9.2.1 Daily routine maintenance
Before starting to work:
- Make sure that the symbols on panel on the Transmitting Unit and on the Receiving Unit
are clearly visible and replace the panel if necessary.
- Make sure that the plates on the Transmitting Unit and on the Receiving Unit are readable
and intact (refer to the specic part in the Manual concerning the Transmitting Unit and
the Receiving Unit).
- Make sure that the mechanical operation of the STOP pushbutton is correct.
- Make sure that the Transmitting Unit and the Receiving Unit are whole in all their parts.
- Check the Receiving Unit status and remove any material from it (dust, remnants, object,
etc.): never use solvents or ammable/corrosive materials for cleaning, and do not use
high-pressure water cleaners or steam cleaners.
- Check that the wiring of the Receiving Unit is intact and connected.
During normal operation:
- Do not damage the Transmitting Unit (avoid falls, bumps, contact with water, uids or
liquids, etc.).
- Pay attention not to let materials (by way of example: concrete, sand, grease, dirt, lime,
dust, etc.) deposit on the Transmitting Unit because they can compromise its use and
safety.
After using the Radio Remote Control:
- Clean the Transmitting Unit: never use solvents or ammable/corrosive materials and do
not use water jet cleaners, or air pressure or steam pressure cleaners.
- Store the Transmitting Unit in clean and dry places.
9.2.2 Three-month routine maintenance
At least every three 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 contacts of
STOP relays close. Then, press the STOP pushbutton and check in the Receiving Unit
that the contacts of the STOP relays 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.
