Start input equivalent circuit
Start input operating range
The specifications of the start inputs changes depending on the Logic selected. See further
information in “Chapter 5 LOGIC”. But basic specifications are same.
Warning
Do not use start inputs as safety inputs. This may cause the loss of safety functions and
possible failure in the SafetyOne or peripherals.
