15) VALVE ENABLE
Cause:
It occurs when the uC master try to activate an output but the supervisor uC
doesn’t activate the enable.
Troubleshooting:
Check if some alarm is present on supervisor uC. Otherwise a fault in the
hardware is present, the board must be replaced.
16) NO CAN MSG 5
Cause:
Timeout on the local CAN BUS
Troubleshooting:
Switch OFF and ON. If the alarm is still present replace the board.
17) WAITING FOR NODE

The controller receives from the CAN the message that another controller in
the net is in fault condition; as a consequence the VCM controller itself
cannot enter an operative status, but has to WAIT for the other controller
coming out from the fault status.

Cause:
Wrong customer ID code found in the protected area of memory where this
parameter are stored
Troubleshooting:

communicates on CAN bus

Troubleshooting:
Check the CAN connection on Mini Lever or Joystick side. Verify that the Mini
Lever or Joystick communicate on CAN bus
