Feasibility monitoring for safety inputs S11 and S21
} If one safety input switches from high to low, while the other safety input remains high,
an unequal status is displayed: Input LED flashes yellow
} If this safety input switches back from low to high, while the other safety input remains
high, a feasibility error is displayed and a partial operation lock is triggered: Input LED
flashes yellow
A switch to a high signal will only lead to normal switch operation if both inputs had a low
signal. From this moment on, the switch to high may occur (partial operation lock see Error
display [ 16]).
