Operating Instructions
Read Heads/Actuators CMS for Safety Relays ESM
Service and inspection
Remove iron swarf from the read head and actuator
at regular intervals.
Use only solvent-free cleaning agents for cleaning
the actuators and read heads.
Regular inspection of the following is necessary
to ensure trouble-free long-term operation:
Correct switching function
f
Secure mounting of components
f
loose connections.
f
In the event of damage or wear, the damaged
system component must be replaced.
Exclusion of liability under the
following circumstances:
Incorrect use
f
Non-compliance with safety regulations
f
Installation and electrical connection not per-
f
formed by authorized personnel
failure to perform functional checks.
