Lme22 331c2 ошибки

Здравствуйте!
Добрался до котла.
Повесил вместо датчика пламени резистор на 1.3Ком начал вываливаться сразу в аварию LME горит красным.
Между выводами уф датчика бесконечное сопротивление, попробовал колхозный метод по проверки датчика, зажигаешь зажигалку рядом с лампой и должно появится свечение. Свечения нет. Не знаю даже, рабочий способ или нет.
Еще способ, визуальный, если на электродах имеется фиолетовый налет, значит датчик вышел из строя. Налет действительно есть.
По паспорту для проверки нужен микроамперметр, подойдет ли для этого цифровой мультиметр китайский?
Электролиты есть, а какое-то напряжение нужно подавать на уф-датчик? Или просто замкнуть цепь микроамперметром и параллельно к амперметру подключить конденсатор? И что использовать для засветки датчика?

Допустим датчик не годный, можно ли какой-то более дешевый аналог подобрать, цена на эту стекляшку 32К.
По паспорту наработка датчика 10 000 часов, котлу уже 10 лет))).

Features

Gas Burner Controls LME…

Gas burner controls for the supervision of 1- or 2-stage gas burners of small to medium capacity (typically up to 350 kW), in intermittent operation.

The LME… and this Data Sheet are intended for use by OEMs which integrate the burner controls in their products.

LME… burner controls are used for the startup and supervision of 1- or 2-stage gas burners in intermittent operation. The flame is supervised by an ionization probe or flame detector QRA… with ancillary unit AGQ3… or blue–burning flames with blueflame detectors QRC…

—

In terms of housing dimensions, the LME… are identical with the LGB… and LMG… burner controls (refer to «Type summary»).

Warning notes

Engineering notes

Mounting notes

To avoid injury to persons, damage to property or the environment, the following warning notes should be observed!

Do not to open, interfere with or modify the unit!

• All activities (mounting, installation and service work, etc.) must be performed by qualified staff

• Before making any wiring changes in the connection area of the LME…, completely isolate the burner control from the mains supply (all-polar disconnection)

• Ensure protection against electric shock hazard by providing adequate protection for the burner control’s connection terminals

• Check the connecting lines of the air pressure switch for short-circuits (connection terminals 3, 6 and 11)

• Press the lockout reset button / operation button only manually (applying a force of no more than 10 N) without using any tools or pointed objects

• Fall or shock can adversely affect the safety functions. Such units must not be put into operation, even if they do not exhibit any damage

• Each time work has been carried out (mounting, installation, service work, etc.), check to ensure that wiring is in an orderly state and make the safety checks as described in «Commissioning notes»

• When used in connection with actuators, there is no position feedback signal from the actuator to the burner control

• When used in connection with actuators, the requirements of EN 676 must be observed

• The running times of the actuators must match the burner control’s program. An additional safety check of the burner control together with the actuators is required

• When substituting burner controls type LGB… or LMG… by LME…, the AGQ1… or

AGQ2… ancillary unit must be replaced by the AGQ3…

• Ensure that the relevant national safety regulations are complied with

Installation notes

• Always run the ignition cables separate from the unit and other cables while observing the greatest possible distance

• Do not mix up live and neutral conductors

• Install switches, fuses, earthing, etc., in compliance with local regulations

• The connection diagrams show the burner controls with earthed neutral conductor.

In networks with nonearthed neutral conductor and ionization current supervision, terminal 2 must be connected to the earth conductor via an RC unit (type reference

ARC 4 668 9066 0). It must be made certain that local regulations are complied with (e.g. protection against electric shock hazard) since AC 230 V / 50 Hz mains voltage produces peak leakage currents of 2.7 mA

• Make certain that the maximum permissible current rating of the connection terminals will not be exceeded

• Do not feed external mains voltage to the control outputs of the unit. When testing the devices controlled by the burner control (fuel valves, etc.), the LME… must not be connected

• In the case of burners with no fan motor, an AGK25 must be connected to terminal

3 of the unit, or else the burner cannot reliably be started up

• For safety reasons, feed the neutral conductor to terminal 2. Connect the burner components (fan, ignition transformer and gas valves) to the neutral distributor as shown below in figure 7101a05. The connection between neutral conductor and terminal 2 is prewired in the base

Wiring of neutral conductors!

Electrical connection of flame detectors

It is important to achieve practically disturbance- and loss-free signal transmission:

• Never run detector cables together with other cables

– Line capacitance reduces the magnitude of the flame signal

– Use a separate cable

• Observe the permissible length of the detector cables (refer to «Technical data»)

• The ionization probe is not protected against electric shock hazard

• Locate the high-voltage ignition electrode and the ionization probe such that the ignition spark cannot arc over to the ionization probe (risk of electrical overloads) and that it cannot adversely affect the supervision of ionization

– Must be a minimum of 50 M

Ω between ionization probe and ground

– Soiled detector holders reduce the insulation resistance, thus supporting cree-

page currents

• Earth the burner in compliance with the relevant regulations; earthing the boiler alone does not suffice

Автоматы горения для контроля 1- и 2-ступенчатых газовых горелок или газовых горелок малой и средней мощности, с нагнетателем или без него в повторно-кратковременном режиме работы. LME22.331C2 и это техническое описание предназначены для производителей, которые устанавливают автоматы горения на свое оборудование.

Краткое описание

Автомат горения, без корзины подключения, микропроцессорный, фиксированное время и фазовая программа, двухступенчатая, прерывистая работа с ионизацией и приводом, t1 = 30 с, TSA = 3 с, время работы привода 12 с, AC 120 В, 50 / 60 Гц.

