Homing Jacks
1. Introduce an error - disconnect one of the hall effect sensor
wires at the controller.
2. Attempt to operate the jack that is associated with the sensor
wire that was disconnected. The touch pad screen will display
an error for that jack.
3. Reconnect the hall effect sensor wire. Manually extend all jacks
down a minimum of 6 inches.
4. Press and hold the retract button until all of the jacks begin to
retract. The jacks will retract until they reach the hard current
limit.
5. The jacks are now “Homed.”

NOTE: If the jacks do not retract, an error should display on
the touch pad screen. This is typically caused by wiring
interruption.
Zero Point Calibration
The “Zero Point” is the programmed point that the unit will return
to each time the Auto Level feature is used. The “Zero Point”
must be programmed prior to using the Auto Level feature to
ensure the proper operation of the system.
NOTE: Prior to starting this procedure, double check all
connections on the controller, jacks, and touch pad.
1. Manually run the jacks to level the unit. This is best achieved by
placing a level in the center of the unit and leveling it both front
to back and then side to side. (See “Basic Jack Operation” for
instructions on how to manually operate the system).
2. Once the unit is level, turn off the touch pad.
3. With the touch pad off, press and release the “FRONT” button
(Fig. 17A) fi ve (5) times and then press and release the
“REAR” button (Fig. 17B) fi ve (5) times.
4. The touch pad will fl ash and beep and the display will read
“ZERO POINT CALIBRATION ENTER to set, Power to Exit”
(Fig. 17C).
5. To set the current position as the zero point, press the
“ENTER” button (Fig. 17D).
Basic Jack Operation
Landing gear jacks can be operated any time the system is “ON”.
By pushing the “FRONT” button (Fig. 16G), both front or landing
gear jacks can be extended. By pushing either the “LEFT” (Fig.
16H) or “RIGHT” (Fig. 16I) buttons, the individual front jacks can
be extended. If the touch pad is put in the retract mode, indicated
by the orange illuminated LED next to the “RETRACT” button
(Fig. 16D), the front jacks can be retracted together by pushing
the “FRONT” button (Fig. 16G) or individually by pressing “LEFT”
(Fig. 16H) or “RIGHT” (Fig. 16I) buttons, while simultaneously
pressing the “FRONT” button (Fig. 16G).
The rear jacks can only be extended when the touch pad is in
the manual mode. Once system is in manual mode, pressing
the “REAR” button (Fig. 16J) will extend both rear jacks at the
same time. To extend individual rear jacks, press the “LEFT”
(Fig. 16H) or “RIGHT” (Fig. 16I) buttons while simultaneously
pressing the “REAR” button (Fig. 16J) depending on which jack
needs to be operated. If the touch pad is put in the retract mode,
indicated by the orange illuminated LED next to the “RETRACT”
button (Fig. 16D), the rear jacks can be retracted together by
pushing the “REAR” button (Fig. 16J) or individually by pressing
either the “LEFT” (Fig. 16H) or “RIGHT” (Fig. 16I) buttons, while
simultaneously pressing the “REAR” button (Fig. 16J).
NOTE: If the rear jacks will not operate individually using the method
described above, but they operate properly when Auto Level is
performed, the Twist Prevention Protection system has locked out
the operation to prevent damage to the frame of the unit.
