12.1 General Operation
Boom does not appear to be level after system setup:
• The sensitivity setting may be too low. Check the sensor height readings, if it differs from
the target height then try turning up the sensitivity. The default tolerance for a sensitivity
setting of 5 is ± 6 cm (2.5 inches).
• The dead zone may be calibrated incorrectly. If the dead zone is set too low the system
cannot make small corrections. Recalibrate the dead zones as described in Section 8.3.2.
• The sensor offset heights may be incorrect. Refer to Section 8.3.1.
The system will not go into automatic mode:
• Ensure the system has completed an automatic install. If the automatic install was started
and not finished, at least one hydraulic function (Section 8.3.2) will need to be manually
tuned before the system will go into automatic mode.
The system resets when a valve is turned on:
• Check the power supply. The sprayer’s power supply voltage must be more than 12 VDC.
• This may also be caused by a damaged or defective power supply cable. Check the power
cable for a good connection to the supply.
The system randomly switches between auto and manual mode:
• This may be caused by a damaged or defective interface cable. Ensure all cables are
connected correctly. The connections should be tight and free of corrosion.
• There may be electrical noise on the sprayer’s DC system. Add a power line filter or
freewheeling diodes on one or more of the sprayer’s solenoid valves.
