Fault-finding

There are fault-finding charts for all error codes in Chapter 12, “Fault-
finding”.

Error indication patterns, green LED

The green LED on the MCU board is normally lit except for a brief pause
approx. once every five seconds (pattern which indicates “OK”).

When the microprocessor for the PCU is removed from the machine or has
reset status, the LED will be lit without flashing.

When the MCU current-limiting function is activated, the LED will instead
flicker, and the flashing pattern which indicates “OK” will be suspended for
as long as the current-limiting function is activated. When the MCU current-
limiting function ceases, the pattern of flashes indicating “OK” will return
after 10 seconds.
