The PS40 switch is factory set for 40 PSI (2,8 BAR) <br />normal system pressure. The switch marked with the word LOW is set to <br />operate at a pressure decrease of If PSI (,7 BAR) at 30 PSI (2.1 BAR) The <br />switch marked with the word HIGH is set to operate at a pressure increase <br />of IOPSI(,7BAR)at50PSI(3,5 BAR) See section heading Adjustments <br />and Testing Bother dim factory set point is required <br />I. Connect the PS40 to the system side of any shutoD'or check: valve. <br />2.

Connect the wires to the appropriate terminal connections for the <br />service intended. See Figures 2,4,5.6, and 8 <br />Adjustment And Testing <br />The operation of the pressure supervisory switch should be tested upon <br />completion of installation and periodically thereafter in accordance with <br />the applicable NFPA codes and standards and/or the authority having <br />jurisdiction (manufacturer recommends quarterly or more frequently). <br />Note Testing the PS40 may activate other system connected devices <br />The use of a Porter BVL (see product bulletin 8900067 for details) is <br />recommended to facilitate Bening and testing of the P540 pressure switch. <br />When a BVL (bleeder valve) is used, the pressure to the switch can be <br />isolated and bled from the exhaust port on the BVL without effecting the <br />supervisory press= of the entire system. See Fig. 3 <br />The operation point of the PS40 Pressure Switch wit be adjusted to any <br />point between 10 and 60 PSI R7 - 4.11 BAR) by turning the adjustment <br />knob(s) clockwise to raise the actuation point and counter clockwise to <br />lower the actuation point In the case of the PS40.2, both $%ouches operate <br />independent of each other. Each switch may be independently adjusted to <br />actuate at any point acrosss the switch adjustment range Initial adjustment <br />can be made with a visual reference from the top of the adjustment knob <br />across to the printed scale on the switch bracket. Final adjustments should <br />be verified with a pressure gauge. <br />Potter Electric Signal Company, LI-C St. Louis, MO • Phone866.956-0988/Canada 888.882-1833 • wwsvw pouersignal.com <br />PRINTED IN USA MFG=:a00930-REV E PAGE I OF 3 <br />09/I7 <br />�,,L 31 <br />
