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. Verify that the AS10-D output voltage is compatible with the Web Guide Controller BEFORE you connect them together (refer to
the Specifications section, page 10). After you have verified compatibility, connect the AS10-D amplifier terminals "10", "11", "23"
and "24" (See Fig. 6) to the Web Guide Controller.
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".
