SECTION 6 - JLG CONTROL SYSTEM
Initial display when system test is run while running certain "critical" checks are made.
The analyzer must be connected to the active control station to run the system test
The system test cannot run unless the CAN Bus is operating properly
The system test cannot run with MTM-reported battery voltage below 39.5V (not UGM-compen-
sated value)
The system test cannot run with the MTM-reported battery voltage above 65V
Reported vehicle speed must = 0 Hz (or mph)
The vehicle is tilted > 3° or the tilt sensor if faulty
In platform mode, the footswitch must be open at the start of the test.
In platform mode, the operator must close the footswitch when this message is displayed
The two footswitch signals are not changing together, probably because one is open circuit. Check
footswitch and wiring.
In platform mode, the operator must open the footswitch when this message is displayed.
Load Sensing is configured and the ground module considers the platform to be overloaded
*Check for Footswitch closed
*Wait for Footswitch to open
*The operator must engage and hold the footswitch for the next batch of tests to be successful.
This is due to the hardware high side driver cutout in the ground module
