Warning
For connected control devices, refer to “SAFETY PRECAUTIONS”.
Safety check signals (pulses signals) are sent from the drive terminals (T0 to T11) 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 inputs.
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. If there are unused safety inputs, connect the unused receive terminals (Xn) to the
corresponding drive terminals (Tn). If they are not connected, the SafetyOne does not turn
ON the safety outputs.
