Function (LOGIC 4)
● Safety inputs: X0, X1, X4, X5, X10 to X13 (T10 to T13)
X0, X1, X4, and X5 function as dual channel solid state inputs. These enable connections of dual
channel solid state output (PNP) devices.
X10 to X13 (T10 to T13) function as dual channel direct opening inputs.
The combinations of dual channel inputs are shown below. Incorrect use of these combinations
will result in an 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” and “Logic functions”.
X0 and X1: Safety input 1, X4 and X5: Safety input 2
X10-T10, X11-T11: Safety input 3, X12-T12, X13-T13: Safety input 4
Warning
Safety check signals (pulses signals) are transmitted from the drive terminals (T10 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, T1, T4, and T5.
Note: If there are unused safety inputs, for safety input 1 or safety input 2 (receive terminals:
X0,X1, X4, and X5), apply 24V DC to the terminals not connected to safety devices.
For safety input 3 and safety input 4 (receive terminals: X10 to X13, drive terminals: T10 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 its safety outputs.
● Muting inputs： X2, X3, X6, and X7
X2, X3, X6, and X7 function as muting inputs. Muting sensors (3wire, PNP output) or limit
switches can be connected as muting signal sources.
2 signals from Independent muting signal sources should be used for 1 muting input. The
combinations of inputs are shown below. Incorrect use of these combinations will result in an error.
When X2 and X3 are both ON, the safety function of safety input 1 is suspended.
When X6 and X7 are both ON, the safety function of safety input 2 is suspended.
Even if the safety input that is suspended has its safety functions turned OFF, the safety outputs
do not turn OFF.
The input monitor error detection time of muting inputs is 3s.
For information about connected control devices, see “SAFETY PRECAUTIONS” and “Logic functions”.
X2, X3: Muting input 1
X6, X7: Muting input 2
Warning
Muting inputs are not safety inputs. Do not use these to construct a safety system.
Note: Do not use T2, T3, T6, and T7
Note: If there are unused muting inputs, open those terminals.
Note: The maximum time to suspend the safety function continuously (muting monitor time) is 60s.
If muting continues over 60s, the muting function is disabled, even if the muting inputs are still ON.
