1)
Output circuits: These contacts must be incorporated into the control such that the dan‐
gerous state is brought to an end if the output circuit is open. For categories 4 and 3, they
must be incorporated on dual-channels (x, y paths). Single-channel incorporation into the
control (z path) is only possible with a single-channel control and taking the risk analysis
into account.
2)
PELV in accordance with the requirements of EN 60204-1 / 6.4 Optical short-circuits
must be avoided. Observe the operating instructions of the integrated devices. The safety-
related parameters (safety integrity level and response time) are dependent on the types
used.
