LINE LINE Caution: To avoid damage, do not exceed maximum allowable system pressure. Always check the pressure switch operation after re-setting. Adjustment Adjusting the operating pressure range of the,p/n 866, is accomplished by the Range and Differential spring nuts located under the pressure switch cover. The Range spring nut controls the cut-in or turn on pressure set point, while the Differential spring nut sets the operation cut-out or turn off pressure set point. Since the range adjustment changes both the high and low operating points, it is recommended to always adjust the Range spring nut first. Adjustment Instructions Set the switch pressure range by first removing the nut securing the pressure switch cover and remove the cover from the switch to access the adjustment spring nuts. Refer to the illustration shown to the right and adjust the pressure switch as follows: Range Adjust Range spring nut (A) until the desired operating point (cut-in) of 85 psi (5.8 bar) on falling pressure is obtained. Turning the Range nut (A) clockwise will increase the setting. Keep in mind the range adjustment changes both the high and low operating points but should always be adjusted for the low operating point. Differential Set the operating point (cut-out) on rising pressure to maximum by adjusting the Differential spring nut (B). Turning the nut (B) clockwise increases the pressure difference between the high and low operating points by increasing the high operating point only. Caution: To avoid damage, do not exceed maximum allowable system pressure. Always check the pressure switch operation after re-setting. Adjustment Adjusting the operating pressure range of the, P/N 869, is accomplished by the Range and Differential spring nuts located under the pressure switch cover. The Range spring nut controls the cut-in or turn on pressure set point, while the Differential spring nut sets the operation cut-out or turn off pressure set point. Since the range adjustment changes both the high and low operating points, it is recommended to always adjust the Range spring nut first. Adjustment Instructions Set the switch pressure range by first removing the nut securing the pressure switch cover and remove the cover from the switch to access the adjustment spring nuts. Refer to the illustration shown to the right and adjust the pressure switch as follows: Range Adjust Range spring nut (A) until the desired operating point (cut-in) of 80 psi (5.5 bar) on falling pressure is obtained. Turning the Range nut (A) clockwise will increase the setting. Keep in mind the range adjustment changes both the high and low operating points but should always be adjusted for the low operating point.. Differential Set the operating point (cut-out) on rising pressure to 0-psi (1. bar) maximum by adjusting the Differential spring nut (B). Turning the nut (B) clockwise increases the pressure difference between the high and low operating points by increasing the high operating point only. www.airtechniques.com Note: ground connection screws located on plate under wiring. RANGE SPRING NUT (A) ADJUST FOR CUT-IN POINT Adjust Sequence: 1. CUT-IN: Turn Range spring nut (A) clockwise for higher cut-in pressure. Turn counter-clockwise for lower cut-in.. CUT-OUT: Turn Differential spring nut (B) clockwise for higher cut-out pressure. Turn counter-clockwise for lower cut-out., P/N 866, Adjustment Location Note: ground connection screws located on plate under wiring. DIFFERENTIAL SPRING NUT (B) ADJUST FOR CUT-OUT POINT MOTOR MOTOR + P DIFFERENTIAL SPRING NUT (B) ADJUST FOR CUT-OUT POINT Adjust Sequence: 1. CUT-IN: Turn Range spring nut (A) clockwise for higher cut-in pressure. Turn counter-clockwise for lower cut-in.. CUT-OUT: Turn Differential spring nut (B) clockwise for higher cut-out pressure.
