4.3 Sensor Connection
4.3.1 Arc Light Point Sensor EAFR-01 Connection
1.
Open the sensor side-covers, then detach the plug-
gable connectors from the sensor PCB, and prepare the
twisted shielded pair cable connecting (see Figure 10).
Figure 10. EAFR-01 Sensor Connection.
2.
Before connecting the cable to the connector, make
sure that the connecting order is correct (+, signal, and
shield). The appropriate pin information is shown on
the blue bottom part of the sensor. Plug the wires into
the connectors and fasten them by using a screw driver
(see Figure 11).
Figure 11. Location of the PIN Information and Securing
the Cable.
3.
Connect the other end of the cable to a sensor channel
on the EAFR-101 or EAFR-110P relay (see Figure 12).
