USER MANUAL OL5040 IFM

Functions 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 unit (see page 14 or type label).

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

receiver transmitter LEDs red, yellow, green push button green LED yellow LED

Fix the receiver (type OLE-...) in position.

Align the transmitter (type OLS-...) towards the receiver and tighten in the same way. Maximum range is only possible with precise alignment.

Setting the switching threshold (dynamic operation)

- Moving objects in the detection area

The unit detects input signals of various intensity in any sequence and calculates the optimum switching threshold.

1

Press until the red LED flashes

Yellow and green LED's flash alternately (= unit is in the programming mode).

2

Allow the objects to pass through the detection area.Press once.

The yellow and green LED’s go out for approx. 1 s, then flash again alternately.

3	Press once.		The yellow and green LED’s go out for approx. 1s,
			then the green LED is on (= unit is in operating mode).

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

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

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).

Setting the switching threshold (stationary operation)

- Stationary objects

The unit detects input signals of various intensity in any sequence and calculates the optimum switching threshold.

1

Press until the red LED flashes.

Yellow and green LED's flash alternately (= unit is in the programming mode).

2

Place the object into the detection area *Press once.

The yellow and green LED's go out for approx. 1 s, then flash again alternately.

3	Remove the object *Press once.		The yellow and green LED's go out for approx. 1s,
			then the green LED is on (= unit is in operating mode).

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

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

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

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).

Programming the output function

1

Press for 10s.

The red LED starts to flash fast after 2 s.Then the yellow and green LED's flash alternately. After 8 s all LED's 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 diffuse reflection sensor. Display by LED's.

LED green unit is ready for operation
LED yellow output is switched
LED red	error in object detection,e.g. maladjustment, soiling of the lenses
LED's yellow + red	flashing alternately, 2Hz: output short-circuitedflashing alternately, 1Hz: internal malfunction(output is not switched)

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.
