Tea Brewing
6. Water and tea are dispensed into the tea brewing chamber.The brewer stays shut
until the required amount of water has passed through the system.When the tea
chamber is empty, the motor operates the wiper arm and the used tea cake is
removed from the tea filter mesh.
7.8 Power Supply Unit
1. The power supply unit (PSU) provides power to the machine.It is mounted on
the floor of the machine and can be accessed by removing the lower front panel.
2. The PSU converts 230v AC to 24v DC to run the valves, whipper motors,
ingredient motors, brewers, etc. fitted to the machine. The solid state relay,
mounted on the PSU chassis, uses a 24v DC switching circuit to provide 230v AC
for the heater element.
3. The Input/Output (I/O) board, mounted on the PSU chassis, utilises signals from
the main controller in order to operate valves, whipper motors, the dispense head
motor, ingredient motors, brewer motors, etc.
4. The PSU houses three fuses.These are as follows.
●
Heater, 12 amp T (ceramic)
●
240v System, 4 amp (glass)
●
240v PSU, 4 amp (glass)
N.B. An illustration showing the parts breakdown for the PSU is included in
Section 12 - page 120.
7.9 16 Amp Filter
A 16 Amp filter, mounted on the rear panel, prevents spurious voltages reaching the
power supply, I/O board, controller boards and other sensitive components within the
machine. It also prevents spurious voltages generated by the machine from reaching the
mains supply.
7.10 Coin Mechanism Transformer
The coin mechanism transformer converts 230v AC to 24v AC for Executive protocol
type coin mechanisms.The 24v AC supply contains an in-line 4 amp, glass fuse.
