(Relays 3 & 4 Optional)
If Instrument Type is set for BATCHER,
Choose Rate, Total, Alrm, Ovr or NA.
If Instrument Type is set for RATE/TOTAL,
Choose Rate, Total, Alrm or NA.
If Rate / Alrm selected, enter desired relay activation
delay value.
If Total Selected, Enter desired Relay Duration.
Select the Relay Activation for Rate/Alrm.
Low: Relay activates when reading is below setpoint.
High: Relay activates when reading is above setpoint.
Enter the desired Setpoint. The setpoint 3 can be edited
in the "Run Mode" using the 4 key (9 key for Relay 4).
If Rate, selected, Enter desired Relay Hysteresis.
NOTE:
Settings for Relays
3 & 4 may be en-
tered even if relays
are not supplied.
The settings will
still trigger display
alarm messages if
applicable.
RELAY NOTES & CONSIDERATIONS
1. Relay activation is based on the computed readings not the displayed value. Therefore the display
damping factor will not affect the relay response time. The RELAY DELAY feature allows the user
to enter a time delay for relay activation. This feature is very useful in applications where short over/
under range conditions are not considered alarm conditions.
2. When INSTRUMENT TYPE is set to batcher, Relay 1 is reserved for PRESET and Relay 2 is re-
served for PREWARN or NA (not assigned).
3. Setting the relays to NA (Not Assigned), will allow the relay activation to be controlled via the RS-
232 Serial and/or RS-485 Modbus ports. It also allows the Presets to be used for other numeric
entry values via serial commands which can be part of the print list.
4. Relay 3 and Relay 4 settings may be used to trigger display alarm conditions even if the relays are
not supplied.
