3.4 Sensor Input Connections

3.4 Sensor Input Connections

The RTD sensor (see Figure 3-5), can be wired in three different ways. They are 2-, 3-, and 4-wire configurations. The meter is factory set internally to a 3-wire setup. If you wish to change it, refer to Table 3-2.

2-Wire RTD:

Externally wire the P3 connector according to Figure 3-6. Keep in mind that you will need to jumper pins 1 and 2 on P3 together, and jumper pins 3 and 4 on P3 together. Use 24 AWG wire. The black lead goes to Pin 1 or 2 and the red lead goes to Pin 3 or 4.

3-Wire RTD:

Externally wire the P3 connector according to Figure 3-7. Pin 4 on the P3 connector is not used.

4-Wire RTD:

Externally wire the P3 connector according to Figure 3-8.
