Operational faults

FAULT

PROBABLE CAUSE

CONTROL/REMEDY

Area is not being measured.

Boom width or speed constant have not
been entered.

Enter the values in menu [3.3.1 Width] and [3.1 Speed calibration].

Missing speed sensor.

Check the sensor using menu [4.5.2 Speed], check the cable to the
sensor for damage. If necessary, replace the sensor.

Check sensor location [3.1 Speed calibration].

The volume rate L/ha is continuously
displayed at “0”.

Constant has not been entered.

Enter constant in menu [3.2.1 Flow calibration].

Pulses of the flow meter are not reaching
the sprayer control unit.

Check wiring. Check the impeller of the flow meter, using menu [4.5.1
Flow] - it may be stuck.

The volume rate display is not correct.

The flow meter is not working properly.

Test the flow meter using menu [4.5.1 Flow].

The area is not being registered.

Check boom width and adjust if necessary.

Re-calibrate speed [3.1 Speed].

The intended volume rate cannot be
reached.

The volume is below the pre-set rate.

The pressure motor has been wrongly
poled. The rate is controlled downwards
instead of upwards.

Check the control by using the +/- keys in manual mode.

Change the control motor connections if necessary.

The pump cannot deliver the required
amount.

Increase PTO speed. Change to a lower gear.

The filters are blocked.

Clean the filter.

Wrong flow PPU.

Check PPU using menu [3.2 Flow calibration].

The volume rate lies above the pre-set rate. The pressure motor has been wrongly

poled. The rate is controlled downwards
instead of upwards.

Check the control by using the +/- keys in manual mode.

Change the control motor connections if necessary.

The return flow from the pressure motor to
the tank cannot take superfluous quantity.

Check the tube system. Reduce the power of the pump (lower PTO
speed, higher gear).

Volume application rate not stable when
only one or two boom sections are open.

Flow below minimum frequency of flow
transducer.

Set pressure manually when spraying with so sections.

Install a pressure transducer. Under 5 Hz from the flow transducer will
result in the system switching to pressure based sensing for volume
application rate.

Safetrack not responding.

Sensor not reading correctly.

Check menu [4.7 Emergency track] and correct sensor distance, replace
sensor.

No speed signal.

Check sensor using menu [4.5.2 Speed]
