OB5032 - Amplifier IFM - Free user manual and instructions

USER MANUAL OB5032 IFM

• Only for the connection of the ifm fibre optics type FE-11 and FT-11.

• Sensing range depends on the fibre optic. Controls and indicators out

auto range red LED: - indicates the setting mode - lights in the uncertain reception zone (maladjustment, soiling of the lens) - flashes quickly: output short-circuited - flashes slowly: internal malfunction yellow LED: switching status, lights when the output is switched green LED: lights when ready for operation push button: starts the manual setting of the switching threshold locking / unlockingMounting 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

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).

• Programming of the output function by wiring (see the last page or the type label).

ENGLISHSetting 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. 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 threshold being unchanged.

Allow the objects to pass trough the detection area. Press until the red LED flashes. Press once. Press once. Yellow and green LEDs flash alternately (= unit is in the programming mode). Yellow and green LEDs go out for a short time, then flash again alternately. Yellow and green LEDs go out for a short time, then the green LED is on (= unit is in the operating mode).Setting of the switching threshold (2)

• 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.

• 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 threshold being unchanged. Setting of the maximum sensitivity

• Go into the programming mode (step 1).

• Align the unit so that no light is reflected.

• Press the setting button twice (see steps 2 and 3).

Place the object into the detection area.* Press until the red LED flashes. Press once. Press once. Yellow and green LEDs flash alternately (= unit is in the programming mode). Yellow and green LEDs go out for a short time, then flash again alternately. Yellow and green LEDs go out for a short time, then the green LED is on (= unit is in the operating mode). Remove the object.*Locking / Unlocking Operation Only open the cover to make adjustments. Close it after the adjust- ment has been made in order to maintain the protection IP65. Check whether the unit functions properly. Function check output

• Switches in the case of incorrect object detection (error in object detection, maladjustment, soiling of the lenses) after approx. 4 s, it switches back approx. 4 s after the object is again correctly detect- ed.

• Immediately switches in the case of a short circuit of the switching output, it switches back approx. 2 s after the fault has been recti- fied.

• Immediately switches in the case of an internal fault, it is only switched back by turning off the operating voltage and then on again.

Press for 10s. The red LED lights for a short time, then the yellow and green LEDs flash alternately; after 10s the LEDs go out, the unit is locked. out

Press for 10s. After 10s the LEDs go out, locking is cancelled. out
