- A ！ Pressure switch is powered by an external power supply. The power supply should be in accordance with relevant standards stipulated by energy limitation circuit, and special attention should be given to the high-voltage that may exist in the circuit. 

Two pressure switches can be used to create a differential measurement system, commonly used in the filter control or closed container level measurement. Install pressure transmitter 

Can be installed with adapters on the pipe directly. 

Light-weight pressure switch can be mounted directly on the pressure leading tube. When installing the maximum torque force can not exceed 50Nm. 

- AX ！ 

After the pressure  vessel is stable, slowly open the shut-off valve to in start measuring. 

Can be used for liquid level measurement in open container. Media compatibility should be considered.

   - A zero point adjustment should be made after installation to counter any effects the mounting position may have on the zero setting. 

   - When performing the adjustment, the vessel should be completely empty, with no pressure or media on the measuring diaphragm and the vessel exposed to atmospheric air. 

   - With unit powered, short the key-z wire (blue) to the + power lead. hold for 5 seconds, when removed the zero point will be adjusted. Set the zero point three weeks after installation to ensure accuracy, and reset zero point annually. 

   - Set PV=0 each year.

- /£\ ！ The signal connection of 4~20mA + two way NPN output is similar 

- Keep dry and dust-free. 

- Do not expose to the corrosive medium. 

- Avoid solar radiation. 

- Avoid mechanical shock and vibration. 

- Storage temperature: -40-185℉(-40-85℃).

   - Maximum relative humidity: 95%. 

   - EMC equipment instructions 2014/30/EU. 

   - CE mark suggests the instruments are in line with EU standards 

   - Users need to ensure the whole equipment conform to all the applicable standards. 

- Standard current signal output+transistor output: 12-30VDC, 

- Transistor output: 12-30VDC. 

- A cable with a shielded twisted-pair signal is recommended to avoid ground loop. 

- The built-in transient resistance module is only effective if properly grounded. The metal body and internal grounding terminals should be directly grounded. 

To safeguard against liquid media potentially traveling along the cable into the terminal box, the cable should be configured in a U-shape as shown, with the bottom of the “U” lower than the bottom of the pressure switch.

Notes: 1. x =1 or 2, SPx ≥ RPx 

2. Active electrical level is 2V lower than power supply level. Eg, power supply level is 24V, then active electrical level is 22V.

## High level alarm 

Output alarm signal when pressure is higher than 145Psi. Normal setting: SP1=145Psi, RP1=137.78Psi, Mode1=1, SPDT1=1, RPDT1=1. Pressure rises to 145Psi, delay 1s, OUT1 active (on); pressure drops to 137.78Psi, delay 1s, OUT1 reset (off) 

## Low level alarm 

Output alarm signal when pressure is lower than 145Psi. Normal setting: RP1=145Psi, SP1=152.28Psi, Mode1=2, SPDT1=1, RPDT1=1. Pressure drops to 145Pssi, delay 1s, OUT1 active (on); pressure rises to 152.28Psi, delay 1s, OUT1 reset (off) 

## Window function 

Starting devices normally requires pressure is within the range 72.51~145Psi. Normal setting: SP1=145Psi, RP1=72.51Psi, Mode1=3, SPDT1=1, RPDT1=1. Pressure rises to 145Psi, delay 1s, OUT1 active (on); pressure rises to 145Psi, delay 1s, OUT1 reset (off); Pressure drops to 145Psi, delay 1s, OUT1 active (on); pressure drops to 72.51Psi, delay 1s, OUT1 reset (off) 

## Automatically keep pressure function 

Applying pressure on a device by a compressor and keeping the pressure within the range 72.51~145Psi need two ways output. The first way output controls the compressor and the second way output controls the device. The first way output setting: SP1=130.53Psi, RP=87.02Psi, Model=2, SPDT1=1, RPDT1=1. The first way contact controls the power supply of compressor through intermediate relay to disconnect once the pressure is higher than 130.53Psi and connect once the pressure is lower than 87.02Psi. The pressure value needs to be controlled within 87.02~130.53MPa. The second way output setting: SP2=145Psi, RP2=72.51Psi, Mode2=3, SPDT2=1, RPDT2=1. Once the working pressure of device is not within the range 

72.51Psi~145Psi, after 1s, the second way contact controls the alarm output of  the device through intermediate relay to ensure the abnormal working pressure of the device can be discovered and handled in time. 

Display module is used for field adjustment to complete all the parameters setting and site configuration before measuring. 

For example, factory setting parameters: pressure range -10-100Psi, display unit Psi, operate in the atmosphere.

Note 1: By default, the system shows optimal precision according to measuring range. Eg: While the measuring range of product is 0-10kPa, measuring value shows 0.000-10.000; while the measuring range of product is 0-100kPa, the measuring value shows 0.00-100.00. If DotPos parameters value and measuring range do not match, the system will automatically ignore and then process by default. 

Eg: While the measuring range of product is 0-10kPa, if operator makes DotPos=5, the system will regard it as ineffectiveness and the measuring value will still shows 0.000-10.000 by default; while the measuring range of product is 0-100kPa, if operator makes DotPos=4 or 5, the system will regard it as ineffectiveness and the measuring value will still shows 0.00-100.00 by default. 

Note 2:Use FixCOut parameters to control fixed current ,to confirm whether current output is ok. Changing fixed current value by press S and confirm by Z. 

Note 3:Use FixTOut parameters to control 2 way PNP by mannual operation, to confirm whether PNP output is ok. Changing fixed current value by press S and confirm by Z.
