Setting for low flow rate alarm threshold
6.
Press the [▼] key. Displays screen for setting low flow rate alarm threshold.
The user can change the threshold of "AL10
low flow rate
".
●
Setting range
：
3.0 to 15.0 LPM(
Initial value
：
4.0 LPM)
Detection time for low flow rate alarm
7.
Press the [▼] key. Displays screen for setting the detection time of the low flow rate
alarm.
When the circulating fluid flow rate is below the threshold for this set amount of time alarm
"AL10 low flow rate" is generated. The detection time can be set in the range shown below.
●
Setting range
：
0 to 600 sec(
Initial value
：
5 sec)
Setting for electric conductivity rise alarm
8.
Press the [▼] key. Displays screen for setting value of
electric conductivity rise alarm
threshold.
Displayed only when Option DM is selected [Electrical conductivity control function , DI
water (pure water) piping].
The user can change the threshold of "AL12
electric conductivity rise
."
●
Setting range
：
5.0 to 45.0 µS/cm(
Initial value
：
45.0 µS/cm)
Setting of NOT TEMP READY alarm
9.
Press the [▼] key. Displays screen for changing the chiller behaviour when the NOT
TEMP READY alarm occurs.
The user can decide the chiller behaviour if alarm "AL13: NOT TEMP READY" occurs.
