6. TROUBLESHOOTING
The sensor mounted on the feed rotor clutch ram prevents
conveyor operation if the feed rotor is not engaged.
The photograph opposite shows the position of the clutch
ram when the feed rotor is rotating.
It is essential that the clutch ram rod is fully retracted for
the circuit breaker sensor to be activated.
Problem
What to do
l
Insufficient grab power
- Check that the hydraulic connections between the
tractor and the machine are correct (pressure and
return).
- Check the hydraulic pressure (190 bar) and the pump
output (35 l/min). The return pressure must be 8 bar
maximum at the nominal tractor speed.
l
Hydraulic functions fail
- Check that the hoses are correctly connected to the
to operate
tractor distributor (make sure that the valves are opening
as dirt can hinder correct operation).
- Make sure that the voltage provided by the battery is over
11 V.
- Check that the original tractor distributor is set to the
continuous pumping position (except with auxiliary
hydraulic unit).
- Check that the control unit is switched to 1 or 2.
- Check that the control unit power cable is plugged in.
- Check that the battery power is reaching the socket.
- Check the polarity of the socket.
l
The conveyor fails to run
- Check that the feed rotor is engaged and the indicator is
lit (see section 1.6 Description of the Controls).
- Open the left-hand side hood and check that the belt
tension roller ram rod is fully retracted.
- Check that the circuit breaker sensor on the feed rotor
clutch is activated.
