2. Sensor Connection
2.1 Arc Light Point Sensor EAFR-01 Connection
1.
Open the sensor side covers and then detach the
pluggable connectors from the sensor PCB. Prepare
the three twisted shielded pair cable connection (see
Figure 7).
N
otee:
There is no "In" or "Out" end of the cable. Either
end of the cable can be used.
Figure 7. Sensor Side Covers Removed and Pluggable
Connectors Detached.
2.
Before connecting the cable to the connector, make
sure that the connecting order is correct (+, signal,
shield). The appropriate pin information is shown on
the bottom shell of the sensor. Plug the wires into the
connector and fasten them by using a screw driver (see
Figure 8).
Figure 8. Location of the PIN Information and Securing
the Cable.
3.
Connect the other end of the cable to a sensor channel
on EAFR-101 or EAFR-110P relay (see Figure 9).
