i Electronic control system
It consist of several printed circuit cards:
• Control card, which governs all of the machine’s movements, and contains the
power supply that provides the appropriate voltages for the logic control to move the
trays motor, to move the elevator motor to move the motor the verifier of the product
detector and to feed 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.
• Photodiode and phototransistor cards of the product detection system.
• Photodiode and phototransistor cards to control the position of elevator.
• Electronic thermometer card for machines with refrigeration unit.
i R 134A CFC-free cooling unit (Es-Plus)
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 on the master machine. When the internal temperature
rises 2.5 °C (36.5º F) 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.
The cooling unit consists of a compressor and a condenser located in the lower part of
the cabinet, as well as an evaporator located inside the product hold and an axial flow
fan that cools the condenser and the compressor motor. The cooling gas used is the gas
indicated on the machine compressor. The turbine is a fan with two runners located
inside the product hold which is permanently in operation.
