Principle
The ball bearings can be regreased 2 times before to be
changed.
The maintenance counter allows to account for these
different operations (0-1-2) and to set their frequency limits
(in hours).
When leaving the factory, the
«BEARING MAINT.»
counter is reset at «0» and the frequency fixed at 5000h:
this can be modified depending on the defined values in
the greasing schedule (
see D 40
) or on the acquired
know-how.
Maintenance operations are automatically displayed by
the controller since this reset.
The user will have to perform the regreasings or ball
bearing replacement and to increase the
«BEARING
MAINT.»
and
«BEARING LIMIT»
counters.
Example of operation with a maintenance frequency fixed to 5000h*.

*The maintenance frequency for regreasing or ball bearing replacement could be modified along the life time of the bearings:
it could be justified by a process evolution, or the user’s know-how.
