Setting The Null; Helpful Hints - Equalizer Systems Auto-Level Troubleshooting & Warranty Manual

Auto-Level Operation
Power on:
Push and release the Power keypad button to engage power. All lights should come on then most
will go out. The LED light next to the Power button should be lit RED when power is on. Other lights should go
out, if they do not refer to the keypad LED section. If the jacks down lights are on they must be cleared by
pressing the all retract button prior to performing Auto-Level.
Front Jacks:
It is required that tow vehicle be disconnected from the trailer prior to leveling with Auto-Level.
Use the down arrow(s) on the control panel (or use the dual leg switch) to extend the front jacks to support the
trailer and lift the trailer from the tow vehicle. After the tow vehicle is removed, lower the front of the trailer so
that the trailer is level front to rear (visually level). Generally, it will work best if the front is slightly lower that
the rear. This is somewhat a trial and error/learning as all trailer units seem be slightly different.
Auto-Level:
Press the Auto-Level button and release. The system will send out a continuous series of beeps and
the "Operating" LED will flash RED to let you know Auto-Level is operation the rear legs will be deployed and
then the system will use the front and the rear legs to automatically level the coach. When completed, the keypad
will signal the successful completion with a dual-stage tone. The keypad may be left on once level has been
achieved. The keypad will enter "sleep mode" after five minutes of inactivity. If the unit is not level after the
process is complete see the section on setting the Null.
Retracting the Jacks:
The Equalizer System does provide the ability to retract the jacks using the UP buttons for jacks. However, these
buttons are not intended to be used for retracting the jacks to their stowed position prior to travel. The Up arrows
are to be used only for retracting the jacks to help level the coach. The All Retract button must be pressed to
insure the system is ready/safe for travel. All jacks (rear only) will automatically retract and return to stowed
position when the ALL RETRACT button is pressed and released. The front jacks will need to be retracted using
the UP arrow(s) to the stowed position after coupling to the tow vehicle. When All retract is pressed the pump
will run in retract for approximately 5 seconds after the last (rear jack) jack has been fully retracted- or until a
time limit of 90 seconds has been reached.
*It is always the responsibility of the coach operator to visually confirm that the
Setting the Null: Null is the term used to indicate the levelness of the coach
If the coach is not level following an attempt to Auto-Level, you will need to level the coach and reset the null. To
set the null, push and release the Power button on the Keypad to engage power. The LED light next to the Power
button should be lit RED when the power is on. Level the coach by deploying jacks manually, or by simply
parking the coach on a level site. You do not need to have the jacks deployed to set the null. Use a bubble level on
a flat surface in the center of the coach as a reference. Once the coach is level, turn the power off at the panel.
Depress and hold the Auto-Level button and press and release the Power button and listen for a series of beep.
After the Keypad has beeped 5 to 6 times, release the Auto-Level button (the Keypad will continue to beep as
long as the Auto-Level button is held). You should receive 2 beeps indicating that the new Null has been set the
panel will maintain this setting. Press and release the All Retract button to retract the jacks to the stowed position.

Do not allow excessive motion in the unit during the Auto-Level operation (don't move around in the unit).
This could cause the system to level improperly.

The Auto-Level is a microprocessor controlled system. Proper and adequate battery voltage and permanent
chassis ground are essential.

Your system may be equipped with a manual override option. Refer to the procedure for proper operation of
this option. It is usually better to review this procedure prior to its actual use, rather than having to learn a
new procedure in difficult environments.

If the system has not been used (with the jacks stowed) for over 24 hours, it is recommended that you engage
the All Retract button prior to travel in order to re-pressurize the system.

A lubricant, like WD40, may be used to clean and lubricate the cylinder shafts.
Use the ALL RETRACT button to retract the jacks prior to travel
jacks are fully retracted and safe for travel*
