Performance Level and Safety category of EN ISO13849-1
The G9SX-LM can be used for PL=d and Category 3 required by EN ISO13849-1 European standard.
Refer to the following link for the Safety-related characteristic data:
http://www.fa.omron.co.jp/safety_6en/
However, please note that this does not mean that G9SX can be always used for this category under all similar conditions or situations.
Be sure to assess the entire system for conformity to a required category before use.
For conformity to Safety Category 3, please check the following points;
1) Use both of the two channels for Enable inputs (T11-T12, T21-22), Safety inputs (T61-62, T71-T72), and Rotation detection inputs (D11-D12, D21-D22).
2) Use direct opening action switches for safety inputs (T61-T62, T71-T72).
When limit switches are used, at least one of them should be a direct opening action limit switch.
When connecting a Safety Sensor to the G9SX-LM, use a TYPE3 or 4 Safety Sensor.
3) Use an enabling device, such as grip-switch, for Enable inputs (T11-T12, T21-T22)
4) Connect specified Proximity sensors to Rotation detection inputs (D11-D12, D21-D22)
5) Apply input signals to T31-T32 for manual reset, or T31-T33 for auto-reset, through the N.C. contact. (Refer to '5. Application Examples)
6) Be sure to connect A2 to ground.

Fault Detection
When G9SX-LM detects a fault, ERR indicator and/or other indicators light up or blink to show the information of the fault.
Check and take needed measures referring to the following table, and then apply supply voltage to G9SX-LM.
