Note1. For cables longer than 30m between SafetyOne and connected devices, use grounded
shielded cables to assure electromagnetic compatibility.
Start input equivalent circuit
Start input operating range
Operating specification of start inputs are different depending on the configured logic number.
For more details, refer to “Chapter 5 LOGIC”. But the basic input specifications are not
changed.
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.
