Dresser Masoneilan SVI II AP Instruction Manual Multiple Output Circuit Control System ValVue supports HART devices including, the SVI II AP with non-zero polling addresses and supports for multiple SVI II AP on the same loop, for split ranging. To enable this support, check the Multidrop box as shown in Figure 41.

Page 103: Isolators
Wiring an SVI II AP Isolators Isolators Another solution is to use an Intrinsic Safety Isolator for each loop as shown in Figure 42 on page 92. A number of manufacturers make suitable isolators designed for use with HART output circuits. Using an IS Isolator allows up to three SVI II AP to be operated from a single 4 — 20 mA DCS output.

Page 111: Output Channel Isolation
HART Output Channel Isolation Output Channel Isolation The designer of the signaling circuit where the SVI II AP is to be installed must consider the 8 design rules in Wiring Guidelines (see “Wiring Guidelines” on page 80 of this manual). In particular, the control system output interface has analog output channels that are galvanically isolated and share a common ground or are separated from ground by the current control transistor or sense resistor.

Glossary Accuracy In a control valve the position is measured between mechanical motion limits in the valve. These limits can include position variations due to actuator and valve rigidity. therefore, accuracy is referenced to positions within normal travel of the valve independent of rigidity effects at the mechanical limits. Accuracy is the greatest deviation from the expected position within the nor- mal travel, expressed as percent of normal travel. -
Page 152
Dresser Masoneilan SVI II AP Instruction Manual Characteristic The positioner input setpoint command can be selectively modi- fied to provide a desired relationship between setpoint and valve position. In the valve, the relationship between stroke and Cv is also called valve inherent characteristic. It is often adjusted by design, to equal percentage, for example. -

SVI® II AP — это компактный, надежный, высокопроизводительный цифровой позиционер нового поколения с возможностями дистанционной коммуникации и диагностики. Его модульная конструкция облегчает техническое обслуживание. SVI II AP поставляется в различных исполнениях в зависимости от требований эксплуатации. Коммуникация с SVI II AP осуществляется по HART-протоколу. SVI II AP помещен в прочный, герметичный, коррозионностойкий алюминиевый корпус, разработанный для применения в опасных зонах. Электрические присоединения выполняются через два входа с резьбой 1/2″ NPT. Пневматические присоединения выполняются через два/три пневматических порта 1/4″ NPT. Опциональные цифровой дисплей и кнопки предоставляют возможность местного выполнения калибровки и конфигурирования. Дистанционное управление может быть выполнено с компьютера при использовании программы ValVue®, FDT совместимого программного обеспечения, по HART-протоколу с ручного коммуникатора, снабженного файлом-описанием для SVI II AP, или непосредственно из системы управления.

Примеры использования «интеллектуальных» функций
Применение функции Отсечки для защиты седла от эрозии
Вы можете запрограммировать функцию Отсечки для предотвращения эрозии в седле клапана, используя максимальное усилие привода во избежание нежелательной протечки. Например, задание величины этой функции в 2 % приведет к тому, что, при входном сигнале, соответствующем степени открытия менее 2 % привод будет действовать с полным усилием. Это позволяет устранить распространенную причину ремонта клапанов. Не следует использовать функцию Отсечки, если есть необходимость дросселировать через клапан очень маленькие расходы.
Применение функции Отсечки для клапанов сброса жидкости высокого давления
В клапанах сброса жидкости высокого давления функция Отсечки может использоваться для отрыва клапана от седла и начала дросселирования при минимально допустимом значении Cv. Использование функции отсечки в SVI II AP предотвратит повреждение седла, которое может произойти при дросселировании на малых расходах «через зазор».
Непрерывная диагностика
SVI II AP постоянно собирает важную информацию, которая может использоваться для прогнозирования периодов обслуживания регулирующих клапанов. Сюда входят:
— полный ход;
— количество циклов;
— время в открытом и закрытом положениях;
— время в положении, близком к закрытому.
Мониторинг сильфонного уплотнения клапана
SVI II AP автоматически сохраняет суммарное число изменений направления хода как «Количество циклов». Используя ValVue 2, можно периодически запрашивать эту величину и отслеживать оставшийся срок службы сильфона или сальника. Диагностическая информация «Полный ход» может также быть использована для оценки оставшегося срока службы сальников и уплотнений.
Критическое и антикавитационное применение
Время нахождения клапана в положении «близком к закрытому», если он работает при критических параметрах, может сохраняться программой ValVue 2 в постоянном файле и использоваться для отслеживания и прогнозирования необходимости в обслуживании. Пользователь при помощи ValVue 2 может задать критерий для определения времени в положении, «близком к закрытому» (положение клапана, например, 4 %).
Расширенная диагностика
Тест «Стандартной диагностики» выполняет полный ход клапана, определяя время хода. Тест «Шаговой реакции» (Step Response) перемещает клапан между несколькими точками, выбираемыми пользователем и графически представляет динамическую реакцию для каждого шага. Тест «Характеристика позиционера» (Positioner Signature) перемещает клапан на выбранный пользователем ход и сохраняет график для сравнения с заводским и с результатами будущих тестов для прогнозирования интервалов обслуживания. Тест «Расширенна диагностика» (Extended Actuator Signature) медленно изменяет давление в приводе и перемещает клапан в прямом и обратном направление в выбранном пользователем диапазоне. Строит график зависимости хода от давления в приводе, помогает определить трение, и различные неисправности клапана/привода. Для проведения диагностики необходима полная версия ValVue 2.
