Frequently Asked Questions - OB5014 IFM

How to mount the OB5014 amplifier?

Mount the device on a standard profile (DIN rail) or using a mounting device. Fix it securely.

How to connect the fiber optics?

Unscrew screw A, slide the fibers into the openings until a slight resistance is felt (O-ring), push them fully against the optical elements and tighten screw A.

What is the electrical wiring?

Observe the colors: brown (BN) = +24 V, blue (BU) = 0 V, black (BK) = switching output, violet (VT) = diagnostic output. Disconnect the installation from power before connection.

How to perform automatic switching threshold adjustment with moving objects?

Pass the objects through the beam, press T1 until the LED bar flashes. Press once, then a second time. The yellow and green LEDs flash alternately. After the third press, the green LED lights up in operating mode.

How to automatically adjust the threshold with stationary objects?

Press T1 until flashing, place the object in the beam and press once, then remove the object and press again. The green LED lights up after the sequence.

How to manually adjust the switching threshold?

For direct reflection fiber: press T1+T2 until flashing, measure the object and then the background, use + or - to position the threshold in the middle, then press T1+T2 to confirm.

How to adjust the pulse extension?

Press T2 until the yellow and green LEDs flash, use + or - to adjust the delay (each press = 1 ms). The value displayed on the LED bar corresponds to ranges (2-10 ms, etc.). Wait 10 s to confirm.

What does the red LED illuminated mean?

The red LED indicates a detection error: incorrect setting or dirty fibers. Clean the fibers or adjust the threshold.

How to clean the amplifier?

Clean the fiber optics with a soft cloth if dirty. Make sure to close the cover after adjustments to maintain IP65 protection.

USER MANUAL OB5014 IFM

The switching amplifier senses objects and materials without contact and indicates their presence by a switching signal.

• Only for the connection of the ifm fibre optics type FE-11 and FT-11.
• Sensing range depends on the fibre optic.
• Pulse stretching 0 or adjustable between 2 and 90ms.

(Each input pulse is stretched to the set value).

Controls and indicators

green LEDs:

• in operating mode: excess gain in %
• in programming mode: strength of input signal red LED:

lights in the uncertain reception zone

(maladjustment, soiling of the lens)

T2: starts the setting of the pulse stretching

yellow LED:

switching status, lights when the output is switched

green LED:

lights when ready for operation

T1: starts the automatic setting of the switching threshold

T1 + T2: starts the manual setting of the switching threshold

Mounting

Mount the unit on a DIN rail or by means of a mounting fixture.

Mount the fibre optics:

1. Loosen the screw A, fig. 1.
2. Place the fibre optics into the sensor holes B until you feel a slight resistance (O ring), fig. 2.
3. Push the fibre optics until they come to a stop (optical elements) and hold them, fig. 3.
   4.Tighten the screw A.

If the fibre optics are not in contact with the optical elements, the sensing range is reduced.

Electrical connection

Isolate the power, then connect the unit as specified (see the last page or the type label).

• Core colours (for sensors with cable connection): BN = brown, BU = blue, BK = black, VT = violet.
• Programming of the output function by wiring (see the last page on the type label).
• Load of the function check output (fc-output): max. 10mA.

Automatic setting of the switching threshold (1)

• Objects move through the detection area
• Diffuse reflection fibre (FT ...) and through-beam fibre (FE ...)

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

1

Allow the objects to pass trough the detection area. Press until the row of LEDs flashes.

Yellow and green LEDs flash alternately (= unit is in the programming mode).

2

Press once.

Yellow and green LEDs go out for a short time, then flash again alternately.

3

Press once.

Yellow and green LEDs go out for a short time, then the green LED is on (= unit is in the operating mode).

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

Automatic setting of the switching threshold (2)

• Stationary objects
• Diffuse reflection fibre (FT ...) and through-beam fibre (FE ...)

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

1

Press until the row of LEDs flashes.

Yellow and green LEDs flash alternately (= unit is in the programming mode).

2

Place the object into the detection area.* Press once.

Yellow and green LEDs go out for a short time, then flash again alternately.

3	Remove the object.* Press once.		Yellow and green LEDs go out for a short time, then the green LED is on (= unit is in the operating mode).
			out on then the green LED is on (= 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 switching threshold is not possible (e.g. object signal and background signal are about the same), the row of LEDs flashes after step 3. The unit then passes into the operating mode with the switching threshold being unchanged.

Operation

Only open the cover to make adjustments. Close it after the adjustment has been made in order to maintain the protection IP65.

Check whether the unit functions properly. Indication by LEDs and by the function check output:

• Red LED lights: wrong sensing of the object (maladjustment, soiling of the lens).
• Row of LEDs flashes quickly: output short-circuited / slowly: internal malfunction.

The function check output switches in the case of

• wrong sensing of the object (maladjustment, soiling of the lens), reset after the object has been sensed again properly;
• a short circuit of the switching output, reset about 4s after the fault has been eliminated.
