Access control for enhanced safety

Posted on Friday 1 January 2010

Wieland Electric’s SLC series of safety light curtains has been designed to protect operators from dangerous areas or as access control against unauthorised trespassing.

Connection is achieved via standard M12 connection technology, while fast installation and removal of the guards on the machine is achievable due to system configuration being carried out in the control cabinet.

When using multiple systems, mutual interference is avoided by using the adjustable range reduction feature, while the integrated double scan technology eliminates the risk of unnecessary shutdown even in harsh environments.

Planning of safeguards is simplified and there is less type diversity because every SLC from 0m to the maximum range can be utilised. 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. The SLC Series has an aluminium IP67 rated, rigid housing that aids adjustment and helps to ensure reliable operation, with clear diagnostic and status messages in the 7 segment display to ensure shorter downtimes.

Cable lengths up to 100m with unshielded connection cables ensure greater operational flexibility and cost reduction even under difficult EMC conditions. The SLC series also offers simplified planning of safeguards and less type diversity because very SLC safety light curtain from 0 m to the maximum range can be implemented.
