Manual I/O Test
Press Yes at this prompt to see menus which can help you test the digital
inputs, digital outputs and the controller’s keypad.
Below is the manual I/O menu tree.
Digital Input Testing
Use this menu to view the logic state of the 8 digital inputs as H (High--
the input is at 5 volts or is not connected) or L (Low--the input is at zero
volts). The menu displays inputs 1 to 8 from left to right. Since inputs
are pulled High when they are not connected, test an input by shorting it
to controller common and making sure this menu shows the correct state
for that input.
Using This Menu
• Short the digital input you are testing to controller common. When
you do that, the input's state should change to L.
• Press Yes or No to advance to the next menu.
• Press Back to return to the Manual I/O test main menu.
