Technical Manual
4. The light emied 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 transmied light is
detected. If this is the case, the controller will index the cup tubes unl a full stack is
located. A turret locaon micro- switch ensures that the cup tubes stop centrally over
the cup ring.
Note: The turret motor will run unl the next stack is deposited into the cup splier. This
breaks the LED beam and the cup stack micro switch returns to its normally open state. The
motor will run unl it either nds 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 me-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 posioned 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 indicang
the waste bucket/tray is full and the machine is disabled. The machine will remain in
this state unl the waste bucket/tray has been emped.
7.8 CoEx® Brewer (Espresso Machines)
The unique CoEx® combined coee and espresso brewer provides both freshly brewed
coee along with fresh coee 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 inialise operaons indicang its home posion.
Please refer to Secon 8 for full details of the CoEx® brewer and its operaon.
7.9 Oltre Brewer
Machines may be ed with either one or two connuous belt Oltre brewers. The
chamber, base plate, lter belt and outlet elbows are dierent depending on whether you
are vending leaf tea or ground coee.
Two 24V DC 30rpm motors are used on these brewers, one to raise and lower the brewer
chamber the other to advance the lter belt. A cam operated micro switch signals to the
Main Controller whether the chamber is open or closed.
7.9.1 Coee Brewing
1. The coee outlet elbow and baseplate are colour coded yellow and the belt is white
with black stching.
2. The chamber clamps down onto the base plate and lter, water and coee is then
dispensed. Aer the brew me (set in the engineers program) has elapsed a 24V DC
peristalc pump draws the coee liquor through the lter and is pumped to a
whipper chamber where it can be whipped before being delivered into the cup.
