Relay Configuration - GasTech GTA-4100R Operator's Manual

Relay Configuration

Each channel has three alarm relays, AL2 (alarm 2) AL1 (Alarm 1) and Fault. Each of these relays can be set as
energized or non-energized.
NOTE: When a relay is set to energized, the normally open contacts become normally closed contacts.
This configuration allows warnings or alarms to be activated in the case of a power failure.
AL2 jumper AL1 jumper Fault jumper
Moving the jumper directly above the relay to the desired position changes the normal status of these relays.
