Fluid Recommendation
The Lippert Electronic Leveling System is pre-filled, primed and ready to operate direct from the manufacturer. Type “A” Automatic Transmission Fluid (ATF) is utilized and will work. ATF with Dexron III® or Mercon 5® or a blend of both is recommended by Lippert. 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. For a list of approved fluid specifications, see TI-188.

Component Description

The Lippert Electronic Leveling System consists of the following major components:

• Lippert jacks are rated at a lifting capacity appropriate for your coach. Each jack has a 9” diameter (63.5 Square inch) shoe on a ball swivel for maximum surface contact on all surfaces. (12” Dia. – 113 Sq. In. shoe also available).
• Each jack is powered from a central 12V DC (Fig.1) motor/pump assembly, which also includes the hydraulic oil reservoir tank, control valve manifold, and solenoid valves.
• The Lippert Electronic Leveling System is controlled electronically from the driver’s seat of the coach. The touchpad is mounted in the dash. The system can be operated in a manual mode or a fully automatic mode.

Power Unit Components

Prior to Operation

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

1. The coach is parked on a reasonably level surface, engine running.
2. The coach “parking brake” is engaged.
3. All jack landing locations are cleared of debris and obstructions.
4. The coach transmission should be in the park position.
5. Locations should also be free of depressions.
   NOTE: When parking the coach on extremely soft surfaces, utilize load distribution pads under each jack.
6. People and pets should be clear of coach while operating leveling system.
7. Be sure to keep hands and other body parts clear of fluid leaks. Oil leaks in the Lippert Leveling System may be under high pressure and can cause serious skin penetrating injuries.
8. Never lift the coach completely off the ground. Lifting the coach so the wheels are not touching ground will create an unstable and unsafe condition.

Operation

Selecting a Site

• Make sure jacks are retracted before attempting to auto level. (The System will perform full retract automatically if jacks are not down on the request of an auto cycle).
• System will refuse any operation when a low voltage condition is present.
• System will automatically alarm and retract if park brake is disengaged and jacks are not retracted with any change in sensor readings.

When in alarm mode, the only available feature is to retract all jacks.

• The LEDs blink differently when in special controller modes (error, alarm and configuration). Learning how to recognize these modes is important.
• Excess slope LED blinks whenever the Y axis (vehicle length) is over 5 degrees from programmed level point.

Touchpad Operation

Automatic Leveling Procedure
Refer to (Fig. 2) for questions regarding location and functions of the Lippert Electronic Leveling System. Coach must be running and parking brake must be engaged for LCI Electronic Leveling System to operate.

1. Push ON/OFF (Fig. 2N) button on touchpad. The system is now operational and the electronic level lights will become active.
2. Check to see that the touchpad ENGAGE PARK BRAKE (Fig. 2H) light is not flashing.
3. Push the AUTO (Fig. 2C) button to begin the automatic leveling cycle.
   NOTE: After starting the automatic leveling cycle it is very important that you do not move around in the coach until the coach is level. This could have an affect on the performance of the leveling system.
4. If further adjustments are necessary, refer to the Manual Leveling Procedures section.
5. Push power button to turn off the system.
6. Visually inspect all jacks to ensure all shoes are touching ground. Should one of the rear jack shoes not be touching the ground. Push the corresponding LEFT (Fig. 2K) or RIGHT (Fig. 2L) buttons to lower the corresponding jack to the ground.

Manual Leveling Procedures
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. Coach must be running for LCI Electronic Leveling System to operate.

