Once the supply voltage has been switched on, the OSSDs and the application diagnostic output are in
t
he OFF state during the time delay before availability. The specified time applies to one sensor; in a
series connection, 0.1 s must be added per sensor. An additional 0.5 s per taught-in actuator must be
added for uniquely coded and permanently coded sensors.
