Machine Operating Voltage
The minimum electrical requirements must be met to ensure
proper operation of machine:
200-240vac
Single Phase: 30amp dedicated circuit
NEMA L6-30 receptacle, a three wire circuit.
(U.S. machines are typically wired for single-phase
operation)
AC Voltage
The following components in the Integra operate on AC
voltage:
Tank Heaters
Group Heater
Transformer
Milk Pump
Water Pump
Grinders
DC Voltage
All remaining components operate on DC voltage. All control
voltage is DC.
Valves
All water and steam valves on the Integra function using a
negative switching circuit. Voltage is always present at the
component. The drives for the valves are located on CPU board.
The CPU provides the ground to close the circuit and energize
the valve.
Diodes
Diodes are used throughout the Integra electrical connections
to control the flow of electricity and eliminate electric noise
from feeding back into the circuitry.
