POWER CONNECTIONS - THIS PRODUCT ACCEPTS 24 VOLTS AC OR DC POWER.

Be sure to follow all local and electrical codes. Refer to wiring diagram for connection information.
1) The secondary supply voltage to the interface should be isolated from earth ground, chassis ground, and
neutral leg of the primary winding. Any field device connected to this transformer must use the same common.
If you are not sure of other field device configuration, use separate transformers. Failure to follow these
procedures can result in improper operation.
2) If the 24 volt AC power is shared with devices that have coils such as relays, solenoids, or other inductors,
each coil must have an MOV, AC Transorb, or other spike snubbing device across each of the shared coils.
Without these snubbers, coils produce very large voltage spikes when de-energizing that can cause
malfunction or destruction of electronic circuits.
3) If the 24 volt DC power is shared with devices that have coils such as relays, solenoids, or other inductors,
each coil must have an MOV, DC Transorb, or a diode placed across the coil or inductor. The cathode or
banded side of the diode (or DC Transorb) connects to the positive side of the power supply.

4) You should measure the actual voltage output of the secondary. If the output is not fully loaded you may read
a higher voltage than the circuit board can handle. Do not apply power without main air supply provided.
The gauge port will accept a miniature 1/8" FNPT back-ported pressure gauge to allow direct reading of branch
line pressure. The gauge should be sealed by teflon sealing tape, and should be tightened just snug, using a
backup wrench to hold the manifold.
POSITION ADJUSTMENT OF INSTALLED GAUGES. If installation
requires adjustment of the gauge for proper reading of the face, turn the gauge no more than 1/2 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 filtered with the supplied 80-
100 micron integral-in-barb filter. Periodically check the filter for contamination and flow 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 fittings,
and use care when removing tubing to avoid damaging fittings or moving manifold.
The bleed orifice can be unscrewed with a 1/4" hex nut driver for cleaning or inspection. Do not lose the sealing
gasket or insert anything into the precision bleed orifice. Clean by swabbing with a degreaser and blowing clean
air through the orifice from the opposite direction. The color of the hex nut indicates the size of the orifice: brass
= .007"; silver = .010"; copper = .005"
This unit requires at least two cubic inches (minimum) of branch air line capacity to operate without oscillation.
Field calibration voids warranty.
CHECKOUT
Connect LonWorks network twisted pair. With power off, connect power to 24V (+) and C (-).
Supply power and the LED power indicator will light and the green LED will blink once rapidly and turn
off. This indicates the PNP is functioning properly. Any other LED action indicates a malfunction.
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 PNP can
be interrogated over the LonWorks bus for the actual output pressure.
The green LED will illuminate when the service switch is pressed to identify the node to the network,
and anytime a WINK command is received.
The PNP0.1 does not have a bleed orifice and depends on a continual pneumatic system branch bleed
of 14 to 73 scim. Use the PNP0.1 when the downstream system includes pneumatic components that
continually exhaust air. The PNP1/5/7.1 are constant bleed controllers and utilize a precision bleed
orifice to maintain a measured flow of air across the valve. For proper operation, combined exhaust
air flow (PNP orifice loss and branch system loss) must be between 14 and 73 scim.
The branch exhaust response time is determined by the combined exhaust air flow as well as pressure
differentials. If power to the PNP1/5/7.1 is lost, it will continue to bleed through the orifice until branch
pressure is zero psig.
The PNP2.1 is ideal for long branch line runs, multiple actuators, and outside air dampers because of
its 750 scim capacity.

To monitor output pressure :
NV3 - Network output SNVT_press nvo02Pressure
This variable monitors the output pressure of the PNP
Units:
kilopascals (kPa)

Leak Test alert:
NV4 - Network output boolean nvohigh_state;
NV5 - Network output boolean nvilow_state;
These variables contain the status of the leak test function of the PNP.
If nvohigh_state contains a 1 value than there is a
potential leak up failure.
If nvolow_state contains a 1 value than there is a
potential leak down failure.
