3.2 Emitter and Receiver Hookups
Connect the emitter and receiver cables as
shown in Figure 3-6.
Receiver Output 1: (OUT1) is an open-
collector NPN transistor switch rated at
30V dc max., 150 mA max. It is protected
against overload and short circuits.
Receiver Alarm: (ALARM) is an open-
collector NPN transistor switch rated at
30V dc max., 150 mA max. It is protected
against overload and short circuits.
Both outputs are current sinking.
3.3 Diagnostic LED Indicators
The emitter has a single Red status LED.
The receiver’s three LEDs (Green, Yellow,
and Red) are used in combination to
diagnose system status.

3.4 Optical Alignment
After connecting the cables per Figure 3-5, apply 16-30V dc power to the sensor.
Rotate the emitter and/or receiver as necessary to align them. When aligned, the
receiver Green LED is ON. Align the emitter and receiver until the receiver’s Green
LED is ON and the Yellow and Red LED are OFF.
Installation and Alignment
* If after cleaning the emitter and receiver lenses, the emitter diagnostic is solid Red, consider replacing the receiver.
