Wireless electronic digital position indicators

Efficient machine set-up

Using the UC-RF control unit, connected to the machine’s PLC via one of the available buses, it is possible to remotely configure each parameter of each connected position indicator. These parameters include: target position, pitch, display orientation, rotation direction, resolution, etc.
The current position and target position are displayed on the indicator’s LCD display.
The operator manually sets the position of the control shafts, following the indications shown on the display, such as the arrows indicating the direction of shaft rotation.
The machine’s PLC, via the UC-RF control unit, can easily verify that all drive shafts have been correctly positioned and that the set-up has been completed.

LED
Four LEDs located on the UC-RF control unit allow the operator to verify correct installation and data transmission.
Connection between Indicators and UC-RF Control Units
Each indicator is identified by a unique number assigned by Elesa. Once the connection with a control unit is established, communication will take place exclusively with that control unit, making it impossible to exchange data with other units present in the same work area. Each control unit can monitor up to 36 indicators simultaneously. In addition, the control unit checks and communicates the transmission quality to the PLC with various indicators.
Safety
The system ensures production quality by stopping the machine until the set-up is perfect, thus optimising the production process.
System protection
Radio frequency communication between the UC-RF control unit and the indicators can also take place in environments where Wi-Fi, Bluetooth, cellular networks, etc. are present. Furthermore, since the indicators and the UC-RF communicate via an Elesa proprietary protocol, it is not possible to access the PLC via the UC-RF.

Flashing display
When the indicator receives a new target position from the UC-RF, the display starts flashing, indicating that it is not in a correct position. The display shows the distance to the new target position and the direction to rotate the shaft. When the operator reaches zero, the display stops flashing to indicate that the new target position has been reached and displays the current position.
Battery check and replacement
The indicator continually sends battery status updates to the central unit, allowing for timely replacement if necessary. The indicator is able to maintain the position and the data acquired during the settings for the time necessary to change the battery.
