@
)
Set the cross fault detection mode for safety inputs
b
y shorting Y1
to 24 V or leaving it open.
When cross fault detection is set to ON, short-circuit failures are
detected
b
etween 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 (G9SX-NS202-

2,
and T
33
.
Auto reset mode is selected when terminal T

is shorted
to 24 V.

When connecting two or more Non-contact Door Switch
Controllers
b
y 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. The default setting of the
logical AND connection preset switch is set to OFF.
Note:
A setting error will occur and Unit B will lock out if the logical
AND setting switch on the Unit B is set to OFF.

The OFF-delay preset time on G9SX-NSA222-T0
3

@
is set from
the OFF-delay time preset switch (1 each on the front and
b
ack of
the Unit).
Normal operation will only occur if
b
oth 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.
Refer to the following illustration for details on setting switch positions.
