These connections are to the SPDT FAULT relay. The FAULT output configuration is normally energized and non-latching. This is the standard output configuration and it cannot be changed.

The FAULT circuit will be activated during the time-out function, a low power or loss of power condition, or during a failed COPM check. During these conditions, the FAULT relays will de-energize and the analog output signal will drop to 0 mA (2 mA for COPM Faults, 3.5 mA with HART or 1.25 mA for HART with small current enabled) for the duration of the FAULT. The FAULT relay contact rating is 8 A @ 24 VDC.

Refer to the figure in Sustained Alarm Relay for all relay connections.
