Functions (Logic 3)
●Safety inputs: X0 to X13 (T4 to T13)
X0 to X3 function as dual channel solid state inputs. These enable the connection of dual channel
solid state output (PNP) devices.
X4 to X13 (T4 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 error. The input monitor error detection time for dual channel solid state inputs is 0.1 s.
The input monitor error detection time for dual channel direct opening inputs is 0.5 s.
For information about connected control devices, see “SAFETY PRECAUTIONS” following “Logic
functions”.
X0, X1: Safety input 1
X2, X3: 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 transmitted from the drive terminals (T4 to T13) to
diagnose connected safety devices and input circuits. Safety check signals can not be used as
power for connected devices.
Note: Don’t use T0 to T3.
Note: If there are unused safety inputs, for safety input 1 or safety input 2 (receive terminals: X0 to
X3), apply 24V DC to the terminals not connected to safety devices.
For safety input 3 to 6 (receive terminals: X4 to X13, drive terminals: T4 to T13), short between
the receive terminal (Xn) and the drive terminal (Tn).
If this is not done, then 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 monitors for external devices connected to Y0 and Y1.
X15 and T15 are used as contact monitors for external devices connected to Y2 and Y3.
Warning
Safety check signals (pulses signals) are transmitted from the drive terminals (T14,T15) to
diagnose external devices and monitoring circuits. The safety check signal can not be used as
power for connected devices.
Note: If there are unused safety outputs, short between 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 “1”
and the state changes to the Protection state.
