The ATEX certificate for the Modular Oven Configuration is Sira 12ATEX1260X and comes with the following conditions for safe use: ● The Maxum II Modular Oven Gas Chromatograph shall be fitted with cable glands or conduit entries having an IP54 minimum rating.
Page 13: Safety Protection Principles

The protection principles used depend on such factors as the type of device, the certifying organization that is applicable for the site, and the type of environment. Table 1-2 details some of the protection principles used in the Maxum II along with the hardware that uses those protection principles.

IS‑TCD and the connections to the CIM touch screen display. Intrinsic safety protection for circuits and devices within the Maxum II enclosure is designed to conform to IEC EN60079-11. This is the standard that is applicable to factory installed electrical components and also for circuits that are additionally protected by other methods, such as a purged Maxum enclosure.
Page 15
● Maintenance for intrinsically safe devices, such as the IS-TCD, is limited to replacement. Repair or service on-site are not permitted. ● Intrinsically safe devices in the Maxum II that are equipped with a cover must have the cover attached during use. Leaving the cover off can violate requirements pertaining to mandatory separation from non-IS wiring.

The primary electronic devices of the Maxum II analyzer are housed inside the electronics enclosure (see Figures 1-1 and 1-2). All electronics in the Maxum II are designed to meet North American Division 2 and European Zone 2 safety requirements. This means that these electronics will not cause combustion of flammable vapors or gases under normal conditions.
Page 18: Electronics Purging System (Without Automatic Purge Unit)

2.2.1 Overview The standard purging system of the Maxum II is controlled by the Power Entry Control Module (PECM) and the processor board (either SYSCON or CIM, depending on the Maxum II configuration). In the standard purging configuration, an alarm is generated whenever purging pressure is lost.

The pressure relief valve, which is shown in the following figure, is located either inside the detector enclosure (middle door or a Maxum II with Airbath/Airless oven) or inside the top left of the electronics enclosure for a Maxum II Modular Oven. The location of the pressure relief valve within the analyzer is shown in Figures 2-1 and 2-2.

4.3.1 Air Treater Functional Description To provide clean air for the Flame Ionization Detector (FID), the Maxum II uses a catalytic device known as an Air Treater (figure 4-8) to remove hydrocarbons from ordinary plant instrument air. The Air Treater is an independent unit mounted near the Maxum II. It consists of an extremely hot combustion chamber and a catalyst.
Page 53: Air Treater Maintenance Considerations

Two versions of the methanator exist for use in the Maxum. The original is protected by purging/ pressurization. The more recent version is protected in an explosion proof enclosure. Both versions are designed to install in the detector enclosure of the Maxum II Airbath/Airless Oven configuration (refer to figure 1-1).
Page 54
When the purged/pressurized version of the methanator is installed, if the purge air supply of the Maxum II is interrupted during operation, it is imperative that the analyzer be powered down. Once powered down, the electronics enclosure door must be kept closed for at least 30 minutes.

Назначение

Хроматографы газовые промышленные Maxum edition II предназначены для измерения содержания компонентов, входящих в состав анализируемых проб веществ и материалов.

Описание

Принцип действия хроматографов основан на разделении компонентов пробы при её прохождении в потоке газа-носителя через хроматографическую колонку и регистрации аналитического сигнала от компонента с помощью детектора.

Хроматографы представляют собой стационарные промышленные приборы и включают в себя электронный блок, один или два термостата с хроматографическими колонками и детекторами, блоки дозирования пробы и контроля газовых потоков, а также системы управления и обработки данных.

Для ввода пробы и переключения потоков между колонками, в зависимости от измерительной задачи, могут использоваться следующие устройства: мембранный кран, поворотный кран с пневмоприводом, пистонный кран жидкостного впрыскивания. В ряде случаев, для распределения потоков между колонками возможно использование бесклапанного переключения по патентованной LIVE технологии.

На передней панели хроматографов имеется сенсорный дисплей, предназначенный для управления прибором и отображения служебной и измерительной информации.

В хроматографах могут быть использованы как насадочные, так и капиллярные колонки.

В зависимости от решаемой аналитической задачи, хроматографы могут быть оснащены одним или несколькими детекторами из следующего списка:

• ДТП -детектор по теплопроводности;

• ПИД -пламенно-ионизационный детектор;

• ПФД- пламенно-фотометрический детектор.

Хроматографы выпускаются в двух исполнениях, которые отличаются габаритными размерами и количеством модулей внутри корпуса. В исполнении 1 в хроматографе могут устанавливаться два типа термостатов: воздушный, термостатирование в котором осуществляется циркулированием горячего воздуха, либо один или два безвоздушных, термостатирование в котором происходит без циркуляции воздуха. В исполнении 2 в хроматограф устанавливаются один или два модуля, каждый из которых представляет собой смонтированный блок из мембранного крана переключения потоков и ввода пробы, хроматографических колонок и термокондуктометрического детектора.

При необходимости установки хроматографа во взрывоопасной зоне, хроматограф может выполняться в специальном взрывозащищенном исполнении с соответствующей маркировкой, указанной в таблице 1. Взрывозащита обеспечивается как продувкой блока электроники хроматографа воздухом КИП под избыточным давлением, так и взрывозащищенным исполнением отдельных узлов и компонентов (детекторов, нагревателей, электромагнитных клапанов и т.п.). Внешний вид хроматографов приведен на рисунках 1 и 2.

2.7 Solid State Relay Module The Solid State Relay (SSR) Module is made up of two pairs of high wattage heater relays that are used for controlling the oven air bath heaters. One pair controls ABH1 and the other ABH2. Each pair of relays controls Temperature Limit and Oven Temperature shut down. If the over temperature limit is exceeded, the power to the air bath heater is shutdown. Two different configurations of SSR are available, the SSR and the

Vapor or High Pres‐ sure Liquid Samples Model 20 The air-pressure actuated, diaphragm valve provides uniform sample volume, low internal volume, high pressure up to 1500 psi, 10350 kPa, fast switching (millisec‐ onds), reliability, and durability. It functions equally well as a liquid or vapor sample valve, column switching valve, or column back flush valve. Liquid Sample LIV The liquid injection valve can be used to automatically inject a constant quantity of liquid sample followed by fast, complete vaporization. Small gas quantities can also be injec
Note Verify proper position of line-voltage selector switch and fuse value. Incorrect settings can damage the equipment.
