Operation Diagnostic Issues
Issue
Possible Cause
Solution
Booms raise but will not
lower when starting the
machine or engaging the
hydraulics (pull-type
sprayers) with AutoBoom
engaged.
PWM base is too high.
Engage the AutoBoom hydraulics and allow the PWM
base to decrease and the booms to lower
automatically.
System is out of calibration. Re-calibrate the AutoBoom system.
(Pull-type only) Restriction
in the tank line.
• Check the quick couplers on the sprayer.
• If the sprayer is equipped with a case drain line
(non-restricted), connect the tank line to this hose.
Booms will not enable with
the down-tap of the
machine functions.
The boom sense adapter
cables are damaged or not
connected.
• Check the cabling.
• Use the Diagnostics screen to help determine the
proper wiring set up.
Inadequate voltage to the
AutoBoom system.
Use a multi-meter to 12 V is provided to the
machine coils when the function is activated.
AutoBoom system is not
calibrated.
Calibrate the AutoBoom system.
AutoBoom harness cable is
damaged.
Inspect the cable for damage and repair or replace as
necessary.
AutoBoom node is faulty.
Replace the AutoBoom node.
The pressure alarm is
always on.
Pressure alarm setting for
PowerGlide Plus mode is
set too low.
Increase pressure alarm setting.
Pressure and tank hoses
are reversed.
Check pressure (P) and tank (T) lines connected to
AutoBoom valve and switch if necessary.
Pressure transducer is
faulty.
• Inspect the transducer and verify the pressure
reading on the Diagnostics screen.
• Replace the pressure transducer if necessary.
The AutoBoom harness
cable is damaged.
Inspect the cable for damage and repair or replace as
needed.
Booms are resting on the
stops or cylinders are fully
extended.
Raise the booms, lower the center section, and re-
engage AutoBoom.
Objects under one boom
makes the opposite side
react.
The inner and outer sensor
connections are reversed.
Check the inner and outer sensor connections and
reverse if necessary.
Proportional valve
connections are reversed
or one side is not
connected.
Check the connections on the AutoBoom valve to
ensure the harness cable connections are inserted
into the correct ports.
Stability setting is too low.
Gradually increase the stability setting until the
opposite side barely reacts to boom movement.
Proportional valve is faulty.
• Inspect the proportional valve.
• Clean and/or replace if necessary.
