    long press right key=minus 1.0;

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

displayed pressure.

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.


4,ON/OFF

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.

6.Countdown

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:What is the role of the fire engine pressure switch?
The input module, which is called a monitoring module, is used to detect the working status of the equipment. It is usually monitored to use the normally open signal device. Once the device is being monitored and normally closed, the alarm information of the device action is sent to the host.    Pressure switch: When the alarm valve action, alarm pipe water, tube pressure is greater than the set value, the switch action, to the system feedback alarm valve work.    Signal valve: In order to avoid misuse of personnel, resulting in the valve closed, the system can not work, so the valve installed on the signal feedback device to avoid misuse
Q:Home booster pump water control automatic switch how maintenance
Flow switch failure. May be stuck by the garbage in the water. Remove the rinse. Or replace the water flow switch.
Q:Pressure switch and electrical contact pressure gauge principle are what
There are many principles of pressure switch, such as piston type, spring type, electronic and so on.
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:How does the air conditioning pressure switch check?
Four lines! One of which is the Ac request signal line 12v one is to the ECU! System refrigerant is sufficient, they are interlinked! For high voltage switch! It is broken ECU can not receive Ac signal, the compressor will not start! One is to take the wire! One is the ECU in the pressure detection line 5v! System refrigerant is interlinked when sufficient!
Q:How does air conditioning pressure switch know bad?
Automotive air conditioning pressure switch power supply by the three-state switch from the 3-pin switch into the switch, through the internal series of high-voltage switch and low-voltage switch from the 1 # feet output to the air conditioning controller and compressor relay. Three-state switch 4 # feet connected to the iron, after the pressure switch from the 3 # pin output high-speed fan request signal to the engine computer, both pressure greater than 1.77MPa when the condenser fan high-speed turn, less than 1.37MPa condenser fan low speed The
Q:Air compressor in the off pressure, closing pressure, what is the meaning of how the pressure switch pressure switch.
Because the air compressor is a pressure factor automatic control switch, disconnect pressure is to reach this pressure, the air compressor does not work or no output, should be the highest value.
Q:Pressure switch normally open and normally closed in the end is what meaning
The pressure switch is a simple pressure control device, when the measured pressure reaches the rated value, the pressure switch can issue an alarm or control signal. The working principle of the pressure switch is: when the measured pressure exceeds the rated value, the free end of the elastic element displacement, directly or after comparison to push the switching element, change the switching element on and off state, to control the measured pressure purposes.
Q:Car air conditioning compressor pull, but the fan does not turn, with the pressure switch has a relationship? why?
There is a relationship, but also to see what car, some car compressor is variable, when are the pull, pull does not mean that work. Models are not the same, there are many kinds of compressors.
Q:Fire mainframe display pressure switch regulation is going on
The pressure switch is monitored by the monitoring module to monitor whether the pressure switch is active. If the pressure switch is activated, the monitoring module will be subject to the input signal, and the supervisory event will be displayed on the host. This is only the working principle