1. Push ON/OFF (Fig. 2N) button on touchpad. The system is now operational, ON/OFF light will be lit.
2. Push and hold MAN (Fig. 2A) button for 5 seconds.
3. Push FRONT (Fig. 2J) button until jacks contact the ground and lift the front of the coach 1-2 inches.
4. Push REAR (Fig. 2M) button until jacks contact the ground and lift rear of coach.
5. Press FRONT (Fig. 2J) or REAR (Fig. 2M) button; if light is on at the FRONT button press the FRONT (Fig. 2J) button; if the light is on at REAR button press the REAR (Fig. 2M) button. Continue to hold until the light goes out.
6. Push LEFT (Fig. 2K) or RIGHT (Fig. 2L) button: If light is on at RIGHT button, push RIGHT button; if the light is on at LEFT button push LEFT button. Continue to hold until the light goes out.
7. The right and left jacks are used to level the coach side to side. Pushing the LEFT button on the touchpad will extend both left jacks. Pushing the RIGHT button on the touchpad will extend both right jacks. Jacks always work in pairs, both front jacks; both right side jacks, etc.
8. Repeat steps 2 through 6 if needed.
9. Turn power off to leveling system by pushing ON/OFF (Fig. 2N) button.
10. Visually inspect all jacks to ensure all shoes are touching ground. Should one of the rear jack shoes not be touching the ground, press the corresponding LEFT (Fig. 2K) or RIGHT (Fig. 2L) rear jack buttons to lower the corresponding jack to the ground.

WARNING
Lifting all wheels off the ground may result in serious personal injury or death.

Jack Retract Procedures

1. Energize the system by pushing ON/OFF (Fig. 3A) button on touchpad. The ON/OFF light (Fig. 3E) will be lit.
2. Push the RETRACT ALL JACKS (Fig. 3D) button. All the jacks will start to retract and return to the full retract position. When jacks return to full retract position the JACKS DOWN (Fig. 3G) light will go out.
   If you wish to stop the jacks from retracting, turn the system off and back on again by pushing the ON/OFF button twice. You can then re-level the coach by following steps 1-6 again.
3. When the JACKS DOWN (Fig. 3G) light goes out, push the ON/OFF (Fig. 3A) button on the touchpad 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.

When in the MANUAL mode, if the RETRACT button is pushed the jacks will only retract as long as the RETRACT button is depressed. In AUTOMATIC mode, the RETRACT button need only be pressed once and released for the jacks to fully retract.

Troubleshooting

Automatic Safety Shutoff
If the touchpad 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 must again be pushed.

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. The power unit will also operate to keep the jacks retracted in the event the leveling system loses pressure as the coach is being driven.

Error Mode
If any problem is detected with the jacks, the system will enter Error Mode. Error mode may be recognized by the blinking of Left, Center LCI and Right LEDs. The following errors are detected by this system:

• Jack over current/short circuit.
• Jack under current/ open circuit.
• Jack extending too long (ground not detected after 2 minutes).
• Jack retracting too long (fully retracted not detected after 2 minutes).
• Out of stroke detection during auto cycle (if enabled).

The user must respond by pressing On/Off switch, which resets operation. All normal features are disabled in Error Mode. If panel loses communication with the controller for more than 5 seconds, the panel will blink the Jacks Down, Park Brake and ON/OFF (if included) LEDs.

Level Zero Point Calibration
The Zero Point is the programmed point that the coach will return to each time the Auto Level feature is used. The Zero Point must be programmed prior to using the Auto Level feature to ensure the proper operation of the system. To set the zero point, the control module must be fully secured in the production intent location. Activate the Level Zero point configuration mode by following the steps below:

1. Turn system on by pressing the “ON/OFF” (Fig. 3A). The “ON/OFF” indicator light (Fig. 3E) will illuminate.
2. Press the “MAN” (Fig. 3B) and hold for 2-3 seconds. The indicator light below the “MAN” button will then illuminate. This will put the system into “MANUAL” mode.
3. Level the coach in “MANUAL” mode by using a carpenter’s level on the floor. Level front to rear and then left to right.
   • Push the “FRONT” (Fig. 3C) button until both front jacks contact the ground and lift the front of the coach 1-2 inches.
   •  Push “REAR” (Fig. 3H) button until both rear jacks contact the ground and lift rear of coach. Keep button depressed until the carpenter’s level bubble is centered.
   • Push “LEFT” (Fig. 3F) and “RIGHT” (Fig. 3I) buttons as needed to raise the left and right sides of the coach respectively until level bubble is centered.
4. Turn Touch Pad “OFF” (Fig. 3A) to exit “MANUAL” mode; then turn it on again.
5.  Now that the coach is leveled, press “FRONT” (Fig. 3C) 5 times.
6. Press “REAR” (Fig. 3H) 5 times. At this time all lights on the touch pad will flash with the exception of the ON/OFF indicator (Fig. 3E), it will remain solidly lit.
7. The touch pad is now in zero mode.
8. With the coach in level condition, simultaneously press the “RETRACT ALL JACKS” (Fig. 3D) button and the “AUTO” (Fig. 3J) button to store this as the Zero Level Point reference.
9. The “WAIT” light (Fig. 3K) will flash for approximately 5 seconds. After this, the control will emit an audible beep and revert back to normal operation mode. Zero Point calibration is now complete.

