Manual Reset: If selected, a reset can be requested on every activation of the movable guard or the safety door. Otherwise
the activation of the output will correspond directly to the input conditions.
There are two types of reset: "Manual" and "Monitored". On the selection of the manual reset, the system only checks the
signal transition from 0 to 1. With the monitored reset the double transition from 0 to 1 and then back to 0 is checked.
