Faults

Both bUS [Option Communication Error] and EF0 [Option Card External Fault] can
appear as a fault. When a fault occurs, the digital characters shown on the keypad does not
flash but stay lit. The keypad ALM LED also stays lit. When an alarm occurs, the ALM
LED flashes.
Note:
Normally, o2-24 = 2 [LED Light Function Selection = Keypad LED Light Disable] is set as a factory default,
so the ALM LED does not light.
