The Brio ESE vending machine is fitted with the same actuation
board used on the base model (with a specific Eprom); this board
processes the information from the push-button board, the
payment systems and from the sensors installed throughout the
machine; it also controls the actuations and the display board
It is built on SMT technology.
An additional board was also added for the specific “ESE” version,
located in the same compartment and controlling the “flow-
through” espresso boiler
(see
photo).
Two other boards are installed:
1) The display board, which processes the information from the
CPU board and converts it into readable signals, and the push-
button board.
2) The push-button board that controls the display, the push-
button actuations; it supports the connectors for the payment
systems.
The CPU/actuation board is set by default to achieve a
temperature of 78-82° C in the Instant boiler.
The espresso boiler control board is set to achieve a dispensing
temperature of 78-85° C.
See brewer unit paragraph for any corrections.
