List of error codes
In the event of a fault, the error log of the module controller and the LED display on unit controller provide a
description of the fault. The LED display on the operation panel (unit controller) shows the fault code and the
name of the fault-causing circuit. The module controller shows the date and time when the fault occurred, the
failed module and circuit names, error code and its description.
In the event of a fault, the circuit name appears in the LED display on the unit controller operation panel. The digit
"0" in the circuit name position denotes the entire module; the letter "A" denotes Circuit A, the lowercase "b"
denotes Circuit B, the letter "C" denotes Circuit C, and the lowercase "d" denotes Circuit D. The letters "C" and
"A" also signify a failure of the upstream unit (Circuits C and D) and the downstream unit (Circuits A and B)
respectively.
