Schwentke Slide-out Maintenance

We are utilizing the Schwentke electric slide-out system in the upstairs portion of the RV, typically a bedroom slide-out. All slide-outs are operated at the central monitor panel shown below. This panel will be found relatively close to the entry door of the RV in a cabinet designed to house this panel. The slide-out system should never be used for anything another purpose other than extending and retracting the slide-out room itself. To use the system for any reason other than what it is designed for may result in death, serious injury or damage to the coach.

Operating Your Schwintek Slide-outs

Extending the Slide-out

1. Level the RV.
2. Verify the battery is fully charged.
3. Press and hold the room’s switch in the “OUT” position until the room is fully extended and stops moving.
4. Release the switch, this will lock the room in the “OUT” position.

Retracting the Slide-out

1. Verify the battery is fully charged.
2. Press and hold the room’s switch in the “IN” position until the room is fully retracted and stops moving.
3. Release the switch, this will lock the room in the “IN” position.

NOTE
It is important to continue to press the slide-out switch for a few seconds after the room is fully extended until the motor shuts off. The control will sense the room has stopped and shut the motor off automatically.

Slide-out Controller Overview

• Status LEDs: 2 LEDs, 1 green and 1 red, are provided to indicate current controller status and faults.
• Mode Button: Used to engage the electronic manual override.
• Power Connection: 12V DC input. Unit will operate from 8V DC to 18V DC.
• Switch Connection: Spade connection for the switch wiring.
• Motor 1 Connector: Power and encoder input for motor 1.
• Motor 2 Connector: Power and encoder input for motor 2.

Slide-out Controller Connections

• Connections & Motor Harness

NOTE: Motor harnesses have Molex connectors at the controller and a molded connector at the motor end (2 images shown above). Wire colors match with color codes on the control board. It does not matter which motor is 1 or 2.

Schwentke Slide-out System Overview

Slide-out Motor and Harnesses

Check for proper connections between the motors and harnesses. Visually inspect the exposed harnesses to ensure they are not pinched or damaged.
Note: Ribs on motor connector lineup with notch inside of female connector on the wiring harness. Color codes on wires also match (black to black, red to red, etc.).

Adjusting / Resynchronizing the Slide-out Motors

1. Run the slide-out room all the way out.
   NOTE: Keep the switch pressed until the motors shut down on their own.
2. Bring the slide-out back in 1-2 inches.
3. Repeat steps 1 and 2 until both motors shut down at the same time.
   NOTE: It can take 3 or more attempts to successfully re-sync the room.
4. Run the slide-out all the way out.
   NOTE: Keep the switch pressed until the motors shut down on their own. Fully retract the slide-out again. When both motors shut down at the same time at full extension and full retraction, the room is properly synchronized. If they do not shut down at the same time, repeat the process until they do.

Schwentke Slide-out Troubleshooting

The slide-out requires a minimum of a 30-amp circuit breaker. Check the 12-volt distribution center for blown circuit breakers and replace any if necessary. If the circuit breaker blows immediately upon replacement, there is a problem with the wiring to slide out the controller. Check outside the RV for obstructions. Check inside the RV for any obstructions. Also, check for smaller objects that may be wedged under the floor or in the sides of the unit. Remove any obstructions that exist. Check the sides of the slide room for any dirt or debris. Small dirt clumps or metal shavings can cause the spur gear to bind up and stop the slide-out from moving. Use an air compressor or a dry brush to remove any dirt or debris from the rack before attempting to use the slide-out again. During operation when an error occurs, the board will use the LEDs to indicate where the problem exists (shown below).

Schwintek Slide-out Troubleshooting

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 2 to 9 times depending on the error code. When an error code is present, the board needs to be reset. Energizing the slide-out switch resets the board. Energize the slide-out switch again for normal operation.

Error Code	Name	Description
2	Battery Drop Out	Battery capacity low enough to drop below 6 volts while running or short in switch wiring
3	Low Battery	Voltage below 8 volts at the start of cycle
4	High Battery	A voltage greater than 18 volts
5	Excessive Motor Current	High amperage, also indicated by 1 side of the slide continually stalling
6	Motor Short Circuit	The motor or wiring to the motor has shorted out
8	Wire Short Between Controller and Motor	The encoder is not providing a signal. This is usually a wiring problem.
9	Hall Power Short to Ground	Power to the encoder has been shorted to ground. This is usually a wiring problem.

