Thru-beam sensor

OBE2000-R2-SE3

5

Recommended application:

This method enables extremely small differences in contrast to be detected, as well as minuscule particles in the beam path, and provides

exceptional positioning accuracy.

The best results are achieved in "High Precision" mode.

1. Make sure that there are no objects in the beam path and that the sensor is connected to the power supply.

2. Connect the white cable on the receiver (WH/IN) to the blue cable (BU/0 V) on the receiver.

The green and yellow LED indicators flash simultaneously at 2.5 Hz

3. Disconnect the white cable on the receiver (WH/IN) from the blue cable (BU/0 V) on the receiver.

The green and yellow LED indicators flash alternately at 2.5 Hz

4. The end of the Teach-in process is indicated when the green LED indicator lights up sold and yellow LED blinks.

Two-Point Teach-In

When using this Teach-in method, the following settings are made on the thru-beam sensor:

• The gain is set to an optimum value

• The signal threshold is set in the center between the two taught signal values

Recommended application:

Enables detection of transparent objects.

The best results are achieved in "High Precision" mode.

1. Make sure that there are no objects in the beam path and that the sensor is connected to the power supply.

2. Connect the white cable on the receiver (WH/IN) to the blue cable (BU/0 V) on the receiver.

The green and yellow LED indicators flash simultaneously at 2.5 Hz

3. Position the object in the beam path.

4. Disconnect the white cable on the receiver (WH/IN) from the blue cable (BU/0 V) on the receiver.

The green and yellow LED indicators flash alternately at 2.5 Hz

5. The end of the Teach-in process is indicated when the green LED indicator lights up sold.

Maximum Teach-In

When using this Teach-in method, the following settings are made on the thru-beam sensor:

• The gain is set to a maximum

• The signal threshold is set to a minimum

Recommended application:

Enables an object to be detected with a high excess gain. This can be useful if there is severe environmental contamination or to achieve long

operating times.

The best results are achieved in "High Precision" mode.

1. Make sure that there are no objects in the beam path and that the sensor is connected to the power supply.

2. Cover the receiver or transmitter.

3. Connect the white cable on the receiver (WH/IN) to the blue cable (BU/0 V) on the receiver.

The green and yellow LED indicators flash simultaneously at 2.5 Hz

4. Disconnect the white cable on the receiver (WH/IN) from the blue cable (BU/0 V) on the receiver.

The green and yellow LED indicators flash alternately at 2.5 Hz

5. The end of the Teach-in process is indicated when the green LED indicator lights up sold.
