TROUBLESHOOTING APPENDICES INDEX
When multiple enunciators(F) detected are canceled, the first one with No. F only is
canceled.
If the canceling of errors is performed when multiple continuation errors are occurring,
the LED indication and error information of the CPU module operate as follows.
Refer to the following manual for details of error canceling.
QSCPU User's Manual (Function Explanation, Program Fundamentals)
POINT
1. When the error is canceled with the error code to be canceled stored in the
SD50, the lower one digit of the code is neglected.
(Example)
If error codes 2100 and 2106 occur, and error code 2100 to cancel error
code 2106.
If error codes 2100 and 2125 occur, error code 2125 is not canceled even if
error code 2100 is canceled.
2. Errors developed due to trouble in other than the CPU module are not
canceled even if the special relay (SM50) and special register (SD50) are
used to cancel the error.
(Example)
Since "INTELLIGENT FUNCTION MODULE DOWN" is the error that
occurred in the base unit, intelligent function module, etc. the error cause
cannot be removed even if the error is canceled by the special relay (SM50)
and special register (SD50).
Refer to the error code list and remove the error cause.
Error Canceling Status
LED Indication *1
("ERR." LED, "BAT." LED,
"USER" LED)
Error Information
(SM0, SM1, SM5, SM16, SD0
to 26)
Before canceling errors On
The error information of the
continuation error that
occurred last is stored.
The error which occurred last
is cancelled.
(The continuation error that is
not canceled remains.)
On
Returned to the status without
error.
Errors other than the
continuation error that
occurred last are cancelled.
(The continuation error that is
not canceled remains.)
On
No change
(The error information that
occurred last is retained.)
All the continuation errors are
cancelled.
Off No error
*1: 1) Error code: When 1600 (BATTERY ERROR) occurs, only "BAT." LED turns on.
Error code: When canceling the error code 1600, "BAT." LED turns off.
2) Error code: When 9000 (F****) occurs, only "USER" LED turns on.
Error code: When canceling the error code 9000, "USER" LED turns off.
