The message numbers serve two purposes:
1. They indicate why the controls were unable to
carry out the drive command given.
2. They indicate which components are faulty.
This facilitates better and faster service on site,
and only the control components identified as
being faulty need be replaced.
The controls remain in message mode until they switch
to operating mode or diagnostic mode.
Switching to operating mode
The controls switch to operating mode as soon as they
receive a movement impulse.
Switching to diagnostic mode
The controls can be switched to diagnostic mode from
either message mode or operating mode.
• Give the (P) button a short press.
The controls switch to diagnostic mode and display the
last fault.
