13
Solution control pump overload
•
The normal current load is 0.8-1.8
amps.
•
A current load of 3.2 amps or over
will generate code 13 pump motor
overload.
1. Check for short circuits* in the wiring and in the
M12
pump motor.
2. Disconnect the solution pump motor and run the
machine to see if the wiring is shorted.
3. Check the current draw and compare to the
specifications. If the motor shows high current draw
replace the motor.
16
K6
Side broom motor contactor coil
overload
The nominal coil resistance is 100
ohms.
1. Check for a
K6
coil wiring problem or short circuit*
(wire colors VIO and BRN/BLK).
2. Check the coil resistance. If the resistance is below
80 ohms, replace the contactor.
17
Side broom actuator overload
•
Normal current load is 1-2 amps.
•
Max current load is 6 amps.
•
Max current with no load is 1.4
amps.
1. Check for binding or frozen side broom lift linkage and
excessive weight on the lifting arms.
2. Check for a short circuit* in the actuator motor and
wiring. Repair or replace.
To test the actuator, disconnect the motor plug and
attach the actuator power cord adapter (p/n 56407502)
and perform an amp draw test. Compare readings to the
current load specifications.
18
K5
Auxiliary contactor coil overload
The nominal coil resistance is 100
ohms.
1. Check for a
K5
coil wiring problem or short circuit*
(wire colors YEL/BRN & BLK/ORN).
2. Check the coil resistance. If the resistance is below
80 ohms, replace the contactor.
19
Back-up alarm overload
Specifications:
•
5-15 VDC
•
Current load 100 ma
1. Check for a back-up alarm wiring problem or short
circuit* (wire colors: positive ORN/BRN; negative
BLU/WHT).
2. Disconnect the back-up alarm and test to see if the
wiring is shorted. If not, replace the back-up alarm.
20
Horn output fault
Current load spec. 1.2 amps
1. The horn or horn wiring’s +36V power feed is shorted
to ground (wire colors VIO and BLU/RED).
2. Disconnect the horn and test to see if the wiring is
shorted. If not, replace the horn.
21
Scrub motor open
1. Check for an open circuit in the motor wiring or for a
defective motor.
2. Check for 36 volts at the scrub motor that is not
running. If you get 0 Volts, replace the brush motor
contactor.
22
Left brush motor contactor coil open
1. Check for an open circuit in the
K4
coil and wiring
(wire colors VIO and GRA/RED).
2. Test for 36V at the
K4
coil. If you get 0 Volts, check
the A2 control board assembly.
