Section 7 - Technical Information
7.1 Water Services
The mains water supply provides water for the boiler.Water enters at the rear of the
machine through a solenoid operated inlet valve operating at 24v DC, which opens or
closes the water supply as required.
1. Hot Water System
1. Water is heated in the boiler to the required temperature by a heating element
rated at 2.4 Kilowatts.The mains voltage required for the element is switched by
a solid state relay, controlled by the vending machine controller via an analogue
signal transmitted by the thermistor probe.
2. The water level inside the boiler is controlled by a water level probe.When the
water drops below the required level, the controller board operates the mains
water inlet valve until the required water level is restored.
3. A series of 24v DC control valves are mounted on the outside of the boiler.These
supply heated water to each of the mixing stations where ingredients are added
to make the drink.
N.B. An illustration showing the parts breakdown for the Heater Tank is included
in Section 12 - page 116.
2. Water Supply
1. Should the inlet valve fail (or mains water supply be disabled), the controller board
will detect a fault after the inlet valve ‘open’ signal has been active for 2 minutes
or the required water level has not been reached.
2. At this point the keypad will be disabled, all
outputs from the controller board (including
the heater element) will be switched off and
the LCD will show the message opposite.
7.2 Ingredient Dispense
1. The ingredients required for making up a drink are contained in ingredient
canisters and are dispensed by means of a motor driven auger located in the base
of each canister.
