(c) Wiring example for external pulse input to safety signal module.
The wiring diagram for external pulse input signal and safety signal module
shows below.
Safety module performs the safety diagnostics of external pulse generator,
therefore you need to wire them so that external pulse generator is supplied
power by the safety signal module, and the generated pulse becomes input
signal of safety signal module.
