■ About TEMP READY function
The operation chart of “TEMP READY” signal is shown in Fig. 5-6 TEMP READY signal
chart.
[Example of setting]
• (1) “High” Upper temperature limit: +2ºC and “Low” Lower temperature limit: -2ºC
• (2) “Ready Time” Stable temperature time: 300 sec and “Out Time” extra
temperature time: 200 sec
• (3) “Alarm Type” Alarm operation (AL12): “WRN”
• (4) “Start Time” Start time of alarm monitoring (AL12): 1000 sec
Fig.5-6 TEMP READY signal chart
Status (1): Start operation of the chiller.
Status (2): The temperature is in the "High/Low” range, but no “TEMP READY” signal is generated
since “Ready Time” is set at 300 sec at this point.
Status (3): The 300 sec count for “Ready Time” is reset since the temperature is now outside of the
“Low” range.
Status (4): The 300 sec count for “Ready Time” starts since the temperature is now within the
“High/Low” range.
Status (5): “TEMP READY” signal is generated at this point since the temperature remains in the
“High/Low” range for 300 sec of “Ready Time.”
Monitoring of “TEMP READY alarm (AL12)” starts at this point where 1000 sec of “Start
Time” has elapsed.
Status (6): “TEMP READY” signal output continues since the temperature is now back within the “Out
Time” range of 200 sec even though it was temporarily outside the “Low” range.
Status (7): “TEMP READY” signal turns OFF when 200 sec has passed after the temperature rises
above the “High” range. “TEMP READY alarm (AL12)” is simultaneously activated.
