Level-Up® Motorhome Leveling Troubleshooting Guide
Safety Features
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 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,
"Emergency Retract" appears in the readout window and the alarm beeper will activate. The system will
then automatically retract the jacks until the jacks are fully retracted or a button is pressed on the touchpad
to abort the auto retract.
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, see "Emergency Retract" alarm below for pressure loss conditions.
“Emergency Retract" Alarm
The Dual Sensor Leveling System is designed to sound an alarm and display "EMERGENCY RETRACT" on the
LCD display in the event of a significant pressure loss indicated by the pressure switch (Fig. 4). The pressure
switch is a pressure indicator. Once the pump reaches 2150 psi, the pressure switch opens, disconnecting
the circuit indicating the jacks have been retracted. The following items can indicate pressure loss triggering
the emergency retract function:
1. Hose leak - external fluid leak through the hose or at the fittings. Inspect the hose and fittings for a
failed crimp or swage. Tighten any loose fittings. Replace any damaged hose.
2. Leveling jack external leak - fluid is leaking outside of the jack cylinder. Jack must be replaced.
3. Leveling jack internal bypass - a seal has failed within the jack. Jack must be replaced.
4. Power unit manifold leak - check all hose fittings and valves for leaks; tighten all loose connections.
Manifold may bypass internally due to a machining issue or cracked block. Replace power unit.
5. Internal power unit failure - the pump or direction valve has failed and can no longer hold pressure.
Replace power unit.
NOTE: All of the above will cause an open pressure switch to close due to loss of pressure. In turn, the
controller will engage the emergency retract when the pressure switch is closed, the ignition is in
the run position and the parking brake is disengaged.
