UNIQ™
Example automatic production line
In this case the Protective Housing may have a guard capable of being opened or
removed, typically only for service operation (frequency: seldom or occasional):
• Guard opening should only be possible with the aid of a tool.
• Guard interlock is connected as input of a safety logic (e.g. safety PLC) and UniQ™
interlock system as output/input of that PLC.
• Warning label for access panel according EN60825-1 must be applied.
DANGER
Since the frequency is LOW (F1) and the removal of the guard is intentional, the MINI-
MUM REQUIREMENT as per IEC13849-1 is PLc.
Target: PLr = c
