Ввод значений и выбор вариантов установки параметров

Для изменения цифры в позиции редактирования используйте клавиши со стрелка­ ми вверх m

и вниз

.

. Эти же клавиши используются для выбора вариантов установ­ ки параметров.

Примечание.

  На некоторых страницах меню в одном и том же поле ввода необходимо установить значения нескольких параметров (например, при конфигурировании нескольких точек установки). В таких случаях после установки значения параметра следует вернуться в основное поле ввода с помощью клавиши со стрелкой вправо c

или влево b

и выбрать следующий параметр с помощью клавиши со стрелкой вверх страницу. m

Диалоговое окно Save changes позволяет выбрать один из трех вариантов сохране­ ния:

– Yes & Exit (Да с выходом):

Сохраняет изменения и переходит в режим измерения.

– Yes & u (Да с возвратом на предыдущий уровень):

Сохраняет изменения и возвращается на предыдущий уровень меню.

– No & Exit (Нет с выходом):

Не сохраняет изменения и переходит в режим измерения.

Вариант Yes & u позволяет продолжить редактирование параметров без необходи­ мости повторного вызова меню.

Выберите критерий параметра:

Выбор параметра зависит от уровня трансмиттера. Если выбран датчик ISM, зна­ чение ”Auto” будет означать, что будут распознаваться и приниматься все возмож­ ные датчики ISM. Если выбран специальный параметр, распознаваться и прини­ маться трансмиттером будет только этот параметр.

[ENTER]. Для того чтобы отказаться от настройки параметров аналоговых выходов, выберите No.

Параметры Aout1 min и Aout1 max определяют минимальное и максимальное зна­ чения измеряемой величины, соответствующие границам шкалы выходного тока 4 и 20 мА.

– Between (внутри границ, необходимо задать значения параметров High и Low)

– Outside (вне границ, необходимо задать значения параметров High и Low)

После установки значения уставки (уставок) можно настроить реле (Relay) сигна­ лизации для этой уставки (возможные варианты: none – реле не используется, 1, 2,

3, 4). Для задержки срабатывания реле и гистерезиса по умолчанию установлены значения 10 сек и 5% соответственно. Если  реле настроено как реле CLEAN (реле очистки), оно не доступно из этого меню.

При выборе компенсации ”Внешняя” необходимо установить соответствие меж­ ду минимальным (4 мА) и максимальным (20 мА) выходным сигналом датчика давления и соответствующим аналоговым входом TDL. Введите минимальное и максимальное значения давления в следующих единицах измерения:

– гПа

– psi

– мм. рт. ст.

– кПа

– мбар

Как правило, МЕТТЛЕР ТОЛЕДО рекомендует использовать датчики абсолютного давления для более точной компенсации сигнала в широком диапазоне давле­ ния. Однако, если ожидаются лишь небольшие колебания в районе атмосфер­ ного давления, датчики относительного давления будут давать более качествен­ ные результаты. Но в этом случае не будут учитываться изменения базового барометрического давления.

Для датчиков относительного давления минимальное и максимальное значение необходимо сопоставить так, чтобы TDL мог интерпретировать аналоговый сиг­ нал давления как ”абсолютный”, т. е. к отображаемым значениям необходимо добавить фиксированное барометрическое давление, например 1013 мбар.

При выборе компенсации ”Фиксированная”, значение фиксированного давле­ ния, с которым будет рассчитываться измерительный сигнал, необходимо вво­ дить вручную. Для фиксированного давления можно использовать следующие единицы измерения:

– гПа

– psi

– мм. рт. ст.

Наконец, выберите начальную длину оптического пути, соответствующую длине установленного датчика:

– датчик 290 мм: 200 мм

– датчик 390 мм: 400 мм

– датчик 590 мм: 800 мм

Это начальное значение действительно при продувке прибора со стороны из­ мерительного устройства и со стороны технологической среды. В зависимости от условий технологического процесса, а также после определения оптимально­ го расхода продувочного газа со стороны технологической среды (см. следую­ щий раздел), может потребоваться небольшая коррекция этого значения.

Настройка правильной продувки со стороны технологической среды

Расход продувочного газа будет влиять на эффективную длину пути и, следовательно, на результат измерения.

Для того чтобы настроить правильную продувку, необходимо действовать следующим образом. Начните с очень большого расхода и постепенно умень­ шайте его. Показания сначала будут маленькими, а затем будут увеличиваться по мере уменьшения расхода продувочного газа. В некоторой точке показания выйдут на определенный уровень и будут некоторое время оставаться неизменными, а затем вновь начнут увеличиваться. Выберите расход продувоч­ ного газа в середине области с постоянными показаниями.

2 Показание концентрации при оптимизированном расходе продувочного газа. Длина пути равна эффективной длине пути, так как продувочные трубки полностью заполнены продувочным газом. См. рисунок ниже.

3 Показание концентрации при отсутствии расхода продувочного газа. Длина пути равна номинальной длине пути, поскольку датчик полностью заполнен газом технологического процесса.

4 Оптимизированный расход продувочного газа.

ВНИМАНИЕ!

 Перед началом процесса всегда начинайте продувку с максималь­ ным расходом.

ВНИМАНИЕ!

 Для предотвращения оседания пыли на оптические поверхности продувка должна быть всегда включена.

  Transmitter M400 IP is the isothermal point value (Default = 7.000 for most applications). For specific compensa- tion requirements or non standard inner buffer value, this value can be changed. Adjust the value of the parameter STC pH/°C. STC is the solution temperature coefficient in units of pH / °C referenced to the defined tempera- ture. (Default = 0.000 pH/°C for most applications). For pure waters, a setting of – 0.016 pH / °C should be used. For low conductivity power plant samples near 9 pH, a setting of – 0.033 pH / °C should be used. If the value for STC is ≠ 0.000 pH/°C an additional input field for the reference temperature will be displayed. The value for pH Ref Temperature indicates to which temperature the solution temperature com- pensation is referenced. The displayed value and the output signal is referenced to this tempera- ture.

• Page 10: Safety Instructions

  The following is a list of general safety instructions and warnings. Failure to adhere to these in- structions can result in damage to the equipment and / or personal injury to the operator. – The M400 Transmitter should be installed and operated only by personnel familiar with the transmitter and who are qualified for such work. – The M400 Transmitter must only be operated under the specified operating conditions (see chapter “14 Specifications“ on page 114).

• Page 11: Correct Disposal Of The Unit

  Transmitter M400 NOTE: RELAY CONTROL ACTION the M400 Transmitter relays will always de-energize on loss of power, equivalent to nor- mal state, regardless of relay state setting for powered operation. Configure any control system using these relays with fail-safe logic accordingly. NOTE: PROCESS UPSETS Because process and safety conditions may depend on consistent operation of this trans- mitter, provide appropriate means to maintain operation during sensor cleaning, replace- ment, or sensor or instrument calibration.
