STA 1oo2 Voting with High Availability

STA 1oo2 Voting with High Availability
A customer has a Safety Instrumented Function they need to implement with two independent level transmitters (radar), each wired to a separate STA Functional Safety Trip Alarm. The process will trip if either level reaches the set point, for example a 1 out of 2 (1oo2) voting. However, if the alarm trip (STA) detects an input or unit fault. The customer did not want the process to trip. Instead they wanted to take the faulty unit out of service leaving the process running with the one good level and alarm trip.
