EN 9153 Digital Position Indicators Plastic, Electronic, 6 Digits LCD Display, with Data Transmission via Radio Frequency

The particular advantage of the electronic position indicator with wireless data transmission is their programmability as well as the ability to wirelessly transmit data bidirectionally between the position indicator and the machine control unit.

The following settings can be configured using the 4 function buttons:

• Selecting incremental or absolute measurement mode
• Changing the unit of dimension (mm, inch or degree)
• Resetting the counter or setting an offset value
• Changing the display value after one turn
• Changing the resolution, i.e. the number of displayed decimal places
• Changing the direction of rotation or counting
• Changing the display orientation (based on the installation orientation)
• Setting the maximum speed of rotation

The installed lithium battery has a life of over 2,5 years. Time to replace the battery is indicated by a symbol on the display. Battery replacement is easy - simply remove the front cover.
Other important information and instructions can be found in the operating instruction for position indicators EN 9153 / EN 9154. This is included with every position indicator and can be downloaded from in the “Service” section.

Regarding the mounting options and external architecture, electronic position indicators EN 9153 with data transmission via radio frequency are very similar to mechanical position indicators EN 953 / EN 953.2 and can normally be substituted for the latter. See also „Further Information for Position Indicators“.

When mounting the position indicator, an appropriately situated mounting hole is required for the torque support.

If the position indicator is used with smaller shaft diameters, the hollow shaft diameter Ø 20 H7 can be reduced with adapter bushings EN 952.1.

Clamping plates GN 9054.6 can be used to clamp spindles after adjustment to secure them against independent or accidental turning.

If reduction is desired in addition to installation of a control knob, control knobs GN 957 are available, which combine both functions in a single element.

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 functioning 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.

The information in the operating instructions must be observed during installation, initial operation, and use. These are enclosed with the product or are provided digitally on the product page.
