EZ-Cal Retrieve Mode And Help Messages
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.
MODE Menu
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.
HELP Menu
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 Message
Connect the EZ-Cal (see illustration).
The display will read, “HELP: PRESS ENTER”.
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.
Scrolling Message
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 94 – CE Page
96).
MODE Messages
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.
