The input value and alarms are frozen while the logic input is closed.
With logic input closed, a reset turns OFF both the relay outputs and the alarms latch.
Input value is sampled; state of alarms is not transferred to outputs; outputs are "frozen".
When the logic input is active the input value is "frozen" and the outputs are updated according to the calculated alarms
state, including the ones latched.

For AL1 inverse absolute alarm (min.) with positive H1, 1 t = 1
(*) = OFF if disabling on power-on exists
For AL2 direct absolute alarm (max) with negative H2, 2 t = 0
Normal deviation alarm
(AL1 absolute, AL2 relative)
AL1+AL2
AL1
alarm 1
alarm 2
For AL1 direct absolute alarm (max) with negative H 1, 1 t = 0
For AL2 direct relative alarm (max) with negative H2, 2 t = 2
