Frequently Asked Questions - OM5001 IFM

How to precisely align the transmitter and receiver?

After electrical connection, align the receiver using the red LED: Red LED on indicates precise alignment, Red LED flashing indicates imprecise alignment. Align until a steady light is obtained.

What does the flashing red LED mean?

The red LED flashes in case of deteriorated reception, for example due to dirty lenses or misalignment. If the signal remains unstable for two seconds, the output switches and remains switched until a safe signal is received.

How to adjust sensitivity to detect a transparent object?

First set sensitivity to maximum by turning the 'Range' potentiometer to the left until it clicks. Place the object between transmitter and receiver. Turn the potentiometer to the left until the yellow LED (output) just lights up. Remove the object and note the number of turns until the yellow LED lights up again. Turn back half that number of turns.

How to select light-on or dark-on mode?

Use the operating mode selector on the receiver. In light-on (NC) mode, the output switches when the object is not present. In dark-on (NO) mode, the output switches when the object is present. The yellow LED indicates the switching state.

What to do if the output does not switch?

First check the power supply (green LED on). Check alignment (red LED must be steady on). Check cleanliness of lenses and sensitivity adjustment. If the problem persists, test the transmitter test input (DC) to disable light emission.

How to use the transmitter test input?

The test input (test at L-) disables light emission. If no object is between transmitter and receiver, the receiver LEDs should turn off and the output should change state. This allows verifying proper operation of the cell.

What is the maximum range of the detector?

The maximum range is 50 meters with precise alignment and clean lenses. Any obstruction or dirt reduces the range.

Can I clean the lenses with a solvent?

No, do not use any solvent or aggressive product. Use a soft dry cloth to clean the plastic lenses.

What to do in case of dirty lenses?

Clean the lenses with a soft dry cloth. If dirt persists, you can use a little soapy water, but without solvent. After cleaning, check alignment and sensitivity.

How to verify proper operation after installation?

After mounting and connection, open the cover for adjustments, then close it to ensure IP67. Check that the green LED is on. Pass an object in front of the detector: the yellow LED should light up in dark-on mode. If the red LED flashes, realign the elements.

USER MANUAL OM5001 IFM

Through-beam sensor OM

Functions and features

The through-beam sensor detects objects and materials without contact and indicates their presence by a switched signal.

Range: 50m.

Installation

Fix the receiver (type designation OME ...) via the mounting holes in the unit housing or via the M30 x 1.5mm thread using the mounting accessories supplied. Then align the transmitter (type designation OMS ...) to the receiver and fix it in the same way.

Electrical connection

Disconnect power before connecting the sensor.

Connection strictly to the indications on the type label.

After electrical connection you can exactly align the receiver by means of the red LED.

• The red LED is lit with exact alignment;
• it is flashing with inexact alignment.

Maximum range is only achieved with precise alignment.

Sensitivity setting

Through-beam sensors are usually operated in the dark-on mode. In most applications maximum sensitivity can be used for operation. The settings described below are only necessary if partly transparent or small objects are to be detected.

• Set the sensitivity to its maximum by turning the "Range" potentiometer " of the receiver counter-clockwise until you hear a click.
• Place the object to be detected between the transmitter and the receiver.
• Turn the potentiometer for the sensitivity setting counter-clockwise until the yellow LED (output) is just lit.
• Remove the object to be detected.
• Turn the potentiometer for the sensitivity setting counter-clockwise until the yellow LED (output) is just lit and count the number of revolutions.
• Turn the potentiometer for the sensitivity setting back clockwise by half of the revolutions counted before.
• For selecting the light-on or dark-on mode, set the slide switch to the requested operating mode.

Test input of the transmitter (only for DC units)

By activating the test input (test at L-) the transmitter is deactivated. When no object is in the light beam between transmitter and receiver the LEDs indicating the reception of light must go off and the switching state of the output must change.

Operation

Only open the cover to make adjustments. Close it after the adjustment has been made in order to maintain the protection IP67.

Check whether the unit functions properly.

• Light-on mode - the output is switched when the object is not present. The yellow LED (only receiver) is lit.

• Dark-on mode – the output is switched when the object is present. The yellow LED (only receiver) is lit.

• The green LED is lit when the sensor is ready for operation.

• The red LED (only receiver) is lit when the light is received (= no object between transmitter and receiver);

• it flashes when reception is impaired (e.g. due to soiling of the lenses or maladjustment). If an unsafe signal is present for two seconds, the function check output switches and remains switched until a safe signal is received.

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.
