AUTEC - Air series
5.4.3 Three-month routine maintenance
Every three months:
- remove dust or deposit of material from the receiving unit: never use solvents or ammable/
corrosive materials to clean it, and do not use high-pressure water cleaners or steam
cleaners
- check structural integrity of the receiving unit
- make sure that the wiring of the receiving unit is intact and connected
- make sure that the receiving unit panel symbols can be easily recognised and replace
the panel if necessary
- check that the plates on the receiving unit are readable and intact.
5.4.4 Six-month routine maintenance
Every six months:
- check the correct correspondence between the commands that are sent and the
manoeuvres that are carried out by the machine
- check that the contact of the SAFETY relay is open when no movement command has
been sent. This is safety critical maintenance: it is necessary to keep a record (date,
signature, comments) showing that this check has been regularly carried out. Keep the
record together with other installation documents.
- make sure that all the relay contacts of the receiving unit operate correctly, and check
that the contact closes when the corresponding manoeuvre is enabled and opens when
the manoeuvre is disabled.
- start up the radio remote control and check in the receiving unit that the STOP relay
contacts close. Then, press the STOP pushbutton and check in the receiving unit that
the STOP relay contacts open.
Before testing the STOP relays, make sure that no dangerous situations may
arise due to the closing of the STOP relay contacts of the receiving unit.
