State ⑨: Manual reset of alarm, "AL.14", "AL.15" cancellation as monitoring condition is not
included.
【Temperature range monitoring function setting example 2】
[1] Circulating fluid temperature at start of operation: about 25℃
[2] Circulating fluid set temperature：15℃
[3] Temperature range monitoring function (upper limit)」： set to「20.0℃」
[4]「Temperature range monitoring function (lower limit）」：set to「10.0℃」
[5]「Monitoring of temperature range monitoring function」： Set to「PW.on」
[6] "Temperature range monitoring start time": set to "30 sec". (It is invalid in continuous
monitoring.)
[7] "Time outside the temperature range monitoring range: set to" 45 sec ".
[8] "TEMP READY alarm output": set to "OFF".
[9] "Temperature range upper limit alarm switching": Set to "WRN".
[10] "Add output of temperature range upper limit alarm": Set to "ON".
[11] "Temperature range lower limit alarm switching": set to "WRN".
[12] "Add output of temperature range lower limit alarm": Set to "ON".
State ①: An alarm "AL.14" is issued when the chiller is activated. "TEMP OUT" output ON.
State ②: Enter temperature monitoring upper and lower limit range, "TEMP OUT" output OFF.
State ③: Manual reset of alarm, "AL.14" cancellation.
State ④: "AL.15" warning is issued because 45 sec has elapsed since the circulating fluid
temperature deviated, because it is out of the temperature monitoring lower limit range.
"TEMP OUT" output ON.
State ⑤: Temperature monitoring enters the upper and lower limit range, "TEMP OUT" output OFF.
