Setup Data
Release [Factory setting]
Setting
Pump 34 : Freezing Prevention
ㆍ
It sets up freezing prevention mode.
ㆍ
It is to prevent pump from being broken due to low temperature (below zero) in winter using ambient temperature
sensor information within the drive.
The function is operated with a frequency not generating pressure between 0~10 seconds and maintained
as stopped status between 11~59 seconds based on 1 minute. This function is to prevent the pump from
freeze and burst by generating frictional heat upon rotation within pump casing.
This function is not for preventing freeze and burst of pipe.
Input Range
ID order [Factory setting]
In order of low watt-hour
Half pump
Pump 35 : Alternation method
ㆍ
It determines the order of Drive's run, stop, alternation on Multi-Drive operation mode.
ㆍ
As setting condition of ID order and watt-hour, pumps are rotated from low value.
Input Range Factory Setting
0.00 ~ 2.00 [bar] 0.30 [bar]
Pump 32 : Variation of Starting the Drive
ㆍ
It sets up pressure variance between Setting Pressure and Current Pressure for start of the Drive.
ㆍ
The Drive starts when the variance of pressure between setting pressure and current pressure has the
larger variance than the setting variance value.
Input Range Factory Setting
1~100 [sec] 5 [sec]
Pump 33 : Stand-by Pump Waiting Time on Multi-Drive Control Mode
This is to give some delay to stand-by pump. If the stand-by pump starts before the main drive output reaching
the maximum frequency, then the pressure may increase suddenly. On the other hand, in case the stand-by
pump stops without delay time, then the pressure would decrease drastically.
Input Range Factory Setting
5~100[%] 50 [%]
Pump 31 : Initial Output Rate on Starting
It refers to the minimum output ratio when the drive starts initially. That is, if it is set to 50%
when the maximum operation frequency is 60 Hz, it can start from 30 Hz.
Input Range Factory Setting
0~60[%] 30 [%]
Pump 30 : Stop-Rate of Drive
In case of a present pressure value is higher than a setting pressure value, a pump will be stopped if an
operation rate is below a stop-rate of a drive.
