Lippert Level-Up Manual

System

Failure to act in accordance with the following may result in serious personal injury or death.
The use of the Lippert Level-Up Motorhome Leveling System for Winnebago Industries to support the coach for any reason other than which it is intended is prohibited by Lippert's Limited Warranty. The Lippert Level-Up Motorhome Leveling System for Winnebago Industries is designed as a leveling system only and should not be used to provide service for any reason under the coach, such as changing tires or servicing the leveling system.
Lippert Components, Inc. recommends that a trained professional be employed to change the tires on the coach. Any attempts to change tires or perform other service while coach is supported by the Lippert Level-Up Motorhome Leveling System for Winnebago Industries could result in damage to the motorhome and/or cause serious injury or death.

1. Be sure to park the coach on solid, level ground.
2. Clear all jack landing locations of debris and obstructions. Locations should also be free of depressions.
3. When parking the coach on extremely soft surfaces, utilize load distribution pads under each jack.
4. People and pets should be clear of coach while operating leveling system.
5. Be sure to keep hands and other body parts clear of fluid leaks. Oil leaks in the Lippert Level-Up Motorhome Leveling System for Winnebago Industries may be under high pressure and can cause serious skin penetrating injuries.
6. Never lift the coach completely off the ground. Lifting the coach so the wheels are not touching the ground will create an unstable and unsafe condition.

Prior to Operation

The leveling system should only be operated under the following conditions:

1. The coach is parked on a reasonably level surface.
2. The coach "PARKING BRAKE" is engaged.
3. The coach transmission should be in the neutral or park position.
4. Be sure all persons, pets and property are clear of the coach while Lippert Level-Up Motorhome Leveling System for Winnebago Industries is in operation.

After starting the automatic leveling cycle it is very important that you do not move around in the coach until the unit is level and the green LED light illuminates in the center of the touch pad. Failure to remain still during the leveling cycle could have an effect on the performance of the leveling system.

Maintenance

Fluid Recommendation

The Lippert Level-Up Motorhome Leveling System for Winnebago Industries is pre-filled, primed and ready to operate direct from Winnebago Industries:
PetroBlend (Mason City, IA), PHO 0022S (group 3 base blend).
NOTE: In colder temperatures (less than 10°F) the jacks may extend and retract slowly due to the fluid's molecular nature. For cold weather operation, fluid specially formulated for low temperatures may be desirable. Contact your manufacturer for recommended fluid.

Preventative Maintenance

1. Check fluid in reservoir every 12 months. If fluid is a clear, red color, do not change. If fluid is milky, pink and murky, and not clear red in color, drain reservoir and add new fluid.
   NOTE: Check fluid only when all jacks are fully retracted.
   NOTE: When checking fluid level, fill to within ¼ to ½ inch of fill spout.
2. Inspect and clean all Power Unit electrical connections every 12 months. If corrosion is evident, spray unit with lubricant.
3. Remove dirt and road debris from jacks as needed.
   
   The coach should be supported at both front and rear axles with jack stands before working underneath. Failure to do so may result in death or personal injury.
4. If jacks are down for extended periods, it is recommended to spray exposed leveling jack rods with a silicone lubricant every three months for protection. If the coach is located in a salty environment, it is recommended to spray the rods every four to six weeks. NOTE: OEM to install attachment brackets for leveling jacks.

Level Zero Point Calibration

Before auto-leveling features are available, the Level Zero Point must be set. This is the point to which the system will return when an auto leveling cycle is initiated.
To set the Zero Point (controller module must be fully secured in production-intent location), first run a manual leveling sequence to get the vehicle to the desired level point. Then activate the Level Zero Point configuration mode.
This mode is enabled by performing the following sequence:

1. Turn panel off.
2. Perform the following:
3. Press the "FRONT" button (Fig. 5H) 5 times.
4. Press the "REAR" button (Fig. 5I) 5 times.
5. At this point, an alarm will sound and the display will read "**ZERO POINT CALIBRATION**" ENTER to Set, POWER to Exit."
6. Press ENTER (Fig. 5C) to set the Zero Point.
7. Screen will then display "PLEASE WAIT".
8. Alarm will sound and the screen will display "ZERO POINT SUCCESSFUL".
9. Control will then turn "OFF".
   For DIESEL UNITS with Air Bag Suspensions ONLY:
   NOTE: The leveling control will automatically program for air bag control. The option will not be present if no dump valve coil resistance is detected.

