Disconnect all power to the units BEFORE you begin.
NOTE: Refer to Figures 5 and 6.
1.
Use the 16 foot (5 meter) cables that are shipped with the sensors to connect the AWL 280 Sensors to the AS10-D
Amplifier. The quick disconnect plugs on the AWL Sensor's Projector and Detector have different connectors. The terminal
end of the Projector cable has a six pin connector. The Detector cable has a five pin connector.
NOTE: To avoid overlapping or mixing up the left and right cables, Nexen recommends that you connect one
side (left or right) at a time.
2.
Connect your 50/60 Hz / Single Phase 100, 110 or 120 volt power source to terminals "L" and "N". A power source that is
50/60 Hz / Single Phase with either 200, 220 or 240 volt will have "L1" and "L2" lines which will connect to terminals "L" and
"N". Find the voltage select jumper that is located on the power supply printed circuit board and set the voltage select
jumper to match the voltage of your power source. Connect a low resistance earth ground to terminal "G"
3.
Connect the AS10-D amplifier terminals "10", "11", "23" and "24" (See Fig. 6) to the GC300 Web Guide Controller (refer to
the GC300 Web Guide Controller manual, # 20331).
4.
The alarm relay changes state when the sensor lens becomes dirty and needs to be cleaned. Wire the alarm relay terminal
"25" for Normally Open (N.O.) and terminal "13" for Normally Closed (N.C.). The contacts are rated at 2 amp at 240 VAC or
2 amp at 24 VDC. Refer to the
Calibration section to calibrate the sensitivity level of the alarm relay.

CAUTION
Verify that the voltage select
jumper on the power supply is set
to match the voltage supplied to
Terminals "L" and "N".
DANGER
Dissconect all power to the units
BEFORE
you begin.
