Page 43: Parameterization

EK280 Application Manual 6.5.3 Parameterization Parameterization of the EK280 must be effected with the «enSuite» software, as this is the only way of setting all necessary parameters. The parameters to be set will be found under the following menu headings.
Page 44: Continuous Pulse Output

When connecting the outputs to a customer system (e.g. PLC) galvanic separation of both systems is strongly recommended. Especially when using or connecting the EK280 to a hazardous area (hazardous area 1), an external isolation amplifier (permitted for use in hazardous areas) or usage of the FE260 is required.
Page 45: Isolating Outputs (Galvanic Isolation)

EK280 Application Manual In particular, when connecting more than one output to a PLC, it must be taken into consideration that under normal operating conditions all 4 outputs have a common earth. Inputs on a PLC often have a common «plus» contact so that all outputs can be switched in parallel.
Page 46: Securing The Outputs

(galvanic separation) Galvanic separation of the outputs is not relevant with regard to hazardous areas. If using the EK280 in hazardous area 1 then a permitted, external separator is required which is suitable for use in hazardous areas. An electrically isolated output only requires electricity provided that the output is active (switched on).
Page 47: Data Transfer

 Unplug the modem from the power supply to avoid damage to the modem and SIM card. This applies also to an EK280 with power supply which is disconnected from the mains, in case a back-up battery supply is connected!
Page 48
Connect the modem plug back to the power supply. In case of an EK280 with an internal power supply, the mains voltage must not be switched back on again at this point, otherwise damage to the internal power supply and the internal modem may take place.

There are two available time windows, which operate on EK280 battery power only and for versions of the EK280 with power supply there are two more, which operate only on mains voltage. Make the battery power time windows only as long and frequent as absolutely necessary. Each time window reduces the EK280’s battery life.
Page 50
The editable time window is not directly reflected in the forecast of the remaining battery life of the batteries» BatR» of the EK280. Therefore the forecast battery life is not changed if the time window is changed. Past time windows and data transfers are however used in the remaining battery capacity «BatRK»…

* In place of DTR you may use RTS (DB-9: Pin 7, DE-25: Pin 4). The signal must run continuously at positive voltage (high-signal) throughout the data transfer. RI may not be used! In EK280 battery operation the signal is switched off again (voltage ≤ 0 V, low signal), in order to preserve the EK280 battery’s life.

If the conditions for activating the time window connection are satisfied, then the interface is opened and the EK280 is ready to act as a recipient. If a modem is connected to this interface then the EK280 is only ready to act as a recipient after a further 30 seconds.
Page 119: Point-In-Time Connection

A point in time connection can be manually initiated at any time (e.g. for a test). To do so, change the parameter «TestC» to 1 («open»). The EK280 opens the interface and attempts to reach the target. In order to follow the progress of the point in time connection, observe the «StCon» parameter and «SDst 1, 2».

Корректор газа потоковый ЕК280 продолжает линейку корреторов серии ЕК и представляет более широкий функционал по сравнению с корректором ЕК270. Корректор газа потоковый ЕК280 предназначен для приведения рабочего объема газа, прошедшего через счетчик, к стандартным условиям (давление газа — 760 мм. рт.ст., температура газа +20°С) путем вычисления коэффициента сжимаемости газа и коэффициента коррекции с использованием измеренных значений давления, температуры газа и введенных параметров газа.

Подключение дополнительных преобразователей давления и перепада давления, наличие цифровых входы и выходов позволяет организовать на базе ЕК280 систему контроля и управления.

Преобразователи давления и температуры

В отличие от корректора ЕК270 корректор EK280 может быть оснащен до 6 преобразователей давления (2 аналоговых и 4 цифровых) и до 4 преобразователей температуры.

Преобразователи давления используются для изменения абсолютного давления на счетчике (Pa), измерения перепада давления на счетчике и измерения давления еще в одной точке трубопровода, например, перед фильтром.

Преобразователи температуры используются для измерения температуры газа в счетчике и для измерения температуры окружающей среды.

Измеренные и вычисленные данные хранятся в энергонезависимом архиве корректора ЕК280.

Подключение СЧ и ВЧ датчиков и датчиков различного функционала

Наличие высокочастотного входа позволяет подключить к корректору ЕК280 среднечастотный датчик импульсов R300 или высокочастотные датчики импульсов A1K (для RVG) и А1S (для TRZ) и точно вычислять мгновенный расход газа не только при стабильном, но и при импульсном режиме работы оборудования.

Дополнительные НЧ/ВЧ входы позволяют подключить к корректору ЕК280 различные датчики, например датчики загазованности и/или датчики контроля периметра.

Методы вычисления коэффициента сжимаемости

Дополнительно к методам вычисления коэффициента сжимаемости NX19 мод и GERG-91 мод, которые применяются в ЕК270, в корректоре ЕК280 добавлен метод МР113, использующийся для вычисления коэффициента сжимаемости попутного нефтяного газа. Таким образом, корректор ЕК280 может использоваться совместно со счетчиками для учета попутного нефтяного газа.

Независимые интерфейсы RS232/RS485 и встроенный GSM/GPRS модем

Корректор EK280 в дополнение к оптическому и RS232/RS485 интерфейсам может быть оснащён ещё одним RS232/RS485 интерфейсом или встроенным GSM/GPRS модемом с внешней антенной.

В этом случае проводные интерфейсы RS232/RS485 полностью независимы друг от друга и позволяют одновременно передавать данные. Таким образом, и поставщик, и потребитель газа могут иметь одновременный доступ по проводному интерфейсу к корректору EK280.

Модем устанавливается внутри корпуса корректора и использует для питания дополнительный элемент питания. Использование встроенного GSM/GPRS модема позволяет организовать дистанционную передачу данных о потреблении газа на сервер сбора данных в тех местах, где нет возможности подключения дополнительного внешнего питания к корректору ЕК280. В этом случае интерфейсы также полностью независимы друг от друга.

Надежный металлический корпус обеспечивает простоту подключения вторичных устройств и допускает установку корректора на турбинный или ротационный счетчик газа, а так же на стену.

Многоточечный дисплей с крупными символами и подсветкой, в совокупности с семикнопочной клавиатурой, обеспечивают удобный для восприятия интерфейс оператора.

Оптический интерфейс передачи данных, расположенный на лицевой панели, позволяет производить настройку корректора и считывание архивов без коммутации соединительных кабелей. Встроенный в корпус корректора ЕК280 GSM/GPRS модем значительно упрощает процесс дистанционного сбора данных.
