Main Controller Error Codes
Error Description Comments
03 Drive System Fault. The Wheel Drive Controller is reporting an error. See the
Wheel
Drive Controller Error Codes described on page 82
for a list of
error codes.
04 Scrub Deck Lift Actuator
Overload.
The actuator amperage was detected above 6 amps for more than 5
seconds.
• Inspect the scrub deck for obstruction.
• Measure the actuator amperage with and without the scrub deck
connected.
• Raising current = 1.4 to 2.8 amps
• Lowering current = 0.8 to 1.3 Amps
• If the no-load current remains high, then the actuator or wiring is
faulty.
05 Brush Motor Overload The brush motor amperage was detected above 60 amps for greater
than 5 seconds.
• Check the scrub setting adjustments described previously in this
chapter.
• Check for binding in rotation of brushes or improper deck lift
actuator operation.
• Inspect the ground wire supplying the brush motors for poor or
corroded connections. The voltage drop across this wire is used to
measure the amperage to the motors.
• Inspect the current sense wire (Yellow/violet) for continuity.
• Make sure the correct scrub deck is specified in the control board
settings.
06 Squeegee Lift Actuator Overload The actuator amperage was detected above 6 amps for more than 5
seconds.
• Check the Actuator Limit Adjustment described on page 73.
• Inspect the actuator and cable for obstructions to movement.
• Measure the actuator amperage:
• Raising current = 2.2 to 3.4 amps
• Lowering current = 2.2 to 2.6 Amps
07 Vacuum Motor Overload The motor amperage was detected above 25 amps for more than
5 seconds for each motor (Normal current load is 18-20 Amps per
motor.).
• If the optional second vacuum motor is installed, enter the main
machine controller programming and ensure that the Vacuum
Selection is set for 2 vacuum motors.
• Inspect the vacuum motor impeller for obstruction.
• Check the vacuum discharge for obstruction (inlet obstruction will
reduce the amperage).
• Inspect the vacuum motor brushes
• Defective motor bearings.
• Inspect the current sense wire (Brown/Red) for continuity
08 Solution Solenoid Overload The solenoid amperage was detected above 2.4 amps for more than
5 seconds.
• Check for wiring problems on the coil circuit and repair wiring.
• Check resistance on the solenoid coil. If the value is less than 20%
of the values below, replace the contactor/solenoid
• Solution solenoid coil
