The IFC 090 F/...-EEx has the following EC-type examination Certificate number: KEMA 01 ATEX 2234 The signal converter is available in two types, namely: IFC 090 F-EEx regular explosion protected version; IFC 090 F/i-EEx, MODIS version.This type has intrinsically safe signal output circuits, which are pro-vided by two installed MODIS modules(see Sect. 1.5 for details). The regular IFC 090 F-EEx signal converter is designed for ambient temperatures in the range of —40°C up to+60°C,the so-called MODIS version type IFC 090 F/i-EEx is rated for ambient temperatures from-20°C up to+60°C. Both types of signal converters are in remote design,which means that they are installed on a certain distance of the measuring unit,the IFS x000 F-EEx series of primary heads. The primary heads are approved according to the European Directive 94/9/EC (ATEX 100a)as well. Due to the installation on a distance from the primary head,the signal converter is independent of the process liquid temperature and therefore rated for temperature class T6 and a T850C for dusts. The IFC 090 F/ ... EEx signal converter is marked with the following code below: Regular version II 2GD EEx de [ib] IIC T6 MODIS version II 2GD EEx de [ia] [ib] IIC T6 Also see the EC-type Examination Certificate in Sect. 8 of these instructions. 1.2 IFS x000 F-EEx primary head The IFS x000 F-EEx series primary head is the measuring unit of the IFC 090 F/...-EEx signal converter and contains two field coils and two electrodes in type of protection intrinsic safety category"ib"according to EN 50020.The type of protection of the field coils depends on the meter type and size, see the additional installation and operating instructions of the primary head concerned. The electrode circuits are wired by separate shielded cables and marked by the sheath color (white and purple).The intrinsical safe"ib"electrode circuits inside the IFS x000 F-EEx primary head have the following maximum values(entity parameters): Maximum input voltage Umax =20 V Maximum output current Imax = 170 mA Maximum internal capacitance C; = 0 Maximum internal inductance L; = 0 The two field coils inside the primary head are connected in series and provided with the type of protection increased safety"e"conform to EN 50019 and additionally flameproof enclosure"d" in accordance with EN 50018 or encapsulation"m"according to EN 50028.The coils have a maximum resistance below 90 Q per coil with a wire diameter of at least 0.25 mm and insulation class H (Tmax>_ 180°C)according to IEC 85.The field coils are supplied with a square-wave signal with a peak voltage of 60 V maximum and a nominal current of 125 mA. The coil circuit is protected by two series fuses in the IFC 090 ...-EEx electronics unit.The fuses are rated for a maximum voltage of 250 Vac @ 50-60 Hz, have a breaking capacity of at least 35 A and switching characteristics fast(F)to time-lag (T).

It 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 that is connected to the wall-mounting bracket with junction box, contains flameproof cable feed-through type LC-2/EEx,which is approved by KEMA under No. Ex-01.E.2036 U.The wall-mounting bracket and junction box are also made of die-casted aluminium. The signal converter housing is on both ends closed by a cylindrical cover with M115x2-6H6g screw-thread and O-ring sealing. The signal converter has an ingress protection degree of IP 65/IP 67 conform to EN 60529. 1.3.1 Electronics compartment The electronics compartment accommodates the pre-certified IFC 090...-EEx electronics unit with approval number PTB 98 ATEX 2012 U. The compartment is designed with type of protection flameproof enclosure"d"according to EN 50018 and closed by a threaded flameproof display cover. The IFC 090...-EEx unit is inserted into the electronics compartment via two sliding rubbers that position and fixate it at the front in the housing. Two M4 screws mount the unit and a third M4 screw fixates the copper earth strip at the back-end of the safety barrier printed circuit board.The three screws are screwed to the integrated aluminium wall in-between terminal and electronics compartment.The safety barrier provides the electrodes inside the primary head with type of protection intrinsic safety"ib"according to EN 50020. See tables on the next pages for the electrical data of the available power supplies(e.g. mains voltages, etc.).The safety barrier has the following maximum values (entity parameters): Maximum output voltage Uo =9 V Maximum output current to =38 mA Maximum allowed external capacitance Co =4.9 pF Maximum allowed external inductance Lo =23 mH 1.3.2 Terminal compartment The terminal compartment has seven M4 clamp terminals for connection of the power supply and signal output circuits(binary and current outputs). Section 2 shows the terminal arrangement for the regular and MODIS version of the IFC 090/...-EEx signal converter. The terminals are separated from each other by insulation plates(nine in total, one at each end).The terminal arrangement of the MODIS version (i.e. IFC 090i-EEx)is shown in Sect. 2.6. 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(i.e. current, pulse resp. status output)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 or E-generation approved "EEx e"cable glands. The terminal compartment can also be provided as a flameproof enclosure"d", in which case ATEX or E- generation approved"EEx d"cable glands of size Pg13.5, Pg16 or M20x1.5 are 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.All used cable glands, blind plugs and sealing devices for conduit systems must have an ingress protection degree of IP65 or better.

The two modules each use two terminals of the bottom four terminals of the flameproof terminal feed-through in the dividing wall between the electronics and terminal compartment of the signal converter housing, except for the combination with module DC-1 (only applicable for 24 Vac/dc versions),where only two of the four terminals are used. Interconnection of the two modules, P- SA with DC-1 or FA-ST with DC-1 is made internally. The flameproof terminal feed-through has seven terminals in total, the top two terminals are used for connection of the power supply,the third one is only used for mounting of a metal dividing plate with insulating cover plate.The remaining four are used for the intrinsically safe signal in- /output circuits of the installed MODIS modules. The metal dividing plate and the insulating cover plate warrant the required separation distances (i.e. clearances, creepage distances and distances through insulation)between the non- intrinsically safe power supply terminals and the intrinsically safe signal in-/output circuits.The insulating cover plate is provided with a sticker that contains important instructions how to remove and re-install the cover plate and the conditions under which it should be established (circuits not live !). Important ! Carefully follow the instructions on the sticker that is glued to the top of the insulating cover plate that covers the non-intrinsically safe power supply terminals ! KROHN6 ALTOFLUX IFC 090 F-EEx and ALTOFLUX IFC 090 F/1-EEx 15 For the connection diagrams of the intrinsically safe signal in-/outputs of the installed MODIS modules in the IFC 090i-EEx electronics unit(see next pages). It has to be noted that the intrinsically safe signal in-/outputs may only be connected to the following listed apparatus (registering devices like amp-meters, pulse counters, etc.): EEx-approved intrinsically safe apparatus; EEx-approved associated apparatus; Passive apparatus as defined in your national standard for installation of electrical apparatus in hazardous locations (e.g. EN 60079-14). Other types of apparatus may only be connected to the intrinsically safe signal in-/outputs through EEx-approved safety barriers, isolating interface units and the like.These barriers or units are not depicted in the connection diagrams for reasons of readability. It is assumed that they are an integrated part of the registering devices or as separate devices connected in series with them. The registering devices may only be installed in the hazardous location if they also have a type of protection for explosion safety according to the European Standards of the EN 500xx series, or if they are constructed as prescribed in your standard national code of practice. When the intrinsically safe signal in-/outputs are connected to other intrinsically safe or associated apparatus, the maximum safety values(i.e. entity parameters)of all intrinsically safe circuits have to be considered. Important! The 100...230 Vac power supply versions of the IFC 090i-EEx signal converter electronics unit with MODIS modules can only be equipped with passive outputs. Therefore the connection diagrams with the numbers 2,4, 5, 7, 9, 11 and 12 are applicable for the 100...230 Vac power supply versions.
