Warning
For connected control devices, refer to “SAFETY PRECAUTIONS”.
Safety check signals (pulses signals) are sent from the drive terminals (T0, T1, T4, T5 and T10 to T13)
to diagnose connected safety devices and input circuits. Safety check signals can not be used as a
power supply for connected devices.
Note. Solid state outputs, such as safety light curtains, can not be connected to safety input 1, safety
input 3, safety input 5, and safety input 6.
Note. Use safety input 1, safety input 3, safety input 5, and safety input 6 as specified combinations,
such as receive terminal (Xn) and drive terminal (Tn). If the combinations are incorrect,
SafetyOne does not work correctly.
Note. When SafetyOne is in Run state or Protection state, input states are monitored in all safety
inputs. For example, if input monitor error is detected in safety input 2 or safety input 3 although
safety input 1 and safety input 2 are in ON state, SafetyOne detects error and transits to
Protection state.
Note. If using only safety input 1 of safety input 1 and safety input 2, connect the unused receive
terminals (X2 and X3) to a 24V DC power supply (V+). If using only safety input 2, connect the
unused receive terminals (X0 and X1) to the corresponded drive terminals (T0 and T1). If using
only safety input 3 of safety input 3 and safety input 4, connect the unused receive terminals
(X6 and X7) to a 24V DC power supply (V+). If using only safety input 4, connect the unused
receive terminals (X4 and X5) to the corresponding drive terminals (T4 and T5). If they are not
connected, the SafetyOne does not turn ON the safety outputs.
Note. When safety output 5 or safety output 6 is unused, connect the unused receive terminal (Xn) to
the corresponding drive terminal (Tn). If they are not connected, the SafetyOne does not turn
ON the safety outputs.
