SAFETY FUNCTIONS OF AREX
TM
Arex
TM
provides inputs and actuators to implement the following safety functions:
- 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 has been evaluated according to UNI EN ISO 13849-1. The results are:
- SF.1:
- Category: B
- MTTFd <10 years
- DC: none according category
- SF.2:
- Category: 3
- MTTFd = 113 years (dop=365days, hop=24h, Tcycle=1800s)
- DC: because Arex
TM
doesn't provide feedbacks, a measure of fault detection must be included in
the process. The estimate for DC is 0% to 99% depending on the application. This measure alone
is not sufficient for the PL "e". If it is executed a test every 100 working hours, then DC=60%.
- Response time: 5ms
