Installation
6 RT-SVN09E-EN
Wiring the Sensor - IntelliPak II
1. Wire the sensor from the ground terminal (terminal 0)
to 1TB6-18. 1TB6-18 is wired to J7-3 on the VCM.
2. For voltage output, wire terminal V(OUT) on the sensor
to 1TB6-17. 1TB6-17 is wired to J7-2 on the VCM.
3. Attach the mounting plate to the duct
wall with four screws.
4. Insert the sensor through the mounting
plate, adjusting the depth for optimal air
sensing.
5. If conduit is required, remove the wiring
grommet and install the supplied 1/2-inch
National Pipe Thread (NPT) conduit
fitting.
6. On the circuit board, use the two jumpers
next to the terminal block to set up the
type of output (0-10 Vdc, 0-20 mA,
4-20 mA). The default setting is 4-20 mA.
This needs to be changed to 0-10 Vdc.
