Sensor Installation
Do not attempt to change the lens position on the sensor housing. The sensor will
work only with the lens in the bottom port (see Figure 2). No optical components
exist behind the blanking plug on the sensor front; do not remove the blanking plug.
1. Loosen the connector locking screw (several turns), and position the QD connector
as needed (back, side, or bottom of the sensor). Tighten the locking screw after the
connector is properly positioned.
2. Measure the appropriate operating distance from the front surface of the sensor
optics to the surface or object to be sensed. Do not exceed the sensing range for
your model (see page 1 for sensor model and range).
3. Fasten the sensor to its intended location using two to four M5 mounting screws
and washers. There are four mounting holes on the bottom (lens side) of the
sensor and two on each side (see page 7).
NOTE: Proper mounting screw length depends on mounting bracket thickness.
Additional washers may be necessary to make sure the screws do not
exceed the thread depth.
4. Attach the QD cable to the sensor’s connector; see hookups on page 7.
Sensor Operation
Power up the QL55 Sensor after programming, setup, and installation. The green
Ready LED turns ON to indicate that the sensor is in RUN mode and ready to sense
the luminescent target as programmed. When configured as described on page 3,
sensing the target object will cause the normally-open output to close and the red
Output LED to turn ON.
If the sensor experiences an output overload condition during operation, the green
Ready LED will flash fast (approx. 4 Hz). Verify that output current is less than
200 mA.
