После включения проигрывает контроль как обычно, но вместо картинки установки шприца пишет «Пожалуйста, обратитесь в сервисную службу». И больше никаких кнопок не слушает. В сервисный режим входит. Сервисники сказали, что лекарством служит установка новой даты технического обслуживания, но выход должен быть «плавным», т.е. сначала выйти в начало меню, а уже потом выключать. Пробовал несколько раз (и «плавно» и «резко») — не помогает.

С учетом опасности, сложности газового оборудования производитель дает минимум информации по устранению неполадок силами пользователя с целью нивелирования рисков. Причин появления ошибки sp3 (5p3) котла Аристон несколько, большая часть проблем решается самостоятельно. Статья объясняет, что делать при сбоях агрегата.
Расшифровка
Отрыв пламени – трактовка ошибки sp3 согласно инструкции на котел Аристон. Неполадка распространенная, с ней сталкиваются в процессе эксплуатации оборудования практически все пользователи. Появление кода – не повод сразу же обращаться к сервисному мастеру. Большинство факторов, вызывающих ошибку sp3, не связаны со сложной поломкой котла Аристон, требующей вмешательства профессионала: код убирается самостоятельно.
Причина отрыва, определяемого ЭПУ, в нестабильном функционировании горелки. Датчик фиксирует пропадание (резкое уменьшение значения) тока ионизации при колебаниях язычков пламени и выдает сигнал, на основе которого формируется ошибка sp3. В Аристон чувствительный элемент установлен на керамической сборке вместе с электродами розжига в камере сгорания (в некоторых моделях – отдельно). На практике код неисправности чаще вызывается внешними факторами, невыполнением регламентных работ в полном объеме, качественно. Начинать поиск причины с учетом надежности итальянского котельного оборудования следует именно с этого.
Шаг 1
Нажать кнопку сброса на панели управления.
В котлах Аристон разных моделей, серий обозначается Reset или R. Удержание в течение 5 сек убирает ошибку sp3, если она вызвана сбоем электропитания.
Шаг 2
Оценить состояние датчика ионизации.
Слой пыли, копоти на проволоке (электроде) снижают чувствительность, отсюда ошибка sp3. Почистить, и код неисправности исчезнет. Если в керамике трещина, скол – заменить прибор.
Совет
Убедиться, что расстояние между электродом и металлом горелки 8 мм. В процессе технического обслуживания камеры сгорания, корпуса теплообменника датчик неаккуратным движением сбивается и не реагирует на пламя. Изменение положения вызывает ошибку sp3. Для выравнивания прибора услуги профессионала не требуются.
Внимание: изгибать проволоку датчика нельзя – она хрупкая; только планку, на которой закреплен прибор.
Мнение эксперта
Шаг 3
Проверить параметры сети (U, f).
В инструкции Аристон отмечено, что устойчивая работа котла гарантирована при стабильности напряжения (~230). Отклонение значения на величину свыше ±10% вызывают сбои и ошибки. В частном секторе, в микрорайонах с интенсивной застройкой перекосы фаз, скачки, понижение U – не редкость. При автономном эл/снабжении объекта нужно проверить работу бензогенератора (дизеля), отрегулировать.
Совет
Подключение котла Аристон через ИБП исключает риск появления ошибок по причине нестабильности электропитания. Преимущество блоков перед стабилизаторами существенное, но об этом продавцы последних предпочитают умалчивать.
В составе ИБП, кроме схем выравнивания U и заряда, имеются (или подключаются) аккумуляторы. АКБ обеспечивают функционирование оборудования даже при обрывах на ЛЭП. Для загородных строений – идеальное решение.
Шаг 4
Проверить качество заземления.
Производитель обращает внимание, что нарушение требований ПУЭ в этой части – причина ошибок котла Аристон. Ненадежный контакт, окисление, обрыв – и появится код неисправности.
Шаг 5
Проверить тягу.
