Instead of the safety switching device manufactured by Sick mentioned above, you
may use other safety switching devices.
The safety switching device must however provide the following features:
1 normally open contact is required for switching off channel 1
(as an alternative, a safe semiconductor output is possible)
1 off-delayed normally open safety contact is required for switching off channel 2
(as an alternative, a safe semiconductor output with adjustable delay time for the
high_to_low_edge is possible).
1 one-channel monitoring circuit where the feedback contacts of channels 1 and
2 can be integrated for simultaneous monitoring, is required.
At the same time it must be possible to integrate a one-channel start button for
activation of the safety switching device into the circuit.
A new start may only be successful, if it is ensured, that channels 1 and 2 are
switched off.
1 two-channel connection for emergency power off and/or safety door contacts
with cross fault monitoring is required.
The safety switching device must feature performance PL e. The I/Os must at
least correspond to category 3.
