Functions (Logic 1)
●Safety inputs: X0 to X13 (T0 to T13)
X0 to X13 (T0 to T13) function as dual channel direct opening inputs.
The combinations of dual channel inputs are as shown below. Incorrect use of these combinations
will result in an error. The input monitor error detection time between dual channel inputs is 0.5s.
For information about connected control devices, see “SAFETY PRECAUTIONS” and following
“Logic functions”.
X0-T0, X1-T1: Safety input 1
X2-T2, X3-T3: Safety input 2
X4-T4, X5-T5: Safety input 3
X6-T6, X7-T7: Safety input 4
X10-T10, X11-T11: Safety input 5
X12-T12, X13-T13: Safety input 6
Warning
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.
Note: Solid state outputs, such as safety light curtains, can not be connected.
Note: If there are unused safety inputs, short the receive terminals (Xn) corresponding to the
unused safety inputs and the drive terminals (Tn). If they are not shorted, the SafetyOne will not
turn ON the safety outputs.
●External device monitor inputs: X14 and X15 (T14 and T15)
X14 and X15 (T14 and T15) function as external device monitoring inputs.
X14 and T14 are used as contact monitoring for external devices connected to Y0 and Y1.
X15 and T15 are used as contact monitoring for external devices connected to Y2 and Y3.
Warning
Safety check signals (pulses signals) are sent from the drive terminals (T14, T15) to diagnose
external devices and monitor circuits. The safety check signal can not be used as a power supply
for connected devices.
Note: If there are unused safety outputs, short the external device monitor terminals (Xn)
corresponding to the unused safety outputs and the drive terminals (Tn). If they are not shorted,
the SafetyOne detects an input monitor error. As the result, the error LED displays a “1” and the
unit changes to the Protection state.
