6) Turn special relay SM50 OFF.
(a) Error canceling procedure for multiple errors
Because the description of the error information special relays/registers (SM0,
SM1, SM5, SM16, SD0 to 26) are cleared when the last error to occur (the error
stored in special register SD0) is canceled, the information on errors that have not
been canceled cannot be obtained from the special relays/registers.
Cancel errors that have not been canceled by obtaining errors that have occurred
in the past from the error history (
Section 6.8).
(2) State after error canceled
If the CPU module is recovered by canceling the error, the special relays, special
registers, and LEDs related to errors return to the pre-error states.
The error history does not change.
If the same error occurs again after it has been canceled, it is recorded into the error
history again.
(3) Canceling annunciator
When canceling multiple detected annunciators, only the F number first detected is
canceled.
(4) Canceling errors when multiple erros occur
When multiple continuation errors occur and an error is canceled, the CPU module
LED display and error information are as follows.
* 1: (1) When error code: 1600("BATTERY ERROR") occurs, only the "BAT." LED lights up.
When error code: 1600 is canceled, the "BAT." LED goes out.
(2) When error code: 9000(F****) occurs, only the "USER" LED lights up.
When error code: 9000 is canceled, the "USER" LED goes out.

Error information
(SM0, SM15, SM16, SD0 - 26)
Before error canceled ON The error information for the continuation
error that occurred last is stored.
The continuation error that occurred
last is canceled.
(There are continuation errors
remaining that have not been
canceled.) ON Returns to the no-error state.
A continuation error other than the
last one is canceled.
(There are continuation errors
remaining that have not been
canceled.) ON No change
(The error information for the continuation
error that occurred last is retained.)
All the continuation errors are
canceled. OFF No error
