XL2 SLIDE-OUT SERVICE MANUAL
17.3 MOTOR CONTROLLER
The motor controller has 4 LED to show the controller activity and indicate errors (figure 36). The error
LED flashes once every 2 seconds when the controller is in operation. When retracting the slide-out, the
"Motor In" LED comes on, and when extending the slide-out, the "Motor Out" LED comes on. When the
motor is in motion activity, the error LED is disabled. In that state, if a communication error is detected,
the motor is stopped 2 seconds after the detection.
