4.7 Relay Reset
Figure 16: Relay Reset
If the Warning and/or Alarm Relays are configured as latching, it is possible to manually reset
the relays, once the detected gas level has dropped below the configured set point. This can be
accomplished in three ways:
1. The relays can be reset using the MODBUS Interface. Refer to Section 5.0.
2. The relays can be reset using the magnetic switch in the Base Unit. Place the magnet
over the GM logo on the cover of the Base Unit. After three seconds the display shows
“
rSt
”. Remove the magnet and the relays are reset.
3. The relays can be reset using the Remote Reset input terminals on TB2. Connect a
normally open switch between terminal TB2-7 and TB2-8. Closing the switch
momentarily resets the relays. General Monitors explosion proof switch, P/N 30051-1
can be used for this purpose and installed in one of the unused ¾” conduit entries on
the TS4000.
