6)
In the case of a fault (0 V cable open circuit), no more than the specified leakage current flows in the
O
SSD cable. The downstream control element must detect this state as LOW. An FSPLC (fail-safe pro‐
grammable logic controller) must detect this state.
7)
If the switching sequence is low, the maximum permissible load inductance is higher.
8)
Make sure to limit the individual conductor resistances to the downstream controller to this value to
ensur
e that a cross-circuit between the outputs is safely detected. (Also note EN 60204-1.)
9)
When active, the outputs are tested cyclically (brief LOW). When selecting the downstream controllers,
make sure that the test pulses do not result in deactivation.
