Setting Procedure - Omron G9SX Series Manual

Setting Procedure

1. Cross Fault Detection (G9SX-NSA222-T03-@)
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.

OFF Corresponds to
Safety Category 2

Safety Category 3
ON Corresponds to
Safety Category 3
(Cross fault

(for safety inputs)).
2. Reset Mode (G9SX-NS202-@/NSA222-T03-@)
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 (G9SX-NS202-@/
NSA222-T03-@)
When connecting two or more Non-contact Door Switch
Controllers by logical AND connection, set the logical AND
connection preset switch on the Controller that is on the input side
(Unit B in the following diagram) to AND.
Unit A
L1
T41
Unit B
Note: A setting error will occur and Unit B will lock out if the logical
AND setting switch on the Unit is set to OFF.
4. Setting the OFF-delay Time (G9SX-NSA222-T03-@)
The OFF-delay preset time on G9SX-NSA222-T03-@ 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.
