4.Diagnostic Checks of External Indicators
Diagnostic checks of external indicators connected to external
indicator outputs UA and UB can be switched with Y3 and Y4,
respectively. Enabling the diagnostic check makes it possible to
detect indicator burnout or wiring errors.
If there is no indicator connected to external indicator output UA,
connect Y3 to 24 V. If there is no indicator connected to external
indicator output UB, connect Y4 to 24 V. If they are not connected to
24 V, the G9SX-GS@ will detect an error.
Note: Diagnostic checks cannot be made for LED indicators. Disable
the diagnostic check if using LED indicators.
5.Setting Logical AND Connection
When connecting two or more Units using a logical AND connection,
set the logical AND connection preset switch on the Unit that is on the
input side to AND.
The default setting of the logical AND connection preset switch is set
to OFF.
Note: 1. A setting error will occur and Unit B will lock out if the logical
AND setting switch on Unit B is set to OFF.
2. Set the logical AND setting switch on Unit A to OFF,
otherwise the Unit A output will not turn ON.
6.Setting the OFF-delay Time
The OFF-delay preset time 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.
Refer to the following illustration for details on setting switch positions.
