Warning
Safety check signals (pulses signals) are sent from the drive terminals (T14, T15) to diagnose external
devices and monitor circuits. Safety check signals can not be used as a power supply for connected
devices.
Note. If there are unused safety outputs, connect the intended external device monitor terminals (Xn)
to the corresponding drive terminals (Tn). If they are not connected, the SafetyOne detects an
input monitor error. As the result, the error LED displays a “1” and the unit changes to the
Protection state.
●Start inputs: X16 and X17
Start inputs are used to control the start of safety outputs.
