ELECTRICAL SYSTEM
ELECTRICAL BOX (CONT.)
1. Brew Relays:
Switches high voltage onto the brew tank heating elements.
2. Pump Wire(s):
Carries 220v to the pump motors from the electrical box. Contains 3 wires: black
(110v), white (110v) and green (ground). A fourth wire (Red), is used for bypass system control
when appropriate.
3. Power Wire:
Provides 220v power to machine.
4. Lid Safety Switch
:
Cuts power to the control board and other electronics when the lid is removed.
5. Pump Relays:
Switches high voltage onto the pump motors.
6. Element Breaker:
Disconnects voltage from all heating elements.
7. Electronics Power Switch:
Turns the machine off and on. If the machine is plugged into an electrical source, the
switch will be illuminated when in the “On” position.
8. Conduit Tube:
Protects power and signal lines from abrasion and other damage.
9.
Power Board:
Controls all automated systems throuout the 2nd generation machine. In 1st generation
machines, the controller was in the display, not the power board.
10. Ribbon Cable:
Transfers signals from display board to power board. Volumetrics and shot timers use
additional ribbon cables. 1st generation machines used a ribbon cable to communicate between
power board and display.
11. Level Probe Wires and Connectors:
Connect level probes to power board and ground.
12. Temperature Probe Connections:
Connect temp probes to display board.
13. Steam Tank Element Relays:
Switches high voltage onto the steam tank heating elements.
14.
Heat Sink:
Dissipates heat produced by the element relays. Located on lid.
