On the device plug.
13)
In the case of a fault (0 V cable open circuit) the maximum leakage current flowing in the OSSD cable. The
downstream controller must detect this status as LOW. A FPLC (fail-safe programmable logic controller) must
be able to identify this status.
14)
The maximum rated load inductance is higher with lower switching sequence.
15)
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 when using the above parameters.
16)
Maximum power consumption of a system with 1200 mm protective field height and a resolution of 14 mm.
