n n n n n When OFFLINE mode displays during RUN mode
When the GP changes to OFFLINE mode without the user first pressing the
screen, there is a possibility that the screen data has been damaged. In this case,
after the SYSTEM ERROR displays, the screen automatically reverts to OFFLINE
mode after about 10 seconds. Run the INITIALIZE MEMORY command and
transfer the GP screen data again from your PC.
In most cases, system errors are related to the problems mentioned below.
Environment Related Problems
If an error occurs which has no apparent connection to the GP's current operation,
the error may be due to the condition of GP's operating environment. This can
include noise or electrostatic interference in the power code or the communication
line. In this case you need to check if the power code and the communication line
wiring and FG grounding are correct.
Screen Data or Project Data Related Problems
If an error seems to be caused by a particular GP operation, the error may be
related to the screen or project data transferred to the GP. In this case, try sending
screen data via the FORCE SYSTEM SETUP feature, which will transfer both the
screen data and the project data to the GP.

GP Unit Related Problems
If disconnecting and then re-connecting the power code corrects an error, the
problem may not be related to the GP unit itself. However, to identify if the GP
unit has any problems, run the OFFLINE mode's SELF-DIAGNOSIS program.
Peripheral Equipment Related Problems
(When the GP is equipped with a printer I/F)
If an error occurs only during printout, there may be a problem with the printer.
Check the printer cable wiring and the FG line as well as the printer itself.
When a communication error occurs continuously
(When using the Direct Access method)
If a communication error occurs continuously, the GP may define the error as a
system error. In this case you need to solve the problem causing the original
communication error.
