SCHWINTEK INWALL SLIDEOUT SYSTEM TROUBLESHOOTING
(Cont’d)
Error codes
During operation when an error occurs the board will use the led’s to indicate where the problem exists.
For motor specific faults the green led will blink 1 time for motor 1, and 2 times for motor 2. The red led
will blink from 2 to 9 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 1 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.
When an error code is present, the board needs to be re-set. Energizing the extend/retract switch resets
the board. Energize the extend/retract switch again for normal operation.
Checking Fuses
The Schwintek Inwall Slide requires a minimum of 30 amp fuse. Check the 12 volt fuse box for blown
fuses, and replace any if necessary. Consult the RV manufacturers documentation for the location of the
12 volt fuse box, and the locati
on of the Room Slide Controller’s fuse. If the fuse blows immediately upon
replacement, there is a problem with the wiring to the Inwall Slide control box. Have qualified service
personnel check and repair.
Obstructions
Check outside the RV for possible o
bstructions: tree, post, car, etc… Check inside the rv for any
obstructions: luggage, furniture, open cabinets, etc… Also check for smaller objects that may be wedged
under the floor or in the sides of unit. Remove obstructions before proceeding.
Error Codes
Consult rv manufacturer’s documentation for the location of the Inwall Slide Controller. See top of page
for a description of the error codes, and possible problems.
Low Voltage
The Schwintek Inwall Slide Controller is capable of operating the room with as little as 8 volts. But at
these lower voltages the amperage requirement is greater. Check voltage at the controller. If voltage is
lower than 11 volts, it is recommended that the battery be placed on a charger until it is fully charged. It
may be po
ssible to ’jump’ the RV’s battery temporarily to extend or retract the room. Consult the RV
manufacturer’s owner’s manual on the procedure for ‘jumping’ or charging the battery.
