1 INTRODUCTION
1.1 Introduction
EVFTFT618 is a digital controller studied to manage retarder proofer cabinets/cells, which can be mechanically and
aesthetically integrated into the unit.
The controller is fitted with:
- clock, signal buzzer and alarm
- 4 analogue inputs of which 3 for PTC/NTC probes and 1 for 4-20mA
- 4 digital inputs (door micro switch, compressor circuit breaker, high pressure and low pressure protection)
- 1 PWM analogue output for management of the evaporator fan
- 8 digital outputs (electromechanical relays), 1 x 16 A res. @ 250 VAC for compressor management, 1
x 16 A res. @ 250 VAC for heating element management and 6 x 8 A res. @ 250 VAC for management of the cabinet
light, humidifier, dehumidifier/condenser fan, defrosting, steam generator and pump-down valve/evaporator fan.
- RS-48 serial port with MODBUS communication protocol
- USB port on board.
The controller supplies a complete control for retarder-proofer cabinets or cells for confectionery and bread-making,
through the automatic management of the complete mixture retarder-proofer cycle.
The machine can have 3 different states, defined unmistakeably in the following way through the entire document:
STAND-BY status: the machine is off but powered, it is not possible to perform any selection/cycle start command
ON status: the machine is on but in stand-by for operating cycle selection
RUN status: the machine is on with a cycle in progress
