G9SX-GS
Setting Procedure
1.Switching Function
Auto or manual switching is set by using the Switching Function
setting switch on the bottom of the G9SX-GS@. Set the switch to Auto
for auto switching and Manual for manual switching.
For manual switching, connect the mode selector as shown in the
following table.
2.Reset Mode
Set the reset mode using feedback/reset input terminals T31, T32,
and T33.
Auto reset mode is selected when terminal T32 is shorted to 24 V and
manual reset mode is selected when terminal T33 is shorted to 24 V.
3.Cross Fault Detection
When connecting a Door Switch or other safety input device, you can use Y1 or Y2 to switch the cross fault detection setting.
When Y1 is open, short-circuit failures are detected between safety inputs T11-T12 and T21-T22. When Y2 is open, short-circuit failures are
detected between safety inputs T61-T62 and T71-T72. When a cross fault is detected, the following will occur.
1. The safety outputs and logical AND output will be locked out.
2. The LED error indicator will light.
3. The error output (auxiliary output) will turn ON.
When a safety sensor, such as a Safety Light Curtain, is connected to safety input A, connect Y1 to 24 V. When a safety sensor is connected to
safety input B, connect Y2 to 24 V. If they are not connected to 24 V, the G9SX-GS@ will detect an error.
