Troubleshooting
Error Codes
During operation when an error occurs, the board will use the LEDs to indicate where the problem exists.
For motor specific faults, the green LED will blink once for Motor 1, and two times for Motor 2. The red LED
will blink from two to nine times, depending on the error code.
The error codes are as follows:
2
Battery drop out:
Battery capacity low enough to drop below 6 volts while running.
3
Low battery:
Voltage below 8 volts at start of cycle.
4
High battery:
Voltage greater than 18 volts.
5
Excessive motor current:
High amperage, also indicated by one side of slide continually stalling.
6
Motor short circuit:
Motor or wiring to motor has shorted out.
8
Hall signal not present:
Encoder is not providing a signal. Usually a wiring problem.
9
Hall power short to ground:
Power to encoder has been shorted to ground. Usually a wiring problem.
In the event of any error code, the unit can be manually overridden electronically using these steps:
1.
Locate the circuit board (brain, controller).
2.
Press the “mode button” six times quickly, press a seventh time and hold for approximately five
seconds.
3.
The red and green LED lights will begin to flash indicating you are in override mode.
4.
Using the wall switch, press and hold the “in” button until the unit comes completely in.
NoTE:
The "8" error code is the most common. This can signify one of these issues:
•
Pinched or broken wiring in the system harness or motor pigtail.
•
Disconnected or faulty motor.
NoTE:
The "9" error code signifies a short in the red or black wire on the motor. Replace the motor.
Checking Fuses
Check the 12 volt fuse box for blown fuses, and replace any if necessary. If the fuse blows immediately upon
replacement, there is a problem with the wiring to the circuit board. Have qualified service personnel check
and repair.
Obstructions
Check outside the RV for possible obstructions: tree, post, car, folded over flap seals, debris on top of the
slide room, etc. Check inside the RV for any obstructions: luggage, furniture, open cabinets, carpeting,
etc. Also check for smaller objects that may be wedged under the floor or in the sides of unit. Remove
obstructions before proceeding.
