Section 3 Dispenser Operation Section 3 Dispenser Operation Method of Operation (All Models) When ice is required, the customer or attendant presses the ice delivery push button switch. This action activates a relay, which is located in the control box enclosure. The relay energizes the dispenser motor. The dispenser motor is direct-coupled to a right angle gearbox. This gearbox drives a toothed positive-displacement belt, the dispensing auger, and the agitating auger.
Dispenser Operation Section 3 Sequence of Operation QFA-290 PUSHBUTTON OPERATED ICE DELIVERY 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.
Section 3 Dispenser Operation QPA-310 PUSH BUTTON OPERATED ICE DELIVERY 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.
Dispenser Operation Section 3 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. Coin Removal The coin mechanism accepts U.S. 25-cent coins only. Tokens are not available for the Q Series dispensers. Depressing the ice delivery push button allows power to flow through the switch to the solid state relay.
