The PXP2.3 willautomatically modulate its control valve(s) to regulatethe branch line pressure to the selected set point asdetermined by the input signal. The PXP2.3 offers fourselectable input ranges which convert to a 0 to 15 psigmodulating output (See EPC product for 0 to 20 psigoutputs). A 0-5 VDC feedback signal indicating theresultant branch line pressure is also provided. Thissignal varies linearly with branch pressure (0 volts= 0psig, 5 volts = 15 psig). The PXP2.3 incorporates twovalves and does not use air at set point. It’s branchexhaust flow and response time are not limited by aninternal restrictor and are similar to its load rate. If powerfails to the PXP2.3, branch line pressure remainsconstant if the branch line does not leak air. ThePXP2.3FS is equipped with a N.O. branch exhaust valvewhich allows exhaust of branch air on power failure. Amanual override (jumper selectable), which controls theoutput pressure, is provided for setup andtroubleshooting.MOUNTING INSTRUCTIONSCircuit board may be mounted in any position. Ifcircuit board slides out of snap track, anon-conductive “stop” may be required. Use onlyfingers to remove board from snap track. Slideout of snap track or push against side of snaptrack and lift that side of the circuit board toremove. Do not flex board or use tools.WIRING INSTRUCTIONSPRECAUTIONS• Remove power before wiring. Neverconnect or disconnect wiring with powerapplied.• When using a shielded cable, ground theshield only at the controller end. Groundingboth ends can cause a ground loop.• It is recommended you use an isolatedUL-listed class 2 transformer when poweringthe unit with 24 VAC.
