Микропроцессорный модуль управления Megacontrol®

Применение: для оптимизации управления давлением, жокей-насосами, уровнем в емкостях и управления скоростью вращения.

•Megacontrol® – это микропроцессорный модуль управления, который совершенствовался в течение многих лет работы в области производства установок повышения давления.

Megacontrol® имеет широкий диапазон возможностей для программирования и оптимизации управления насосами и насосными системами. Микропроцессор хорошо подходит для управления установками, содержащими до 6 насосов. Модуль программируется при помощи стандартного дисплея. Доступ к программированию может быть ограничен при помощи пароля. Текст и параметры системы постоянно отображаются на жидкокристаллическом дисплее, имеющем 2 строки по 20 символов.

•Установка поставляется в нескольких конфигурациях. Полная документация предоставляется.

Оптимизация регулирования давления

Гибкость программирования Megacontrol® позволяет полностью оптимизировать обычное регулирование давления при помощи предварительной коррекции давления, коррекции требуемого давления и автоматической коррекции времени работы.

Управление жокей-насосами

Установка содержит один или более рабочих насосов, которые обеспечивают подачу необходимого количества воды. Жокей-насос поддерживает требуемое давление и дает необходимое количество воды, пока рабочие насосы не включатся в работу.

Когда последний рабочий насос выключится, жокей-насос вновь вступит в работу для поддержания остаточного расхода воды и будет работать до достижения заданного предельного давления.

Управление уровнем в емкостях для хранения воды

При наличии датчика уровня или манометра в емкости уровень воды в ней может контролироваться при помощи следующих функций:

•сигнал переполнения;

•открытие/закрытие 1-го клапана подачи;

•открытие/закрытие 2-го клапана подачи;

•сигнал о критическом уровне воды;

•сброс защиты от «сухого» хода;

•защита от «сухого» хода и другая сигнализация.

Спецификация оборудования

Система с микропроцессорным управлением используется для установок, содержащих до 6 насосов. Модуль предназначен для установки на панели управления и может быть снабжен интерфейсом RS232 для перепрограммирования и связи с внешними устройствами.

Панель управления исполнения IP54 подключается к модулю при помощи коаксиального кабеля.

Модуль управления отвечает стандарту VOE110 и безопасен при работе при температуре окружающей среды до 50 °С и относительной влажности 20-90 % (без конденсата).

Панель управления снабжена 9 кнопками с уплотнением из фольги. Две кнопки снабжены светодиодами для рабочей и аварийной индикации. Жидкокристаллический дисплей имеет 4 строки по 20 символов.

Возможна установка второго дисплея в другом месте установки при помощи интерфейса P8485. Соединение с компьютером управляющей системы возможно посредством интерфейса RS232. Для реализации этой возможности необходимо наличие протокола обмена.

Измеритель давления должен быть откалиброван в процентах от уровня воды. На дисплее количество открытых клапанов отображается цифрами 0, 1 или 2.

Управление скоростью вращения

Управляемый пребразователем частоты насос поддерживает давление до достижения максимальной скорости, после чего включается следующий насос. Это повторяется до тех пор, пока не включатся все насосы.

При снижении расхода скорость насоса, управляемого преобразователем частоты, снижается. При достижении этим наосом минимальной скорости вращения насосы с постоянной скоростью будут поочередно отключаться.

Установка, управляемая преобразователем частоты, будет постоянно поддерживать заданное значение, пока управляющий сигнал не будет постоянным в течение определенного времени. После этого задание повышается на установленное значение и установка выключается. (При повышенном давлении расширительный бак заполняется для компенсации небольшого расхода в то время, пока установка не работает). Megacontrol® может увеличить или уменьшить задание на установленное значение при включении и выключении насосов для корректировки потерь давления при увеличении расхода.

Установка с преобразователем частоты работает внутри настроенного интервала (гистерезис). При получении сигнала аварии от преобразователя установка переходит на аварийный режим работы, при котором насосы включатся и выключатся при достижении границ петли гистерезиса. Этот режим автоматически оптимизируется модулем Megacontrol®.

Пожарные станции FU3

Применение: в Голландии данные насосные станции применяются для зданий высотой более 50 м. Для зданий подобного типа обычно очень трудно бороться с крупным пожаром. Одной из причин этого является то, что двигатели пожарных машин не могут создать достаточное давление для обеспечения водой всего здания. Следовательно, эти здания оснащаются системой пожарных трубопроводов и пожарными насосными станциями.

Наиболее общим является применение насосов с частотными преобразователями для каждого насоса. Обычная установка (показана на рисунке) состоит из 3 насосов: 2 обеспечивают требуемую производительность, 1 находится в резерве. Трубопровод всегда закрывается посредством клапана с электроприводом, расположенного на напорном трубопроводе, только в случае пожара клапан автоматически открывается.

Производительность/давление

Обычно каждый этаж имеет один пожарный ввод, который должен обеспечить расход – 600 л/мин. В зданиях без спринклерных систем необходимо предусматривать 2 пожарных ввода одновременно. Это означает, что общая производительность должна быть 1200 л/мин (72 м3/ч).

