A red FAULT LED indicates an error situation and, when noted with
the other indicator LEDs, can indicate a specific problem area.
Table 1
describes signal output and LED indications for the various input/ref-
erence combinations.
Table 2 provides the possible input and output conditions that result
from different input signals and conditions.
