Installation options

The Model 3700 can be wired to the sensor in either of the following configurations:

4-wire remote transmitter (requires a 4-wire cable; see Figure 5 and Wiring instructions for 4-wire remote installations)

Remote core processor with remote transmitter (requires both a

4-wire and a 9-wire cable; see Figure 6 and Wiring instructions for remote core processor with remote transmitter)

Wiring instructions for 4-wire remote installations

1.Prepare the cable as described in the sensor documentation.

2.Connect the cable to the core processor as described in the sensor documentation.

3.To connect the cable to the transmitter:

a.Identify the wires in the 4-wire cable. The 4-wire cable supplied by Micro Motion consists of one pair of 18 AWG (0,75 mm2) wires (red and black), which should be used for the VDC connection, and one pair of 22 AWG (0,35 mm2) wire (green and white), which should be used for the RS-485 connection.

b.Connect the four wires from the core processor to the appropriate terminals on the transmitter. See Table 3 and Figure 13 (standard core processor) or Figure 14 (enhanced core processor). No bare wires should remain exposed. Do not ground the shield or drain wire(s) at the transmitter.