Минимальное давление на каждом пожарном вводе должно составлять 500 кПа (5 бар), но не может быть больше 700 кПа (7 бар). На каждые 7 этажей (около 25 м) насосы должны обеспечивать различное давление, в зависимости от того, на каком этаже пожарная тревога.

Панель управления

Панель управления состоит из следующих позиций:

•микропроцессорное устройство управления;

•сигнальные лампы «насос в работе» для каждого насоса;

•сигнальные лампы «неисправность» для каждого насоса;

•потенциометр для настройки давления насосов вручную;

•кнопки для каждой зоны для включения насосов допущенным персоналом;

•кнопка «стоп» для выключения установки после пожара;

•кнопка для проверки сигнальных ламп;

•таймер для проверочного пуска (5 минут каждые 24 часа);

•главный выключатель;

•пускатели двигателей;

•защитные реле двигателей;

•выходы для защиты от «сухой» работы;

•выходы для клапана на напоре.

Подача воды

Для такого типа установки необходима большая подача воды (72 м3/ч). Хорошим решением является установка большого бака с вместимостью, достаточной для обеспечения работы установки как минимум в течение часа.

Работа установки в случае пожарной тревоги

В случае пожара установка включается допущенным лицом из пожарной бригады. Скорость вращения насосов зависит от того, на каком этаже (в какой зоне) была активирована пожарная система. Эта информация отображается на панели управления. Выбор зоны может быть сделан с помощью соответствующих кнопок. После активации этой кнопки насосы начнут работать. Посредством потенциометра выходное давление может быть скорректировано в пределах 10 %. При включением установки клапан автоматически откроется. После погашения пожара установка должна быть выключена кнопкой «стоп» и вся вода должна быть слита. После этого, установка снова находится в резерве.

Описание типичной установки

Пожарная установка, тип FU3 DPL 45 — …Ex/S DN80 114,3 mm.

Полностью собрана и включает в себя:

•3 насоса DPL, 3 фазн. 400/692 В, 50 Гц, 2850 об/мин;

5.4 Functioning

5.4.1 Standard operation

The Megacontrol is an intelligent control unit for different components of pressurization systems consisting out of a maximum of 6 pumps. The required system pressure is sensed by a pressure sensor on the outlet side of the installation.

When as a result of a decreasing water volume the pressure drops below the pressure set point, a pump will be switched on.

When the required system pressure has been reached, the pumps are switched off one at a time. The minimum run time is optimized constantly, which results in a considerable energy saving.

5.4.2 Custom made settings

The Megacontrol can be programmed through the human machine interface (HMI) operating panel and has been protected against unauthorized use by a password.

Also, the service port provides access to the parameters of the program which can be used to optimize the functionality of the installation, (see: “Parameter list”).

WARNINGFor access to the parameters of the program using the service port, always use the special service port cable!

The special service port cable (Art. nr. 6147117698) can by ordered separately.

5.4.3 Number of operating hours per pump

The current number of operating hours of a pump determines which pump will be switched on or off next. The pump with the fewest operating hours will be switched on first and the pump with the most operating hours will be switched off first. This makes sure that all pumps have an equal number of operating hours, including the backup pump.

5.4.4 Test run

In order to prevent pumps from standing still for a longer period of time, an automatic test run procedure is provided as a standard.

5.4.5 Functioning WSD-Sensor (option)

In combination with the Megacontrol, the WSD can generate a failure message when, during a (adjustable) period of time, insufficient refreshment of the membrane switch vessel occurs.

The failure message is generated when:• Insufficient refreshment occurs;• The membrane of the membrane switch vessel

is defective;• There is no air left in the membrane switch

vessel;• The installation is not set / installed correctly.

5.4.6 Temperature-sensor (option)

When the Megacontrol is fitted with a temperature sensor, it can generate a temperature-dependent failure message.

Type ApplicationsWSD Installations with a maximum of 3

membrane switch vessels.

9.3 Hydro-Unit MCJ

ATTENTIONSee factory settings 3-2-2-1

The Hydro-Unit MCJ is fitted with a jockey pump, especially suited for installations with strongly fluctuating water consumption. The jockey pump is a smaller pump with less capacity but the same pressure as the main pumps of the installation. The jockey pump will be started first. If the water consumption is larger than the capacity of the jockey pump, one or more main pumps will be switched on, whereas the jockey pump is switched off. If the capacity of the main pumps is not sufficient, in case of a large water consumption, the jockey pump will also be switched on. A Hydro-Unit can also be fitted with 2 jockey pumps which are each other’s backups.

9.4 Hydro-Unit MCF

ATTENTIONSee factory settings 3-2-2-1

The Hydro-Unit MCF is equipped with one variable frequency drive. If the Hydro-Unit is rotation-controlled, the required system pressure is sensed by a pressure sensor on the outlet side of the installation. An integrated adjustable PID-controller in the software of the Megacontrol ensures that the system pressure remains constant by successively switching on or off one or more (whether or not) rotation-controlled pumps with delay. A pump is only switched on when 100% or respectively 0% of the speed has been reached.

