825 LSS HAS NOT BEEN CALI-
BRATED The Load Sensing System has never
been calibrated and the control system
assumes that the platform is over-
loaded. • Empty Platform and Calibrate the Load Sensing System using
the calibration procedure in the LSS Manual.
• HEALTH (Status LED) - ON
8-4 Elevation Switch
DTC FAULT MESSAGE DESCRIPTION CHECK
84109 ELEVATION SWITCH CON-
TACTS DISAGREEMENT The Elevation Switch contacts are the
same (high or low). Since the contacts
should always be complimentary, the
system assumes the platform is Ele-
vated. • Check the wiring and the switch or replace the switch to clear the
fault.
• Health (Status LED) - ON
