Main features:
ZHG-9603 series constant pressure water supply controller is
specialized for constant pressure water supply pump
Variable frequency controller.the constant pressure water supply
controller can make the water supply system run
Steadily and reliably, and realize a true automatic cycle pump and
variable frequency operation, to ensure the optimal
Running efficiency of each water pup and the stable operation of
the equipment start smoothly. Eliminates high-current
Shooks and lowers the pump's average speed, extending pump life and
eliminating water hammer during startup and
Shutdown.
1. Include 3 units main pumps and one unit small pump, it has
multiple controlling mode and meets all kinds of complex
Requests of water supply.
2. Timing change pump function, balance all kinds of pumps' working
time, improve the average of life of the pumps.
3. up to 8 periods pressure control, and each period can be set any
pressure setting control and realize the timer
on/off function.
4. Sleep function and auxiliary small pump function, save energy
and reduce consumption, extend machine's life.
5. Positive and negative feedback function, can be used for water
supply, but also can be used to pump water and
Maintain the water level.
6. over-pressure, low water level, sensor disconnection, inverter
failure an alarm control function et.
7. Feedback can connect with passive remote pressure gauge, active
voltage and current transmitter.
8. Feedback device power 0-24v can be modified, stronger
commonality.
9. Feedback signals can be selected, it is more convenient to
connect with outer.
10. Standard 0-10v voltage output, can also be arbitrarily modified
to other voltage value and current transmitter.
11. When the inverter get failure, the controller can choose the
qutomatic transfer to the working frequency running
(pressure range control).
12. Relay fault output function can be selected.
13. Strong adaptable, applicable to various brands frequency
inverter at home and abroad.
14. All digital use photoelectric isolation, strong capacity of
resisting disturbance.
15. with complete key function.

For the setting method of the controller, Please see page 6 and 7
of the manual. The working mode is shown in the following parameter
settings:
For example:Meter range is 1.6Mpa, users request is set to 1Mpa
constant pressure, the controller will start if pressure <
0.6Mpa.
| 1,One inverter run with one motor,The parameters are set as
follows: |
| The setting pressure: | F000=1.00 |
| over-pressure alarm pressure: | F004=1.30 |
| Meter range: | F012=1.60 |
| Sleep frequency: | F029=30.0 |
| Wake-up pressure width: | F031=0.40 <(F000-F031=0.60this pressure wake up, it will start
the inverter. |
| Pump 2 property: | F042=0 |
| Pump 3 property: | F043=0 |
| |
| 2,One Inverter run with two motors . parameter are set as below: |
| The setting pressure: | F000=1.00 |
| Over-pressure alarm pressure: | F004=1.30 |
| Meter range: | F012=1.60 |
| Increase pump pressure threshold width: | F022=0.05 <(F000-F022=0.95Mpa)the pressure wake up, and
frequency up to 50HZ, to add pump after deferring |
| Reduce pump frequency: | F025=35.0 |
| Sleep frequency: | F029=30.0 |
| Wake-up pressure width: | F031=0.40 <(F000-F031=0.60)the pressure wake up. start the
inverter. |
| Pump 3 property: | F042=0 |
| |
| 3,One Inverter run with three motors. parameter are set as below: |
| The setting pressure: | F000=1.00 |
| Over-pressure alarm pressure: | F004=1.30 |
| Meter range: | F012=1.60 |
| Increasing pump pressure threshold width: | F022=0.05 <(F000-F022=0.95Mpa) the pressure wake up, and
frequency up to 50HZ, to add pump after deferring. |
| Reduce pump frequency: | F025=35.0 |
| Sleep frequency: | F029=30.0 |
| Wake-up pressure width: | F031=0.40 <(F000-F031=0.60)less than awaking .Run VFD. |
Small Pump setting as below:
With auxiliary pump:
Small pump starting pressure width:F034=0.08 equal
(F000-F034=0.92), sleep status,small pump will start if less than
the pressure.
Small pump stop pressure width:F035=0.05 equal(F000+F035=1.05),at
sleep status,small pump will stop if bigger than the pressure.
Without auxiliary pump:
F033=0; (also can remain and do not change )
