Fault/error indication
If a fault or error occurs in the motor or motor control unit, the latter will indicate this to the
program control unit board. Information on these errors, besides appearing as an error
code on the display, is also provided by a yellow LED on the motor control unit board. To
understand this additional inform-ation, the pattern of flashes from the LED has to be
observed and compared with this chart:
