4.2 Sensor connection
4.2.1 Arc light point sensor EARF-01 connection
1. Open the sensor side covers and then detach the pluggable
connectors from the sensor PCB and prepare the twisted
shielded pair cable connecting (see Figure 7).
Figure 7. EAFR-01 sensor connection step 1.
2. Before connecting the cable to connector, make sure that the
connecting order is correct (+, signal, shield). The appropri-
ate pins information is shown on the blue bottom part of the
sensor. Plug the wires into connector and fasten them by using
a screw driver (see Figure 8).
Figure 8. EAFR-01 sensor connection step 2.
3. Connect the other end of the cable to a sensor channel on the
EAFR-101 or EAFR-110PLV relay (see Figure 9).
Figure 9. EAFR-01 sensor connection step 3.
4. Check the front panel of the relay. Only the POWER LED turns
on at this moment (see Figure 10).
Figure 10. EAFR-01 sensor connection step 4.
5. Attach the connector back to the sensor PCB (see Figure 11).
Figure 11. EAFR-01 sensor connection step 5.
6. After connecting the sensor to the relay, the ERROR LED turns
on, and the appropriate sensor channel LED starts to blink (e.g.
S1 LED) (see Figure 12).
Figure 12. EAFR-01 sensor connection step 6.
7. Press and hold the SET push button on the front panel for two
seconds in order to run the system auto-configuration setting
(see Figure 13). The relay memorizes the sensor amount and
binary input lines connected (if any).
