ELECTRONIC SYSTEM
1. Brew relays: Control voltage to the brew tank heating elements.
2. Pump wires:
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:
Safety device which cuts power to the control board when the lid is removed.
5. Pump relays:
Controls voltage to the pump motors.
6. Element breaker: Controls voltage to all heating elements in the machine.
7. Electronics power switch:
Turns the machine off and on. If the machine is plugged into an electrical source, the light will be lit red in the “On” position.
8. Conduit Tube: Tube containing power and signal lines to elements, switches and valves.
9. Power board:
Controls heating elements, valves and level/fill system.
10. Ribbon cable: Transfers signals from display board to power board. Volumetrics and shot timers use additional ribbon cables.
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: Controls voltage to steam tank heating elements. Located on lid.
14. Heat sink: Dissipates heat produced by the element relays. Located on lid.
