Note1. The drive port generates check pulses in order to diagnose input devices and internal
circuits. (Wiring and the diagnostic function are different depending on the logic
selected. See “Chapter 5 LOGIC” for details. But the basic function is same.)
Note2. For cables longer than 30m between SafetyOne and connected devices, or wiring drive
terminals and receive terminals separately, use grounded shielded cables to assure
electromagnetic compatibility.
Note3. In the common connection of several interlock switches, applicable safety performance
depends on result of risk assessment for whole of the safety configuration. Refer to
ISO14119 for analysis the connection.
