The small size, low current, voltage and impedance values that characterise them allow their use in various applications in hazardous areas with explosive atmospheres consisting of a mixture of AIR/GAS and/or AIR/DUST. The sensors of this series must always be connected to intrinsically safe circuits covered by an EC Type examination certificate, respecting the connection instructions given on page 7.

The sensitivity increases when the trier is rotated in the clockwise direction and decreases in the anticlockwise direction. Avoid using for a capacity greater than referred to a square piece of steel (FE7) of thickness the side of which is equal to 00. When setting the sensor keep in consideration all other Metallic object nearby, in fact setting is suggested to be made when the sensor is installed in the normal working conditions. The sensor is supplied already preset to 0 sensitivity.

DIMENSIONS OF THE OBJECT (Fe7) TO DETECT PLUG H H OUTPUT POSITION VIEW SENSITIVITY ADJUSTMENT In ring sensors, the sensing is carried out inside the ring. The sensor intervenes when a metallic object is introduced. They are particularly suitable for checking the presence and counting of small metal objects, screws, nuts washers etc. or for any similar operation. Also useful in verifying breakage of metal wires that pass through the ring. The ring sensor s housing is in plastic and electrical attachments can be made by means of a cable or M8 and M connectors depending on the model type. Model Length Diameter SIA0 0.7 SIA. SIA.

In this way the sensitivity adjustment can be made within normal parameters and need not be pushed to the maximum risking the proper functioning of the unit. CONNECTION TO INTRINSICALLY SAFE CIRCUITS See page 7 SENSITIVITY ADJUSTMENT After having followed the instructions regarding the choice of the most suitable unit it is recoended that the sensitivity adjustment be carried out when the sensor is installed in the final position taking into account how much metal mass is close by which could alter its functioning. The sensitivity increases turning the trier clockwise. EFFECTS OF METAL IN THE CLOSE VICINITY If a moving metal part is close to the sensing area the functioning can be disturbed. In order to avoid this, install the units some distance from metallic objects. Ensure that this does not interfere with the functioning. USE OF SENSOR A distance equal to the width of the sensor should be left between each object that passes through the sensor. If more than one sensor is to be installed in close vicinity, the minimum distance indicated between sensors should be observed.

Io Maximum current that may be taken from the ends of the intrinsically safe circuit of the associated device Po Maximum power that can be supplied by an intrinsically safe circuit of the associated device. Co Maximum capacity that can be connected to the ends of the intrinsically safe circuit of the associated device. Lo Maximum inductance that can be connected to the ends of the intrinsically safe circuit of the associated device. 7
