The 7Ćsegment LED provides detailed information on the status of the
module. If the LED displays any number from 0" through 9"
inclusive or b," the module is malfunctioning and has not passed
one of its powerĆup diagnostics. Three other possible displays
indicate that the module has not been set up properly or that there is
a fault somewhere else in the system. See figure 2.2 for an
explanation of fault codes.
