Operating Instructions
Read Heads/Actuators CMS for Safety Relay ESM

Maintenance 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 and tear, 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.
