3.
What Is a Standby
Sequence For?
Particularly with a
lower-limit alarm, the
temperature is often below
the alarm point when
temperature control is
started. In this case, an
alarm would be output at
the start of operation. To
prevent this, a standby
sequence is used to disable
the first alarm.
In the default settings, the standby sequence is restarted (and
the alarm is turned OFF) when operation is started, when the
SP is changed, or when the alarm temperature is changed.
You can change the conditions for restarting the standby
sequence.
