Alternative Operation(basic)
After scheduled operating or when all of the pumps stop, the master pump will
alternatively change
- Alternative method means all of the pumps will run sequently.
- If all of the pumps stop and then reopertate, the master pump changes from pump one to
pump 2
-After passing the time of the Pr-54 (lead pump alternation time : Factory setting 12hour),
second pump will operate by force
Fixed Lead Pump Operation
In case the location is in demand of high water consumption or a location where the pump needs to maintain
contstant pressure.
-If Pr-54 (lead pump alternation time) is set at "0", the first pump will operate as lead pump
- The lead pump does not altenate, oand will operate sequently.
Method by Intergrated Current Rate
To operate by distributing the current evenly after calculating the intergrated
current from each controllers.
- If Pr-53 (Alternation Type)is set at "1", the pump with the lowest amount of
current consumed will operate.
ALL PID Method
Main controller controls all of the drives via PID
If Pr-61(PID control type setup) is set at "1", this function will be applied.
Operation Method

Check the product specification
Installation Place
Take the VFD out of the box, check the rating shown on a side of the product body to
determine wheather the VFD specification is what you had ordered. Check also whether
the product has been damaged during delivery. (refer to product components )
Booster system is usually installed indoors, but if the system is installed outdoors, there should be covers to
protect the electronic components from water, freezing and natural disaster
Booster pump systems have to be installed within a pressurization condition.
To prevent the suction pipe from any dust, please install extra strainer
To prevent dry-running, make sure the water level is always higher than the pump. Make sure
the pump has been installed to keep the minimum suction pressure.
To prevent flood damage from installation, pump breakage, leakage by external condition,
please install within a facility that is equipped with drainage.
The pump installation shall not allow the system pipeline tensile force to be transferred to
the suction and discharge pipe.
Suction pipe line should be installed less curved and short.
To be convenient maintenance, encourage to install By-pass(discharge), valve and flexible
joint to suction and discharge pipe.
Please install the prevention device for Water Hammer to discharge sector. If suction pipe is
over 10m and covered 2 times, the chage of dicharge pressure can occure and low water
level switch can operate, so suction pipe line should be larger than booster system manifold.
Pipe Line
Wiring
Wiring should be performed by an wiring expert. To prevent from electronic leakage by
inductance and electronic shock , circuit breaker and grounding should be installed.
Main wiring for booster pump has already been wired in the factory. If you need additional wiring,
please wire as per the electronic drawings .
Note before operating
- Is the circuit breaker capacity enough ?
- is the wiring correct ?

Initialization Code

Enter the maximum value that the pressure sensor can measure.
By entering capacity of pressure sensor attached to the drive being used, it is possible
to display the currently measured pressure.
Example) In case the using sensor has 10bar, enter 10.0.
If the using sensor has 16bar, enter 16.0.
And enter the rated value of the pressure sensor for normal pump operation.
Pr-03 : Sensor 1 Capacity Setup
It corrects pressure variation between analog or digital pressure meter and the one
displayed on drive FIND.
Pr-04 : Sensor 1 Correction Setup
It sets up freezing prevention mode of pump.
It is to prevents 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.
Pr-11 : Freezing Prevention Function
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.
In case of alarm occurrence, operation does not start.
Pr-12 : Start Variation
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.
