WDT Errors
A WDT timer occurs when a system runaway causes the watchdog timer to time out.
If a WDT error is detected when the system runs out of control during operation, the RUN indicator will
go out and the NORM/ERR indicators will light red. There is no error code for a WDT error and no
record is recorded in the system error log.
