Input Module LEDs
Each input module has 5 Green LEDs located on the front edge of the board. The LEDs indicate
the status of the module’s voltage. All 5 LEDs must be lit for the module to operate properly. The
absence of any lighted LED indicates a failure of the module and the factory should be contacted.
Just behind the reset button there is a group of 6 LEDs used for de-bug purposes. The function of
the LEDs are described below.
