Operate the Module
Relay Output Module
Each status indicator represents the state of that particular channel or output.
Normal expected status indicator states for a healthy system are all solid green.
If the output is not enabled, all associated status indicators are off.
If enabled: Blue if the relay is inhibited or the link is halted (output state being
held).
Otherwise:
• Red when the relay contacts are in the alarm state
• Green when the relay contacts are in the non-alarm state
The active color flashes for any channel with a detected relay drive fail and for
all enabled channels during a link fault.
IMPORTANT
The definition of the contact state that red or green represents is a part of the
expansion module configuration.

(1) Relay is held when inhibited or bus halt. Halt is where the auxiliary module is advised to extend its link timeout temporarily.
(2) ANY color flashing indicates Bus or Relay drive fail. Bus fail is indicated similarly on all enabled channels.
(3) Relay in Alarm means that the Voted Alarm that is associated with the relay is in the alarm state, or that any fault conditions that are associated with the relay are faulted.
