Technical line drawing of two mechanical components with threaded ends and flanges (no text or symbols)Function and features
The through-beam sensor detects objects and materials without contact and indicates their presence by a switched signal.
Range (r): see type label.
Electrical connection
Isolate power, then connect the unit (see page 17 or type label).
Core colours: BN = brown, BU = blue.
Output function light-on ( _- ) or dark-on mode ( _L ) depending on the unit (see type label).
Note: insert a miniature fuse according to the technical data sheet.
Recommendation: check the unit for reliable function after a short circuit.
Installation

receiver push button LED red transmitter LED greenFix the receiver (type OGE-...) in position.
Align the transmitter (type OGS-...) towards the receiver and tighten in the same way.
Maximum range is only possible with precise alignment.
NB: Commissioning
The through-beam sensor is supplied ready to operate (plug and play) set at the max. sensing range. This is sufficient if the through-beam 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 LED flashes. |
| The LED starts to flash rapidly. The unit is in the programming mode as soon as the LED flashes slowly |
| 2 | Set the sensitivitywithobject. Press once. |
| The LED goes out during the first measuring process. As soon as the LED flashes slowly, the unit is in the programming mode again. |
| 3 | Set the sensitivitywithoutobject. Press once. |
| The LED goes out during the second measuring process.If the programming was successful, the unit is now in the normal 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 LED flashes after step 3 for approx. 2s. The unit then passes 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 LED starts to flash rapidly. The unit is in the programming mode as soon as the LED flashes slowly. |
| 2 | During the measurement (approx. 1s) allow at least two objects to move through the sensing area of the lens. |
| The LED goes out during the first measuring process. As soon as the LED flashes slowly, the unit is in the programming mode again. |
| 3 | During the measurement (approx. 1s) allow at least two objects to move through the sensing area of the lens. |
| The LED goes out during the second measuring process.If the programming was successful, the unit is now in the normal operating mode. |
If the setting of the sensitivity is not possible (e.g. object signal and background signal are about the same), the 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.
The output of the unit is switched during the whole programming operation!
Setting of the maximum sensitivity
- Go into the programming mode (step 1).
- Interrupt the light beam.
- Press the setting button twice (see steps 2 and 3).
Locking / Unlocking
 Press for 10s. |  | The red LED starts to flash rapidly after 2s.After that the LED flashes slowly for approx. 8s. When the LED goes out the unit is locked. |
 Press for 10s. |  | After 10s the LED goes out, locking is cancelled. |
Operation
Check the safe functioning of the diffuse reflection sensor. Display by LED and by the output.
Units with light-on mode (normally closed)
The receiver receives the transmitter light LED is on, output switched: no object detected (certain range).
The receiver receives the transmitter light → LED flashes (1 Hz), output switched,: no object detected (uncertain range).
The receiver receives no transmitter light LED off, output not switched: object detected.
Units with dark-on mode (normally open)
The receiver receives no transmitter light LED is on, output switched: object pre-sent (certain range).
The receiver receives very little transmitter light → LED flashes (1 Hz), output switched: object present (uncertain range).
The receiver receives the transmitter light LED off, output not switched: no object detected.
Maintenance
Keep the lens of the sensor free from soiling. For cleaning do not use any solvents or cleaning agents which could damage the plastic lenses.
