User's Manual

ROUTINE MAINTENANCE
The following instructions allow to maintain the radio remote control in a perfect condition,
guaranteeing it to function safely and correctly for a long period.
Special applications may need more specific routine maintenance interventions to be carried
out at different periods.
These instructions do not in any case substitute the norms and laws that regulate work
safety, 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 radio
remote control are started.
!
If irregularities are noted while carrying out routine maintenance, put
the "machine+radio remote control" system out of order, following the
indications given (see “Receiving unit diagnostic”)

It is recommended every three months to:
1. remove dust or accumulations of other material from the receiving unit. Never use solvents
or flammable/corrosive materials to clean, and do not use high pressure water cleaners or
steam cleaners.
2. make sure that the receiving unit are structurally integral
3. verify the integrity and connection of the internal wiring to the receiving unit

Electrical operation
It is recommended every six months to:
1. make sure that all the relay contacts of the receiving unit operate correctly, controlling
contact closing when the corresponding manoeuvre is enabled and contact opening when
the manoeuvre is disabled.
2. verify the correct correspondence between the commands that are sent and the
manoeuvres that are carried out.
3. verify that the contact for the SAFETY relay is open when no movement command has
been sent.
External electric conductors
It is recommended every twelve months to:
1. verify integrity along the full length of the cable which connects the receiving unit to the
machine.
2. verify the integrity and the electrical connection of the plugs and the connection socket
3. verify and if necessary replace the strips or other fixing systems
4. make sure that the connecting cable has not deteriorated, above all near the cable holder
