ELECTRICAL SYSTEM
BATTERY STATUS DISPLAY:
The display will show the battery voltage. This display is accurate to /- 0.15 volts. Therefore, the voltage displayed may not correlate precisely to a high-
accuracy, calibrated voltmeter.
OUTPUT CONTROLS:
The control panel switches are used to control various output functions of the main control unit. Below is a list of each switch and the function it controls. Following
the list is a detailed description of each function.
Scrub off Switch
(H)
: Controls brush motor.
Scrub on Switch (I)
: Controls scrub deck lift actuator.
Vacuum Switch (C)
: Controls vacuum motor.
Wand Switch (E)
: Used to jog actuator.
Solution Switch (B)
: Turn on solution pump and solenoid valve.
Extended Scrub Switch (G)
: Turn on recycle pump (If available).
Detergent System Switch (F)
: turn on chemical pump (If available).
Scrub System Off Switch (H):
This switch is used to toggle the state of the brush motor. Pressing and releasing this switch will alternately turn the brush motor on and off. The indicator provides
the following status information:
Off – Brush motor output is off and there is no brush motor current sensed.
Steady Green – Brush motor output is on and there is normal brush motor current sensed.
Brief On Green Flash – Brush motor output is off and brush motor current is being sensed (abnormal condition).
Check for voltage at the Wht wire on K1 contactor to battery ground.
•
If any voltage is present, replace K1 contactor.
•
NO voltage, replace the Main control board.
•
Brief Off Green Flash – Brush motor output is on and brush motor current is not being sensed (abnormal condition).
Check brush motor wiring plugs.
•
Check one of the Blk wires of the main harness connector at the brush motor to battery Positive. If no voltage repair or replace wire.
•
Check one of the Wht wires of the main harness connector at the brush motor to battery Neg. If no voltage repair or replace wire.
•
Check for voltage at the Red wire on K1 contactor to battery ground. If no voltage is present repair the Red wire.
•
Check for voltage at the Wht wire on K1 contactor to battery ground. If no voltage is present replace the K1 contactor.
•
Flashing Red – Brush motor overload has occurred.
Check to see that the proper brush programming type is selected (disc or cyl).
•
Check for binding in rotation of brushes or improper scrub brush type installed. (Amp. Test) See Pressure Chart in this Manual.
•
Check the negative supply cable at the brush motor for a wiring problem or improper modi
fi
cations.
•
Check for open in the small WHT/GRA current sense wire.
•
Check for short circuit* in brush motor or wiring.
•
Inspect gearbox for failure (disc). Repair or replace.
•
Inspect scrub brush drive bearings for excessive wear (cyl.).
