5.16.3 Setting of temperature alarm monitoring method and alarm
generation timing
Examples of temperature alarm monitoring method setting and alarm
generation timing are shown below.
When "Automatic monitoring" is selected
[1] Circulating fluid temperature when starting operation: Approximately 20
o
C
[2] Circulating fluid set temperature: 15
o
C
[3] "AS.21: Temperature alarm monitoring method": Select "Automatic monitoring".
("----" (invalid setting) will be shown for "AS.22: Monitoring start timer".)
[4] "AS.04: Detection temp. for the circulating fluid discharge temp. increase": Set to "16
o
C".
[5] "AS.06: Detection temp. for the circulating fluid discharge temp. drop": Set to "14
o
C".
[6] "AS.23: Range over detection timer "Set to "600 sec".
Fig 5.16-1 Alarm generation timing
-Alarm generation timing
Status (1): Temperature alarm monitoring starts by starting the chiller operation. As the
circulating fluid temperature at this time is 20
o
C, "AS.06" starts alarm monitoring
at the same time as the operation start.
Status (2): The circulating fluid temperature becomes within the set range of "AS.04", and
starts "AS.04" alarm monitoring".
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): Alarm "AL03: Circulating fluid discharge temp. increase" will be generated after
600 seconds that is set for the "AS.23: Range over detection timer" after the
circulating fluid temperature exceeds the threshold of "AS.04".
