Error Messages
There are basically three types of errors for which messages are displayed:
initialization errors, non-fatal operating errors, and fatal operating errors.
Most of these are also indicated by FAL number being transferred to the FAL
area of the SR area.
The type of error can be quickly determined from the indicators on the CPU,
as described below for the three types of errors. If the status of an indicator is
not mentioned in the description, it makes no difference whether it is lit or not.
After eliminating the cause of an error, clear the error message from memory
before resuming operation.
Asterisks in the error messages in the following tables indicate variable nu-
meric data. An actual number would appear on the display.
The following error messages appear before program execution has been
started. The POWER indicator will be lit and the RUN indicator will not be lit
for either of these. The RUN output will be OFF for each of these errors.
