EV3 — это новое поколение цифровых контроллеров EVCO. Стильный дизайн, сенсорные кнопки, функции охлаждение/нагрев, встроенная функция энергосбережения. Модель EV3B23N7 — это контроллер линейки EV3, предназначенный для управления холодильной установкой с вентилируемым испарителем. Оснащён 2 аналоговыми входами для датчиков NTC/PTC (датчик объёма, датчик испарителя/конденсатора), 1 многофункциональным цифровым входом, 3 управляющими реле (16А @ 250 VAC компрессор / 8А @ 250 VAC оттайка, 5А @ вентилятор испартеля). Контроллеры могут быть исполнены с индикацией температуры красного, голубого, зелёного или бело-лунного цвета. Стандартно же позиции поставляются с индикацией температуры красного цвета. Настройку контроллера можно осуществить как при помощи кнопок, так посредством программного обеспечения Parametrs Manager и ключа программирования EV3KEY компании EVCO. Программный продукт позволяет наглядно отобразить на дисплее Вашего PC полный список параметров с описанием их назначения, а также выбрать необходимые значения для записи на контроллер. Ключ EV3KEY можно использовать как сомостоятельное устройство для копирования параметров с одного контроллера на другой. Это позволяет значительно сэкономить время в условиях промышленного производства или серийной сборки типовых изделий.

Panel installation with snap-in brackets.

the thickness of the panel on which the devise is to be
installed must be between 0.8 and 2.0 mm (0.031 and
0.078 in)

make sure that the device work conditions (tempera-
ture of use, humidity, etc.) lie within the limits indi-
cated; see chapter 8

do not install the device near to any heat sources
(heating elements, hot air ducts etc.), equipment con-
taining powerful magnets (large diffusers, etc.), areas
affected by direct sunlight, rain, humidity, excessive
dust, mechanical vibrations or shocks

in compliance with safety standards, the device must
be installed correctly and in a way to protect against
any contact with electric parts; all parts that ensure
protection must be fixed in a way that they cannot be
removed without the use of tools.

Warnings for the electric connection

do not use electric or pneumatic screwdrivers on the
device terminal board

if the device has been taken from a cold to hot place,
humidity could condense inside; wait about 1 hour
before powering it

check that the power supply voltage, mains frequency
and electric power fall within the set limits; see chap-
ter 8

Cut the device power supply off.

Make sure that the manufacturer’s settings are appropriate;
see chapter 9.

WARNING LIGHTS AND DIRECTIONS

Meaning
Compressor LED
If the LED is on, the compressor is on
If the LED is flashing:

the working setpoint is in the process of being
set (via the procedure described in paragraph
4.1)

a compressor protection will be in progress

Defrost LED
If the LED is on, defrost is in progress
If the LED is flashing:

defrost will be requested but a compressor pro-
tection will be in progress

dripping will be in progress

defrost will be requested but a compressor mini-
mum switch-on shall be in progress

Evaporator fan LED
If the LED is on the evaporator fan will be on
If the LED is flashing evaporator fan standstill will be
in progress
Energy saving LED
If the LED is on and the display is switched on, the
“energy saving” function is in progress
If the LED is on and the display is switched off, the
«low consumption» function is in progress; press a
key to restore normal display

Celsius degrees LED
If the LED is on, the unit of measurement for tem-
perature is Celsius degrees

Fahrenheit degrees LED
If the LED is on, the unit of measurement for tem-
perature is Fahrenheit degrees
LED on/stand-by
If the LED is on, the device is switched off

the keyboard is blocked; see paragraph 3.7

the operation requested is not available

Minimum temperature alarm
Solutions:

check the room temperature; see A1 parameter

the device will continue to operate normally

Maximum temperature alarm
Solutions:

check the room temperature; see A4 parameter

the device will continue to operate normally

Door switch input alarm
Solutions:

check the causes of the activation of the input;
see i0 and i1 parameters

the effect established with the i0 parameter

Multifunction input alarm or pressure switch alarm
Solutions:

check the causes of the activation of the input;
see i0 and i1 parameters

the effect established with the i0 parameter

COH Condenser overheated alarm

check the condenser temperature; see C6 pa-
rameter

the device will continue to operate normally

Compressor shut down alarm
Solutions:

check the condenser temperature; see C7 pa-
rameter

switch the device off and back on again: if
when the device is switched back on, the tem-
perature of the condenser is still higher than
that established in C7 parameter, disconnect
the power supply and clean the condenser

the compressor will be switched off

Defrost alarm switched off because maximum time
has been reached
Solutions:

check the integrity of the evaporator probe; see
d2, d3 and d11 parameters

press a key to restore normal display

the device will continue to operate normally

When the cause of the alarm disappears, the device restores
normal operation, except for the following alarms:

compressor shut down alarm (code “CSd”) which re-
quires the switching off of the device or the temporary
suspension of the power supply

defrost alarm switched off because maximum time has
been reached (code “dFd”) which requires the pressing
of a key.

Room temperature probe error
Solutions:

check that the probe is the PTC or NTC type;
see P0 parameter

check the device-probe connection

check room temperature

compressor activity will depend on C4 and C5
parameters

the defrost will not be activated

Evaporator probe or condenser probe error
Solutions:

the same as in the previous example, but with
regard to the evaporator probe or the condenser
probe

if P4 parameter is set at 1, the defrost interval
will last for the amount of time set with d3
parameter

if P4 parameter is set at 1 and d8 parameter is
set at 2 or to 3, the device will operate as if d8
parameter were set at 0

if P4 parameter is set at 1 or 2 and F0 param-
eter is set at 3 to 4, the device will operate as if
parameter were set at 2

if P4 parameter is set at 3, the condenser over-
heated alarm (code “COH”) will never be acti-
vated

if P4 parameter is set at 3, the compressor shut
down alarm (code “CSd”) will never be acti-
vated

When the cause of the error disappears, the device restores
normal operation.
