“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.
