625S TROUBLE SHOOTING GUIDE
On the right hand side of the touch panel there are four (4) red and four (4) yellow indicator lights. The four red indicator lights
are JACK DOWN warning lights. There is one light for each jack. These warning lights come on when their respective jacks
are extended about 1/4 to 1/2 inch. The four yellow indicator lights are level indicators, front, left side, right side and rear. A lit
yellow level light indicates that a side, end or corner is low. When all four yellow level lights are out, the vehicle is level within
the tolerance of the level sensing unit.
Use the UP ARROW (Extend jack pairs) and DOWN ARROW (Retract jack pairs) buttons to extend jack pairs as
needed to level and stabilize the vehicle. Side level lights should be turned off before turning off front or rear level lights.
STORE MODE
The touch panel has a "STORE" button and light. The ignition must be in the "ON" or "ACC." position. The STORE light will
come on when the "STORE" button is pushed. The STORE light will go out six (6) minutes after the last of the four individual
red WARNING lights go out. If the vehicle is equipped with an air suspension, the leveling system will return to the travel mode
The "STORE" button should always be used to retract the jacks. This allows the system to store any jack that extends due to

thermal expansion of the hydraulic fluid while traveling. When traveling, if a jack extends enough to allow a jack warning switch
to turn on, the processor will turn the appropriate solenoid valve on so the jack can retract. The master warning light and buzzer
will NOT come on at this time. If thirty (30) seconds after the solenoid valve is turned on the warning switch is still on, the
processor will turn the master warning light, the buzzer and the appropriate red WARNING light on the touch panel on.
IMPORTANT: When testing a leveling system, all four sets of UP and DOWN arrow buttons should be used to make
sure the complete system operates correctly, including the red WARNING lights and the yellow LEVEL lights. If the
system will not work in the manual mode it is very unlikely the system will function properly in the automatic mode.

will start the automatic store procedure. Pushing the rocker switch either direction will halt the automatic store
procedure.
WARNING:
IF THE VEHICLE IS EQUIPPED WITH A PILOT AIR DUMP SYSTEM, THE SUSPENSION WILL DUMP
AIR AND START TO DROP AS SOON AS AN AUTOMATIC LEVEL BUTTON OR ROCKER SWITCH IS PUSHED.
ALTHOUGH THE AUTOMATIC LEVELING PROCEDURE WILL HALT WHEN AN "EMERGENCY STOP", "STORE",
"AUTO LEVEL" OR ROCKER SWITCH IS PUSHED, THE VEHICLE SUSPENSION WILL CONTINUE TO DROP.

The pump will go to relief and trip a 3000# pressure switch on the leveling manifold. The "EXCESS SLOPE" light will come on.
Jacks that have not been extended will not extend when the "EXCESS SLOPE" light is on. The "EXCESS SLOPE" light will be
on whenever the ignition is on until the park brake is released (with the ignition on) or the jacks are completely retracted with the
