Page 409 | 1.4 Adjusting, Positioning, Locking with and without Position Indication The position indicators and control communicate using a proprietary ELESA protocol. The control unit can only process the target and current position value of the position indicators and send these to the machine control. The machine control therefore cannot be accessed directly over the wireless network of the control unit. The radio communication is therefore protected against system alterations or third-party access. Disruptions or interference from other typical wireless networks, such as WiFi, Bluetooth, etc. do not impair the functio- ning of the system, but they may lengthen the response time of the position indicators to the control unit. Avoid placing the control unit immediately next to high-powered components, such as motors, converters, etc. If this is not possible, a safe distance of at least 200 mm should be ensured. Security information Montagehinweise Before installation the position indicator, a locating hole must be made on the machine side for the torque limiting contact point, according to the drawing (see left). With the mounting adaptor bushings GN 952.1 (→ Page 412) , the hollow shaft (with bore 14 H7 ) of the positi- on indicator can be adapted to fit the spindle. If a reduction in the diameter of the hollow shaft is to be made at the same time as mounting a control knob, control knobs GN 957 (→ Page 413) are available which combine both functions in a single component. The position indicator is mounted with the torque limiting contact point inserted in the bore hole, to stabilize the housing in place. The hollow shaft is mounted to the spindle and secured with the grub screw. With clamping plates GN 953.6 ( → Page 414) , spindles can be clamped and secured after adjusting. Installation instructions Regarding the mounting options and external architecture, electronic position indicators GN 9153 with data transmission via radio frequency are very similar to mechanical position indicators GN 953 ( → Page 396 ) and can normally be substi- tuted for the latter (see also „Explanations about position indicators“ → Page 394 ).
