Set the 'cut in' pressure point first. By turning the nut clockwise, the cut-in pressure is increased. 0000015481 00000 n Pressure switch, Manual adjustment The hydro-electric pressure switch type HED 8 is a piston type pressure switch. 11 0 obj 0000003090 00000 n Turn the nut clockwise to increase the pressure for both the cut-on and cut-off, 2 1/2 PSI for each rotation. Twist the nut clockwise for higher cut-in pressure or counterclockwise to reduce the pressure. Note just the bends and restrictions of plumbing will give enough back pressure to trigger 1 bar of pressure which is also the same amount a pressure switch is usually set to. Use a nut driver to twist the nut on the larger of the two springs on the pressure switch for adjusting the cut-in pressure, which is the pressure at which the pump activates. ISO 9001. Position 4 provides a manual reset on the low-pressure side and an automatic reset on the high pressure side. The non-adjustable pressure switches have fixed magnitude and you cannot adjust the pressure of this switch. 0000006073 00000 n ]2��SH���i�����9�������4�ЙjL��7p[�B��,t�6F:�v�R��|�̾x�m�B�"���ݧ�c��A�`Nʨ�G�k=���7֦�����X��Ľ����3�k�������uV�r�é�ZVnz�4���+�Y|*����#颦ێЛY���5�]]�M�J�����-ʵw%�w]�S����+�L�������E���D�&Q��,y��� *4�'U!KB�$���w��m��P���CA�-/8@�ʰS�Xͨ܅�Rjv�+L��P�ћ�|E��`�� =ևy�R_���K"]&3�Tun;�˧A��l�y��_T��ųw����I��O�Av� �u��Q�r�8�?�AYW��Q�Λ�t'�(�� l}�� ���ת <<49494C12D21DB2110A00FFF68030A6FF>]/Prev 216814>> Moving the screw counterclockwise will decrease both the pressures. 0000000016 00000 n UL Certification - Component Pressure Switche LF08. font-size: 13px; Adjusting the range can be done by following a few simple steps.

Worst & Company Inc. talks about stuff related to our industry! Remove the cover on your pressure switch. Pressure switches with two posts allow adjustment of the cut- on and cut-off pressure at the same time. The EPS40 and EPS120 Series supervisory pressure switches are intended for dry pipe systems or pressure t anks and water supplies of automatic water control valves. To increase or lower both cut-on and cut-off pressure you will turn the nut on top of the large center spring as seen in the picture below.

There are two types of pressure switches, one is adjustable and the other one is non-adjustable. The second post allows adjustment of the cut-off pressure independently. h�b``�b``ee```6�a@�@������!IT�D8r��x�?�y1�2�5�kpaP�m�u�%�!�V�Aԁ�Â,^160obpj�H`]���1���!��>PH�/�������=sV"�cd`6w�L@l�l̾�`q�M 1� Now that you have understood the principle behind the air compressor switch, it's time to take a look at the process of your air compressor pressure switch adjustment. Adjusting the Cut-In In order to increase or decrease the cut-in or the cut-out setting you will need to use a 3/8" nut driver or socket to adjust the switch, while still maintaining the same differential. High accuracy, stripped, up to 18,000 psi working pressure and 20,000 psi proof. A pressure switch will have a hysteresis, that is, a differential range around its setpoint, known as the switch's deadband, inside which small changes of pressure do not influence the state of the contacts. 0000015814 00000 n This is the range adjustment nut.
