Inspection and service
WARNING
Loss of the safety function because of damage
to the system.
In case of damage, the affected module must be
replaced completely. Only accessories or spare
parts that can be ordered from EUCHNER may
be replaced.
Regular inspection of the following is necessary to
ensure trouble-free long-term operation:
 Check the switching function
 Check the secure fastening of the devices and
the connections
 Check for soiling
Check the safe function of the safety guard par-
ticularly
 after any setup work
 after the replacement of a system component
 after an extended period without use
 after every fault
 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.
