English Assembly 4 Assembly 4.1 Solid shaft version The measuring system is connected to the drive shaft via an elastic coupling. The coupling absorbs any deviations in the axial and radial direction between the measuring system and drive shaft. This prevents excessive load on the bearing. The centering collar with selective fit is used for centering in relation to the shaft. The device is fixed to the machine using three screws in the flange.

English Assembly 4.2 Hollow shaft version 4.2.1 Requirements As the installation is application-dependent, the following instructions do not claim to be exhaustive. The measuring system should be installed on a greaseless shaft. The clamping ring fixing should prevent axial slippage of the measuring system on the drive shaft, see Figure 3. Additional measures may be required to prevent axial slippage of the measuring system. The clamping of the measuring system must not have an axial load.

English Assembly 4.2.2 Dowel pin Simultaneous rotation of the measuring system, caused by the resulting torque, is prevented by a dowel pin on the machine side. The measuring system has a 6 mm deep 4K7 groove insertion on the back to hold the dowel pin. The dowel pin must reach at least 4 mm into the groove insertion. Fig. 6: Using a dowel pin to prevent simultaneous rotation When inserting the measuring system, position it so that the dowel pin is seated correctly in the groove insertion.

English Installation / Preparation for commissioning 5 Installation / Preparation for commissioning 5.1 EMC requirements CAUTION! Invalid measurement values conducted interference! due to radiated and • Radiated interference from hand-held radios, lightning strikes on the network, mobile phones and emissions from individual devices can cause the measuring system to malfunction. Pilz GmbH & Co.
English Installation / Preparation for commissioning • In particular, sources of conducted interference such as frequencycontrolled drives (circuit feedback) have a negative effect on the function of the measuring system. The 24 V power supplies must comply with SELV/PELV. The shielding effect of cables must also be guaranteed after installation (bending radius!) and after changing connectors. If in doubt, use a more flexible cable with a higher current carrying capacity.
English Installation / Preparation for commissioning 5.2 SSI communication mode SSI mode is a synchronous serial communication mode for the position of the measuring system. By using the RS422 interface for communication, sufficiently high transmission rates can be achieved. The measuring system receives a sequence of clock signals from the data receiver (control system) and responds with the current position value, which is transmitted serially and synchronously with the sent clock pulse.
English Installation / Preparation for commissioning 5.3 SSI, RS422 communication technology RS422 communication requires one cable pair for the signals Data+ and Data– and one cable pair for the signals Clock+ and Clock–. The serial data is transmitted without reference to earth as a voltage difference between two corresponding cables. The receiver simply evaluates the difference between two cables, so that commonmode interference on the transmission line does not corrupt the usable signal.
