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.
N.B. An illustration showing the parts breakdown for the Cup Drop Unit is
included in Section 12 - page 151.
7.8 Waste Level Probes
1. The waste level probes, positioned in the waste bucket, detect the water level in
the bucket.
2. The system consists of two probes in a moulded body. 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 is full and the machine is
disabled. The machine will remain in this state until the waste bucket has been
emptied.
7.9 Brewer Unit - (Freshbrew Models)
1. Machines may be fitted with either a single, paper fed type brewer suitable for
providing either freshbrew tea or fresh filter coffee or a dual brewer unit which
provides both freshly brewed tea and filter coffee. The coffee and tea ingredients
are dispensed into the brewer unit via separate canisters.
2. A 24v DC, 3.5 RPM motor, controlled by an index cam fitted to the drive shaft,
operates the brewer unit. The cam operates a switch which sends a logic signal
to the controller when the brewer is in the correct position. The brewer motor
will timeout after 60 secs if the home switch is not seen.
1. Coffee Brewing - Dual Brewer
Technical Manual
1. Water and coffee grounds are dispensed into the brewer top chamber and onto
a filter mesh. The motor drives the piston up and mixes the ingredient and water.
2. The motor drives the piston down and the resulting vacuum pulls filtered coffee
through the filter mesh. As the piston passes the outlet adaptor, coffee flows to
the dispense head. The piston remains in this position for a set time to allow the
vend to drain away.
N.B. There are 4 programmable delay positions which can be set via the
