Figure 66: Configuration of 2-channel outputs
(category 4)
Figure 67: Configuration of 4 single-channel outputs
(category 4)
Manual Reset: If selected, a reset can be requested each time the IN input signal drops out. Otherwise the activation of the
output follows the input conditions directly.
Manual Monitored
Figure 68: Manual/monitored reset
There are two types of reset: Manual and Monitored. On the selection of the manual reset, only the signal transition from 0
to 1 is checked. With the monitored reset the double transition from 0 to 1 and then back to 0 is checked.
Enable Status: If selected, the actual status of the OSSD can be connected to any point in the diagram.
External K time monitoring: If selected, the time window for monitoring the external feedback signal (on the state of the
output) can be set.
