Example of usage with only the internal relay
and monitored solenoid valves
Example of usage with external
contactors and feedback
Manual Reset: If selected, a reset can be requested each time the IN input signal drops
out. Otherwise the output is activated directly corresponding to the state of the IN input.
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.
Enable Status: If selected, the relay outputs can be connected to a STATUS.
Enable external K reading: If activated, the switching times for external contactors can be
read and checked:
For category 1 it is not possible to check the external contactors.
For category 4 the check on the external contactors is obligatory (always activat-
ed).
External K delay (ms): Set maximum delay on the contactors. Using this value the maxi-
mum delay between switching the internal relay and the switching of the external contac-
tors (on activation and deactivation) can be defined.
