GP400 HELP MESSAGES
(
continued)
FUNCTIONS LOCKED - OVERLOADED
2/2
The platform is loaded too high to allow operation – the platform load must be
reduced.
If the overload features are not wanted, be sure to set ADJUSTMENTS/
OVERLOAD TRIP@, LAMP@ or ALARM@ to 0%
FUNCTIONS LOCKED - TEST MODE SELECTED
2/2
When
GP400
test mode has been activated (see DIAGNOSTICS/OUTPUTS), no
functions are allowed. Switch power off/on to reset to normal operation
FUNCTIONS LOCKED - TILTED
2/2
The machine is tilted too much to allow some functions.
(see SETUPS/TILT SETUPS/TILT SHUTDOWN and ELEV.TILT SHUTDOWN)
FUNCTIONS LOCKED - TOO HIGH
2/2
The platform is raised too high to allow some functions.
(see ADJUSTMENTS/HEIGHTS/MAX DRIVE and MAX LIFT)
FUNCTIONS LOCKED - UNDERLOADED
2/2
Platform 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 machine mechanics/hydraulics
(see SETUPS/LOAD SETUPS/ FAULTY LOAD)
HEIGHT NOT CALIBRATED
1/1
Height based functions are required (for example MAX DRIVE is configured), but
height has not been calibrated
Calibrate height (see SETUPS/HEIGHT SETUPS) or ensure that all height
settings are either 0% or 101%
NOT CALIBRATED
1/1
Height and load based functions are required (for example platform overload is
configured), but height and/or load has not been calibrated
Calibrate load which includes height calibration
RELEASE GROUND SWITCHES!
2/2
Ground function switches were closed at power-on (or a wiring error is causing
an input to be active always)
RELEASE JOYSTICK!
2/2
Platform joystick was selected at power-on (or a wiring error is causing an input
to be active always)
Platform joystick selected for too long without trigger switch (see
SETUPS/INTERLOCKS/ TRIGGERwait)
