详细说明：FCS400 Quick Start[手册]pdf,Liquid applications Gas or vapor bubbles in the fluid may result in erroneous measurements, particularly in the density measurement Do not install the flowmeter at the highest point in the system, where bubbles will be trapped Install the flowmeter in low pipeline sections, at the bottom of a U-section in the pipeline Figure 3-1 Liquid applications, wrong location with trapped air/gas Gas applications Vapor condensation or oil traces in the gas may result in erroneous measurements Do not install the flowmeter at the lowest point of the system Install a filter Figure 3-2 Gas applications, wrong location with trapped oil Flow directlon The calibrated flow direction is indicated by the arrow on the sensor. Flow in this direction will be indicated as positive by default. The sensitivity and the accuracy of the sensor do not change with reverse flow The indicated flow direction(positive /negative)is configurable CAUTION Accurate measureme The sensor must always be completely filled with process media in order to measure accurately Orienting the sensor The sensor operates in any orientation The optimal orientation depends on the process fluid and the process conditions Siemens recommends orienting the sensor in one of the following ways 1. Vertical installation with an upwards flow(self-draining) FCS400 sensor A5E03922775007,05/2014 Figure 3-3 Vertical orientation, upwards flow 2. Horizontal installation, tubes down (recommended for liquid applications) Figure 3-4 Horizontal orientation, tubes down 3. Horizontal installation, tubes up(recommended for gas applications) Figure 3-5 Horizontal orientation; tubes up Note HyglenIc appllcations In 3A and EHEdG certified hygienic applications the flowmeter must be installed vertically as shown in 1 above Installation in a drop line Installation in a drop line is only recommended if a pipeline reduction or orifice with a smaller cross-section can be installed to create back-pressure and prevent the sensor from being partially drained while measuring FCS400 sensor 5E03922775-007,05/2014 Back pressure orifice On/off valve igure 3-6 Installation in drop line Mounting the sensor NOTICE Incorrect mounting The device can be damaged, destroyed or its functionality impaired through improper mounting Before installing ensure there is no visible damage present on the device Make sure that process connectors are clean, and suitable gaskets and glands are used Mount the device using suitable tools WARNING Unsuitable connecting parts Danger of injury or poisoning In case of improper mounting hot toxic and corrosive process media could be released at the connections Ensure that connecting parts(such as flange gaskets and bolts)are suitable for connection and process media Install the sensor in well-supported pipelines in order to support the weight of the flowmeter Center the connecting pipelines axially in order to assure a stress free installation the flowmeter must not be used to bring the rest of the pipework into line; make sure the pipework is correctly aligned before inserting the flow sensor Install two supports or hangers symmetrically and stress- free on the pipeline in close proximity to the process connections Note Handling Never lift the flowmeter using the housing, that is always lift the sensor body FCS400 sensor A5E03922775007,05/2014 Avoid vibration Make sure that any valves or pumps upstream of the sensor do not cavitate and do not send vibrations into the sensor Decouple vibrating pipeline from the flow sensor using flexible tube or couplings Figure 4-1 Non-flexible pipes not recommended in vibrating environment Figure 4-2 Flexible pipes recommended in vibrating environment Avoid cross talk If operating more than one flowmeter in one or multiple interconnected pipelines there is a risk of cross talk Prevent cross talk in one of the following ways Mount sensors on separate frames Decouple the pipeline using flexible tube or couplings × Figure 4-3 High risk of cross talk when using non-flexible pipes a duo upTmmmmmmng-u eo Figure 4-4 Low risk of cross talk when using flexible pipes and separate frames Installing the sensor cable Wiring sensor and transmiter(M12 The sensor is provided with a preformed cable terminated with M12 style stainless steel weather-proof plugs FCS400 sensor A5E03922775-007,05/2014 The cable screen is physically and electrically terminated within the body of the plug Take care when handling the cable and passing it through cable ducting that the plug is not subjected to excessive tension (pulling) as the internal connections may be disengaged Note Never pull the cable by the plug-only by the cable itself 1. Connect sensor using the supplied 4-wire cable with M12 connectors Note GroundIng The sensor cable screen is mechanically connected to the grounding terminal(PE), only when the M12 plug is correctly tightened Wiring sensor and transmitter (glands A: Preparing cable Prepare the cable by stripping it at both ends Blue White Yellow Orang Figure 5-1 Cable end B: Connecting at transmitte Remove lock screw and remove id 2. Remove one of the blind plugs and fit cable gland 3. Remove cap and ferrule from cable gland and slide onto cable 4. Push cable through open gland; anchor cable screen and wires with clamp bar 5. Connect wires to terminals according to list below Terminal number Description Wire color(siemens) +15 VDC Orange O VDC Yellow B White A Blue 6. Assemble and tighten cable gland 7. Remove o-ring from lid FCS400 sensor A5E03922775007,05/2014 8. Reinstate lid and screw in until mechanical stop Wind back lid by one turn 9. Mount o-ring by pulling it over the lid and tighten lid until you feel friction from the o-ring on both sides. Wind lid by one quarter of a turn to seal on the o-ring 10. Reinstate and tighten lid lock screw C: Connecting at sensor DSL 1. Remove lock screw and remove dsl lid 2. Undo the flexible strap 3. Disconnect sensor connection from dsl cassette 4. Loosen mounting screw using a TX10 Torx driver and remove DSL cassette from housing 5. Remove cap and ferrule from cable gland and slide onto cable 6. Push cable through open gland; anchor cable screen and wires with clamp bar. 7. Remove terminal block from dsl cassette 8.
