How to set

1.Adjust pressure upper limit

A),Short press left key,  show  pressure  upper  limit.

Then long press left key 2 seconds, LED show‘PUP’,

go to pressure upper limit adjust.

B),Short press left key=plus 0.1,

    long press left key=plus 1.0.;

C),Short press right key=minus 0.1,

    long press right key=minus 1.0;

D),Automatically exit after 3 seconds, go to current

displayed pressure.

2.Adjust pressure lower limit

A), Short press right key,  show  pressure lower limit.

Then long press right key 2 seconds, LED show‘pdn’,

go to pressure lower limit adjust.

B),Short press left key=plus 0.1,

    long press left key=plus 1.0.;

C),Short press right key=minus 0.1,

    long press right key=minus 1.0;

D),Automatically exit after 3 seconds, go to current

displayed pressure.

3,The power voltage display

A)Long press left key 2 seconds, LED show ‘Vol’, go to show the current power voltage.

B)If long press right key 2 seconds, LED show ‘Vdd’, go to show PCB DC voltage.

C)Short press left key or right key, you can exchange the state of  A) and B).

D)Automatically exit after 3 seconds, go to current displayed pressure.


A)Press left key above 5 seconds, you can run or stop the pump.

B)If press right key above 5 seconds, the pump is off, LED shows ‘OFF’and cancel countdown.5.

5,Child Lock

Long press double key 2 seconds, the pressure switch is locked and can’t amend parameter.

The last decimal point shining.

Long press double 2 seconds, remove locked.


A)Press double above 5 seconds, LED shows‘tHt’, go to adjust countdown.

B)Short press left key=plus 0.1 hour=6 minutes. Long press left key= plus 1.0 hour.

CShort press right key= minus 0.1 hour. Long press right key= minus 1.0 hour.

D)Time is over, you can stop or run pump. If you stop pump, will show ‘OFF’.

E)Press right key above 5 seconds, countdown will cancel. The pump is off ,and show ‘OFF’.

Warning information

1.‘12.3’ or‘4.5’or‘P6.7 = current pressure display format, unit kg/cm².

2.‘EUH’ means Error High voltage, power voltage is greater than 265Vac.It is safer.

3.‘EUL’ means Error low voltage, power voltage is less than 145Vac.It is safer.

4.‘SEn’ means Senscr Error. It will stop.

5.‘PLO’ means Low Pressure.

6..‘dry’ means real dry. It is no water safly. If you want to run the pump, you will run manually.

7.‘HZO’ means no water. The pump will restart within 5 minutes if no water.

8.‘OFF’ means turn off.

9.‘SPH’ means deadhead. The pressure can’t reach upper limit. The pump will stop.

10.‘t1.2’ means timer, unit is hour. Also the pressure shows double digit, unit Bar,

For example ‘P3.4’.

Q:Mold temperature switch on how to adjust the size of the switch
Adjust the middle of the nut, and eyes look at the degree, clockwise or counterclockwise to adjust the appropriate pressure in the middle.
Q:Pressure switch precautions
Pressure switches are widely used in household, commercial, automotive refrigeration systems for high and low pressure protection control, steam conditions and power stations; accumulators, receivers, flash tanks, separators, scrubbers, oil refineries. It is also suitable for high and low pressure protection control of various equipment tools. But in the choice of pressure switch, we should note the following: 1. The need for explosion-proof: explosion-proof form is divided into flameproof and intrinsically safe, Nagano products for the majority of flameproof. 2. Need to indicate: according to customer instructions. 3. Number of contacts: one contact (one output) or two contacts (two outputs). 4. Determination of the set value and pressure range: The recommended setting range is between 30% and 65% of the pressure range, which can be set between 15% and 90% of the pressure range. 5. The form of splicing: adjustable or fixed. 6. Whether there is pulsation: If the pressure is pulsating or vibration, need to bring the throttle to suppress the pulse pressure on the instrument damage. 7. With the diaphragm of the occasion: the determination of corrosive, high viscosity or temperature is too high, the need to use with a diaphragm. Turn left to turn right
Q:About how the pressure switch and the pump control box are connected
General pressure sensors are 12V to 24 wide range of power supply, the sensor has 2-wire and 3-wire system.
Q:No - name intelligent electric pressure cooker failure code
Clean; the second case you have to adjust the pressure switch, as follows: Adjusting method of pressure switch for electric pressure cooker There are two methods, 1. hand pressure gauge: add appropriate amount of water to the pot, cover the lid to boil, remove the pressure relief valve marked pressure gauge, etc. table readings rose to 0.068MP when the pressure switch to adjust it just off; with glue fixed adjustment screw. 2. There is no pressure gauge on hand, do not remove the unloading pressure valve, the first pressure Force to the maximum, and other relief valve just began to leak, immediately adjust the pressure switch to jump, and then clockwise and then spin a little bit on the line. Remember to have to Fix the screws with glue.
Q:Pump pressure switch 0.3 stop, 0.1 start. Want to tune to 0.3 stop, 0.2 start how to tune?
I also want to buy this pressure switch, if it is online to buy, can give a shop?
Q:Pressure switch and electromagnetic valve operating principle
what! Upstairs that is too professional, it is necessary to design these devices to understand the talent. Popular pressure switch is quite a button switch is only the power of your original finger on the pressure we need to test to complete the need to complete. Electromagnetic commutation method, but in this it is provided by the external device to control the power to complete, and perhaps this control device is said before the pressure switch.
Q:Air compressor pressure switch, pressure and pressure is how to tune
First set the pressure on the pressure switch above the pressure set, and then adjust the pressure difference under the adjustment of the pressure difference.
Q:Gas switch is open or off ah
Is open in general, this common cut-off valve parallel to the pipeline is open state, perpendicular to the pipeline is off state.
Q:What is a double contact pressure switch
With a pressure switch with a normally open or normally closed contact output
Q:How to calculate the allowable error of the pressure switch
Occupational examination questions in the operating questions are: pressure switch to allow the error = ± pressure switch set value × precision level%, of which the accuracy level is generally 1.5
