Set Up:
Start by inserting the sensor wires into the Sensor Signal Input Connector. The Signal Input Terminals are
indicated in (Figure 1) below:
(Figure 1)
Insert a flat bladed micro screwdriver into the square hole above or below the round wire insertion hole as
shown in (Figure 2). This will open the metal cover over the round wire insertion hole. After you have
inserted the wire, remove the flat bladed micro screwdriver to secure the wire in its position. Once all of the
necessary wires have been attached to the Signal Input Connector, plug the connector into the 9870
indicator and secure it with the screws located on each side.
