SSNS-103 SSNS-106 SSNS-110 SSNS-120 SSNS-130 Electronic Pressure Differential Controllwer Automatic Pressure Switch For Air Compressor Water Pump Controller Valve

1.Connection and installation method



a) Connection Mode: There are two connection modes for the controller: one is the outer diameter Φ "A 6x1 copper tube (must be in a soft state), with a 90 ° bell opening at the tube end, can be tightened with the controller's own nut. Another connection method is to use a capillary tube with an outer diameter of O3 and a length of 1 meter (This connection method must be proposed when ordering)"



b) Installation Method: There are two installation methods for the controller: one is to use the four M4 mounting screw holes on the back of the controller for installation. Another installation method is to select multi-purpose mounting plate accessories.



2. Instructions



Installa: a.If the capillary tube is used for connection, it is necessary to prevent sharp bending and twisting of the capillary tube.

b. If the controller is used in a refrigeration system using ammonia as the medium, the model of the stainless steel bellows controller must be selected (that is, add A after the modelIndicate when ordering).

c. Before connecting to the controller, ensure that all pipelines are clean and clean.

d. The controller cannot be installed in equipment with a working load exceeding its electrical rating.

e. The excessively long capillary tube is coiled or properly fixed to prevent vibration. Allow the capillary tube to sag slightly to prevent cracking due to severe vibration.

f. When connecting the connecting pipe, it is necessary to use two 10 inch wrenches to tighten the nut and joint of the controller at the same time to avoid damaging the controller components.

Wiring adjustment: When opening the enclosure to prepare for wiring, it is necessary to ensure that the power supply is cut off to prevent electric shock and equipment damage.



Wiring Adjustment

a. Turn the pressure adjusting screw clockwise to decrease the pressure setting value, otherwise, it will increase.

b. Turn the pressure adjusting screw clockwise to increase the set value of the differential pressure, otherwise, it will decrease.
