Monitoring function and emergency program
COLL
Address conflict on CAN bus
The set module number is already assigned.
Set a different module number!
buS
CAN bus error
No communication over the CAN
bus
Check the CAN bus connection!
ErCo
CAN bus communication error
The device has detected activities on the field bus,
but is not being controlled by the corresponding
master module. Check address setting and
parameter settings of the master module!
EE
Data fault in non-volatile memory A power surge may destroy the set parameters.
Operation is carried out with the factory default
settings. Newly enter all storage locations! De-
energise the control unit!
