Use the following steps to view the status of an analog output.
Illustration 1 g02270495
Use the navigation keys in order to select "VIEW" at the main menu screen. Refer to Illustration 1.
Press the "OK" key.
Illustration 2 g03005778
Use the navigation keys in order to select "I/O STATUS" at the view screen. Refer to Illustration 2.
Press the "OK" key.
Illustration 3 g02270497
Use the navigation keys in order to select "ANALOG OUTPUTS" at the I/O status screen. Refer to Illustration 3.
Press the "OK" key.
Illustration 4 g02270499
The status of each analog output is shown in Illustration 4. A "dash" under an output number indicates the output is programmed, but is inactive. A large "X" under an output number indicates the output is disabled. A number under an output number indicates the output is programmed and is active.
Use the navigation keys in order to select the desired analog output that is to be viewed. Press the "OK" key.
