WIRING TYPE AV POSITIONER

2. Connect the output ports 01 and 02 as required to provide the
desired direction of rotation. Figure
examples and Figure 3-9
NOTE: The tubing arrangements shown in Figures 3-8 and 3-9
are general examples and may not reflect exactly the arrange-
ment required for the application.

1. Connect the signal wiring using ½-inch NPT conduit. Figure
3-7 shows the location of the conduit connection. See Figure
which shows the wiring diagram. This diagram is also shown on
the inside of the front cover of the positioner.
a. Type AV33 positioner - Connect the 4 to 20 mA position
demand signal wires to terminals TB1-4 (+) and TB1-5 (-) of the
terminal block (Fig. 3-10).
If equipped with optional 4 to 20-milliamp position transmitter, ter-
minals TB1-1 (+) and TB1-2 (-) provide customer access to the 4
to 20-milliamp feedback signal. If equipped with optional potentio-
metric position transmitter, three leads are available for customer
use at terminals TB1-1, TB1-2 and TB1-3. Refer to
for detailed information about position transmitters.
b. Type AV44 positioner - Connect DDC pulse or contact clo-
sure (raise/lower) input signal wires to terminals TB1-4 and
TB1-5. Connect the (+) 24 VDC to terminal TB1-3 and the posi-
tion transmitter feedback connection to terminals TB1-1 (+) and
TB1-2 (-) (Fig. 3-10).
NOTE: Route the wiring inside the positioner so it does not
become entangled with moving parts. A cable clamp (Fig.
4-1) is provided inside the positioner so entanglement can be
avoided.
2. If using a twisted shielded pair for signal wiring, ground one
end of the shielded pair at the source. Trim the other end of the
pair, located inside the enclosure, so that bare wires are not
exposed.
3. Grounding positioners should be done in accordance with
local electrical codes (in U.S, National Electrical Code, ANSI/
NFPA 70. In Canada, Canadian Electrical Code, CSA c22.1). A
3-8 shows single-acting tubing
shows a double-acting tubing example.