Schwintek Slide-out Electronic Manual Override

1. Press the mode button on the controller six times and hold on the seventh for five seconds to enter electronic manual override mode.
2. Use the slide-out switch to move both motors in or out. Note: Over-current and short-circuit detection are still enabled. Electronic manual override provides 12-volt directly to both motors.
3. To exit this mode, push and hold the mode button until the LEDs begin to blink simultaneously. Exiting the override mode resets the motor positions which will require you to have to re-sync the motors. Note: During this override procedure the motors are not synchronized. Visually watch the room, if one side is moving noticeably slower than the other (or not at all) then immediately stop and use the Motor Disengagement Procedure covered below.

Motor Disengagement Procedure

1. Remove retention screws from the motor, located near the top of each vertical column on the outside of the coach.
2. Locate motor.
3. Pull the motor up until disengaged. A flathead screwdriver can be used to pry the motor up.
4. Reinstall the motor retention screw to hold the motor in place or remove the motor.

Slide-out Low Voltage

The slide-out controller can operate the room with as little as 8 volts. However, at these lower voltages, the amperage requirement is greater. Check the voltage at the controller. If the battery is low, it needs to be charged or the unit should be plugged into shore power (or generator), if equipped.

Slide-out Motor Direction Switches

The motor direction switches are used to change the direction of the individual motors. When running the slide-out room in or out and one side goes in and the other side goes out, then there is a problem with the wiring. The motor direction switches can be used to correct this problem. The left switch controls motor 2 and the right switch controls motor 1. If motor 1 is going in the wrong direction, then change switch 1’s position. If motor 2 is going in the wrong direction, change switch 2’s position. The motor direction switches can also be used to change the direction of the slide-out switch. If the room extends when the slide-out switch is moved to the in position, its direction can be reversed by moving both switch 1 and switch 2 to their opposite positions. This feature can be used if it is more convenient to change the motor direction switches than to rewire the slide-out switch.

Schwintek Slide-out Maintenance

Keep the gear racks and seals clean and free of debris. They can be washed with mild soap and water. NOTE: No grease or lubrication is necessary, and in some situations can be detrimental.

After servicing the slide-out system in any way, be sure to check the following:

• Slide-out stops are installed and adjusted properly.
• Head assemblies are installed and adjusted properly.
• The system is mounted properly.
• Cross shafts are mounted properly and clear all other components.
• Gear packs function properly.
• Manual override is accessible.
• Outside seals compress when the slide-out is retracted.
• Inside seals compress when the slide-out is extended.
• Slide-out extends and retracts smoothly.
• Both sides of the slide-out are synchronized.
• Any dirt or debris is cleaned from the interior or exterior of the coach.

Electrical Overview

Your RV has a 12-volt electrical system and a 120-volt system. The 12-volt system is powered by battery and powers items such as the water heater, furnace, and refrigerators, as well as most of the lights. Water pumps, carbon monoxide detectors, and a number of other items will also be powered by the 12-volt system. You will also find that Alliance RV has a conveniently color-coded and numbered 12-volt wiring system. The 120-volt system is powered by an electrical source via your power cord, a generator and in some cases, an inverter (which converts 12 volts to assist in powering the 120-volt system), and typically powers kitchen appliances, TVs, and other electrical appliances. Alliance RV is compliant with industry standards applicable at the time the RV is manufactured. Do not make unauthorized changes.

WARNING
CHANGES OR ADDITIONS MADE AFTER DELIVERY MAY RESULT IN HAZARDOUS CONDITIONS. ALWAYS HAVE A PROFESSIONAL WORK ON YOUR RV.

Modifications to the RV electrical system should only be performed by qualified technicians and should never be made without approval from Alliance RV. Should a modification be made, those changes MUST comply with current safety and code requirements.

WARNING
USE CATION WHEN USING METAL TOOLS. IF A TOOL CONTACTS A BATTERY TERMINAL OR METAL CONNECTED TO IT, A SHORT CIRCUIT COULD OCCUR AND CAUSE INJURY.

Before working on the electrical system

• Make sure the inverter (if equipped), is turned off before disconnecting the batteries.
• Disconnect the power cord.
• Turn off the generator (if equipped) and disable the auto start function (if equipped).
• Turn off the battery disconnect switch.
• Turn off the 120-volt AC main circuit breaker.
• Disconnect the negative 12-volt DC battery terminal from the battery.
