Operation at error detection
When the module detects an error in a diagnostic of the output dark test function, the minor error (output dark test error) state
is applied and all output points are turned off. For details on the minor error state, refer to the following.
Page 95 Error Code List
Setting procedure
Set the following parameters for the output dark test function.
■Output mode setting
Set whether to perform the output dark test function or not in "Output mode setting" from the "Parameter Processing of Slave
Station" window of the engineering tool.
For the procedure to display the "Parameter Processing of Slave Station" window, refer to the following.

NZ2GFS12A2-14DT
Output mode setting Y0+/Y0-/Y1+/Y1-
• For the NZ2GFS12A2-16DTE, when "Wiring selection of output" is set to "1: Double wiring", set the same
value for both Yn and Yn+1.
• When "Output mode setting" is set to "1: Not used", the output value is always OFF.
• Set the same value to both "Output mode setting" (Yn) and "Output mode setting" (Yn+1) regardless of the
setting of "Wiring selection of output" (Yn/Yn+1).
■Output dark test pulse time
Set the output dark test pulse time in "Output dark test pulse time" from the "Parameter Processing of Slave Station" window
of the engineering tool.
For the procedure to display the "Parameter Processing of Slave Station" window, refer to the following.

• Adjust the output dark test pulse time depending on the installation environment or wiring length.
• For "Output dark test pulse time", using the default value is recommended because almost any applications
can operate with "Output dark test pulse time" set to the default value.
