1INTRODUCTION
1.1Introduction
VCOLOR 818 is a controller with elegant design for the management of “top-class” blast chillers.
It is available in split version and can be integrated both mechanically and aesthetically in the unit; the user interface consists of a colour touch-screen TFT graphic display and guarantees an IP65 protection rating, for easy cleaning.
The controller is able to manage positive and negative blast chilling cycles (with intensity management), both temperature and time controlled (with “hard/soft” function); the temperature controlled cycles can be preceded by a test to verify the proper insertion of the needle probe (with management of “multipoint” probes).
It also has the real time clock (to store the HACCP alarms), the “programs” function (to store the blast chilling settings in a program to be selected and run later on) and a USB communication port (to allow the upload and the download of the settings and the data recorded by the controller, through a common USB flash drive).
Installation is by back-panel, with threaded studs (in this case it guarantees no thickness) or by panel (from the front), with self-threading screws and frame (in this case it needs less depth).

5USER INTERFACE
5.1Foreword
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 this 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 timed-controlled blast chilling or deep freezing operation was in progress, these will be started again from the moment the power supply was cut-off
-if storage was in progress, this will be re-proposed.
5.2Device commissioning
Operate as follows:

6.1Foreword
The device can manage the following operating cycles:
-temperature-controlled blast chilling and storage
-temperature-controlled hard blast chilling and storage
-time-controlled blast chilling and storage
-time-controlled hard blast chilling and storage
-continuous blast chilling
-temperature-controlled deep freezing and storage
-temperature-controlled soft deep freezing and storage
-time-controlled deep freezing and storage
-time-controlled soft deep freezing and storage
-continuous deep freezing
For further information, see the next paragraphs
Every operating cycle can be preceded by pre-cooling; see paragraph 6.13 "Pre-cooling start-up".
The temperature-controlled cycles are preceded by a test to verify the correct insertion of the needle probe; see paragraph 6.14 " Management of the test regarding correct insertion of the needle probe".
If the needle probe is not enabled, i.e. if parameter P3 is set at 0, the temperature-controlled cycles will be started with time-control.
The following functions can also be used:
-switching on sterilisation cycle UV light
-heating the needle probe.
For further information, see the next paragraphs
6.1.1Foreword regarding needle probe
The device can manage "multipoint" needle probes (with up to three sensors".
Parameter P3 establishes the number of needle probe sensors as indicated:
-if parameter P3 is set at 0, the needle probe will not be enabled
-if parameter P3 is set at 1, there will be one sensor (needle probe 1)
-if parameter P3 is set at 2, there will be 2 sensors (needle probe 1 and needle probe 2)
-if parameter P3 is set at 3, there will be 3 sensors (needle probe 1 and needle probe 2 and needle probe 3).
If parameter P3 is set at values different to 0, the temperature-controlled cycles will be preceded by a test to verify the correct insertion of the needle probe; see paragraph 6.14 " Management of the test regarding correct insertion of the needle probe".
On conclusion of the test, the device will operate as indicated:
-the sensor that has detected the lowest temperature is then used as the reference temperature for heating the needle probe.
-the sensor that has detected the highest temperature is then used as the reference for the temperaturecontrolled cycles
-the sensors for which the test is not completed successfully are not used successively.
