Chapter 6 - GP RUN and Errors
GP-477R/577R Series User's Manual
6-16
• When the displayed error number is 8*, or 5*, use only the left column as
the error number.
• In Toshiba's PROSEC T Series, the Error Code is 4 places long; on the GP,
Error Numbers are displayed and changed into Hexadecimal.
E.g.
• With the Allen-Bradley PLC-5 and SLC-500 Series, the EXT/STS error
codes have been re-mapped to start at D0 HEX, so they will not conflict
with other error codes. When looking up the error number in the PLC
manual, subtract D0 h from the GP error code to find its error value.
E.g. GP Error Code PLC Error Code
D1 —> 01
EA —> 1A
SCREEN MEMORY DATA IS CORRUPT
Displays when the checksum of the screen memory data does not match
because of a corruption in the screen files.
This error message is followed by error codes. By referring to the error
code, you can check the screens that have errors. When a screen file has
been corrupted, delete that file, and make a new one (or recall a backup
copy if available).

(Displays only one per Screen Number.)
CLOCK SET UP ERROR
This message displays when the lithium backup battery’s voltage for
the internal clock runs low and may be due to the GP’s being unused
for a period of time. To clear the error, you will need to turn the GP’s
power OFF and then ON. Leave the GP ON continuously and the
battery’s charge will become sufficent for backup after 24 hours, and
will be fully charged in approximately 96 hours. If the battery is
incorrectly replaced, the battery may explode. To avoid the danger,
please do not replace the battery yourself. When the battery needs a
replacement, please consult with your local GP distributor.
After changing the backup battery, set up the internal clock.
