Figure 34
shows the characteristics of SWS signal when it is active. It starts
with a 1 ms pulse, followed 700 µs later by a 500 µs wide pulse. This waveform
is repeated every 4 ms. The tolerance of all edges is ±10%.
When inactive, the SWS signal is 0V.

The DG safety relay has two voltage-free, safety-related outputs (terminals
13/14 and 23/24).
13/14 and 23/24 Safety Outputs
The 13/14 and 23/24 safety outputs have redundant (two) positive-guided
relays that are internally connected between each terminal. An example of the
wiring connections is shown in
voltage and current ratings of these relays.
If the voltage supply of the outputs exceeds the voltage supply of the relay, then
low-voltage wiring must be separated from the high-voltage wiring.
