at the end position. When Advanced Unit is used without expansion
units, leave the termination connector set on the Advanced Unit.
2) Do not remove the termination connecter while the system is operating.
3) Before applying supply voltage, confirm that the connecting
sockets and plugs are locked firmly.
4) All of the Expansion Units should be supplied with its specified
voltages within 10s after the connected Advanced Unit is supplied
with voltage.
Otherwise, Advanced Unit detects the power-supply error for the
Expansion Units.
(7) Use cables with length less than 100m to connect to Safety Inputs,
Feed-back/Reset inputs, or between Logical AND connection inputs
and Logical connection outputs, respectively.
(8) Set the time duration of OFF-delay to an appropriate value that does
not cause the loss of safety function of system.
(9) Logical connection between Units:
1) When using Logical AND connection inputs, set the Logical
connection preset switch to 'AND' position for the units which the
logical connection signal are input to.
2) Connect Logical connection outputs appropriately to Logical AND
connection inputs of the relevant unit. Verify the operation of G9SX
before commissioning the system.
3) When configuring the safety related system, be sure to consider
that the delay of response time caused by logical connections do
not degrade the safety function of the system.
(10) To determine safety distance to hazards, take into account the delay
of Safety outputs caused by the following time:
1) Response time of Safety inputs
2) Response time of Logical AND connection input
(See also "Ratings and specifications, note5")
3) Preset off-delay time
4) Accuracy of off-delay time
(11) Start entire system after more than 5s have passed since applying
supply voltage to all G9SXs in the system.
(12) G9SX may malfunction due to electro-magnetic disturbances.

When using a DC power supply with light curtains, use DC power
supply which has no interruption by a power failure of 20ms.
(13) Devices connected to G9SX may operate unexpectedly.
When replacing G9SX, disconnect it from power supply.
(14) Adhesion of solvent such as alcohol, thinner, trichloroethane or
gasoline on the product should be avoided. Such solvents make the
marking on G9SX illegible and cause deterioration of parts.
(15)This is a class A product. In residential areas it may cause radio
interference, in which case the user may be required to take
adequate measures to reduce interference.
(16) Operate the reset input more than 0.4 seconds immediately after the
safety outputs are OFF.
G9SX does not accept the reset input from when the outputs are
turned ON and until 0.4 seconds passes after the outputs are turned
OFF.

Description of operation Wiring
Keep Y1 open when using T11, T21. (Wiring corresponding
to category 4)
ConnectY1 to 24VDC when NOT usingT11, T21.
(Wiring corresponding category 2 or 3, or when connecting
safety sensors and corresponding up to category 4.)
Logical AND connection means that lower unit
(Unit B) calculates the logical multiplicatin (AND)
of the safety output information from upper unit
(Unit A) and safety 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
lowre unit.

Terminal arrangement and LED indicators
The G9SX can be used up to PL =e and Category 4 required by EN ISO 13849-1 European standard. Refer to the following link for the
Safety-relay characteristic data:
http://www.fa.omron.co.jp/safety_6en/
This does NOT mean that G9SX can always be used for required category under all the similar conditions and situations.
Conformity to the categories must be assessed as a whole system.
When using G9SX for safety categories, make sure the conformity of the whole system.
1) Input the signals to both of the Safety inputs (T11-T12 andT21-T22)
2) Input a signal to the Safety inputs (T11-T12 andT21-T22) through switches with Direct Opening Mechanism.
When using limit switches, at least one of them must have Direct Opening Mechanism.
3) When connecting Safety sensor with G9SX, use TYPE 4 safety sensor.
4) Input the signal through a NC contact of the contactor to Feedback/Reset input (T31-T32 for manual reset orT31-T33 for auto reset). (Refer to
'5.Examples of Application')
5) Keep Cross fault detection mode input (Y1) open. However, when connecting devices with self-diagnosis function, such as safety sensors,
apply 24VDC toY1.
6) Be sure to Connect A2 to ground.
