The PXP*.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 PXP*.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 PXP0.3 is a single valve version that does not bleed or exhaust air. Its operation depends on the pneumatic circuit where it is installed to consume between 14 and 73 scim. The PXP1.3, 5.3, and 7.3 are constant bleed controllers with branch exhaust response time determined by the bleed ori ce size and pressure di erentials (see ordering grid on the next page). If power fails, the PXP1.3, 5.3, or 7.3 will continue to bleed through the bleed ori ce until branch pressure is zero psig. 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. 3.25” (82.55mm) 2.18” (55.37mm) PXP 0.70” (17.78mm) 2.18” (55.37mm) 2.70”(68.58mm) PXP With Gauge 3.25” (82.55mm) 2.18” (55.37mm) Ø1.64” (41.66mm) 2.95” (74.90mm)FIGURE 3: SHUNT SWITCHES FIGURE 2: WIRING Automation Components, Inc. 2305 Pleasant View Road | Middleton, WI 53562 Phone: 1-888-967-5224 | Website: workaci.com Page 2 Version: 5.0 I0000488 WIRING INSTRUCTIONS (Continued) • It is recommended you use an isolated UL-listed class 2 transformer when powering the unit with 24 VAC. Failure to wire the devices with the correct polarity when sharing transformers may result in damage to any device powered by the shared transformer. • If the 24 VDC or 24VAC power is shared with devices that have coils such as relays, solenoids, or other inductors, each coil must have an MOV, DC/AC Transorb, Transient Voltage Suppressor (ACI Part: 142583), or diode placed across the coil or inductor. 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. Periodically check the lter for contamination and ow reduction, and clean with a brush or 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.

Do not lose the sealing gasket or insert anything into the precision bleed ori ce. Clean by swabbing with a degreaser and blowing clean air through the ori ce from the opposite direction. The color of the hex nut indicates the size of the ori ce: brass=0.007”; silver=0.010”; copper=0.005”. 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. CHECKOUT Select one of the four input/output signal combinations by moving the jumper shunt (see Figure 3 (p. 2)). 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. 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 PXP1/5/7.3 are constant bleed controllers and utilize a precision bleed ori ce to maintain a measured ow of air across the valve. The PXP0.3 does not have a bleed ori ce and depends on a continual pneumatic system branch bleed of 14 to 73 scim. Use the PXP0.3 when the downstream system includes pneumatic components that continually exhaust air. For proper operation, combined exhaust air ow (PXP ori ce loss and branch system loss) must be between 14 and 73 scim. The branch exhaust response time is determined by the combined exhaust air ow as well as pressure di erentials. If power to the PXP1/5/7.3 is lost, it will continue to bleed through the ori ce until branch pressure is zero psig. To use the manual override, place the AUTO/MAN jumper shunt in the MAN position. The potentiometer is now operable, and using a small bladed screwdriver, you may increase or decrease the pneumatic output.
