Scope of delivery - Transmitter for angular position KINAX 3W2, acc. made to order - 3 clamps - 1 Operating instructions in German, French and English - 1 Type examination certifi cate, only with ATEX-approval 3. Application The KINAX 3W2 transmitter converts the angular position of a shaft into a load independent direct current signal, proportional to the angular position. Due to the compact design, the angular position transmitters are particularly suitable for installation in or mounting / on devices and apparatuses. Explosion-proof “Intrinsically safe Ex ia IIC T6 Gb” versions with I.S. meas uring output rounds off this series of transmitters. 4. Main features • Compact angular position transmitters for installation or mounting • Capacitive scanning system • 0/4...20mA analog output signal with 2-, 3- or 4-wire connection • Drive shaft without stops, rotating • Low starting troque • Non-wearing and low-maintenance • With explosion prevention „Ex ia IIC T6 Gb“ according to ATEX and IECEx available • With GL (Germanic Lloyd) available 5.

be mounted either directly or by means of 3 mounting clips to the item being measured. The screws are not supplied, because the required length varies ac- cording to the thickness of the mounting surface. Both methods of mounting and the relevant drilling and cut-out plans can be seen from Table.

Technical data” are not exceeded. Make the cut-out and drill the holes in the item onto which the transmitter is to be mounted according to the corresponding drilling and cut-out diagram given in Table 1 and then fi t the transmitter. Pay attention when aligning and tightening the transmitter that the transmitter zero and the zero of the item being measured coincide. Alignment is achieved by rotating the transmitter. To facilitate alignment in the case of “direct” mounting, it is recom- mended to elongate the 3 mounting holes (diam. 3.2 mm). When using mounting clips, the clips permit the transmitter to be rotated to the correct position. The electrical zero of angular transmitters with measuring ranges 0 to … ° is marked on both the front and the back (see upper illustration). It is only marked on the front, however, in the case of angular transmitters with ranges having a V characteristic and at instruments with both senses of rotation, see lower illustration.

Setting the beginning and end of the measuring range The coarse adjustment of the beginning of the measuring range consists in aligning the zero of the measured device with the external zero mark on the transmitter. The procedure was described in Section “6. Mounting”. This Section concerns the fi ne adjustment not only of the beginning of the range (ZERO), but also of the end of the scale (SPAN). Firstly, switch on the power supply to the transmitter. Remove the ZERO/SPAN sealing plug (4) (Fig. 12, left). Place the measured device at its zero position, i.e. the position at which the KINAX 3W2 should produce 0 mA (3- or 4-wire connection) resp. 4 mA (2-wire connection) at its output. Should the output current differ by more than 2 % from its initial value, repeat the coarse zero setting procedure described in Section “6. Mounting”. Then adjust the “ZERO” potentiometer (Fig. 12, right) using a watchmaker’s screw- driver (2.3 mm diam.) so that the desired output current fl ows. (4) Fig. 12 Adjustments «ZERO», «SPAN» and «S1». Left: Adjustments covered by the sealing plug (4) Right: Adjustments exposed. Now rotate the measured device to its opposite limite position, i.e. the position at which the KINAX 3W2 should produce the prescribed full-scale output current (see rating plate). Adjust the “SPAN” potentiometer with the screwdriver as before until precisely the prescribed full-scale output current is measured at the output. Now recheck the zero value and readjust on the ZERO potentiometer and then recheck the full-scale value. 9. Adaptation from 2-wire connection to 3- or 4-wire connection and vice versa Transmitters with the ordering code 708 – ...D (see Section “13. Specifi cation and ordering information”, number 4) are designed for either a 2-wire connection with an output range of 4…20 mA or a 3- or 4-wire connection with an output range of 0…20 mA. If, however, a transmitter be changed from one to the other (see wiring diagrams in Fig. 7, 8, 9 and 11), the beginning and end of the measuring range must be readjusted. 10. Reversing the rotation for instruments with measuring ranges > 150° A switch is provided on angular transmitters with a measuring range > 150° for reversing the direction of rotation. It is marked S1 and can be operated through the opening in the rear part of the transmitter (Fig. 12). To reverse the direction of rotation, remove the sealing plug (4) covering the switch S1. Then operate the switch by turning it a quarter of a turn with a watchmakers screwdriver (2.3 mm Ø), and reset the beginning and end of the measuring range. 11. Electric commissioning • Provide a separate power supply for the device in case of consumer loads with high interference levels. • Install the entire plant in an EMC-compatible manner. Installation environment and wiring can affect the EMC of the device. • For Versions with explosion protection: The regulations according to EN 60079-14, the equip- ment safety law, the generally acknowledged rules of the industry and these operating instructions are applicable for installation and operation. 12. Maintenance The device is free of maintenance. Repairs may only be carried out by autho- rized authorities.
