1 INTRODUCTION
1.1 Introduction
EVF818 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 30 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.
- TTL type serial port
- RS-48 serial port with MODBUS communication protocol.
The device can manage both temperature-controlled and time-controlled 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 custom 3 + 4 + 1 digit display (with function
icons) and 10 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.
The configuration parameters can be uploaded and downloaded using the EVKEY programming key (to be ordered
separately).
It is also finally 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 or to the print module PM 100A X9S001.
The following are indicated among the many other features:
- IP65 protection rating of the user interface
- management of three types of backlight
- memorisation of the defrosting interval
- management of temperature alarms
- compressor operating hours count, "keyboard block" 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.

6.12 Blast chilling/deep freezing intensity
The device can manage the phase cut speed regulator for EVDFAN1 single phase fans (to be ordered separately); see
paragraph 14.4 “phase cut speed regulator for EVDFAN1 single phase fans”.
The regulator can be used to manage evaporator fan activities with a single analogue control, i.e. via the PWM
analogue output of the device and the regulator phase cut output (the digital output K3 is however activated).
Parameter F0 must be set at 3.
Parameters F18... F22 establish speed 1... 5 of the evaporator speed (intended as a percentage of the maximum
speed), parameter F23 establishes the speed at which the evaporator fan is switched on during post blast chilling
storage and parameter F24 establishes the speed at which the evaporator fan is switched on during post deep freezing
storage (the latter intended as one of the speeds 1... 5).

6.13 Pre-cooling start-up
Every operating cycle can be preceded by pre-cooling.
Operate as indicated to start pre-cooling:
1. Make sure the device is in the "on" status.
2. Make sure no procedures are in progress
3. Hold the BLAST CHILLING key down for 2 s: the LED will flash.
Operate as indicated to cut-off pre-cooling:
4. Hold the BLAST CHILLING key for 2 s or start an operating cycle.
Parameter r120 establishes the work set-point during pre-cooling.
When the cabinet temperature reaches that established with parameter r12, pre-cooling continues, the LED remains
on permanently 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 LED
will flash and the buzzer will be activated for 5 s every 60 s.
To start the temperature-controlled cycle, press the BLAST CHILLING key or the DEEP FREEZING 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).
6.15 Switching on UV light for sterilisation cycle
Operate as follows:
1. Make sure that parameter u11 is set at 2.
2. Make sure the device is in the "on" status and that the door is closed, i.e. the door micro switch is not active.
3. Make sure that the keyboard is not locked and that no procedure is in progress.
4. Hold the DEEP FREEZING key down for 2 s: the AUX LED will switch on.
The UV light is switched on for the time period established by parameter u6; opening the door i.e. the activation of the
door micro switch cause the light to switch off.
If the UV light is on, it will not be allowed to select or start any operating cycle.
6.16 Needle probe heating
Operate as follows:
page 32 of 76
EVCO S.p.A. EVF818 | Installer manual ver. 1.0 | Code 144F818E104

micro switch is active.
2. Make sure that the keyboard is not locked and that no procedure is in progress.
3. Hold the BLAST CHILLING INTENSITY key down for 2 s: the
Output K6 is activated at maximum for the time established with parameter u8 or until the temperature detected by
the needle probe reaches that established with parameter u7; closing the door, i.e. the deactivation of the door micro
switch input causes heating to be cut-off.
The buzzer is activated for 2 s on conclusion of heating.
LED flashes and the AUX LED will switch on.
6.17 Data print-out
The device can manage the PM 100A X9S001 module (to be ordered separately); see paragraph 14.5 "Print module PM
100A X9S001”.
Using the module, it is possible to print information relative to the cabinet temperature, the temperature detected by
the needle probe, at the alarms and at the errors (the latter two on condition that the alarm and/or the error is in
progress on expiry of the print interval.
Parameter L0 must be set at 1.
Parameter L1 establishes the print interval during blast chilling and during deep freezing and parameter L2 establishes
the print interval during storage.
The module prints the data as indicated:
