Applies to the voltage range between –30 V DC and +30 V DC.
15)
Switch off time represents the minimum amount of time that the OSSDs will be switched off when the C4000
Select transitions to an inactive (low) (i.e. red) state.
16)
As per IEC 61131@2.
17)
On the device plug.
18)
In the case of a fault (0 V cable open circuit) the max. leakage current flows in the OSSD cable. The down-
stream controller must detect this status as LOW. A FPLC (Fail-safe Programmable Logic Controller) must be
able to identify this status.
19)
The maximum rated load inductance is higher with lower switching sequence.
20)
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.
21)
Make sure to limit the individual line core resistance to the downstream controller to this value to ensure that
a short-circuit between the outputs is safely detected. (Also note EN 60 204 Electrical Machine Equipment,
Part 1: General Requirements.)
