2Check that the applicable alarm relay actuates properly depending on what you have set at prompt AxSxTYPE.

If it does, check the field wiring.

3Check the contacts.

4Change the relay and/or the current output board.

5Change MCU board.

If the alarm type is set for PV, place the controller in manual mode. Vary the input to raise and lower the PV around the setpoint. Listen for a click from the relay as the PV moves in either direction and note that the proper ALM1 or ALM2 is lit.

EXAMPLE: If the alarm is set for MAN, put the controller into manual mode. The alarm light is ON. Put the controller into automatic mode and the alarm light is OFF.

Make sure the NO or NC contact wiring is correct.

Refer to Section 2 - Installation for relay contact information.
