1 INTRODUCTION
1.1 Introduction
EVFTFT818 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
- 6 analogue inputs (cabinet probe, “multipoint” needle probe with up to three sensors, evaporator probe and
condenser probe) for PTC/NTC probes
- 4 digital inputs (door micro switch, high pressure, low pressure and compressor circuit breaker protection)
- 1 PWM analogue output for management of the evaporator fan
- 8 digital outputs (electromechanical relays), 1 x 16 A res. @ 250 VAC for compressor management, 1 x 16 A
res. @ 250 VAC for management of needle probe heating, 6 x 8 A res. @ 250 VAC for management of
defrosting, evaporator fan, condenser fan, door heating elements, of a seventh utility that can be set for the
cabinet light or UV light and an eighth utility that can be configured for pump down valve or alarm output.
- RS-48 serial port with MODBUS communication protocol
- USB port (according to the model).
The device can manage both temperature-controlled and timed and hard and soft blast chilling and storage cycles and
deep freezing and storage cycles, with intensity management via the use of a PWM analogue output and phase cut
speed regulator for EVDFAN1 single phase fans.
Every operating cycle can be preceded by pre-cooling. The temperature-controlled cycles are also preceded by a test
for checking the correct connection of the needle probe, with "multipoint" probes management (up to three sensors).
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 320 x 240 pixel colour TFT graphic display (3.5")
and 11 capacitive touch-keys; installation is envisioned on rear of panel with studs.
The control module is without cover and installation is envisioned on flat surface with spacers.
The "programs" function can be used to memorise some settings in a program and start an operating cycle with the
settings it has memorised.
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.
It is possible to connect the controller to the Parameters Manager set-up software system, to the monitoring and
surveillance system of the RICS plants, to the data recording device and to download the recorded data (via USB)
EVUSBREC01.
Some of them have an USB communication port; through this port it is possible to make the upload and the download
of the configuration parameters and of the programs and make the download of the information relative to the HACCP
alarms.
The following are indicated among the many other features:
- IP65 protection rating of the user interface
- memorisation of the defrosting interval
- management of temperature alarms
- compressor operating hours count
- "keyboard lock" function.

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 " Test for verification of the 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
6.1.1 Foreword 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 " Test for verification of the 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 temperature-
controlled cycles
- the sensors for which the test is not completed successfully are not used successively.

When the cabinet temperature reaches that established with parameter r12, pre-cooling continues and the buzzer is
activated for 2 s.
6.14 Management of the test regarding correct insertion of
the needle probe
If the needle probe is enabled, i.e. the parameter P3 is set at values different to 0; the temperature-controlled cycles
are preceded by a test on two phases for the verification of the correct insertion of the needle probe.
The second phase is only performed if the first is not completed successfully.
The first phase is completed successfully if the "temperature detected by the needle probe - cabinet temperature"
difference is greater than the value established with parameter r17 in at least 3 controls out of 5 (the controls are
performed at 10 s intervals, consider the difference without sign).
The second phase is completed successfully if the "temperature detected by the needle probe - cabinet temperature"
difference is 1°C/1°F higher with respect to the previous control in at least 6 controls out of 8 (the controls are
performed at time intervals corresponding to 1/8 of the time established with parameter r18; consider the difference
without sign).
If the test is completed successfully, the cycle will be started; if the test is not completed successfully, the buzzer will
be activated for 5 s every 10 s and the cycle will be started with timed-control.
To start the temperature-controlled cycle, press the key or the key. After 1 min from the signal that the test has
not been completed successfully without having operated, the cycle is started with time control.
If parameter r17 is set at 0, the test will not be carried out (neither first nor second phase).

parameter C7, parameter C8 will have no effect
(6) defrosting is only enabled during pre-cooling, on start-up of blast chilling and at the start-up of deep freezing
(in these last two cases on condition that parameter d4 is set at 1) and during storage
(7) 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)
(8) 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
(9) the temperature alarms are only enabled during storage
(10) 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
(11) 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
(12) if parameter P5 is set at 0, the condenser fan will function parallel to the compressor
