Safety Information and Maintenance
(Part of the Operating Instructions for Safety Switch CET-AR/CET-AP)
Inspection and service
Warning! Loss of the safety function because of
damage to the system.
In case of damage, the related component 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
f
Check the secure fastening of the devices and
f
the connections
Check for soiling
f
Check the safe function of the safety guard par-
ticularly
after any setup work
f
after the replacement of a CET component
f
after an extended period without use
f
after every fault
f
No servicing is required, repairs to the device are
only allowed to be made by the manufacturer.
