once again after a few degrees of
rotation the timing cam closes the
holding switch providing a circuit to
the motor that will assure completion
of this revolution. the mold heater
remains energized. the shut-off arm
will raise and lower again operating
its switch. the ice that was ejected
during the first revolution is dumped
into the storage bin.
Sometime during the second revolu-
tion the mold heater resets the ther-
mostat. at this time, the mold heater
is de-energized. If the storage bin is
full, the shut-off arm will remain in a
raised position.
near the completion of the second
revolution the timing cam again
closes the water valve switch. this
time a circuit is completed through
the water valve solenoid, its switch
and mold heater. the water valve
solenoid received about 105 volts.
the remaining 10 volts to the mold
heater are not noticeable. When the
water valve solenoid is energized,
the valve opens and water refills the
mold.
the ejection cycle ends the mo-
ment that the holding switch
is closed by the timing cam.
the water valve switch is also
opened. If the storage bin is full,
as shown here, additional cy-
cles will not start until sufficient
ice is used to lower the shut-off
arm, thus operating its switch.
