6.3 Field Wiring Schematics
The following diagrams are intended to be used as examples for connecting the
AccuValve
®
AV3000 to Field Devices. Reference the inside of transmitter cover for
identification of connectors.
NOTE: Use 16-22 AWG Shielded Cable.
6.3.1Typical wiring between the AccuValve
®
and DDC Control Panel
Wiring shown is for (2-10 VDC or 0-10 VDC) Analog Output. For using a current Analog Output (4-20mA or 0-20mA) install a
500-ohm 1/4 watt resistor across Analog and - terminals at the Controller.
1
Polarity must be maintained if transformer is used to power multiple devices otherwise equipment may be damaged. Power
source must include a circuit breaker and be current limited to 8 amps maximum and grounded on the (-) side.

3. The above wiring diagrams are intended to be used as a general guide for wiring the AV3000 to a DDC Controller. The
detailed wiring diagrams provided by the Controls Contractor shall be used in conjunction with this document.
Actuator #2 is used for 12x36" and 12x48" valves only.
