1 System components

1.1 General information

This compact flowmeter complies with the European Directive 94/9/EC (ATEX 100a) and has been approved for hazardous classified locations of Zone 1 and 2 under EC-type Examination Certificate number:

KEMA 01 ATEX 2232 X

The compact flowmeter is available in two types, namely:

• IFM 5080 K/CAP-EEx regular explosion protected version;

• IFM 5080 K/CAP i-EEx, MODIS version. This type has intrinsical safe signal output circuits, which are provided by two MODIS modules that are installed on the IFC090 K/CAP/i-EEx electronics unit.

Temperature classification

The regular IFM 5080 K/CAP-EEx compact flowmeter is designed for ambient temperatures (Ta) of

-20°C (special -40°C) up to +60°C.

The allowed process liquid temperature is a.o. limited by the maximum occuring surface temperature of systems components in the combustible atmosphere that (possibly) surrounds the apparatus (first column of the table). For dusts the second column of the table applies. Details see following table.

Max. surface class (for gases)

T6 T5 T4

The IFM 5080 K/CAP…-EEx compact flowmeter consists of the IFC 090 / CAP/…-EEx signal converter unit, which is screwed on top of the IFS 5000 CAP-EEx primary head (i.e. measuring unit). The regular compact flowmeter is marked with one of the following codes below, depending on the type of protection of the terminal compartment:

II 2 GD EEx d IIC T6…T4 (EEx d terminal compartment) or II 2 GD EEx de IIC T6…T4 (EEx e terminal compartment)

In case of the MODIS version IFM 5080 K/CAP i-EEx, the electronics unit of type IFC 090 / CAPi-EEx is provided with protective modules, which provide intrinsical safe output signals of category "ia". The flowmeter is then marked with the codes:

II 2 GD EEx d [ia] IIC T6…T4 (EEx d terminal compartment) or II 2 GD EEx de [ia] IIC T6…T4 (EEx e terminal compartment)

For details see the EC-type Examination Certificate in instructions.

1.2 IFC 090 / CAP/…-EEx signal converter

The IFC 090 / CAP/…-EEx signal converter consists of a cylindrical housing of die-casted aluminum, which has two separate compartments, divided from each other by an integrated wall with casted flameproof terminal feed-through. The neck at the bottom of the housing contains a flameproof cable feed-through. The signal converter housing is on both ends closed by a cylindrical threaded cover with O-ring sealing. The housing has an ingress protection degree of IP 65 / IP 67 conform to EN 60529.

1.2.1 Electronics compartment

The electronics compartment accommodates the pre-certified IFC 090 / CAP…-EEx electronics unit with approval number PTB 98 ATEX 2012 U. The electronics compartment is designed with type of protection flameproof enclosure "d" according to EN 50018. It is closed by a threaded flameproof display cover with glass window.

1.2.2 Terminal compartment

The terminal compartment has seven terminals for connection of the power supply and signal output circuits. Sect. 2 (Connection diagram) shows the terminal arrangement for the regular and MODIS version of the IFC 090 / CAP/…-EEx signal converter. The terminal arrangement of the MODIS version (i.e. IFC 090 / CAP i-EEx) is shown in Sect. 2 (Modis Converter). Two of the terminals are used for connection of the non-intrinsically safe power supply and four terminals (marked with "*") for the intrinsically safe, category "ia" signal outputs of the MODIS modules. The non-intrinsically and intrinsically safe terminals are separated from each other by a metal dividing plate, which is screwed to the remaining (not connected) M4 terminal. The two non-intrinsically safe power supply terminals are covered by an insulating plate.

The terminal compartment (with standard type of protection increased safety "e") is standard equipped with two ATEX approved "EEx e" cable glands. The terminal compartment can also be provided as a flameproof enclosure "d", in which case ATEX approved "EEx d" cable glands of size Pg13.5, Pg16 or M20x1.5 are either factory installed or must be installed by the customer. For flameproof conduit systems, the terminal compartment must have type of protection flameproof enclosure "d" according to EN 50018. The conduits must be sealed by "EEx d" approved (within the ATEX 100a directive) sealing devices (i.e. stopping box) directly at the conduit entrances of the as flameproof enclosure performed terminal compartment.

2 Electrical connection

2.1 Equipotential bonding system

All EEx and EEx/i flowmeters must always be incorporated into the equipotential bonding system of the hazardous area. This connection can be achieved through the PE/FE conductor connected to the PE terminal in the terminal compartment (see figure of terminal arrangement below) or through a separate PE conductor, cross sectional area at least 4 mm the converter housing.

2.2 Connecting cables

Note

The below described cables are shown in the following connection diagram.

Cable A:

Signal cable for current output and binary outputs (pulse and status output): The cable parameters must be in accordance with the regulations in the EN 60079-14 "Electrical installations in hazardous locations" or an equivalent national standard. For the MODIS version with IFC 090 / CAP i-EEx electronics unit (right detail in connection diagram) the signal cable for the intrinsically safe signal in/outputs must also conform the requirements as specified in the relevant standard national code of practice for the installation of electrical apparatus with type of protection Intrinsic Safety "i".

Cable B:

Power supply cable: The cable parameters must be in accordance with the regulations of the EN 60079-14 "Electrical installations in hazardous locations" or an equivalent national standard.

2.4 Regular IFC 090 / CAP-EEx electronics unit

The field cables that enter the terminal compartment of the IFC 090 / CAP-EEx signal converter unit (i.e. power supply, current and binary outputs) are non-intrinsically safe. To connect external devices to the signal output terminals, the wiring requirements for the type of protection of the compartment (standard: increased safety "e", optional: flameproof "d") must be conform to the international or national standard involved (e.g. EN 60079-14). The terminal arrangement is shown below.
