9)
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 safe PLC (Programmable Logic Controller) must be
able to identify this status.
10)
Make sure to limit the individual cable resistance to the downstream controller to this value to ensure that a
cross-circuit between the outputs is safely detected. (Also note EN 60 204 Electrical Machine Equipment,
Part 1: General Requirements.)
11)
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.
