The
following
is
the
self
test
the
new
microprocessor
will do
at
first
when
the
unit
is
powered
up
and
also
at
the
end
of
the
light
timing
cycle
(4
minutes).
The
light
timing
cycle
of
four
minutes
is
olwoys just
ofter
a motor run
period.
"Symptom" lists
what
the
operator
light
will
signal
if
there
is
a
self
test
failure
and
"Possible
Cause"
lists
what
the
detected
failure
is
that
causes
the
microprocessor
to
signal
the
problem.
It is
assumed
of
the
time
of
~ower
up,
that
there
will
be
only
one

on
(if any}
and
no
