Wiring of Inputs and Outputs
Terminal
Signal Name
Name
A1,
Power supply
Connect the power source to Terminals A1 and A2.
A2
input
T11,
Enable
To set Safety solid-state outputs in ON state in the
T12
input CH1
Maintenance mode, HIGH state signals must be
input to both of Enable input CH1 and Enable input
CH2 Otherwise Safety solid-state outputs cannot
be in ON state.
Enable
T21,
input CH2
T22
Safety
T61,
To set Safety solid-state outputs in ON state in
input CH1
T62
the Normal operating mode, HIGH state signals
must be input to both of Safety input CH1 and
Safety input CH2 Otherwise Safety solid-state outputs
T71,
cannot be in ON state.
Safety
T72
input CH2
To set Safety solid-state outputs in ON state,ON state
Feedback/
T31,
signal must be input to T33.
T32,
Reset input
Otherwise Safety solid-state outputs cannot be in
T33
ON state.
To set Safety solid-state outputs in ON state,the signal
input to T32 must change from OFF state to ON state,
and then to OFF state.
Otherwise Safety solid-state outputs cannot be in
ON state.
Logical AND connection means that lower unit(Unit B)
T41,
Logical AND
calculates the logical multiplication (AND) of the safety
T42
connection
output information from upper unit(Unit A) and safety
input
input signal "b", which is input to lower unit.In the
example of a right picture, the safety output of Unit C is
"a" AND "b" .
Connect L1 or L2 of upper unit to T41 of lower unit, and
connect GND of upper unit to T42 of lower unit.
To set Safety solid-state outputs of the subsequent
Unit in ON state, its Logical AND Connection Preset
Switch must be set to AND (enable) and High state
signal must be input to T41 of the subsequent unit.
Mode
M1,
Either Safety input or Enable input is effectively done by
selector
M2
1NC1NO input.
The relationship between Safety/Enable input and
input
Mode selector inputs is as follows;
M1=ON,M2=OFF Safety input detection
M1=OFF,M2=ON Enable input is enabled(Maintenance mode)
Rotation
D11,
Normal operation mode: To turn on Safety speed
detection outputs, pulse signals from the two
detection
D12,
proximity sensors monitoring should be 2.0Hz or less.
input
D21,
Maintenance mode: To turn on Safety speed
D22
detection outputs, the signal frequency from
the two proximity sensors should be lower than
the preset Low speed monitoring frequency.
Y1,
Selects a mode of failure detecting (Cross
Cross fault
Y2
fault detecting) function for safety inputs of
detection input
G9SX-LM corresponding to the
connection of Cross fault detection input.
Turns ON/OFF according to the state of safety

During off-delay state, safety solid-state outputs
are not able to turn ON.
