1 INTRODUCTION

1.1 Introduction

EVF815 is a digital controller studied to manage temperature-controlled blast chillers, which can be mechanically and

aesthetically integrated into the unit.

The controller is fitted with:

- clock

- signal buzzer and alarm

- 3 analogue inputs (cabinet probe, needle probe and evaporator probe) for PTC/NTC probes

- 2 digital inputs (door micro switch and high pressure)

- 5 digital outputs (electromechanical relays), 1 x 30 A res. @ 250 VAC for compressor management, 2 x 16 A

res. @ 250 VAC for management or defrosting and a utility set for door heating elements or the condenser fan,

2 x 8 A res. @ 250 VAC for management of the evaporator fan and a fifth utility that can be set for the cabinet

light, needle probe heating or UV light; defrosting can be electric, hot air, air or air with door open

- serial port with MODBUS communication protocol.

The device can manage both temperature and timed blast chilling and storage cycles and deep freezing and storage

cycles and also the hard and soft types.

Every operating cycle can be preceded by pre-cooling; the temperature-controlled cycles are also preceded by a two-

stage test for verification of the correct insertion of the needle probe.

The device is available in “split” execution (user interface + control module).

The user interface is behind a Plexiglas sheet and is made up from a custom 4 digit display (with function icons) and 6

capacitive touch-keys; installation is envisioned on rear of panel with biadhesive tape.

The control module is without cover and installation is envisioned on flat surface with spacers.

Via the "HACCP" function, up to 9 events can be memorised for each of the 3 HACCP alarms (temperature-controlled

blast chilling or deep freezing not concluded within the maximum duration alarm, maximum temperature during

storage alarm and power cut during storage alarm); the critical value, date and time at which the alarm occurred and

the duration can be memorised for each HACCP alarm.

The configuration parameters can be uploaded and downloaded using the EVKEY programming key (to be ordered

separately).

Via a serial interface (to be ordered separately), it is also possible to connect the controller to the Parameters Manager

set-up software system, to the monitoring and surveillance system of the RICS plants or to the data recording device,

to download the recorded data (via USB), to upload and download EVUSBREC01 configuration parameters.

The following are indicated among the many other features:

- IP65 protection rating of the user interface

- direct loads connection (except the utility managed by the fifth digital output)

- management of three types of backlight

- memorisation of the defrosting interval

- management of temperature alarms

- compressor operating hours count

- "keyboard lock" function.

Notes:

(1) the unit of measurement depends on parameter P2

(2) appropriately set the parameters relative to the regulators after modification of parameter P2

(3) the time established with the parameter is counted also during the "on" status and during the "stand-by" status

(4) The parameter differential is 2 °C/4 °F

(5) defrosting is only enabled during storage, except for defrosting on blast chilling start and deep freezing start,

which can be established using parameter d4

(6) the device memorises the defrosting interval count every 30 minutes; the modification of parameter d0 has

effect from the conclusion of the previous defrosting interval (or the activation of defrosting in manual mode)

(7) if on activation of defrosting, the previous compressor switched on at from a time shorter than that established

with parameter d15, the compressor will remain on longer for the fraction of time necessary to complete this

time period

(8) the temperature alarms are only enabled during storage

(9) during defrosting. pre-dripping, dripping and evaporator fan standstill, the temperature alarms are not enabled,

on condition that they occurred after activation of defrosting. When the door is open, i.e. if the door micro

switch input is active and the parameter i0 is set at values different to 0, the maximum temperature alarm is

not enabled, on condition that occurred after the door was opened

(10) if parameter P4 is set at 0, during pre-cooling, blast chilling and deep freezing the evaporator fan will be on and

during storing the device will operate as if parameter F2 it were set at 2

(11) the condenser fan operates parallel to the compressor

(12) the door open is enabled only using the "run" state

(13) if the door is opened during defrosting or evaporator fan standstill, opening has no effect on the compressor

(14) modify the parameter during the "stand-by" status to prevent damage to the utility

(15) if parameter u2 is set at 0, device switch-off will cause the cabinet light to switch off and on successive switch

on the cabinet light will remain off. If parameter u2 is set at 1, device switch-off will not cause the cabinet light

to switch off and on successive switch-on the cabinet light stays on.
