Before beginning a maintenance, we recommend registering
this on bp408 in the service menu under
MAINTENANCE > MAINTENANCE FUNCTIONS > MAINTENANCE
ON
This means that fault information is no longer sent via remote
data transmission and the system is visualised as "In
Maintenance".
As part of the usual maintenance work, the following checks
must be carried out on the control systems bp408:
 General visual inspection for possible dust deposits,
moisture or corrosion. If they are present, they must be
removed.
 Are the connections of the control system mounted
correctly?
 Do the fault memory stack and/or the fault
list display errors? Check registered fault
notifications and, where appropriate,
delete them.

Check notifications and the notification
stack
(recorded notifications) for
anomalies.
 For the emergency lighting unit, it must be
ensured that the capacity of the battery is
sufficient for one hour of emergency
lighting in the car.

During the use of uninterruptible power
supply systems (UPSs), the maintenance
instructions in the attached manuals must
be complied with.
 The toothed belts of an absolute encoder system are maintenance-free under
normal conditions.
Warning !
