Prior to Operation
The leveling system shall 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. All jack landing locations are cleared of debris and obstructions. 4. The coach transmission should be in the neutral or 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
Selection 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.
· After 4 minutes of no operation. Leveling cycle cannot be started until all jacks are fully retracted. · 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.
NOTE: When in alarm mode, the only available feature is to retract all jacks. · The Wait LED shows the status of Air/Auxiliary features. · 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.

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 trailer 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 (controller module must be fully secured in production intent location), first run a manual leveling sequence using carpenters level, get the vehicle to the desired level point. Then activate the Level Zero point configuration mode.
Check the part number printed on the faceplate sticker of your controller. If the controller part number is 2020003067 or newer, follow the procedure in “Setting the Zero Point for Newer Controller Models.” If the controller part number is 365150, 364557, 175226, or any other number, follow the procedure in “Setting the Zero Point for Obsolete Controller Models.”

“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. A “RETRACT” hose leaks.
B. 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. A. Check fluid only when jacks are fully retracted. B. 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.
C. When checking fluid level, fluid should be within 1/4″ 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
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. All revisions prior to “G” controllers treat this error as regular ERROR mode. To RESET, push all 4 diamond-shaped jack buttons at the same time (Fig. 16A).
