The G9SX-SM



can be used for PL=e and Category 4 required by EN ISO 13849-1 European standard.

Refer to the following link for the Safety-related characteristic data:
http://www.fa.omron.co.jp/safety_6en/
This does NOT mean that G9SX-SM 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-SM for safety categories, be sure to confirm the conformity as a whole system.
For conformity to Safety Category 4, please check the following points;

1) Connect a fuse to each of the Standstill detection input lines.
2) Provide signals of different phases for the Standstill detection inputs (Z1-Z2, Z3-Z4).
3) Connect Guard lock Safety-door switches to any one of Safety Standstill detection outputs: ES1, ES2 or ES3.
4) Input the signal through a NC contact of the contactor to EDM input T31-T32. (Refer to '6. Application Examples')
5) Be sure to connect A2 to ground.

1) Check the disturbance level around

G9SX-SM and its related system.

2) Replace with a new product.
1) Check the wiring to Z1 and Z2.
2) Set the brake time at less than 30 seconds
3) Replace with a new product.

1) Check the wiring to Z3 and Z4.
2) Set the brake time at less than 30 seconds
3) Replace with a new product.

1) Frequency of standstill detection input is out of

range.

1) Confirm the operation frequency of the

motor is 120Hz or less.

1) Check the wiring to T31 and T32
2) Separately wire to T31 and T32 from the

power line etc., of the inverter.

3) Replace with a new product.

1) Failures involving the wiring of EDM input.
2) Excessive electro-magnetic disturbance

3) Failures of the parts of the circuits of EDM input

1) Incorrect set values of Standstill detection time

preset switches.

2) Failures of the parts of the circuits of mode settings.
