【Temperature range monitoring function setting example 1】
[1] Circulating fluid temperature at start of operation: about 25°C
[2] Circulating fluid set temperature：15°C
[3] Temperature range monitoring function (upper limit)」： set to「20.0°C」
[4]「Temperature range monitoring function (lower limit）」：set to「10.0°C」
[5]「Monitoring of temperature range monitoring function」： Set to「rn.St」
[6]「Temperature range monitoring start time」： Set to「30sec」
[7]「Temperature range Time outside the monitoring range：Set to「45sec」
[8]「Output of NOT TEMP READY alarm」： 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: Operation start 30 sec elapsed, because the temperature monitoring upper and lower limits
have not been reached within the time range of monitoring the temperature range
"AL.14" is triggered. "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.
State ⑥: Since the temperature range is again within the monitoring
range, "AL.14" will not be reported and "TEMP OUT"Output OFF continues.
State ⑦: AL.14 report since 45 sec has elapsed since the circulating fluid temperature deviated,
because it is outside the upper temperature monitoring range. TEMP OUT output ON.
State ⑧: Since operation stopped, "TEMP OUT" output OFF.
