Secton 16 - Control System
Two calibrations must be performed for all versions of this machine. A third calibration must be
performed on machines equipped with Overlord Sensing System:
Level Sensor Calibration
Height Sensor Calibration
Machines equipped with the optional Overload Sensing System package must perform the
following calibration:
Load Calibration
Pre-Calibration Setup
Park the machine on an absolute flat and level surface free from overhead obstructions that will
prevent full boom elevation. Lower the boom completely into its cradle. Use a inclinometer or spirit
level to check the platform state at level and level platform if out of level.
Level Sensors calibration must be performed first. When calibrating the level sensors, be aware that
the following sensors are all calibrated simultaneously:
GP400 Control Module’s Integral Level Sensor that measures chassis angles
Two dual-axis CAN-Tilt Angle Transducers that measure platform angle; both mounted at the
front of the Platform Level Bell Crank.
Therefore, before calibration can begin:
Use a framers/spirit level to check that the chassis is level both fore-and-aft and side-to-side.
The PLATFORM must be leveled both fore-and-aft and side-to-side through the use of a
framers/spirit level placed on the top or bottom side of the platform toe boards. Use the Platform
Level toggle function to level the platform fore-and-aft.
After the platform has been confirmed to be absolutely level, proceed to the Level Sensors Calibration
instructions.
The sensors used on the this machine are very sensitive and can detect even the slightest movement
of the parts that they monitor. Therefore it is it is absolutely mandatory that the previous steps be
performed with utmost care and precision before calibration.
Level Sensors Calibration
Park machine on flat level surface and ensure that the chassis, the steering axle and the
platform are level, as described in Pre-Calibration Setup. Turn the engine off using the Start/Stop
toggle switch.
Open the control module door, then open the lower control box door to access the GP400.
Connect the EZ-Cal.
Power up the control system by turning the Key Switch on the lower controls to Base. The EZ-
Cal display will read HELP PRESS ENTER.
Press the right arrow twice until the display reads, “ACCESS LEVEL 3”. Press ENTER
Using the up arrow and right arrow, enter the numbers 1775, then press ENTER. The display
should now read “ACCESS LEVEL 2”
Press the right arrow twice until the display reads “SETUPS”. Press ENTER.
Press the right arrow once until the display reads “TILT SETUPS”. Press ENTER.
The display will read “CALIBRATE LEVEL YES: ENTER NO: ESC”
Press ENTER, then press ENTER again. The State-of-Level indicator should now read 0.0 - 0.0
or within .1 degrees.
Level calibration is complete. Proceed to Height Calibration.
