8 RECEIVING UNIT DIAGNOSTICS
If the system “machine+radio remote control” does not start, check if the problem is caused
by the radio remote control or the machine. Therefore, before carrying out any verification
connect the cable control unit: if the machine does not start, the problem lies with the ma
-
chine itself.
If, on the other hand, the machine only starts using the cable control panel, the problem lies
with the radio remote control. In this case, follow the diagnostics procedure of the transmit
-
ting unit and then proceed as follows:
Is the external
signal light
continuously
switched on?
Is the connecting
plug between the
radio remote control
and the machine
connected
correctly?
Correctly insert
the connecting plug
and start the radio
remote control.
Is the external
signal light blinking?
Remove power from
the receiving unit.
Check fuses. Are
they intact?
Check the power
supply connections.
Carry out the
frequency change
procedure (see
transmitting unit
manual). Does the
machine start?
