5 WARNINGS FOR MAINTENANCE
ALWAYS ENSURE THAT THE RECEIVING UNIT HAS BEEN DISCONNECTED
FROM THE POWER SOURCE BEFORE CARRYING OUT ANY MAINTENANCE
WORK.
All control and maintenance actions carried out on the radio remote control must be verified
and recorded by the person in charge of carrying out maintenance on the machine.
Routine maintenance carried out as described in this manual is fundamental
for using the radio remote control safely.
After each maintenance action, always make sure that commands sent by the
transmitting unit only activate the corresponding expected operations.
5.1 ROUTINE MAINTENANCE
The following instructions allow to maintain the radio remote control in perfect conditions,
guaranteeing it to function safely and correctly for a long period.
Special applications may need more specific routine maintenance actions to be carried out
at different periods.
These instructions do not in any case substitute the norms and laws that regulate work safe-
ty, nor do they limit the responsibility of the purchaser and user of the radio remote control.
All given instructions must be followed correctly each time the machine and the ra-
dio remote control are put into service.
If irregularities are noted while carrying out routine maintenance, put the “ma-
chine+radio remote control” system out of order, following the indications giv-
en (see paragraph 8 "Receiving unit diagnostics").
Receiving unit
It is recommended every three months to:
1. remove dust or accumulations of other material from the receiving unit. Never use sol-
vents or flammable/corrosive materials to clean, and do not use high pressure water clean-
ers or steam cleaners
2. make sure that the receiving unit is intact in its structure
3. verify the integrity and connection of the internal wiring to the receiving unit
4. make sure that the panel symbols can be easily recognized and replace the panel if nec-
essary
5. check that the identification plate is readable and not damaged.
Electrical operation
It is recommended every six months to:
1. 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
2. check the correct correspondence between the commands that are sent and the ma-
noeuvres that are carried out
3. check that the contact for the SAFETY relay is open when no movement command has
been sent. This is safety critical maintenance: it’s necessary to keep a record (date, signa
-
ture, comments) showing that this check has been performed regularly, together with other
installation documents.
