Inputs—Page 1
The inputs menu allows you to manage the detector’s physical and logical inputs. The
detector’s physical inputs are found on the detector’s wiring board, where there are six
input connectors (labeled Input 1–6). In contrast, the detector’s logical inputs are
controlled using the input menu, which allows you (the user) to tell the detector which
external input device is assigned to which input.
In addition, the inputs menu is used to assign a polarity (+ or –) to the voltage signal
received from your external input device, such as an in-feed photo eye. Assigning the
correct polarity is important, because an in-feed photo eye sends a positive or negative
voltage signal depending upon whether the photo eye is light or dark activated.

Example
Let’s look at an example. In a conveyor application, you have physically connected your
in-feed photo eye to Input 2 (the default set-up) on the detector’s wiring board. You
decide you want to move your in-feed photo eye Input 6, so you move the wires from
Input 2 to Input 6 on the detector’s wiring board, which is a physical change. Next, you
access the detector’s input function (described in this section) and tell the detector your
in-feed photo eye is now connected to Output 6, which is a logical (software-based)
change.
Navigating to Page 1 of the Inputs Menu
To navigate to page 1 of the inputs menu, do the following.
1)
Follow steps 1–4 in the “Inputs and Outputs” section above (pages 220–21).
2)
Press the right-navigation button to highlight the inputs menu.
