24. Set the time duration of OFF-delay to an appropriate value that
does not cause the loss of safety functions of system.
25. Logical AND connections between Units (Refer to “Functions” on
page 23.)
1. To use logical AND connection inputs, enable the logical AND
connection input for the G9SX-NS@ that will receive the inputs.
2. Connect the logical AND connection inputs appropriately to the
logical AND connection outputs of the G9SX-@.
3. When configuring the safety system, be sure to consider that
the delay of response time caused by logical AND connection
does not degrade the safety functions of the system. (Refer to
“Response Time and Operating Time” on page 17.)
26. 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 D40A Non-contact Door Switch inputs
3. Response time of logical AND connection input
(Refer to “Response Time and Operating Time” on page 17.)
4. Preset OFF-delay time
5. Accuracy of OFF-delay time
27. Start the rest of the system after 5 s or longer has passed since
applying supply voltage to all G9SX-@ in the system.
28. Be sure to ground the A2 terminal of the power supply to help
prevent malfunctions caused by noise. Also, connect a surge
absorber to each end of the coil on inductive loads to reduce noise
generation. When sharing a power supply with a Light Curtain,
use a DC power supply that will not fail for a momentary power
interruption of 20 ms or less.
29. Devices connected to the G9SX-NS may operate unexpectedly.
When replacing the G9SX-NS, disconnect it from power supply.
30. Adhesion of solvent
Do not allow organic solvents, such as alcohol, thinner,
trichloroethane, or gasoline, to come into contact with the product.
Such solvents make the markings on G9SX-NS illegible and
cause deterioration of parts.
31. Do not mix AC and DC circuits for contact outputs in a single
G9SX-EX@-@. When using AC and DC circuits, connect at least
two G9SX-EX@-@ Units and use them respectively as dedicated
DC-circuit and AC-circuit contact outputs.
32. Safety Application Controller’s Relay durability depends greatly
on the switching condition. Confirm the actual conditions of
operation in which the Relay will be used in order to make sure the
permissible number of switching operations.
When the accumulated number of operation exceeds its
permissible range, it can cause failure of reset of safety control
circuit. In such case, please replace the Relay or the Safety
Application Controller immediately.
If the Relay or the Safety Application Controller is used
continuously without replacing, then it can lead to loss of safety
function.
33. 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.

Safety Categories
You can use the D40A with the G9SX-NS@ for applications in PLd
and Safety Category 3 environments defined in the EN ISO13849-1
European standard and the ISO 13849-1 international standard.
Compliance was determined using circuit examples specified by
OMRON and may not be applicable to all conditions.
Safety categories are determined for the overall safety control
system. Confirm compliance sufficiently with your application.
Requirements for Safety Category 3 (ISO 13849-1)
1. Connect external input D1-D2 and external output D3-D4 to D40A
Switches.
2. Input two channels for external inputs T11-T12 and T21-T22.
3. Input external inputs T11-T12 and T21-T22 from switches with
direct opening mechanisms. For limit switches, make sure at least
one of the switches has a direct opening mechanism.
4. Input the NC signal from the contactor to T31-T32 for a manual
reset and to T31-T33 for an auto reset. (Refer to “Application
Examples” on page 28)
5. Make sure to connect the A2 terminal to ground.
