Omron G9SX Series Manual page 48

11. Start entire system after more than 5 s have passed since
applying supply voltage to all G9SXs in the system.
12. Power Supply
(1) The G9SX may malfunction due to electromagnetic
disturbances. Be sure to connect terminal A2 to ground.
(2) When sharing a power supply with a Safety Light Curtain, use
a power supply that will not fail for a momentary power
interruption of 20 ms or less.
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. Do NOT mix AC load and DC load to be switched in one G9SX-
EX@-@. When switching of both AC load and DC load is
necessary, connect more than two G9SX-EX@-@ and use each
unit for AC load and DC load exclusively.
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.

1. Use a mode selector that has an SPST-NO + SPST-NC contact
form (e.g., OMRON's A22K-@-11-@@).

Safety Category (EN ISO 13849-1)
In the condition shown in Application Examples, G9SX can be used
for the corresponding categories up to Safety category 4 per EN
ISO13849-1.
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, be sure to confirm the
conformity as a whole system.
Applicable Safety Category 4 (EN ISO13849-1)
1. Input signals to both safety inputs (T11-T12, T21-T22, T61-T62,
and T71-T72).
2. Input signals to the safety inputs (T11-T12, T21-T22, T61-T62, and
T71-T72) through switches equipped with a direct opening
mechanism.
When using limit switches, at least one of them must have a direct
opening mechanism.
3. When connecting a Safety Sensor to the G9SX, use a TYPE 4
Safety Sensor.
4. Input the signal through a NC contact of the contactor to Feedback/
Reset input (T31-T32 for manual reset or T31-T33 for auto reset).
5. Keep the cross fault detection mode input (Y1 and Y2) open.
However, when connecting devices that have a self-diagnosis
function, such as Safety Sensors, apply 24 VDC to Y1 or Y2.
6. Be sure to connect A2 to ground.
7. When using a G9SX-EX@-@ Expansion Unit, connect fuses with a
current rating of 3.15 A maximum to the safety relay outputs to
prevent the contacts from welding.
