TROUBLESHOOTING
PROBLEM: INFEED CONVEYOR NOT OPERATING USING MANUAL CONTROLS
(ALL OTHER FUNCTIONS WORK)
POSSIBLE CAUSE
SOLUTION
Material wedged or stuck
preventing the discharge belt
from turning.
With the machine shut down, check around the infeed conveyor belt
looking for anything that may have the infeed conveyor belt bound up.
Broken key.
Check and replace broken or damaged motor or shaft keys.
Low hydraulic system pressure.
Check the hydraulic pressure by placing the pressure gauge in the
diagnostic port on the control valve and plugging the hydraulic lines or
raising the infeed all the way to simulate a load. Pull the yoke handle
towards you to check the working pressure. Put the infeed conveyor
manual control valve into forward or reverse position to check the infeed
conveyor working hydraulic pressure. A very low pressure reading
would indicate a hydraulic problem with the pressure relief valve or the
hydraulic pump. See relief valve setting in the hydraulic section.
No hydraulic system pressure
Check to see if any other function on the valve bank works. If another
function works, check the motor. Check the pump.
PROBLEM: INFEED CONVEYOR NOT OPERATING WITH REMOTE OR KEY PAD
(ALL OTHER FUNCTIONS WORK)
POSSIBLE CAUSE
SOLUTION
Bad solenoid on the control
valve.
Check to see if the handle on the valve moves. Swap the solenoid
with the solenoid from a different valve and if the problem follows the
solenoid replace the solenoid.
No electrical signal to the
solenoid on the control valve.
Check for electrical power at the solenoid while engaging the switch
for the infeed conveyor on the radio remote or key pad. A wire may be
broke or have a faulty output. Refer to maintenance screen on control
panel to check that outputs are functional.
Faulty switch in radio remote
control or tether control.
If using the radio remote control, check the maintenance screen on
control panel to check that inputs are functional (Refer to the Bandit
Controls manual).
PROBLEM: DISCHARGE CONVEYOR BELT NOT RUNNING
(ALL OTHER FUNCTIONS WORK)
POSSIBLE CAUSE
SOLUTION
Material wedged or stuck
preventing the discharge belt
from turning.
With the machine shut down, check around discharge conveyor belt
looking for anything that may have the discharge conveyor belt wound
up.
Material wedged in idler drum
causing a high spot.
With the machine shut down, remove any debris trapped in the idler
drum.
Discharge belt conveyor
running off track
Refer to “Adjusting Discharge Conveyor Belt Tracking” on page 39.
Discharge belt conveyor drive
roller spinning inside of belt.
Refer to “Adjusting Discharge Conveyor Belt Tension” on page 60.
Broken drive key.
Check and replace broken or damaged key between motor and drive
shaft.
Bent shaft on drive or idler
drum rollers.
Check both drum rollers and replace if damaged.
No hydraulic system pressure
Check to see if any other function on the valve bank works. If another
function works, check the motor. Check the pump.
