4 Maintenance and service

When designing this device, Hirschmann was largely able to forego using
parts that are subject to wear and tear. The parts subject to wear are
designed to last longer than the lifetime of the product when it is operated
properly. Operate this device according to the specifications (see
“Technical data” ).

Relays are subject to natural wear. This wear depends on the frequency
of the switching operations. Check the resistance of the closed relay
contacts and the switching function depending on the frequency of the
switching operations.

Hirschmann is continually working to improve and develop our software.
You should regularly check whether there is a new version of the software
that provides you with additional benefits. You will find software
information and downloads on the product pages of the Hirschmann
website.

Depending on the degree of pollution in the operating environment, check
at regular intervals that the ventilation slots in the device are not
obstructed.
