Warning
For connected control devices, refer to “SAFETY PRECAUTIONS”.
Safety check signals (pulses signals) are sent from the drive terminals (T0 to T13) to diagnose
connected safety devices and input circuits. Safety check signals can not be used as a power supply
for connected devices.
In case of using only safety input 1 or safety input 2, open the unused safety inputs. This is the same
for safety input 3 and safety input 4. If unused safety inputs are connected, SafetyOne does not turn
OFF by the OFF operation of used safety inputs.
Note. Solid state outputs, such as safety light curtains, can not be connected.
Note. Use safety inputs 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 although safety input 1 is
in ON state, SafetyOne detects error and transits to Protection state.
Note. When both of safety input 1 and safety input 2 are unused, connect one of the unused receive
terminal (Xn) to the corresponding drive terminal (Tn) at least. If they are not connected, the
SafetyOne does not turn ON the safety outputs.
Note. When both of safety input 3 and safety input 4 are unused, connect one of the unused receive
terminal (Xn) to the corresponding drive terminal (Tn) at least. 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.
