Dry Contact Relay
To manually control the Relay Mode of Operation so that the relay is always on, or
always off, select On (or Off).
You can also set the Relay Mode of Operation to Automatic so that the relay will
automatically turn on if a fault is detected in the system.
The Automatic option will activate the relay on any fault/warning of any Xanbus or
Modbus device in the network. The only Modbus fault/warning supported by
relay triggering in the Combox v3.01 release is the Conext RL Ground Fault
(Code: 0702).
When you choose the fourth option for Relay Mode of Operation which is Conext
RL Ground Fault, the relay gets activated only on ground fault in the Conext RL
and not on any other fault/warning in the system. When a Conext RL is connected
to the power system and it detects a Ground Fault event, the Dry Contact Relay
shall remain open until the ground fault event is cleared.
When the Ground Fault event is detected in the Conext RL, you have the option
to be notified by email (Enabled or Disabled) and select the frequency of
notification (30, 60, and 720 minutes). See “E-mail Reporting” on page 3–16.
