The PXP2.3 will automatically modulate its control valve(s) to regulate the branch line pressure to the selected set point as determined by the input signal. The PXP2.3 o ers four selectable input ranges which convert to a 0 to 15 psig modulating output (See EPC product for 0 to 20 psig outputs). A 0-5 VDC feedback signal indicating the resultant branch line pressure is also provided. This signal varies linearly with branch pressure (0 volts= 0 psig, 5 volts = 15 psig). The PXP2.3 incorporates two valves and does not use air at set point. It’s branch exhaust ow and response time are not limited by an internal restrictor and are similar to its load rate. If power fails to the PXP2.3, branch line pressure remains constant if the branch line does not leak air. The PXP2.3FS is equipped with a N.O. branch exhaust valve which allows exhaust of branch air on power failure. A manual override (jumper selectable), which controls the output pressure, is provided for setup and troubleshooting. MOUNTING INSTRUCTIONS Circuit board may be mounted in any position. If circuit board slides out of snap track, a non-conductive “stop” may be required. Use only ngers to remove board from snap track. Slide out of snap track or push against side of snap track and lift that side of the circuit board to remove. Do not flex board or use tools. WIRING INSTRUCTIONS PRECAUTIONS • Remove power before wiring. Never connect or disconnect wiring with power applied. • When using a shielded cable, ground the shield only at the controller end. Grounding both ends can cause a ground loop. • It is recommended you use an isolated UL-listed class 2 transformer when powering the unit with 24 VAC.

The cathode, or banded side of the DC Transorb or diode, connects to the positive side of the power supply. Without these snubbers, coils produce very large voltage spikes when de-energizing that can cause malfunction or destruction of electronic circuits. • All wiring must comply with all local and National Electric Codes. The gauge port will accept a miniature 1/8”-27 FNPT back-ported pressure gauge to allow direct reading of branch line pressure. The gauge should be sealed by Te on sealing tape, and should be tightened just snug, using a backup wrench to hold the manifold. ADJUSTMENT OF INSTALLED GAUGES. If installation requires adjustment of the gauge for proper reading of the face, turn the gauge no more than ½ turn in either direction. O-rings in the bottom of the gauge port will allow this without leakage. Warranty does not include malfunction due to clogged valve. Main air port is ltered with the supplied 80 – 100 micron integral-in-barb lter (except for the PXP2.3LG model). Periodically check the lter for contamination and ow reduction. Replace if needed (Part # PN004). The surface between the manifold and pressure transducer is a pressure seal. Minimize stress between the circuit board and the manifold by holding the manifold in one hand while installing pneumatic tubing onto the ttings, and use care when removing tubing to avoid damaging ttings or moving manifold. This unit requires at least two cubic inches (minimum) of branch air line capacity to operate without oscillation. Do not operate without main air supplied.

Verify the MAN/AUTO jumper shunts are in the AUTO position (jumper over center pin and AUTO pin). In AUTO, the manual override pot is inactive and the analog input signal is supplying the set-point. When in the MAN position, the manual override pot in supplying the set point and the analog input signal is locked out. Use a small bladed screwdriver to increase or decrease the pneumatic output. Supply power and the LED power indicator will light, but only measurement will verify proper voltage. Apply minimum and maximum input signals and measure response. Response between the minimum and maximum values will be linear, therefore software algorithms are easy to derive. The feedback signal range on all selections is 0 to 5 VDC and is proportional to the output pressure range of 0 – 15 psig. The output and feedback signal will continue to vary proportionally if the input signal is increased beyond its upper limit (if there is enough main air available). However, do not exceed the listed maximum input signal voltage by more than 25%. The PXP2.3 incorporates two valves and is not a constant bleed controller. Its branch exhaust ow and response time is not limited by any internal restrictor and is similar to its load rate. The PXP2.3 is ideal for long branch line runs, multiple actuators, and outside air dampers because of it’s 750 scim capacity. Note: If power to the PXP2.3 is lost, it will maintain branch line pressure (assuming no branch line leaks). If power to the PXP2.3FS (Fail-Safe) is lost, the branch line control valve will open and branch line pressure will go to 0 psig.
