1.2 Components

Component
Inlet valve KW1 [1001161]
Opens and closes the water supply, 24 Vdc coil closure.
Pressure reducer DR [1000702]
Reduces the water supply pressure to 2 bar.
The water pressure is not adjustable.
Flow meter FL [1000530]
Measures the supplied quantity of water using rotating magnets
and a bi-polar Hall sensor.
Pump KW2 [1000696]
Non-return valve [1000748]
Rotary membrane pump; increases the water supply pressure to
an espresso pressure of 10 bar.
The rotating membrane cells increase the outlet water pressure.
An internal bypass valve pumps the water round in the pump
housing if no pressure decrease occurs.
See Section 5.4 for control / setting.
Pressure boiler H2-3 [1000530]
Closed pressure boiler manufactured entirely from material AISI
316L
Temperature sensor [1000740]
Screw thread M12x1 / material AISI 316L / 100 kΩ/25°C
Boil-dry protection [ 1000736]
Activation temperature 135°C / 2 pole / manual reset

Component
Brewer valve DV1 [1000699]
Supplies the brewer with hot water at 10 bar. When the valve
is energised, the hot water supply to the brewer is opened.
When this closes, the brewer is vented.
Expansion water valve DV6 [1000699]
Pressure relief valve 3 bar [1000734]
This valve is switched as an NO valve. When the coil is not
energised, the supply to the 3 bar pressure relief valve is open.
When coffee is being made, this valve closes off the 3 bar
pressure relief valve so that pump can increase the pressure to 10
bar. After the coffee has been made, this valve opens again and
the excess water pressure is fed to the drainage reservoir.
Mixer valve DV3 [1000699]
Supplies the mixer system with hot water. During the water
measurement, use is made of the 2 bar water pressure that is
reduced by the pressure reducer DR. The valve has an internal
meter of 1.5 mm, which results at a supply pressure of 2 bar in
a measurement speed of 14 ml/sec. When the valve closes, the
mixer supply hose is vented and drains.
Hot water valve DV 4 [1000699]
Supplies the hot water outlet with hot water. During the water
Uitgang
measurement, use is made of the 2 bar water pressure that is
reduced by the pressure reducer DR. The valve has an internal
meter of 1.5 mm, which results at a supply pressure of 2 bar in
a measurement speed of 14 ml/sec. When the valve closes, the
mixer supply hose is vented and drains.
Pressure relief valve 12 bar [1000735]
Over-pressure protection for the boiler.

Coffee grinder [1000665]

The coffee grinder grinds the beans and fi lls the brewer with a
precisely measured quantity of coffee. See Section 1.4 for the
operation.
