DIAGNOSTICS

The EZcal display has a number of diagnostic tools to aid troubleshooting. To access these with the
machine switched on, press and hold "ESC" for 5 seconds until "#### MENU: HELP: PRESS EN-
TER" is displayed. Press "ENTER" for a top level fault message.
For more detailed diagnostics from the top menu, scroll right to "DIAGNOSTICS" and press

SYSTEM

The information listed below is relevant to this machine (ignore any other data).
MODE: Ground or platform mode selected.
•
SUPPLY: The supply voltage at the GP400.
•
VALVE SUPPLY: Valve supply "ON" or "OFF".
•
TILT: This is the platform tilt angle in X and Y.
•
From tilt, press "ENTER" for chassis tilt angle in X and Y.
AXLE: Press "ENTER" for "AXLE Tilt angle".
•
TILTED: "YES" if the platform angle exceeds 2 degrees in X or Y.
•
HEIGHT: The platform height as a percentage of full elevation.
•
LOAD: The platform load as a percentage of full Safe Working Load (SWL).
•
OVERLOADED: "YES" if the platform load exceeds 120% of the Safe Working Load (SWL).
•
LAST MOVED: The last movement.
•
ELEVATED: "YES" if the height is above the elevation height.
•

PLATFORM

The information listed below is relevant to this machine (ignore any other data).
• TRIGGER: "ON" if the joystick trigger is activated.
