and
HD1B
Indicates
whether the FIC
holds the last
output value or
sets the output
current to zero if
there is loss of
communication
with the
Controller
Processor c ard.
HOLD: The last output value i s
held if there is a failure within
the ControlFile, with the
comm lines, or at the FIC. If
the power supply s hould fail,
the output current goes to
zero.
OFF: The output value is held for
about 1/2 second before
going to zero if there i s a
failure in the FIC processors.
For other types of failures, the
output value is held for up to four
seconds before the output current
goes to zero.
