1INTRODUCTION
1.1 Introduction
EVXS815 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 look in open frame board and is made up from a custom 4 digit display (with function icons) and
6 touch-keys; installation is envisioned by back panel via M3 studs.
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:
- 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.