Проблемы с дымоходом вызывают ошибку sp3. Чрезмерная скорость протока газов по каналу приводит к отрыву пламени. Если она недостаточная, слышится характерный хлопок (на профессиональном сленге это явление именуется проскоком). В любом случае код неисправности вызван нарушением состава горючей смеси, подающейся к форсункам горелки Аристон.
Дефицит кислорода наблюдается при замусоривании воздуховода. При монтаже двухконтурных газовых котлов устанавливаются коаксиальные дымоходы. Нужно проверить, не заблокирован ли тракт инеем, льдом или мусором, а фильтр – пылью. Устранение подобных факторов убирает ошибку sp3.
Совет.
- Диагностика котлов Аристон атмосферного типа проще. Чтобы убедиться, что ошибка sp3 вызвана недостаточным притоком воздуха в камеру сгорания, нужно распахнуть двери, окна. При положительном результате организовать принудительный приток кислорода в комнату. Если в смежном помещении работает мощное вытяжное устройство, отключить. Оно вызывает сбои котла и ошибку sp3. Производитель Аристон обращает особое внимание на недопустимость эксплуатации подобных технических средств поблизости от отопительного агрегата с естественной тягой.
- Появление ошибки sp3 при пуске котла в эксплуатацию – свидетельство просчетов в проектировании, монтаже дымохода. Его параметры рассчитываются с учетом характеристик агрегата (мощности и ряда иных). Несоответствие сечения канала, протяженности, количества поворотов, уклона требованиям производителя вызывают отрыв пламени, ошибку sp3. Случается при самостоятельном обустройстве системы или подключении купленного котла Аристон к имеющейся в доме.
Шаг 6
Тестирование газового тракта. Ошибка sp3 – результат влияния нескольких факторов.
- Нестабильность, пониженное давление в трубе. Проверить несложно по работе газовой плиты. Разжигаются все конфорки (максимальная потребляемая мощность) и визуально оценивается устойчивость язычков пламени, высота, оттенок. Если они меньше обычного, причина ошибки sp3 в нарушении подачи «голубого топлива» к котлу Аристон. При автономном газоснабжении возможна предельная выработка объема газа в резервуаре (баллонная группа, газгольдер).
- Если ошибка sp3 появилась после очередной заправки емкости, причина – в низком качестве газа. С такой проблемой сталкиваются пользователи, желающие сэкономить. Покупка топлива по привлекательной цене, у малоизвестного поставщика приводит к сбоям в работе котла Аристон.
- Обледенение магистрали и технических устройств. В зимнее время оборачивается падением давления в трубе.
- Неполадки приборов, включенных в газопровод: фильтр, счетчик, редуктор. Невыполнение рекомендаций по регулярному обслуживанию, износ теплоизоляции расположенных вне строения объектов, неисправность – причины ошибки sp3 котла Аристон. Проверить, устранить дефект, и код уберется.
Шаг 7
Оценка состояния горелки котла Аристон.
Отрыв пламени происходит при забивании форсунок пылью. Для приготовления горючей смеси кислорода достаточно, а газа не хватает, отсюда и ошибка sp3. Обслуживание с помощью пылесоса и зубной щеточки, аккуратная чистка, и проблема решается за несколько минут.
Совет
Одновременно необходимо удалить пыль, нагар с нижней части корпуса теплообменного прибора. В процессе функционирования котла Аристон отложения осыпаются, забивая форсунки горелки.
Шаг 8
Диагностика газового клапана. Его некорректная работа – причина ошибки sp3.
Что проверить
- Сигнальные линии. Ненадежные контакты нарушают управление ГК со стороны ЭПУ котла Аристон. Отсюда нестабильная подача газа к горелке и ошибка sp3.
- Настройки. В инструкции котла Аристон имеется соответствующий раздел. Параметры могут быть сбиты по неаккуратности (невнимательности) пользователя или не выставлены нужные значения после замены узла. Проверить, привести в норму, ошибка sp3 уберется.
