– State of the actuator
– State of the inputs
– Supply voltage/fault

Function description
The safety outputs may have a high or low signal, depending on the position of the actuator
and the signal status of the inputs.
In a safe condition there is a low signal at the safety outputs.
Electrical states of the inputs and outputs (when switch is ready for operation:
Power / Fault LED is green):

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 [ 22]).
} Diagnostic input Y1
If a fieldbus module of the SDD is used, the diagnostic input Y1 is automatically activ-
ated and data is read.
If no fieldbus module of the SDD is used, the diagnostic input Y1 is not used.
