Low Voltage Signal
1.
The vehicle requires 12.7V DC to operate in the AUTO mode.
A.
If the voltage is too low, the touchpad's LCD screen (Fig. 1E) will display "LOW VOLTAGE."
B.
If voltage drops below 12.7V DC, the leveling system will only operate in manual mode and
continue to display "LOW VOLTAGE."
2.
If voltage drops below 9.5V DC during automatic or manual operation "LOW VOLTAGE" will appear in
the LCD screen and the leveling system will stop operating.
Automatic Safety Shutoff
The touchpad will automatically turn off after four minutes of inactivity. To reset the leveling system, the
coach ignition must be turned off, then back on and the ON/OFF (power) button (Fig. 1K) must be pressed.
Drive Away Protection System
If the coach's 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.
“Jacks Down" Alarm
The leveling system is designed to sound an alarm and illuminate the touchpad in the event of two possible
scenarios:
1.
A retract hose leak.
2.
The pressure holding the jacks in the retracted position falls to approximately 1500 psi, which activates
the alarm. If the alarm sounds and the touchpad illuminates and flashes while driving the vehicle:
A.
Immediately find an area to safely pull the vehicle off of the roadway.
B.
Set the PARKING BRAKE.
C.
Inspect all jacks, hoses and valves for leaks.
D.
If no leaks are observed:
I.
Turn leveling system touchpad on.
II.
Press RETRACT button (Fig. 1D).
III.
Wait until “JACKS DOWN” light and alarm turn off.
IV.
Inspect jacks. If jacks are retracted and no leaks are observed, vehicle can be driven.
E.
If system is leaking or alarm does not subside after applying step 2, disconnect wires from pressure
switch and proceed immediately to a service center.
NOTE:
The pressure switch is a blue and gold colored valve located on the power unit manifold identified
by the spark proof style connector with yellow and black wires. See figure 5.
NOTE:
For prolonged travel to the service center, periodically stop and check the disposition of the leveling
jacks to make sure they are not extending.
For Diesel Units with Air Bag Suspensions ONLY:
The leveling control will automatically detect an air bag system. If the unit does not use air bags, the
touchpad LCD screen will display “NO” for air bag control. If the LCD screen reads "NO," but an air bag
system is present on the unit:
1.
Confirm harness is connected properly.
2.
Run the auto level function.
3.
Recalibrate the Zero Point.
4.
If the air bag system is still not being detected, contact the OEM for more information.
