UE switch debugging method
1. Connect the multimeter to the output wire;
2. Unscrew the screws on the top of the controller;
3. Add the positive and negative pressure difference to 0.15 MPa, which can be read from the standard pressure gauge;
4. Loosen the set screw;
5. Use a slotted wrench to turn the hexagonal groove of the set value adjusting screw clockwise to make the set value change from small to large until the switch contact switches at 0.15 MPa;
6. Adjust the pressure of the calibration bench to change up and down at 0.6MPa, and check whether it is 0.15Mpa when the pressure drops. This value is the lower switching value to be set. The corresponding upper switching value is 0.16-0.17MPa;
7. Tighten the set screw.
8. Commissioning completed
Technical parameters of 400 series pressure switch
Storage temperature: - 54 to 71 ℃;
Ambient temperature: - 50 to 71 ℃; When the ambient temperature changes by 28 degrees, the typical drift value of the set point is less than 1% of the full range;
Set point repeatability: temperature switch: plus or minus 2% of the adjustable range;
Pressure switch: 126-376, 50-535540-547570-572, S126-S164B is plus or minus 2% of the adjustable range; 550-559 is plus or minus 1% of the adjustable range; 610-614 model is plus or minus 3% of the adjustable range;
Impact resistance: after 10ms and 15G impact test, the set point can be reproduced;
Anti vibration: after 2.5G and 5500Hz vibration test, the set point can be reproduced;
Enclosure class: NEMA 4 requirements;
Switch output: one, two or three SPDT outputs; * * * can be set separately within the adjustment range; 521-524531-534 type: 50%; 520,525,530,535,570-572: 30% The switch can be normally open or normally closed.
