[CHAPTER 6 FUNCTION TABLE & DESCRIPTION]
6-9 | DOOCHPUMP
Pr-12 Start Variation
ㆍ
It sets up start variation pressure value. That is, the operation starts when the current pressure
has larger variance than the specified value comparing to setting.
ㆍ
In case of alarm occurrence, operation does not start.
Factory Setting Input Range
0.0 ~ 2.0[bar] 0.3[bar]
Pr-13 Stopping Time after Reaching Setup Pressure
ㆍ
When the pump pressure reaches to setting and maintained for longer than setup time, it starts to
reduce speed. If there is pressure difference as much as starting variation, the pump starts to
operate again during decrease of speed and if not, it stops.
ㆍ
Input Range : 5 ~ 200 [sec]
Factory Setting Input Range
5 ~ 200[sec] 30[sec]
Pr-14 Min Output Frequency Ratio to Stop after Reaching Setup Pressure
ㆍ
In order to stop after reaching to specified pressure, the drive is able to stop only if the current
minimum output frequency ratio is less or equal to setup ratio.
Input Range Factory Setting
0 ~ 100[%] 100[%]
Pr-15 Initial Output Ration on Starting
ㆍ
It refers to the minimum output ratio on starting of the drive. That is, if it is set to 50% when the
maximum operation frequency is 60 Hz, it can start from 30 Hz.
Factory Setting Input Range
5 ~ 100[%] 50[%]
Pr-40 485 Comm. Mode
ㆍ
To set up 485.
