setting.
An error has occurred
during check of the PC or
EM Unit memory, or
program transfer could
not be completed at
start-up.
Probable Cause
The following errors occur after program execution has been started. PC opera-
tion and program execution will stop and all outputs from the PC will be turned
OFF when any of the following errors occur.
None of the CPU Unit indicators will be lit for the power interruption error, and
only the POWER indicator will be lit for the Expansion Rack power interruption
error. The POWER and WDT indicators will be lit for the CPU Unit error. For all
other fatal operating errors, the POWER and ERROR indicators will be lit. The
RUN output will be OFF.
1. Error codes 0200 to 0215 indicate CPU Bus Units #00 to #15, respectively,

Check power supply voltage and
power lines. Try to power-up again.
Turn on the power supply to the
Expansion CPU and Expansion I/O
Racks.
Turn the power OFF and restart.
Check Memory Card and EM Unit
to make sure they are mounted and
backed up properly. Perform a
Program Check Operation to locate
cause of error. If error not
correctable, try inputting program
again.
Check battery and replace if
necessary.
Check the errant Unit.
Check the power supply
voltage and lines.
