Safety Light Curtains with Bluetooth interface
Schmersal is introducing a BluetoothTM interface in our Safety Light Curtains, as a standard feature, now available on our SLC440COM and multifunctional SLC440 series.
These safety light curtains use the BluetoothTM Low Energy system for near-field data transmission, which provides secure data transmission up to 5 meters. The data transmitted from the safety light curtains with BluetoothTM interface is accessible by the Schmersal SLC Assist App, available for Android and iOS smartphones and tablets.
This unprecedented access to the operational data of the Safety Light Curtain has many advantages:
The app can display the signal strength of each beam when you align the light curtain, making it easier to see how your adjustments are affecting the alignment. It also has a three-star rating for the alignment: One star is shown if the quality of the alignment needs to be improved; Three stars are displayed when the alignment is perfect.
Device and configuration data
With the device data you get general information about the light curtain such as the type, the serial number, the protective field resolution and the field height. Additionally, you can see which functions have been enabled and their parameterized settings. The SLC440 offers many integrated functions including fixed blanking, floating blanking, fixed blanking with movable edge region, double reset, contactor control (EDM), automatic mode, re-start mode, and beam coding.
With the display of the device status you see the signal strength of each individual beam in real time, the active operation mode, the status of the OSSD outputs and the status of the protective field. Since the status data of the light curtain can be accessed easily and in real-time, errors can be resolved quickly to achieve increased machine availability.
Service and maintenance
The app provides information such as operational hours and the number of switching cycles the safety light curtain has performed. This data is helpful in scheduling preventive maintenance, service cycles for safety relay modules, and defining the intervals for intermediate checks.
Information on the active status of the light curtain can be saved to the smartphone or tablet. This facilitates the documentation after a functional or intermediate inspection. Additionally, this status information can be emailed from the app, to store it to your document server.
Safety light curtains SLC440 are used for the protection of hazardous areas, and are available with resolutions of 14 or 30 mm and protection field heights between 170 and 1930 mm; Also available as safety light grids (SLG440) with 2, 3, or 4 beams for perimeter guarding.
Safety light curtains SLC440COM are used for the protection of hazardous areas, and are available with resolutions of 14, 30, or 35 mm and protection field heights between 330 and 1930 mm; Also available as safety light grids (SLG440COM) with 2, 3, or 4 beams for perimeter guarding.
Both series are suited for use in safety circuits up to PLe (EN 13849) or SIL3 (IEC 61508). Both are also available with an IP69 Rated housing for washdown applications
