EV3B22N7

EV3 — это цифровые контроллеры EVCO нового поколения. Стильный дизайн, сенсорные кнопки, функции охлаждение/нагрев, встроенная функция энергосбережения.

Модель EV3B22N7 — это контроллер, предназначенный для управления холодильной установкой со статическим испартелем.

Оснащён 2 аналоговыми входами для датчиков NTC/PTC, 1 универсальным цифровым входом и 2 реле: 16А@250VAC (для управления компрессором) и 8А@250VAC (для управления оттайкой, вентилятором испарителя, освещением камеры или аварийным сигналом тревоги).

По заказу дисплей контроллера может быть исполнен с индикацией температуры красного, голубого, зелёного или бело-лунного цвета. Стандартно же контроллеры поставляются с индикацией температуры красного цвета.

Настройку контроллера можно осуществить как при помощи кнопок, так посредством программного обеспечения Parameters Manager и ключа программирования EV3KEY компании EVCO. Программный продукт позволяет наглядно отобразить на дисплее Вашего ПК 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.

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

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 2, the condenser over-
heated alarm (code “COH”) will never be acti-
vated

if P4 parameter is set at 2, the compressor shut
down alarm (code “CSd”) will never be acti-
vated

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