4.1. Display
Faults and alarms are displayed as follows:
Faults
The
LED (general fault) will flash whenever a fault occurs.
In conjunction with this LED:
The red
LED lights up and remains lit (only for the emergency stop fault).
If a pictogram appears on the LCD screen this represents the fault along with the SOS message.
OR
An SOS message appears flashing with a fault code.
Alarms
Whenever an alarm occurs, the yellow
In conjunction with this LED:
A pictogram appears flashing on the LCD screen to indicate the alarm along with the SOS message.
4.2. Appearance of a fault or an alarm
The appearance of a a fault or an alarm causes the
following screen to be displayed (one or more pictograms
or a fault code along with the SOS message are displayed).
This screen always appears before the screen referred to in
Section 3.1.1
The user can access the following screens by pressing the key
The fault or alarm screen will disappear once the fault or alarm has been removed.
Only one fault is displayed on this screen (the fault which caused the generating set to stop).
If one or more faults have appeared after the first fault, they can only be displayed after the first fault has been reset
(press «Reset» as many times as the number of faults present).
Note: an alarm can appear at the same time as a fault.
12/22
LED (general alarm) lights up flashing.

Пульт управления MICS Nexys
– это контрольно-управляющий модуль, предназначенный для управления дизель-генераторной установкой (ДГУ), как в ручном, так и в автоматическом режимах. Входное напряжение 12В. Пульт построен по модульному принципу и обеспечивает качественную реализацию основных функций для простого и надежного управления ДГУ.
Модуль может быть установлен в следующие консоли управления ДГУ:
— N 2500 с автоматом защиты ≤ 125 A
— N 3500 с автоматом защиты ≤ 250 A
— N 4500 с автоматом защиты ≤ 630 A
ОПИСАНИЕ
MICS Nexys может работать в ручном и автоматическом режимах.
Ручной режим:
запуск и остановка выполняются вручную пользователем.
Автоматический режим:
запуск и остановка выполняются автоматически по внешней команде.
Стандартная конфигурация MICS Nexys.
ОПЦИИ СИСТЕМЫ ЗАЩИТЫ.
В дополнение к стандартной конфигурации, на модуле Nexys могут быть установлены следующие опции:
Плата измерений (для ДГУ мощность 30 кВА и менее):
Подсоединяется непосредственно к главной плате, используется для измерения и отображения:
— Электрических величин
V — напряжение “фаза-нейтраль”,
U — величины напряжений “фаза-фаза”
I — величины фазных токов);
— Аналоговых величин параметров двигателя (давление масла, температура ОЖ и уровень топлива в расходном топливном баке).
Auto.pack (Комплект для автоматического запуска): Состоит из контактора включения подогревателя ОЖ в системе охлаждения двигателя, зарядного устройства аккумуляторной батареи 12 В – 2.5 A, соединяемых с модулем Nexys с помощью жгута проводов; клеммной колодки (2 клеммы) и жгута проводов для внешней команды на запуск ДГУ.
External Starting command (устройство для внешней команды на запуск): 2х-жильный жгут для подключения внешнего устройства к клеммам на консоли управления.
Report pack (Набор контактов удаленной сигнализации): реле с “сухими” контактами для передачи на расстояние следующих сигналов:
Параметры ДГУ стабилизировались и ДГУ готова принять нагрузку;
— Общий аварийный сигнал ДГУ;
— Предупреждающий или аварийный сигнал (в зависимости от конфигурации) о низком уровне топлива.
Speed potentiometer (Потенциометр подстройки частоты вращения двигателя): устанавливается на лицевой панели и служит для регулировки частоты вращения двигателя (только для двигателей, оснащенных электронным регулятором частоты вращения).
Voltage potentiometer (Потенциометр подстройки выходного напряжения): устанавливается на лицевой панели модуля и служит для регулировки переменного напряжения электрогенератора (потенциометр соединяется с регулятором напряжения, который допускает внешнюю установку опорного напряжения).
Horn (Звуковая сигнализация): подключается к выходу «общий аварийный сигнал» и обеспечивает подачу звукового предупреждения в случае поступления какого-либо аварийного сигнала; нажатием кнопки «horn off» подача звукового сигнала (и только его) может быть отменена.
Auxiliary emergency stop button (Выносная кнопка аварийного останова ДГУ)
Power detection (Реле контроля сетевого напряжения (регулируемое по времени и порогу срабатывания) Используется для запуска ДГУ в автоматическом режиме в случае:
— пропадания напряжения сети (по одной или более фазам);
— выхода напряжения сети за пределы допуска (устанавливается время задержки и пределы допуска), а также осуществляет контроль направления вращения фаз.
Differential protection (Дифференциальная защита): может быть реализована:
— или с помощью блока «vigi», непосредственно подключенного к автомату защиты (пределы допуска по току и время срабатывания не регулируются);
— или с помощью реле дифференциальной защиты с регулируемыми пределами допуска и временем срабатывания.
Protection against insulation faults (Контроль сопротивления изоляции) Используется в системах “IT” с изолированной нейтралью и устанавливается путем добавления датчика сопротивления изоляции “PIM” (Permanent Insulation Monitor).
Automatic filling (Топливный насос для автоматического долива топлива) Используется
для автоматического долива топлива в расходном баке. Включает в себя
топливный насос с модулем управления, подключенным.
