Electronic control system
It consist of several printed circuit cards:
•
Control card
, which governs all of the machine’s movements, as well as
programming of options and product audits, and also power sources that supply
appropriate voltages for logic control, to move the tray motors, to supply peripherals
on bus 485 and to supply the product detection system. The program is recorded in
FLASH memory.
•
Relay card,
which has the relays that control the connection to the compressor,
electrovalve and showcase light. The connection for these systems that work at 220
VAC is synchronised by setting the voltage to zero.
•
Custom display card
, which has the LCD display, the buzzer control and
connections for the product selection pushbutton panel and programming button. It is
a peripheral controlled by the control card with which it communicates using bus 485.
It is possible to adjust the contrast of the messages on the display by turning a
potentiometer.
•
Photodiode and phototransistor cards
of the product detection system.
•
Electronic thermometer card
.
•
Modem communication interface card
.
R 134A CFC-free cooling unit
(Easy Combo)
It is managed by a program which controls the temperature of the machine product hold
electronically.
The machine is equipped with a cooling unit and a turbine to keep a constant working
temperature in the product hold. This temperature, also called cooling unit cut-off
temperature, is programmable (

). When the internal temperature rises
2.5 °C above the cooling unit cut-off temperature, the cooling unit turns on. When the
internal temperature again matches the cut-off temperature, the cooling unit turns off.
