Inspection and service
Danger! Loss of the safety function because of dam-
age to the system. In case of damage, the affected
module must be replaced completely. Replacement
of individual parts of a module (e. g. parts of the
evaluation module) is not permitted.
Exception: Pre-assembled replacement lids (available
as spare parts for some MGB versions).
Regular inspection of the following is necessary to
ensure trouble-free long-term operation:
f
Check the switching function
f
Check the secure fastening of the devices and the
connections
f
Check for soiling (e.g. the ventilation slots on the
housing)
Check the safe function of the safety guard par-
ticularly
f
after any setup work
f
each time after the replacement of an MGB module
f
after an extended period without use
f
after every fault
f
after any change to the DIP switch setting
No servicing is required, repairs to the device are only
allowed to be made by the manufacturer.
