1IN RODUC ION
1.1 Introduction
The EVXV 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: EVXV802, EVXV812, EVXV805 and EVXV815.
EVXV802 and EVXV812 have:
- clock (EVXV812 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
EVXV805 and EVXV815 have:
- clock (EVXV815 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 ( in the EVXV802 and
EVXV812 models).
Back panel installation via M3 studs is envisioned.
Via the "HACCP" function (available in the EVXV812 and in the EVXV815), 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:
- 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.

5.1 Foreword
The following operating status’ exist:
- the “off” status (the device is not powered)
- the “stand-by” status (the device is powered and is off)
- the “on” status (the device is powered, is on and is in stand-by for the start-up of an operating cycle)
- the “run” status (the device is powered, is on and an operating cycle is in progress).
Hereon, the term "device switch-on" means the passage from the "stand-by" status to the "on" status. The term
"switch-off" means passage from the "on" status to the "stand-by" status.
If a power cut occurs during the "stand-by" status or during the "on" status, the device will re-propose the same
status when the power supply is restored.
If a power cut occurs during the "run" status, the device will operate as follows when the power supply is restored:
- if a temperature-controlled blast chilling or deep freezing operation was in progress, these will be started again
from the beginning
- if a time-controlled blast chilling or deep freezing operation was in progress:
- the EVXV802 and EVXV805 models will be re-started from the time the power cut occurs with a
maximum error of 10 minutes
- the EVXV812 and EVXV815 models will be re-started from the time the power cut occurs
- if storage was in progress, this will be re-proposed.
