Robust safety light curtains

April 2021 IS & Ex

Ez-Screen LS light curtains are intuitive, easy-to-use safety devices designed by Turck Banner for machine safeguarding. They are built to withstand challenges commonly found in manufacturing and packaging environments. A heavy-duty aluminium housing and recessed window ensure the emitter/receivers are resistant to damage in harsh environments, while the no blind-zone design provides end-to-end sensing to eliminate gaps in detection.

All LS-S models have trip output with auto power-up and automatic reset. In typical operation, if any part of an operator’s body, or any opaque object, of more than a pre-determined cross section is detected, the solid-state switching device safety outputs turn off. These outputs are connected to the guarded machine’s final switching devices that control the machine’s primary control elements, which immediately stop the motion of the guarded machines.

Quick and easy configuration

LS-S models require no PC software, DIP switches, or other devices for quick, easy configuration. Highly visible alignment indicators and intuitive diagnostics simplify setup, facilitate troubleshooting, and minimise system downtime. Units are extensively FMEA (failure mode and effects analysis) tested to establish an extremely high degree of confidence that when properly installed, no system component, even if it should ever fail, can cause a failure to danger. Because of the dual screen technology, the sensors are highly immune to EMI, RFI, ambient light, weld flash, and strobe lights. Typical applications include:

• Automated production equipment.

• Robotic work cells.

• Moulding and power presses.

• Assembly and packaging machines.

• Lean manufacturing systems.
