Automatic reset mode
The alarm signal is output for approximately 400 ms. The
alarm is automatically reset after approximately 400 ms if
the cause of the alarm is cleared within this time. If the cause
of the alarm is not cleared within approximately 400 ms, it
will be reset once the cause of the alarm has been cleared.
This mode is the default setting.

When an alarm signal is output, it is continuously output even
after the cause of the alarm is cleared. The alarm is reset
when the power is turned off and then on again if the cause
of the alarm has been cleared.
