Wiring Connections
Several electrical connections must be made from
the field panel, or UC to the terminal to operate the
AO–P Transducers and the differential pressure
transmitter.
NOTE: The AO–P Transducer used in these steps
is P/N 545-113.
1. Connect a two-conductor 20 AWG cable to
the field panel’s 0 to 10V output or UC’s
universal output. Connect it to the AO–P
Transducer connected to the mixing damper
or through the wiring bushing/knockout on
the terminal enclosure (Figure 5) to the AO–
P Transducer inside the enclosure. The wire
bushing can be removed and a standard
1/2-inch conduit knockout fitting may be
installed. Connect the cable to the AO–P
Transducer (See Figure 6).
2. Connect a two-conductor 20 AWG cable to the
field panel’s 4 to 20 mA input or UC’s universal
input. Connect it to the differential pressure
transmitter (Figure 7) or through the wiring
bushing/knockout on the terminal enclosure
(See Figure 5) to the differential pressure
transmitter inside the enclosure. Connect the
cable to the differential pressure transmitter.
The installation is now complete.
