KEY DEFINITIONS
| Symbol | Key | Function |
|---|---|---|
| PROGRAM MODE | Keep pressed for approximately 5 seconds to enter / exit Set- |
up mode.
| **** DOWN| Press to decrease the parameter value. Pressing once decreases the value by one count; holding the key pressed speeds up the change.
| **** UP| Press to increase the parameter value. Pressing once increases the value by one count; holding the key pressed speeds up the change.
MAIN MODE DISPLAY
Upon switching on the power to the Indicator, all displays and indicators are
lit on for approximately 3 seconds. This is followed by the indication of the
Indicator model name for approximately 1 second. The Indicator now enters MAIN
Mode wherein the display shows the PV proportional to the Input DC signal
within user set Range Low and Range High Limits.
PV ERROR INDICATION
In case of PV Error the following messages are flashed.
| Message | PV Error Type |
|---|
__
| Over-range (PV above Max. Range)
__
| __ Under-range (PV below Min. Range)
__
| __ Open (Sensor open / broken)
PARAMETER SETTINGS
The Indicator offers various parameters for setting-up the configuration and operation modes. Each parameter has a unique name and a settable value. For example, the parameter ‘Input Type’ is identified by its name and has the settable values ‘RTD’ ( ) and ‘RTD.1 ’ ( ).
Further, the parameters are organized under different groups. Each group of
parameters is called PAGE. Each page is assigned a unique number for its
identification and access. The various pages along with their parameters are
described later.
Follow the steps below for setting / changing any parameter value.
- Keep PRG key pressed (approximately 5 seconds) until display shows PAGE ( ). Release the key.
- Press PRG key again. Display shows page number 0.
- Press PRG key if page 0 is the desired page number (operator page) or use UP / DOWN keys to set the desired page number and then press PRG key. The display now shows the name for the first parameter in the page.
- Use UP / DOWN keys to select the desired parameter name.
- Press PRG key. The display now shows the value for the selected parameter.
- Use UP / DOWN keys to change the parameter value.
- Press PRG key to save the new value. The display shows the name for the next parameter in the list.
- Repeat steps 4 to 7 for any other parameter settings, if required.
- For returning to Main Mode, keep PRG key pressed (approximately 3 seconds) until the display starts showing PV.
The following figures step-wise show an example of changing the value for the parameter ‘Resolution’ from ‘1’ to ‘0.1’. The parameter ‘Resolution’ is available on PAGE-12 and is second in the list. Notice that from MAIN Mode the appropriate page number is selected first and then the desired parameter name is selected for changing the value. Finally, PRG key is used to return back to MAIN Mode.
Table 3.1
PAGE – 0 : OPERATOR PARAMETERS
| Parameter Description | Settings |
|---|
ALARM-1 SETPOINT
Available only if selected ‘Alarm-1 type’ is either ‘Process High’ or
‘Process Low’. This parameter value sets the Upper (Process High) or Lower
(Process Low) Alarm Limit.| Minimum to Maximum Range specified for the
selected Input type
ALARM-2 SETPOINT
Available only if selected ‘Alarm-2 type’ is either ‘Process High’ or
‘Process Low’. This parameter value sets the Upper (Process High) or Lower
(Process Low) Alarm Limit.| Minimum to Maximum Range specified for the
selected Input type
Table 3.2
PAGE – 1 : PV MIN / MAX PARAMETERS
| Parameter Description | Settings |
|---|
MAXIMUM PROCESS VALUE
This gives the maximum PV recorded since Power-up or last reset.| **
View Only
MINIMUM PROCESS VALUE
This gives the minimum PV recorded since Power-up or last reset.| **
View Only
RESET PV MONITOR
This command resets Maximum value and Minimum value to the instantaneous
Process Value.|
Table 3.3
PAGE – 12 : INPUT CONFIGURATION PARAMETERS
| Parameter Description | Settings |
|---|
INPUT TYPE
The Indicator is factory calibrated for either J, K, R, S Thermocouple or
RTD Pt100 (3-wire) sensor. Select the appropriate input type as per the type
of Thermocouple / Sensor connected .
The table below shows the temperature ranges for each input type.|
OFFSET FOR PV
Zero offset for measured PV. Displayed PV = Actual PV + Offset| -1999 to
9999 for Thermocouple & RTD (1°C)
-199.9 to 999.9 for RTD (0.1°C)

PAGE – 11 : ALARM PARAMETERS
| Parameter Description | Settings |
|---|
ALARM-1 TYPE
Type for Alarm-1.|
ALARM-1 HYSTERESIS
Differential (dead) band between the ON and OFF alarm states. Keep it large
enough to avoid frequent switching.| 1 to 999 or 0.1 to 99.9
ALARM-1 LOGIC
Normal : The alarm-1 output remains ON under alarm conditions; OFF
otherwise.
Reverse : The alarm-1 output remains OFF under alarm conditions; ON
otherwise.| **
ALARM-1 INHIBIT
Yes : The alarm-1 is suppressed during start-up alarm conditions.|
No : The alarm-1 is not suppressed during start-up alarm conditions.| **
ALARM-2 TYPE
Type for Alarm-2.|
ALARM-2 HYSTERESIS
Same as Alarm-1 Hysteresis.| 1 to 999 or 0.1 to 99.9
Alarm-2 Logic
Same as Alarm-1 Logic.|
ALARM-2 INHIBIT
Same as Alarm-1 Inhibit.|