- Состояние прибора. Он работает, но падение напора газа вызывается забитостью внутренних каналов протока. Все, что необходимо для устранения неисправности – выполнить обслуживание. В инструкции написано, что такая работа выполняется профессионалом. При самостоятельной чистке клапана главное – не сбить заводские регулировки по давлению (max, min), а потому крутить настроечные элементы нельзя. Ошибка sp3 исчезнет после удаления мельчайших фракций, попавших внутрь ГК из системы газоснабжения.
Шаг 9
Тестирование электронной платы.
С ЭПУ на газовый клапан через реле подаются команды управления. Залипания контактов, приводящие к сбоям в работе ГК – одна из причин (но не единственная) ошибки sp3. Самостоятельно ремонтировать плату не стоит, что бы ни советовали пользователи на тематических форумах. Разные модели котлов Аристов, отличия в уровне подготовки, знаний, опыте людей – аргументов против попыток разобраться самому хватает. Все, что требуется сделать – визуальное тестирование.
Осмотром платы выявляются проблемные участки, детали: оплавления, подгорания, окисления, расколы корпусов, отслоения дорожек. Если на ЭПУ пыль, то чистка тампоном нередко убирает ошибку sp3. Ее слой при впитывании влаги становится токопроводящим, что вызывает сбои в работе ЭПУ и коды неисправностей котла Аристон. В статье изложены подробные рекомендации по устранению ошибки sp3 силами пользователя. «Копать глубже», не имея соответствующей подготовки, нецелесообразно. Итальянский отопительный агрегат стоит дорого, и самостоятельное непрофессиональное вмешательство обернется незапланированными финансовыми расходами. Если своими силами не получилось убрать ошибку, обращаться в сервис. При вызове мастера обязательно указать модель, год выпуска котла Аристон и обозначение ЭПУ (цифры и буквы на плате). Узел меняется, а тестирование проводится в условиях стационара, на стенде-имитаторе. Данное решение не оставит дом без обогрева, не повлечет неоправданных денежных трат.

Высокоточный шприцевой насос с автоматическим захватом шприца
ОБЗОР
Aitecs 2016 предназначен для точного и непрерывного дозирования растворов, вводимых с помощью шприцев в различных областях медицины (в палатах общего профиля, отделениях интенсивной терапии и реанимации, отделениях для новорожденных, операционных и отделениях неотложной помощи).
Насос предназначен для инфузии через внутривенные, энтеральные, подкожные или эпидуральные пути введения.
+7 495 649 09 41 / info@viltechmeda.ru
Режимы инфузии
Всего в aitecs 2016 предусмотрено 5 режимов инфузии:
— постоянная скорость (мл/час),
— расчёт скорости по объему и времени,
— расчет скорости по доза и времени,
— прерывистый режим,
— TIVA (общая внутривенная анестезия).
Автоматический захват шприца
При начале работы насоса aitecs 2016 толкатель автоматически подходит к заггруженному шприцу и захватывает его. Такая система сводит к минимуму возможность непреднамеренного болюса при установке шприца и значительно ускоряет начало поступления лекарственного препарата пациенту .
Подключение к системе
aitecs 2016 совместим с нашей системой инфузионного мониторинга (AIMS16), системами управления данными пациента (PDMS) и / или системой клинической информации (CIS) через инфузионную станцию IDS.
Обеспечение безопасности
Насос оснащен дополнительными функциями безопасности: системой быстрого определения окклюзии (ROD).
Для самых маленьких пациентов
aitecs 2016 предназначен для удовлетворения потребностей всех пациентов: от самых маленьких новорожденных до взрослых. Высочайшая точность насоса позволяет проводить инфузия пациентам с весом от 300 грамм.
Для скорой помощи
Насос соответствует требованиям стандарта EN1789 и подходит для использования в автомобилях скорой помощи.
Все под контролем
Используйте aitecs 2016 вместе с волюметрическим насосом 3017 в одной системе с инфузионной станцией IDS.
IDS организует пространство около пациента предотвращая путаницу и повреждения насосов и обеспечивает их общее электропитание.
В качестве коммуникационного устройства IDS передает информацию об инфузия на компьютер с установленной программой мониторинга инфузии AIMS16 или другой клинической информационной системы, системы PDMS.
