VLASE™ IR
Application example
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 safety switch is connected as input of a safety logic and Vlase™ interlock
system as output/input of that safety logic.
• Warning label for access panel according EN60825-1 must be applied.
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
Severity of injury (S)
S1 Slight (normally reversible injury)
S2 Serious (normally irreversible injury or death)
Frequency and/or exposure time to hazard (F)
F1 Seldom to less often and/or exposure time is short
F2 Frequent to continuous and/or exposure time is long
Possibility of avoiding hazard or limiting harm (P)
P1 Possible under specific conditions
P2 Scarcely possible
CAUTION
This example relates only to the features introduced in Vlase™ to assist in
the risk reduction from the laser radiation. Any other risks (mechanical,
electrical, etc.) must always be evaluated and appropriate risk reduction
measures must be taken where necessary.
The Machinery Directive and EN 13849-1 are NOT applicable to the product
Vlase™.
The target safety integrity or performance level (e.g. PLd according to
ISO13849-1) shall be determined by the machine integrator, taking into
account the machinery directive, the harmonized standards and any sec-
tor-specific standard that may apply.
CAUTION
This example is based on the parameters indicated in paragraph "
