1. Include
3 units main pumps & 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 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 and alarm control functions ect.
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 values, the
application will be more flexible.
11.when the inverter
get failure,The controller can choose the automatic 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 signal
use photoelectric isolation, strong interference ability .
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 )
