OPERATION AS AUTO HEIGHT CONTROL SYSTEM
The auto height control system is active when both the large red power wire and the accessory
power wire are on. When the accessory power is off the display and height control will shut
down to prevent draining the battery down. One exception is that if the bag dump is active and
the ignition is turned off, the control system will continue to operate until the bag dump is
completed and will then shut down.
The display unit has a 2 line, full character display with three switches on each side. The
display unit communicates to the control system through two wires. The center left switch
selects the different functions and toggles the display screens. The center right switch acts as
the manual up/down selector. The four corner switches operate the four corner bags in manual
or programming modes and also operate as menu selection in other modes. Each of the
operating modes will be discussed in detail.
Manual control:
The tank pressure area will display “AIR” if a tank pressure sender is not connected. Pressing
the up/down select switch will change the operation of the four corner switches. When
“MANUAL UP” is displayed the corner switches will raise their respective bags for as long as the
button is held. When “MANUAL DOWN” is displayed the corner switches will lower the bags.
More than one switch can be held at a time.