Error Mode

1. If an error occurs before or during operation, the error will be displayed in the LCD and an alarm will sound. To reset common ERROR displays, press ENTER (Fig. 5C).
   NOTE: To reset "Return for Service" errors, press "ENTER" (Fig. 5C) and "RETRACT" (Fig. 5D) simultaneously.
2. All normal functions will be disabled when the system is in error mode.
3. Auto level can only commence if running voltage is 12.75V DC or above.
4. Auto level operation will halt if running voltage drops to 9.5V DC.
5. Manual level operation can be performed at all running voltages above 9.5V DC.

Excess Slope

1. The control will not operate at extreme slopes, i.e. 3.5° fore and aft and 3.5° side to side.
2. If the coach indicates "EXCESS ANGLE" or "OUT OF STROKE " during an auto level cycle, move the coach to a more level spot.

User Alarm Mode

If the alarm system detects that the park brake has been disengaged while at least one jack is not fully retracted and the sensor value changes in any axis more than a predefined amount, the panel will signal this error to the user. The system performs an automatic retract.
No other features are available in this mode.

Miscellaneous

1. The leveling system will automatically shut off after being idle for 4 minutes.
2. A "Re-level" feature is programmed into the Rev G controller. If the jacks are extended and the user presses Auto Level again the system will re-level from that point. The system will not retract before performing the Re-Level.
3. System will refuse any operation when a low voltage condition is present.
4. System will automatically alarm and retract if park brake is disengaged and jacks are not retracted with any change in sensor readings. In alarm mode, the only available feature is to retract all jacks.

Low Voltage Signal

1. The vehicle requires 12.75V DC to operate in the AUTO mode. If the voltage is too low, the screen will display "LOW VOLTAGE".
2. Minimum Voltage - If voltage drops below 9.5V DC during AUTO or MANUAL operation, "LOW VOLTAGE" will appear in the screen and the system will cease operating.
   NOTE: Coach will operate in manual mode between 9.5V DC and 12.75V DC.

Operation

Selecting A Site

When the coach is parked on an excessive slope the leveling requirements may exceed the jack lift stroke capability. If the coach is parked on an excessive slope, the coach should be moved to a more level surface before the leveling system is deployed.
"EXCESS ANGLE" will appear on the LCD screen if the coach is 3.5° out of level front to rear or side to side. See error code chart.

Automatic Leveling Procedure

NOTE: Refer to Component Description (Fig. 5) for questions regarding location and functions of the Lippert Level-Up Motorhome Leveling System for Winnebago Industries system.
NOTE: Coach must be running and parking brake must be engaged for Lippert Level-Up Motorhome Leveling System for Winnebago Industries to operate.

1. Press "ON/OFF" button to turn system "ON" (Fig. 5K).
2. Press "AUTO LEVEL" button (Fig. 5F). LCD Screen will display "REMAIN STILL".
3. The coach will level automatically and indicate "Auto Level - SUCCESS!" in LCD display (Fig. 5E).
   NOTE: Display will then read "LEVEL - Jacks: Down". Do not press any buttons until this message appears or a "FUNCTION ABORTED" error will be displayed.
   NOTE: Always check to make sure all jacks are fully retracted before travel.

Automatic Leveling Descriptive Logic

Grounding: Steps 1 - 7 describe the process of how the AUTO LEVEL LOGIC extends the jacks to the ground:

1. Depending on which end of the coach is lowest to the ground the level sensor in the controller will activate the jacks, one at a time on the lowest end first, either front or rear.
2. Ground lowest side jack first; i.e., front passenger side.
3. Ground remaining side jack next; i.e., front driver side.
4. Together, both jacks will lift lowest end until level; i.e., front of coach will lift briefly until the coach is level.
5. The system will then ground remaining jacks, one at a time; i.e., rear jacks.
6. Ground lowest side jack first; i.e., rear passenger side.
7. Ground remaining side jack next; i.e., rear driver side.
   Leveling: Steps 8- 11 describe the process of how the AUTO LEVEL LOGIC levels the coach once the jacks have been grounded. This process may repeat several times until level.
8. Fore/aft
9. Side/side
10. Individual
11. Minor adjustments to limit/prevent twist

After starting the automatic leveling cycle it is very important that you do not move around in the coach until the unit is level and the green LED light illuminates in the center of the touch pad. Failure to remain still during the leveling cycle could have an effect on the performance of the leveling system.

Manual Leveling Procedure

NOTE: When leveling your coach the coach should be leveled from front to rear first. When the coach is level from front to rear, then level the coach from left to right.
NOTE: Coach requires 12.75 VDC to commence auto leveling function. If voltage at the power unit is not 12.75 VDC, run the engine.