NOTE: You may also enter zero mode per above at anytime the system is in IDLE mode. The user then has control to extend any pair of jacks while in zero mode in order to position the vehicle properly prior to setting the zero point.

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” or 5/64″ hex wrench to turn the manual override clockwise on the valve. (Fig. 4). The leveling jacks can then be extended or retracted. Remember to turn the manual override completely counterclockwise (Fig. 5) until it will no longer turn, to close the valve after the jacks have been completely extended or retracted.

Manual Override – Power System
The Lippert Electronic Leveling System can be run with auxiliary power devices like electric drills, ratchet wrenches or cordless screwdrivers. 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.

1. Remove plastic cap (Fig. 6A).
2. Disconnect power cables on the motor.
3. Using a 1/2” socket, insert into auxiliary drive device, i.e. cordless or power drill. Insert socket onto coupler found under plastic cap (Fig. 7A).
4. Run drill in reverse or counterclockwise to retract jacks.

“Jacks Down” Alarm
The Lippert Electronic Leveling System is designed to sound an alarm and illuminate the control panel in the event of two (2) possible scenarios:

• A “RETRACT” hose leaks.
• The pressure holding the jacks in the retracted position falls to approximately 1500 psi to sound the alarm.

If the alarm sounds and the touchpad illuminates and flash while driving the vehicle:

1. Immediately find an area to safely pull the vehicle off of the roadway.
2. Set the PARKING BRAKE.
3. Inspect all jacks hoses and check valve for leaks.

If no leaks are observed;

1. Turn touchpad “ON.”
2. Push “RETRACT ALL JACKS” button.
3. Wait until “JACKS DOWN” light and alarm are off.
4. Inspect jacks. If jacks are retracted and no leaks are observed, vehicle can be driven.

If system is leaking or alarm does not subside after applying the above procedure, disconnect wires from pressure switch and proceed immediately to a service center. For prolonged travel to the service center, be sure to stop and check the disposition of the leveling jacks periodically to make sure they are not extending.

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. When in alarm mode, all LEDs will flash and the buzzer will beep. The status LEDs will show the system status. The system performs an automatic retract. No other features are available in this mode.

Low Voltage Signal
If LOW VOLTAGE light is on solid, it is an indication of a charging system problem. Turn ignition OFF and then back ON to reset system. If LOW VOLTAGE light persists, test battery under load at battery and at the motor solenoid on the pump unit. Check all power and ground connections at the battery, alternator and chassis.

Preventative Maintenance Procedures

1. Change fluid in RESERVOIR ONLY when contaminated.
   • Check fluid only when jacks are fully retracted.
   • Always fill the reservoir with the jacks in the fully retracted position. Filling reservoir when jacks are extended will cause reservoir to overflow into its compartment when jacks are retracted.
   • When checking fluid level, fluid should be within ¼” of fill spout lip.
2. Check the fluid level every month.
3. Inspect and clean all Pump Unit electrical connections every 12 months. If corrosion is evident, spray unit with WD-40 or equivalent.
4. Remove dirt and road debris from jacks as needed.
5. 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 your coach is located in a salty environment, it is recommended to spray the rods every 4 to 6 weeks.

Latched Out Warning

Warning
Your coach should be supported at both front and rear axles with jack stands before working underneath. Failure to do so may result in personal injury or death.
LATCHED ERROR mode is “Wait”, “Jacks Down”, “Park Brake”, “Excess Slope” and “Low Voltage” lights flashing.

1. Battery voltage below 10.0V DC.
2. Retract time over 67 seconds in auto retract.
3. This is the only LATCHED ERROR mode.
4. To RESET, push all 4 diamond-shaped jack buttons at the same time (Fig. 8A).
