ELECTRICAL CONNECTIONS SITRANS FX300 4.4 Earthing and equipotential bonding CAUTION! Equipotential bonding Equipotential bonding Equipotential bonding Equipotential bonding Vortex flowmeter converters must be included in on-site equipotential bonding as per EN60079- 14! They are connected to the PA terminals. For compact measuring devices and measuring sections with flange connections, the connection may be made via a conducting connection of the sensor to the pipe. -
Page 16: Sensor Circuits (Remote Version Only)
ELECTRICAL CONNECTIONS SITRANS FX300 4.5 Sensor circuits (remote version only) Observe the following points when connecting the sensor to the converter: • Use only the supplied connecting cable (max. length 30 m / 98 ft). • Before connecting or loosening the equipotential bonding cable, ensure there are no differences in potential. -
Page 17: Operation
OPERATION SITRANS FX300 5.1 Start-up Start-up may only commence when the vortex flowmeter: • is correctly installed in the system and connected. • has been checked for the proper state with regard to its installation and connection requirements. • and the electronics compartment have been properly closed (flameproof enclosure) and the applicable special lock has been fitted. -
Page 18: Service
The device should be de-energised before opening the flameproof enclosure. Observe warning without fail. Exchanging the device insert It is permitted to replace a complete device insert VFC070 / SITRANS FX300 with a version constructed in the same way. 05/2015 - SFIDK.PS.050.G1.02 A5E02172013... - Page 19 SERVICE SITRANS FX300 Take special note of the following figure and: • ensure that the construction is the same by checking the nameplates. • the connecting cable of the sensor circuits is to be laid in the cutout provided on the printed circuit board.
