QCA-330 COIN OPERATED
Inserting a coin into the slot activates a micro
switch on the coin mechanism. Power flows to the
time delay relay, and closes the normally open relay
contacts. The closed contacts supply power to the
push button switch.
Depressing the ice delivery push button allows
power to flow through the switch to the solid state
relay. The relay energizes and powers the windings
of the dispenser motor. This motor drives a
gearbox, which in turn drives a pulley. A toothed
positive displacement v-belt is attached to the drive
pulley, a spring loaded tension pulley, and the
agitator and dispenser pulleys. The turning of the
augers causes the ice to ride to the top of the
dispensing auger, where it will open a door and
drop through the ice chute into the bucket placed
beneath the outlet.
When sufficient ice has been dispensed, the push
button is released, and delivery stops.
The dispenser will not dispense ice until another
coin is inserted.
Time Delay Relay
The time delay relay can be adjusted from 1 second
to 100 seconds. It ships from the factory set to 40
seconds. This setting covers the majority of
applications. Settings of less than 40 seconds can
lead to insufficient quantities of ice being dispensed
if the level of ice in the dispenser is low.
Delivery of ice can be stopped two ways:
1.
The vend push button is released.
2.
The setting on the time delay relay has been
exceeded.
Coin Removal
The coin mechanism accepts U.S. 25-cent coins
only. Tokens are not available for the Q Series
dispensers.
Removal of the front door is not required to access
the coin box.
Insert the key into the cam lock and turn clockwise
to open. The coin door assembly is hinged to swing
downward.
Lift and pull forward on the cash box to remove and
empty.
Re-install the cash box, engage cam lock, and
remove key.
