3. If equipped with optional potentiometric position transmitter
(AV2___1__), connect a power supply (maximum 35 VDC or 30 VAC)
across TB1-1 and TB1-3. Use the signal across TB1-1 and TB1-2 or
TB1-2 and TB1-3 for position transmitter feedback. Refer to
Appendix A for detailed information about position transmitters.
NOTE: Route the wiring inside the positioner so it does not become
entangled with moving parts. A cable clamp (Figure B-12) is pro-
vided inside the positioner so entanglement can be avoided.
