If a Power Failure Occurs during Operation
Momentary Power Failures shorter than 20 ms
The controller is not affected at all and continues normal operation.
Power Failures of 20 ms or longer
The alarm function of the controller continues to work normally. (Alarms with the
stand-by feature temporarily return to their stand-by state, however.)
Setting parameters that have already been configured retain their settings.
Auto-tuning is cancelled.
After recovery from a power failure, control action resumes in the same mode as the
one before the occurrence of the power failure. The control output begins with the
preset output value.
