Signal behaviour

The safe state is the switched off state (unpowered
state: logical "0" on an OSSD).
If the actuating element is in the enable zone and
there is no sensor error, both output stages (OSSD)
are enabled (logical "1").
The output parameters are compatible with the
parameters for the input in compliance with
EN 61131D2 type 1 or 2:
Logical "1"
Logical "0"
If the actuating element is outside the enable zone,
the output is switched off (Logical "0").
Short-circuits between the two outputs will be
detected by the safety sensor and result in the
shutdown of the outputs (OSSD).
Short-circuits between the supply voltage and an
output will be detected and result in the shutdown of
the other output.
