ESSAGES
NOTE:
It is important to understand that an error message will only be available if the red Diagnostic
LED is flashing. If the machine is not operating properly and the red Diagnostic LED is not
flashing, the trouble may lie with something not monitored by the electronic control system, i.e. a
switch, hydraulic valve or wiring damage.
There are two different menus that you can access for message retrieval; MODE and
HELP.
M O D E M
E N U
Allows the technician to see the current state of the controller with a short description.
Go to, DIAGNOSTICS/SYSTEM/MODE (EZ-Cal Flow Chart 2, ID# 2a1). Pressing
ENTER a second time will provide additional information with certain messages.
H E L P M
E N U
Provides various HELP messages to identify failure modes.
Some error messages may also be identified by counting the number of times the red
LED flashes on the controller so that even without access to an EZ-Cal, some simple
diagnostics are possible. However, it is recommended to use an EZ-Cal to diagnose
problems, and not rely on the LED! The EZ-Cal provides a much higher detail of
information.
MODE M
ESSAGE
• Connect the EZ-Cal (see illustration).
The display will read, “HELP: PRESS ENTER”.
• Press Enter to display the current message.
• Refer to the following list of HELP messages to better understand the nature of the message
or fault.
• If the GP400 does not register a fault, the display will read EVERYTHING OK.
S
CROLLING
M
ESSAGE
Pressing ENTER twice will provide a scrolling message of the current message (if one
exists) followed by a log of previous operations and/or errors that occurred immediately
prior, starting with most recent. All messages are cleared whenever the system is
powered down.
Other helpful menus available include DIAGNOSTICS which allows the technician to
monitor specific plug input/output information. Refer to EZ-Cal Flow Chart 2 –
Diagnostics (ANSI Page 4b-11 – CE Page 4b-13).

The purpose of MODE is to indicate, in real time, the current state of the controller with a
short description.
INITIALIZING
• The system is preparing to operate, immediately after power-on.
SHUTDOWN!
• The system cannot operate – for example both the PLATFORM & GROUND inputs are active
together.
CHECK CANBUS
• The system cannot operate – CANBUS communications is not successful (for example wire
damage to the platform)
