1INTRODUCTION
1.1 Introduction
The EVX 800 line is a range of digital controllers studied to manage temperature-controlled blast chillers, which can be
mechanically and aesthetically integrated into the unit.
The range is made up from 4 devices: EVX802, EVX812, EVX805 and EVX815.
EVX802 and EVX812 have:
- clock (EVX812 only)
- signal buzzer and alarm
- 3 analogue inputs (cabinet probe, needle probe and evaporator probe) for PTC/NTC probes
- 1 digital input (door micro switch)
- 1 input that can be set for analogue input (condenser probe, for PTC / NTC probes)/digital input (high pressure)
- 2 digital outputs (electromechanical relays), 1 x 30 A res. @ 250 VAC for compressor management and 1 x 8 A
res. @ 250 VAC for the management of a second utility (can be set for defrosting or evaporator fan); defrosting
can be electrical, hot gas, air or with air with door open
- serial port with MODBUS communication protocol
EVX805 and EVX815 have:
- clock (EVX815 only)
- signal buzzer and alarm
- 3 analogue inputs (cabinet probe, needle probe and evaporator probe) for PTC/NTC probes
- 1 digital input (door micro switch)
- 1 input that can be set for analogue input (condenser probe, for PTC / NTC probes)/digital input (high pressure)
- 5 digital outputs (electromechanical relays), 1 x 30 A res. @ 250 VAC for compressor management and 4 x 8 A
res. @ 250 VAC for management of defrosting, evaporator fan, of a fourth utility (that can be set for door
resistances or condenser fan) and a fifth utility (can be set for cabinet lights, 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 devices can manage both temperature and time-controlled 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 devices are presented without cover for complete mechanical and aesthetic integration into the blast chiller; the
user interface is made up from a custom 4-digit display (with function icon) and 8 keys (6 in the EVX802 and EVX812
models).
Back panel installation via M3 studs is envisioned.
Via the "HACCP" function (available in the EVX812 and in the EVX815), 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).
EVCO S.p.A. EVX 800 range | Installer manual ver. 1.2 | Code 144X800E124
page 6 of 66
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:
- direct loads connection (except the utility managed by the fifth digital output)
- two-level management of the overheated condenser alarm
- memorisation of the defrosting interval
- management of temperature alarms
- compressor operating hours count
- "keyboard lock" function.
