RAPID
ADVANCE
TIMER
Model 753900 is equippedwith a Rapid
Advance
Timer.
This
timerdoes
not haveadial
or knob.There
areactuallytwo timermotors.
Oneis a standard-speed
motor that rotates
the
timer onefull revolution
in 68 minutes,
while
the
other
motorturns
rapidly.
The RapidAdvance
motor
simply
serves
to ad-
vance
the timercams
to a predetermined
star'
ting position.
Thisstarting
position
is
program-
med
through
the
pushbutton
selector
switch
and
various
contacts
inthetimeritself
forany
given
cycleselection.
Thisaction
issimilar to astandard
timer
being
manually
advanced
to aSHORT
CYCLE
bythe
user
forcycleselection.
Thetable
in figure
3 shows
how
the
timerisad-
vancedthrough
the cyclefor any given
cycle
selection.
Once
thetimerhas
advanced
to the
predetermi-
ned
starting
position,
the
electricalcircuit
isbro-
kento the Rapid
Advance
timer
motorby one
of the timer switches
andoneof the selector
switches.
The Rapid
Advance
motorstops
and
the normaltimermotortakes
over
to complete
theselected
cycle.
The timer is mountedbehind
the access
panel
of the
dishwasher.
To gain
access
to the Rapid
Advance
Timer,the
access
panel
mustberemoved.
The timer starts
all cycles,
exceptthe MlNl
WASHandECONOcycle,
atincrement
1
ofthe
timer.
The
POTS& PANS
and
NORMAL
WASHcycle
go
through
allcycles
for a
complete
360 rotati'
on.
The RINSE& HOLDcycle
goes
through
the
first washandrinse cycles
only.TheRINSE
&
HOLD cycle
finishesin increment 14of the
timer.
The RapidAdvance
Motoradvances
the
timer
to the
draincycle
in increment 39.
When
