Functions (Logic 2)
● Safety inputs: X0 toX13 (T0 to T13)
X0 to X7 (T0 to T7) function as dual channel NO/NC inputs.
X10 to X13 (T10 to T13) function as dual channel direct opening inputs.
The combinations of the dual channel inputs are 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”
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 transmitted from the drive terminals (T0 to T13) to
diagnose connected safety devices and input circuits. Safety check signals can not be used as
power for connected devices. In case of use of non-contact interlock switches with LEDs, refer to
the “Wiring example (Logic 2)” for wiring with IDEC non-contact interlock switches HS7A series as
S1, S2, S5 and S6.
Note: Solid state outputs, such as safety light curtains, can not be connected.
Note: If there are unused safety inputs, short or open between the receive terminals (Xn)
corresponding to the unused safety inputs and the drive terminals (Tn) as shown below. If this is
not done, then the SafetyOne will not turn ON the safety outputs.
Open： X0-T0, X2-T2, X4-T4, X6-T6
Short： X1-T1, X3-T3, X5-T5, X7-T7, X10-T10, X11-T11, X12-T12, X13-T13
● External device monitor inputs： X14 and X15 (T14 and T15)
X14 and X15 (T14 and T15) function as external device monitor 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 monitor circuits. The safety check signal can not be used as the
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.
