Fig 5.16-2 Alarm generation timing
 -Alarm generation timing
Status (1): Start operation of the chiller. As the circulating fluid temperature is within the set
range of "AS.06", "AS.06" alarm monitoring starts.
Status (2): The circulating fluid temperature becomes within the set range of "AS.04".
"AS.04" alarm monitoring starts.
Status (3): The circulating fluid temperature exceeds the threshold of "AS.06", but the alarm
will not be generated as it has returned within the 600 sec range of the "AS.23:
Range over detecting timer".
Status (4): The circulating fluid temperature exceeds the threshold of "AS.04", but the alarm
will not be generated as it has returned within the 600 sec range of the "AS.23:
Range over detecting timer".
Status (5): 50 minutes passes after starting operation. Alarm monitoring has started. It
shows that the "50 min" setting does not influence the alarm monitoring under
these conditions.
Status (6): Alarm will be generated after 600 seconds that is set for "AS.23: Range over
detection timer" after the circulating fluid temperature exceeds the threshold of
"AS.04".
