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
