I'll go and get my specs. Maybe I've got the wrong end of the stick.

What is meant by ’Activate the control system’?
Are the system not allowed to perform control based on erroneous sensor data, i.e. have to perform fault insulation? (Logical)
Are the system not allowed to ‘Activate’ another control strategy, i.e. perform fault insulation by ‘failing silent’, and perform gracefully degradation like transitioning from Normal to Alternate mode? (Illogical)
Or are the system not allowed to ‘Activate’ another sensor channel, i.e. perform fault insulation by voting in another sensor, and thereby ‘Failing active’? (Illogical)
