Shutdown Help Messages

This section lists “shutdown” HELP messages – functions can be shut down to prevent them being

used:

SHUTDOWN - CHECK EMS SWITCHES! ____________________ Flash Code: 2/1

The Base/Platform selector switch position indicates the mode in which the system must operate

if both are active together; the system does not know how to function

FUNCTIONS LOCKED - TEST MODE SELECTED _____________ Flash Code: 2/2

Test mode is not accessible with this system. Switch power off/on to reset to normal operation

FUNCTIONS LOCKED - ARMGUARD (CE option only)_________ Flash Code: 2/2

During descent, the System can stop movement for a configurable time, to allow a safety check

that no-one is close to the machine. The operator must release and re-select DOWN to continue

lowering (after the delay time-out).

FUNCTIONS LOCKED – OVERLOADED (CE option only) ______ Flash Code: 2/2

System overload features are active, and the platform is excessively loaded to allow operation

– the platform load must be reduced.

FUNCTIONS LOCKED – UNDERLOADED (CE option only) _____ Flash Code: 2/2

System overload features are active, and the platform load is too low to be valid – this could

be caused by erroneous calibration, a sensor fault, or a change in the vehicle mechanics/

hydraulics.

FUNCTIONS LOCKED - TOO HIGH _________________________ Flash Code: 2/2

The platform is raised too high to allow some functions. Certain functions may not be allowed

above certain elevations.

Check operator’s manual or ADJUSTMENTS/HEIGHTS/MAX DRIVE and MAX LIFT to see if

drive and/or lift is allowed at all heights.

FUNCTIONS LOCKED - TILTED ___________________________ Flash Code: 2/2

The vehicle is tilted too much to allow some functions.

Check operator’s manual or ADJUSTMENTS/TILT/Xtrip and Ytrip, which determine the

maximum allowed vehicle tilt.

Refer to EZ-Cal Flow Chart 1 – Adjustments and Setup.

FUNCTIONS LOCKED - EXTERNAL SHUTDOWN _____________ Flash Code: 2/2

An external shutdown is preventing functions – check DIAGNOSTICS/SYSTEM/ MODE/

INTERLOCK to see which external interlock is active.

same time.
