SAFETY FUNCTIONS OF VLASE™
USER MANUAL
95
COMPONENT CHARACTERISTICS
DOOR SWITCH: SAFETY SWITCH, designed in compliance with the standard currently in
effect IEC60947, EN292, EN60204, EN1088. Two redundant contacts. IP67.
B10d=2000000.
SAFETY LOGIC: main component SAFETY PLC min. PLd according EN13849-1. Output
type relays, min 10mA. To be installed in an IP54 enclosure.
CONCLUSIONS
Because MTTFd is greater than 100 years, Category is 3, max achievable DC is 99%, so
this example satisfies the PLr=c.
SAFETY FUNCTIONS OF VLASE™
Vlase™ provides inputs,outputs and actuators to implement the following safety func-
tions:
• SF.1 ENABLE (e.g. no IR laser output if "EXT_ENABLE_A" or "EXT_ENABLE_B" are
disabled, where "disabled" means contacts open)
• SF.2 INTERLOCK (e.g. no IR laser output if "INTERLOCK_A" or "INTERLOCK_B" are
disabled, where "disabled" means contacts open)
These functions have been evaluated according to UNI EN ISO 13849-1. The results are:
• SF.1:
1. - Category: B
2. - MTTFd <10 years
3. - DC: none
• SF.2:
1. - Category: 3
2. - MTTFd = 4496 years
3. - DC: feedback is provided. The determination of the diagnostic coverage (DC%) is
assigned to the system integrator depending on the supervision system in place.
4. - Response time: 10ms