Применение, особенности

LME22.331C2 предназначены для ввода в эксплуатацию и контроля 1- и 2-ступенчатых газовых горелок или газовых горелок в повторно-кратковременном режиме работы. Контроль пламени осуществляется с помощью ионизационного датчика пламени или датчика пламени QRA с дополнительным устройством AGQ3.xA27 для газовых наддувных горелок или при голубом пламени с помощью датчика голубого пламени QRC.

• Обнаружение пониженного напряжения
• Контроль давления воздуха посредством функциональной проверки реле давления воздуха в течение запуска и в процессе работы
• Возможность дистанционной электрической деблокировки
• Многоцветная индикация рабочих сообщений и сообщений о неисправностях
• Ограничение количества повторов 
• Точная последовательность управления благодаря цифровой обработке сигнала
• Контролируемый повторно-кратковременный режим не более чем через 24 часа непрерывной эксплуатации

Рекомендации по установке

• Раскладывайте высоковольтные кабели зажигания отдельно от остальных кабелей и самого устройства при соблюдении максимально возможного расстояния между ними 
• Не перепутайте нейтральные и находящиеся под напряжением провода 
• Переключатели, предохранители и заземление следует устанавливать исходя из требований действующих местных предписаний 
• Опасность повреждения переключающих контактов! Если вследствие перегрузки или короткого замыкания на клеммах сработал внешний входной предохранитель (Si), следует заменить автомат горения LME. 
• На схемах подключения показаны автоматы горения с заземленным нейтральным проводом. В цепях с незаземленным нейтральным проводом и контролем тока ионизации клемма 2 должна быть соединена с заземляющим проводом через модуль RC (модель ARC 4 668 9066 0). Соблюдайте действующие местные предписания (например, о защите от поражения электрическим током), так как при сетевом напряжении сети переменного тока 120 B (50/60 Гц) или 230 В (50/60 Гц) создается пиковый ток утечки 2,7 мА 
• Убедитесь в том, что не превышен максимально допустимый уровень токовой нагрузки, см. Технические данные 
• Не подавайте внешнее сетевое напряжение на управляющие выходы автомата горения. При тестировании приборов, управляемых автоматом горения (топливные клапаны и.т.д.), LME22.331C2 не должен быть подключен 
• Зафиксируйте заземляющую пластину в цоколе AGK11 на нижней стороне с помощью болта с защитой от самоотвинчивания 
• На горелках без двигателя вентилятора AGK25 должен подключаться к клемме 3, в противном случае горелка не сможет тогда надежно запускаться 
• Из соображений безопасности подведите нейтральный провод к клемме 2. Подключите компоненты горелки (вентилятор, трансформатор зажигания и топливные клапаны) к распределителю нейтрального провода, как показано на рисунке. Соединение между распределителем нейтрального провода и клеммой 2 уже заранее предусмотрено в клеммнике

Пояснения

• V… Топливный клапан
• M Двигатель вентилятора
• Z Трансформатор зажигания

Подключение интерфейса OCI400…

• Вставьте интерфейс OCI400… в гнездо деблокирующей кнопки LME22.331C2 Функция диагностики интерфейса работает только без подключения удлинителя деблокирующей кнопки AGK20…
• Подключите интерфейс OCI400… без какого-либо удлинителя к интерфейсу компьютера в соответствии со следующей примерной схемой подключения

Функционирование

Предварительные условия для запуска горелки:

• Автомат горения должен быть деблокирован 
• Все контакты на линии замкнуты, запрос на подачу тепла 
• Нет пониженного напряжения 
• Реле давления воздуха должно находиться в положении покоя 
• Топливный клапан 1 подключен 
• Двигатель вентилятора или AGK25 подключен  
• Датчик пламени затемнен, посторонний свет отсутствует

Пониженное напряжение:

• Защитное отключение произойдет из рабочего положения, если напряжение сети упадет ниже ~75 В (при UN = ~120 В) 
• Повторный запуск при подъеме сетевого напряжения выше ~95 В (при UN = ~120 В) 
• Защитное отключение произойдет из рабочего положения, если напряжение сети упадет ниже ~165 В (при UN = ~230 В) 
• Повторный запуск при подъеме сетевого напряжения выше ~175 В (при UN = ~230 В)
  

Контролируемое прерывание работы:

Не позднее чем через 24 часа непрерывной работы автомат горения инициирует автоматическое регулируемое отключение с последующим повторным запуском.

Программа управления в случае неисправностей:

При нерегулируемом отключении вследствие неисправности, как правило, сразу же (<1 с) отключаются выходы для топливных клапанов, двигателя горелки и устройства зажигания.

Внимание! Приведенные схемы соединений являются только показательными примерами, которые должны проверяться в каждом отдельном случае в зависимости от конкретного применения!

Горелка без вентилятора и без реле давления воздуха

Только для горелок с управлением вентилятором посредством дополнительного контактора с реле давления воздуха

Входы и выходы/внутренняя cхема подключения и ход выполнения программы LME22.331C2

Внимание! Опасность повреждения переключающих контактов! Если вследствие перегрузки или короткого замыкания на клеммах сработал внешний входной предохранитель (Si), следует заменить автомат горения.

Примечание к изделию

Рекомендации по обслуживанию:

Сервисные адаптеры разрешается использовать лишь в течение непродолжительного времени. Использование должно выполняться под контролем квалифицированного персонала.

Срок службы:

Автомат горения имеет расчетный срок службы, который составляет 250 000 циклов запуска горелки, что при обычном режиме нагрева соответствует приблизительно 10 годам работы (начиная с даты изготовления, указанной на заводской табличке).
