Frequently Asked Questions - OB5015 IFM

How to connect the fiber optics to the OB5015 amplifier?

Unscrew screw A, slide the fiber optics into openings B until you feel a slight resistance (O-ring), then push them to the stop (optical elements). Tighten screw A. Do not force to avoid reducing the range.

How to perform automatic switching threshold adjustment?

Pass the objects through the beam. Press T1 until the LED ramp flashes. Press once, then a second time. The green LED lights up to indicate operating mode. If the ramp flashes after step 3, adjustment was not possible.

How to manually adjust the switching threshold?

Press T1+T2 until the LED ramp flashes. The green LED flashes. Place the object then remove it from the beam. Use the + and - buttons to position the threshold in the middle between object and background signal. Press T1+T2 to confirm.

How to adjust the pulse extension?

Press T2 until the yellow and green LEDs flash alternately. Use + or - to set the delay (1 press = 1 ms). Wait 10 seconds to confirm. The green LED lights up in operating mode.

What do the different LEDs on the amplifier mean?

Green LEDs: in operation, indicate reserve capacity; in programming, signal intensity. Red LED: unsafe reception (poor adjustment or dirt). Yellow LED: switching state. Steady green LED: device available.

What to do if the red LED is permanently on?

This indicates unsafe reception. Check the threshold adjustment and the condition of the fiber optics (dirt). Clean or reposition the fibers if necessary. Perform a new automatic adjustment.

What is the supply voltage of the OB5015?

The device operates on direct current (DC). The wires are: BN (brown) = +, BU (blue) = -, BK (black) = output, VT (violet) = diagnostic output. The typical voltage is 10 to 30 V DC.

How to mount the amplifier on a DIN rail?

The device clips directly onto a standard profile (DIN rail). An optional mounting device can also be used. Ensure the amplifier is securely fastened.

What types of fiber optics are compatible?

Only IFM fiber optics type FE-11 (through-beam) and FT-11 (direct reflection) are compatible. Do not use other models.

Is the diagnostic output protected against short circuits?

Yes, in case of a short circuit on the switching output, the LED ramp flashes quickly and the diagnostic output is activated. It deactivates about 4 seconds after the fault is cleared.

Français

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 or 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).

* 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.

Manual setting of the switching threshold (1)

- Stationary objects / Diffuse reflection fibre (FT ...)

1	Press until the row of LEDs flashes.		Green LED flashes,yellow LED indicates theswitching status(= unit is in theprogramming mode).
2	Place the object into the detection area.		Object signal is measured and indicated (= row of dimly lit LEDs)brightly flashing LED = current switching threshold.
3	Remove the object.		Background signal is measured and indicated(= row of dimly lit LEDs).
4	Press the "+" or "-" button until the switching threshold is in the middle between the background signal and the object signal;(here: reducing the switching threshold).
5	Press until the row of LEDs flashes.		Green LED lights(= unit is in the operating mode).

Adjust of the pulse stretching

1	Press until the row of LEDs flashes.		Yellow and green LEDs flash alternately (= unit is in the programming mode).
2	Press the "+" or "-" button to set the desired delay time (here: increasing delay time).1 x = about 1ms; hold the button pressed for fast setting.
3	Wait for approx. 10s.		Green LED lights (= unit is in the operating mode).

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 qickly: 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.
