Both circuits are securely galvanically isolated from all other non-intrinsically safe circuits up to a peak voltage of 375 V. The sensor coils circuit shall be connected to a passive load only. For further details about the electrical connection, see the handbook. For OPTIFLUX 2100 C/4100 C only: The housing must be connected to the equipotential bonding system of the hazardous area. See EN 60 079-14 clause 6.3. For this purpose the internal or external connection facility WE clamp) can be used. 20 www.krohne.com 04/2009-7.30685.22.00-EX IFC 100 en MAINTENANCE AND SERVICE p 5.1 Maintenance The flowmeters are maintenance free with respect to the flowmetering properties. Within the scope of periodic inspections required for electrical equipment installed in hazardous areas it is recommended to check the housing for signs of damage or corrosion. This is especially important for the flameproof Ex d flowmeter or coil housing of sizes DN25...150. Specific notes for Ex d flowmeters OPTIFLUX 2100 C/4100 C, sizes DN25...150: • In case of replacement of one or more of the four hexagon socket head cap screws which connect the converter housing with the sensor housing, equivalent types must be used: M6x16 hexagon socket head cap screws to EN ISO 4762, steel quality A2-70 or A4-70. • If needed, contact the manufacturer for information on the dimensions of the flameproof joints. Specific note for Ex q flowmeters OPTIFLUX 2100 C/4100 C, sizes DN25...150 and DN200...300: The coil housing is factory sealed.After opening of the seal the flowmeter must be returned to the manufacturer to re-fill the flowmeter with the Ex q approved powder filling material. 04/2009-7.30685.22.00-EX IFC 100 en www.krohne.com 21 MAINTENANCE AND SERVICE 22 www.krohne.com 04/2009-7.30685.22.00-EX IFC 100 en MAINTENANCE AND SERVICE 04/2009-7.30685.22.00-EX IFC 100 en www.krohne.com 23 r� r . rti,y • •• M• • • •• AW to ri KROHNE product overview • Electromagnetic flowmeters • Variable area flowmeters • Ultrasonic flowmeters • Mass flowmeters • Vortex flowmeters 0 • Flow controllers 0 • Level meters L 3 • Temperature meters v • Pressure meters L s • Analysis products • Measuring systems for the oil and gas industry v • Measuring systems for sea-going tankers 0 0 U LL X W 0 0 N Head Office KROHNE Messtechnik GmbH & Co.
