1)
At least one of the two OSSD outputs is safely switched off during the response time.
2)
The risk time is the time needed to detect external faults. External errors affect the OSSD safety outputs
(shor
t-circuit to an OSSD safety output and cross-circuit between the two safety outputs). At least one of
the two OSSD outputs is safely switched off during the risk time. Note that the time for the safety require‐
ment (closing the protective device again) must be longer than the risk time.
3)
After the supply voltage has been switched on, the OSSD outputs and the application diagnostic output
are at Low potential during the time delay before availability. The time specified applies to one sensor; in
a cascade, 0.1 s must be added per sensor.
4)
Length of cable and cable cross-section change the voltage drop depending on the output current (R
max
=
14.5 Ω).
Application-related high input loads and long cable lengths may result in functional limitations of the
device.

9.2 Course of the OSSD test over time
The safety locking device tests the OSSDs for self-diagnosis at regular intervals. To
do t
his, the safety locking device switches each OSSD briefly to the OFF state and
checks whether this channel is voltage-free during this time.
Make sure that the machine’s control does not react to these test pulses and the
machine does not switch off.