1. Apply parking brake.
2. Turn ignition "On".
3. Press "ON/OFF" button (Fig. 5K) to turn system "ON".
4. Press "UP" or "DOWN" button (Fig. 5A/B) to scroll through features to "MANUAL MODE" in display.
5. Press "ENTER" (Fig. 5C).
6. Press "FRONT" button (Fig. 5H) to extend front jacks to the ground; Press "REAR" button (Fig. 5I) to run rear jacks to ground and level the coach front to back.
7. Press appropriate "LEFT" or "RIGHT" button to level the coach from side to side. Red flashing lights next to the buttons on touch pad will indicate which side(s) of the coach needs to be raised to achieve level condition.
   NOTE: Jacks always work in pairs, i.e., "FRONT" button operates both front jacks, etc.
   NOTE: The right and left jacks are used to level the coach side to side. Pressing the LEFT button (Fig. 5G) on the control panel will extend both left jacks. Pressing the RIGHT button (Fig. 5J) on the control panel will extend both right jacks. Jacks always work in pairs, both front jacks; both right side jacks, etc.
8. Repeat steps 2 through 7 as needed.
9. Turn power off to leveling system by Pressing ON/OFF button (Fig. 5K).
10. Visually inspect all jacks to ensure all footpads are touching the ground. Should one of the rear jack footpads not be touching the ground, press the corresponding LEFT or RIGHT arrow buttons to lower the non-compliant jack to the ground.

NEVER LIFT ALL THE WHEELS OFF THE GROUND TO LEVEL THE COACH!
Lifting all the wheels off the ground may result in death or serious personal injury.

Jack Retract Procedures

1. Energize the system by pressing ON/OFF button (Fig. 5K) on control panel. The LCD screen will display READY Jacks: Down".
2. Press "DOWN" button (Fig. 5B) to display "Auto Retract All" on the screen.
3. Press "ENTER" (Fig. 5C) to begin.
   NOTE: If the need to stop the jacks from retracting arises, turn the system off and back on again by pressing the "ON/OFF" button (Fig. 5K) twice. The coach can then be manually leveled by following steps 1-9 in the MANUAL LEVELING PROCEDURE section. Press "ENTER" to acknowledge.
4. The jacks will retract and shut off automatically; the display will read "READY - Jacks: Up". Press the "ON/OFF" button (Fig. 5K) on the Control Panel to de-energize the system. After a brief visual inspection around the coach to verify the jacks are fully retracted, you may proceed to travel.
5. To retract in the MANUAL mode, press the "RETRACT" button (Fig. 5D) until it lights. By pressing any of the JACK buttons, the jacks will retract in pairs, i.e. "FRONT" button, both front jacks will retract, etc.
   NOTE: Prior to allowing manual retract functions, the air bags will fill. There will be a 22 second countdown on the LCD display while the air bag fill occurs.
6. "AUTO RETRACT" can also be commenced by pressing and holding the "RETRACT" button (Fig. 5D) for 1 second.
   NOTE: Always check to make sure all jacks are fully retracted before travel.

After jacks are completely retracted, press ROCKER SWITCH and release in the LEVEL (Fig. 6A) position.

Manual Override - Jacks

In the event that the jacks will not extend or retract, the valves can be manually overridden. By using a 5/32" hex wrench to turn the manual override clockwise on the valve, (Fig. 7), the leveling jacks can then be extended or retracted. Remember to turn the manual override completely counterclockwise, (Fig. 8), until it will no longer turn, to close the valve after the jacks have been completely extended or retracted. Do not overtighten override set screws, as this can damage the valves.

Clockwise for manual override

Counterclockwise for normal operation

Manual Override - Power System

The Lippert Level-Up Motorhome Leveling System for Winnebago Industries can be run with auxiliary power devices like cordless or power drills. In the event of electrical or system failure, this manual method of extending and retracting the jacks can be used. A standard handheld drill is all that is required. See the instructions below.

Automatic Safety Shutoff

If the control panel is left on and inactive for four minutes it will shut off automatically. To reset the system, the coach ignition must be turned off, then back on, and the ON/OFF button (Fig. 5K) must again be pressed.

Drive Away Protection System

If the ignition is in the "RUN" position, jacks are down, and the operator releases the parking brake, all indicator lights will flash and the alarm beeper will activate. The system will then automatically retract the jacks until the jacks are fully retracted or the operator resets the parking brake.

Jacks Up Verification

If the ignition is in the "RUN" position, the parking brake is released, and the vehicle is in motion, the system may activate the power unit to ensure that the retract pressure is high enough to keep the jacks fully retracted. The LCD screen will say "JACKS UP VERIFICATION" until the retract pressure has returned to normal. If the touch pad was previously off, the touch pad will shut off again. No beeping will occur and the "JACKS DOWN" dash light will not illuminate.
