EXTENDING LEGS
• Outrigger legs are extending normally
RETRACTING LEGS
• Outrigger legs are extending normally
OUTRIGGERS LOCKED
• An outrigger function is selected but not allowed (for example, the switch was closed at
power-ON)
INTERLOCKED**
• An interlock shutdown is active, preventing one or more functions. The interlock can be due to
many different causes …
**Press <ENTER> from the MODE display to see the precise cause of the interlock
(listed below) – press <ESC> from that display to return to the MODE display:
TEST MODE
• The system test mode is active – switch power off and on again to clear
TILTED
• The vehicle is tilted beyond limits, descend, then move vehicle to a more level location
OVERLOADED
• The vehicle platform is overloaded, reduce platform load. (CE option only)
TOO HIGH
• The vehicle platform is too high to allow some functions – descend first
ARMGUARD
• During descent, the system is configured to stop movement to provide an armguard delay –
release and re-select DOWN to continue lowering (CE option only)
TOO HOT
• The EZLIFT heatsink has reached 75ºc, preventing all functions except lowering. Functions will
be allowed again when the heatsink cools to below 70ºc.
• The heatsink temperature can be viewed in the DIAGNOSTICS/SYSTEM/ TEMPERATURE dis-
play, ID # 2a5.
• The heatsink must be bolted to a significant metal panel of the vehicle, capable of dissipating
heat to the environment.
UNCALIBRATED
• The height and/or pressure sensors have not been calibrated see CALIBRATION OF OVER-
LOAD SYSTEM (CE option only) .
• If machine is not equipped with Overload system, refer to SETUPS table and change those
personalities that do not match the figure listed in the table.
EXTERNAL ALL, EXTERNAL DRIVE, EXTERNAL LIFT
• An external cutout input is preventing functions – determine the cause of the external cutout
(for example, a limit switch)
