Safety Input; T41 T42; Safety; T51 T52 - Omron G9SX Series Manual

Setting Procedure
1.Cross Fault Detection (Advanced Unit/Basic Unit)
Set the cross fault detection mode for safety inputs by shorting Y1 to
24 V or leaving it open. When cross fault detection is set to ON,
short-circuit failures are detected between safety inputs T11-T12 and
T21-22. When a cross fault is detected, the following will occur.
1. The safety outputs and logical AND outputs lock out.
2. The LED error indicator is lit.
3. The error output (auxiliary output) turns ON.

2.Reset Mode (Advanced Unit/Basic Unit)
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.Setting Logical AND Connection (Advanced Unit)
When connecting two or more Advanced Units (or Basic Units) by
logical AND connection, set the logical AND connection preset switch
on the Advanced Unit that is on the input side (Advanced Unit
G9SX-AD322 in the following diagram) to AND.
The default setting of the logical AND connection preset switch is set
to OFF.

Note: 1. A setting error will occur and Advanced Unit G9SX-AD322
will lock out if the logical AND setting switch on the Unit is
set to OFF.
2. Set the logical AND setting switch on Advanced Unit A to
OFF or an error will occur.
3. A logical AND input cannot be sent to a Basic Unit.

Note: 1. When not connecting Advanced Unit B, leave terminals T41
and T42 of the G9SX-ADA222 Advanced Unit open, and set
the logical AND setting switch T41/T42 to OFF.
2. When not connecting Advanced Unit C, leave terminals T51
and T52 of the G9SX-ADA222 Advanced Unit open, and set
the logical AND setting switch T51/T52 to OFF.
The following table shows the relationship between the logical ON
setting switches and the conditions for safety outputs turning ON.

4.Setting the OFF-delay Time (Advanced Unit)
The OFF-delay preset time on an Advanced Unit is set from the OFF-
delay time preset switch (1 each on the front and back of the Unit).
Normal operation will only occur if both switches are identically set. An
error will occur if the switches are not identically set.
The default setting of the OFF-delay time preset switch is set to 0 s.
