4.
The light emitted by the LED is detected when no cups are present. With a stack of
cups present, the beam is broken. As the cups drop below the LED transmitted light is
detected. If this is the case, the controller will index the cup tubes until a full stack is
located. A turret location micro- switch ensures that the cup tubes stop centrally over
the cup ring.
Note: The turret motor will run until the next stack is deposited into the cup splitter. This
breaks the LED beam and the cup stack micro switch returns to its normally open state. The
motor will run until it either finds the next stack or all the turret extrusions have been
checked. If no cups are present the "Out of Cups Please Insert Mug" message is displayed
on the LCD.
5.
The cup stack index motor is protected by a time-out feature. The motor will rotate
for a maximum period of 60 seconds. If at the end of this period no cups have been
detected the LCD will display the "Out of Cups" message.
7.7 Waste Level Probes
1.
The waste level probes are positioned in the waste bucket and detect the water level
in the bucket/tray.
2.
The system consists of two probes. When the water level is high enough that both of
the probes are immersed in the water a message is displayed on the LCD indicating
the waste bucket/tray is full and the machine is disabled. The machine will remain in
this state until the waste bucket/tray has been emptied.
7.8 CoEx® Brewer (Espresso Machines)
The unique CoEx® combined coffee and espresso brewer provides both freshly brewed
coffee along with fresh coffee from beans through the same unit. The unit is driven by a
24V DC 11 RPM motor monitored by a micro switch. The switch sends logic signals to the
controller during vend and initialise operations indicating its home position.
Please refer to Section 8 for full details of the CoEx® brewer and its operation.
7.9 Oltre Brewer
Machines may be fitted with either one or two continuous belt Oltre brewers. The
chamber, base plate, filter belt and outlet elbows are different depending on whether you
are vending leaf tea or ground coffee.
Two 24V DC 30rpm motors are used on these brewers, one to raise and lower the brewer
chamber the other to advance the filter belt. A cam operated micro switch signals to the
Main Controller whether the chamber is open or closed.
7.9.1 Coffee Brewing
1.
The coffee outlet elbow and baseplate are colour coded yellow and the belt is white
with black stitching.
2.
The chamber clamps down onto the base plate and filter, water and coffee is then
dispensed. After the brew time (set in the engineers program) has elapsed a 24V DC
peristaltic pump draws the coffee liquor through the filter and is pumped to a
whipper chamber where it can be whipped before being delivered into the cup.
