Frequently Asked Questions - OW0002 IFM

What is the switching temperature of the OW0002 detector?

The switching temperature is 500 °C or 900 °C depending on device type.

Where should the amplifier and optical fiber be mounted?

The amplifier must be mounted outside the hot zone (max ambient temperature 60 °C). The optical fiber can be installed in the hot zone up to 250 °C.

How to calculate the detection diameter?

Use the formula: d = 2 × I × tan(α/2) + ∅, where I = detection distance, α = opening angle, ∅ = lens diameter.

What opening angles are available?

The possible opening angles are 68°, 7° and 2° depending on the detector model.

How to electrically connect the detector?

De-energize the installation. Connect according to DC PNP or NPN diagram. Use colors: BN = brown (L+), BU = blue (L-), BK = black (output), GN/YE = ground.

Is the detector protected against short circuits?

No, the output is not protected. A short circuit can destroy the device immediately. It is recommended to add a miniature fuse.

How to replace the optical fiber?

Remove the nut and washer, take out the rubber gasket, pull out the defective fiber. Slide the elements onto the new fiber, push it into the amplifier, replace the gasket and tighten the nut.

What to do in case of malfunction due to background?

Use devices with a higher switching temperature to avoid interference from background radiation.

What accessories are available for this detector?

A mounting base (ref. E20426), an additional lens to increase range, and spare optical fibers.

Betrieb

Function and features

Infrared heat sensors absorb the heat radiation of objects and convert it into a switching signal.

They are used for object detection or temperature monitoring.

Switching temperature 500^ C/ 900^ C (depending on the type of unit).

Installation

Mount the switching amplifier outside the hot area (ambient temperature max. 60°C). A special mounting base is available as accessory (order no. E20426) for simple mounting. Mount the fibre optics in the hot area (max. 250°C) in the required sensing distance. Use a lens attachment to extend the distance and to set the switch point more accurately (available as accessory).

The object must at least have the switching temperature of the sensor and must cover the visible area which depends on the chosen angle of aperture and sensing distance.

Notice! Do not bend the fibre optics sharply.

Calculation of diameter of visible area/sensing distance/angle of aperture

$$ d = 2 \times I \times \tan \frac {\alpha}{2} + \varnothing $$

$$ I = 0. 5 \times \frac {d - \varnothing}{\tan \frac {\alpha}{2}} $$

$$ \alpha = 2 \times \tan^ {- 1} \left(\frac {d - \emptyset}{2 \times I}\right) $$

α = angle of aperture

l = sensing distance

d = diameter of visible area

∅ = lens diameter

Sensing range diagram:

In the event of ranges of >5m radiation losses must be taken into account. The temperature of the object should therefore be much higher than the switching temperature of the sensor.

Note: insert a miniature fuse according to the technical data sheet, if specified. Recommendation: check the unit for reliable function after a short circuit Core colours of ifm sockets: BN = brown, BU = blue, BK = black, GN/YE = green/yellow.

*Output not short-circuit protected.

Short circuit can lead to immediate destruction of the unit.

Replacement of fibre optics

Remove the nut 1 and washer 2.

Carefully remove the rubber packing 3 from the connection piece.

Remove the faulty fibre optics 4.

Slide the supplied new nut 1, washer 2, packing 3 onto the replacement fibre optics.

Insert the replacement fibre optics until the end into the hole of the switching amplifier provided for this.

Press the packing 3 into the connection piece.

Secure the replacement fibre optics by tightening the nut 1.

Operation

Check the safe functioning of the sensor.

If in the application wrong switching occurs due to background radiation (e.g. ovens), use units with higher switching temperatures.
