Performance Level and Safety category of EN ISO 13849-1
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 and T21-T22)
2) Input a signal to the Safety inputs (T11-T12 and T21-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 or T31-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 to Y1.
6) Be sure to Connect A2 to ground.

Fault Detection
When G9SX 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.

To set Safety solid-state outputs in ON state,
Auto reset
ON state signal must be input to T33.
Otherwise Safety solid-state outputs cannot
be in ON state.
To set Safety solid-state outputs in ON state,
Manual reset
the signal input to T32 must change from
OFF state to ON state, and then to OFF state.
Otherwise Safety solid-state outputs cannot
be in ON state.
Logical AND connection means that lower unit
Unit A
(Unit C) calculates the logical multiplication (AND)
of the safety output information from upper unit
(Unit A, Unit B) and safety input signal "c", which
output(a)
is input to lower unit.
In the example in the right, the safety output of
Unit C
Unit C is "a" AND "b" AND "c".
Connect L1 or L2 of upper unit to T41 or T51 of