9.5 Hydro-Unit MCMF

ATTENTIONSee factory settings 3-2-2-1

The Hydro-Unit MCMF is equipped with multiple variable frequency drives. If the Hydro-Unit is rotation-controlled, the required system pressure is sensed by a pressure sensor on the outlet side of the installation. An integrated adjustable PID-controller in the software of the Megacontrol ensures that the system pressure remains constant by successively switching on or off one or more (whether or not) rotation-controlled pumps with delay. A pump is only switched on when 100% or respectively 0% of the speed has been reached.

Микропроцессорный модуль управления Megacontrol 3

  • Megacontrol – это микропроцессорный модуль управления, который разрабатывался и совершенствовался в течение многих лет работы в области производства установок повышения давления. Megacontrol имеет широкий диапазон возможностей для программирования и оптимизации управления насосами и насосными системами. Микропроцессор хорошо подходит для управления установками, содержащими до 6 насосов. Модуль программируется при помощи стандартного дисплея. Доступ к программированию может быть ограничен при помощи пароля. Текст и параметры системы постоянно отображаются на жидкокристаллическом дисплее, имеющем 4 строки по 20 символов.

    Применения:

    • Оптимизация управления давлением
    • Управление жокей-насосами
    • Управление расходом
    • Управление уровнем в емкостях
    • Управление скоростью
 

Установка поставляется в нескольких конфигурациях. Полная документация предоставляется.

Оптимизация регулирования давления

  • Гибкость программирования Megacontrol позволяет полностью оптимизировать обычное регулирование давления при помощи предварительной коррекции давления, коррекции требуемого давления и автоматической коррекции времени работы.

Управление жокей-насосами

  • Установка содержит один или более рабочих насосов, которые обеспечивают подачу необходимого количества воды. Жокей-насос поддерживает требуемое давление и дает необходимое количество воды, пока рабочие насосы не включатся в работу.
    Когда последний рабочий насос выключится, жокей-насос вновь вступит в работу для поддержания остаточного расхода воды, и будет работать до достижения заданного предельного давления.

Регулирование расхода

  • При подключении измерителя давления и индикатора расхода управление насосами может осуществляться по давлению (1-й насос) и расходу (остальные насосы). Контроль расхода используется для включения и выключения насосов. Этот контроль может также использоваться для более точного отслеживания потерь давления. (В предварительно настроенной по расходу системе давление поддерживается на заданном уровне).

Управление уровнем в емкостях для хранения воды

  • При наличии датчика уровня или манометра в емкости уровень воды в ней может контролироваться с использованием следующих функций:
     
  • Сигнал переполнения
  • Открытие/закрытие 1-го клапана подачи
  • Открытие/закрытие 2-го клапана подачи
  • Сигнал о критическом уровне воды
  • Сброс защиты от сухого хода
  • Защита от сухого хода и другая сигнализация

Управление скоростью

  • Управляемый преобразователем частоты насос поддерживает давление до достижения максимальной скорости, после чего включается следующий насос. Это повторяется до тех пор, пока не включатся все насосы. При снижении расхода скорость насоса, управляемого преобразователем частоты, снижается. При достижении этим насосом минимальной скорости вращения насосы с постоянной скоростью будут поочередно отключаться.
    Установка, управляемая преобразователем частоты, будет постоянно поддерживать заданное значение, пока управляющий сигнал не будет постоянным в течение определенного времени. После этого задание повышается на установленное значение, и установка выключается. (При этом повышенном давлении расширительный бак заполняется для компенсации небольшого расхода в то время, пока установка не работает). Megacontrol может увеличить или уменьшить задание на установленное значение при включении и выключении насосов для корректировки потерь давления при увеличении расхода.

    Установка с преобразователем частоты работает внутри настроенного интервала (гистерезис). При получении сигнала аварии от преобразователя установка переходит на аварийный режим работы, при котором насосы включаются и выключаются при достижении границ петли гистерезиса. Этот режим автоматически оптимизируется модулем Megacontrol.

Спецификация оборудования

Система с микропроцессорным управлением используется для установок. содержащих до 6 насосов. Модуль Megacontrol предназначен для установки на панели управления и может быть снабжен интерфейсом RS 232 для перепрограммирования и связи с внешними устройствами.
Панель управления исполнения IP 54 подключается к модулю при помощи коаксиального кабеля. Модуль управления отвечает стандарту VDE 110 и безопасен в работе при окружающей температуре до 50 ° С и относительной влажности 20-90% (без конденсата).

Панель управления снабжена 9 кнопками с уплотнением и фольги. Две кнопки снабжены светодиодами для рабочей и аварийной индикации. Жидкокристаллический дисплей имеет 4 строки по 20 символов.

Возможна установка второго дисплея в другом месте установки при помощи интерфейса RS 485. Соединение с компьютером управляющей системы возможно
