Power cycling the CIO module while there is no communication to the AGC will reset the set-
tings results, and the relay will be set as a status relay until communication is established. The
CIO configuration is stored in the AGC, and this means that the CIO module will be configured
when the communication to the AGC is available.

1. Relay type
This setting has two states: Status relay and Configurable.
If it is used as a status relay, the relay will stay closed as long as the state of the module is OK, which corre-
sponds with a constant green status LED (see Status LED). If the relay is used as a status relay, the settings
below are disregarded.
2. CAN bus failure set output
This setting has three levels: Low, High and Stay. In case of a CAN bus failure, the related relay will change
its state based on this setting. If it is set to Stay, the relay will keep its current state until communication is
working again.
3. Relay function
The relay function can be set to five different settings:
Alarm relay ND
The related relay is used as an alarm relay of the type "ND" (Normally De-energised).
The relay is activated until the alarm that caused the activation is acknowledged and gone.
Limit relay
The relay will activate at a certain predefined limit set point. When the condition that activated the relay has
returned to normal, and when the delay has expired, the relay will deactivate. The delay is adjustable.
