SLC Series safety light curtains from Wieland Electric have been designed to protect operators from dangerous areas or as access control against unauthorised trespassing
Wieland says that its SLC Series feature slim, rigid housings that enable easy adjustment and stable operation, with integrated double-scan technology that avoids unwanted downtime even in harsh operating conditions. The series is said to provide effective and economical optoelectronic protection which is customisable to most machine applications.
When using multiple systems, mutual interference is avoided by using an adjustable range reduction feature, whilst the integrated double scan technology eliminates the risk of unnecessary shutdown even in difficult environments. Wieland says that the planning of safeguards is simplified and that there is less type diversity because every SLC from 0 m to the maximum range can be utilised. The setting of parameters is done without PC or DIP switch and is carried out through simple wiring in the control cabinet. The 3-zone alignment indicator reduces assembly time and simplifies set up. Further, the SLC Series has an aluminium IP67 rated rigid housing that aids adjustment and helps to ensure reliable operation. It also offers clear diagnostic and status messages in the 7 segment display to ensure shorter downtimes.
Cable lengths up to 100 m with unshielded connection cables ensure useful operational flexibility and cost reduction even under difficult EMC conditions. The SLC series is also claimed to offer simplified planning of safeguards and less type diversity because every SLC safety light curtain from 0 m to the maximum range can be implemented. They can be made as Type 2 or Type 4 devices, and are available in five beam resolutions (14, 20, 30, 40, and 90mm), with protection field heights spanning 150mm–1800mm, and an extensive range of accessories. The units are highly configurable and are said to be easy to install, adjust, and remove. All SLC Series light curtains are compatible with Wieland’s safety relays and samos® PRO Series programmable safety controllers, which enable the implementation of advanced control features like muting functions.
