Alarm Status Information
In case of any Alarm (or Alarms) becoming active, the Lower Readout flashes the related Alarm details in the format ‘Ax.YY’,
where x is the Alarm Number (1, 2, 3 or 4) and YY is Alarm Type (Lo or Hi) For example means Alarm-1 is active and
the set Alarm Type is Low. In case of multiple Alarms, each Alarm Status is flashed sequentially with 3 Seconds time interval.
PV Error Indications
The PV Error type is flashed on the Upper Readout. For different errors and the causes, refer Table 2.1 below.

The operator parameter list mainly includes :
a) Min / Max Process Monitoring Parameters.
b) Setpoint Values for all 4 Alarms ( Alarm-1 to Alarm-4).

5
The various parameters are arranged in different groups, called PAGES, depending upon the functions they represent. Each
group is assigned a unique numeric value, called PAGE NUMBER, for its access.
The parameters are always presented in a fixed format: The Lower Readout displays the parameter prompt (Identification
Name) and the Upper Readout displays the set value. The parameters appear in the same sequence as listed in their
respective sections.
SET-UP MODE
The Set-up Mode allows the user to view and modify the parameter values. Follow the steps below for setting the parameter
values:
1. Press and release PAGE key. The Lower Readout shows PAGE and the Upper Readout shows page number 0. Refer
Figure 3.1.
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 reverts to the MAIN Display Mode.indicator
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 indicator’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 ‘Input type’.

Notes
1. Each page contains a fixed list of parameters that are presented in a pre-determined sequence. Note however that availability of a few
parameters, called Conditional Parameters, depend upon the settings for some other parameters. For example, the parameter ‘Alarm
Setpoint’ is available if corresponding ‘Alarm type’ is set to other than ‘none’.
2. To exit the set-up mode and return to the MAIN Display Mode, press and release PAGE key.
3. If no key is pressed for approximately 30 seconds, the set-up mode times out and reverts to the MAIN Display Mode.
MASTER LOCKING
The indicator 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 indicator 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 indicator returns to the MAIN Display Mode with the Lock enabled.
The Figure 3.2 below illustrates the Locking procedure.
