Maintenance
When designing this device, MRDcom 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.
MRDcom is continually working to improve and develop our software. You can
contact our after-sales staff for a new version of the software.
Depending on the degree of pollution in the operating environment, check at
regular intervals that the ventilation slots in the device are not obstructed.
