Function and features

In conjunction with a prismatic reflector or reflective tape the retro-reflective sensor detects objects and materials without contact and indicates their presence by a switched signal.

Range (r): see type label (value referred to prismatic reflector with ∅ 80mm).

Electrical connection

Isolate power, then connect the unit (see page 17 or type label).

Core colours: BN = brown, BU = blue, BK = black, WH = white.

Programming of the output function by push button (see page 11).

The units with cable gland have a removable terminal block with screw terminals (screws are at the base of the terminal block).

After connection of the wires the terminal block must be reinserted.

Note: insert a miniature fuse according to the technical data sheet, if specified.

Recommendation: check the unit for reliable function after a short circuit.

Installation

Fix prismatic reflector / reflective tape in desired position. Align the photocell photocell towards the reflector and fasten it to a mounting bracket; the light spot must hit the prismatic reflector.

Maximum range is only possible with precise alignment.

NB: Commissioning

The retro-reflective sensor is supplied ready to operate (plug and play) set at the max. sensing range. This is sufficient if the retro-reflective sensor can operate with maximum excess gain (highest contrast). The following setting procedures should only be necessary in less straightforward applications, for example if partly transparent objects must be detected.

Setting of the sensitivity with stationary objects

1	Activate the programming mode of the unit. ←→ Press for about 2s until the red LED flashes.
	The red LED goes out; the yellow and green LEDs flash alternately.The unit is in the programming mode.

2	Set the sensitivitywithobject.Press once.----
	The yellow and green LEDs go out for approx. 1s,then flash again alternately.
3	Set the sensitivitywithoutobject. Press once.
	The yellow and green LEDs go out for approx. 1s,after approx 3s the green LED is on.The unit is in the operating mode.

You can also proceed in reverse order: first setting without the object, then with the object.

If the setting of the sensitivity is not possible (e.g. object signal and background signal are about the same), the red LED flashes after step 3 for approx. 2s. The unit then passes into the operating mode with the sensitivity being unchanged.

If the setting button is not activated for 15 minutes during the programming process, the unit passes automatically into the operating mode with the sensitivity being unchanged.

Setting of the sensitivity with moving objects

1	Activate the programming mode of the unit.
	Press for about 2s until the red LED flashes.
	The red LED goes out; the yellow and green LEDs flash alternately. The unit is in the programming mode.
2	During the measurement (about 1s) allow at least two objects to move through the detection area.
	The yellow and green LEDs go out for approx. 1s, then flash again alternately.

3	During the measurement (about 1s) allow at least two objects to move through the detection area.
	The yellow and green LEDs go out for approx. 1s, after approx. 3s the green LED is on.The unit is in the operating mode.

If the setting of the sensitivity is not possible (e.g. object signal and background signal are about the same), the red LED flashes after step 3 for approx. 2s. The unit then passes into the operating mode with the sensitivity being unchanged.

If the setting button is not activated for 15 minutes during the programming process, the unit passes automatically into the operating mode with the sensitivity being unchanged.

Setting of the maximum sensitivity

• Go into the programming mode (step 1).
• Align the unit so that no light is reflected.
• Press the setting button twice (see steps 2 and 3).

Programming the output function

Press for 10s.

The red LED starts to flash fast after 2s. Then the yellow and green LEDs flash alternately. After 8s all LEDs go off, the output function has changed from light-on mode to dark-on mode (or vice versa).

Operation

Check the safe functioning of the unit. Display by LEDs and by the function check output

LED green is lit Unit is ready for operation.
LED yellow is lit Output is switched.
LED red is lit	Error in object detection, e.g. maladjustment, soiling of the lenses.
LEDs yellow + red	Flash alternately, 2 Hz: output short-circuited. Flash alternately, 1 Hz: internal malfunction (output is not switched).

Function check output

(only for sensors with DC power supply)

• Switches in the case of incorrect object detection (error in object detection, maladjustment, soiling of the lenses) after approx. 4 s, it switches back approx. 4 s after the object is again correctly detected.
• Immediately switches in the case of a short circuit of the switching output, it switches back approx. 2 s after the fault has been rectified.
• Immediately switches in the case of an internal fault, it is only switched back by turning off the operating voltage and then on again.

Maintenance

Keep the plastic lenses of the sensor free from soiling.

For cleaning do not use any solvents or cleaning agents which could damage the plastic lenses.
