Maintenance / RepairD184B140U02 FSM4000 1059 Maintenance / RepairRepair and maintenance activities may only be performed by authorized customer servicepersonnel.When replacing or repairing individual components, original spare parts must be used.Notice - Potential damage to parts!The electronic components of the printed circuit board can be damaged by static electricity(observe ESD guidelines). Make sure that the static electricity in your body is dischargedwhen touching electronic components.9.1 Flowmeter sensorEssentially maintenance is not required for the flowmeter sensor. The following items should bechecked annually:• Ambient conditions (air circulation, humidity)• Seal integrity of the process connections• Cable entry points and cover screws,• Operational reliability of the auxiliary power feed, the lightning protection and the groundsThe flowmeter sensor electrodes must be cleaned when the flowrate information on thetransmitter changes when recording the identical flowrate volume. If the display shows a higherflowrate, the contamination is insulating. If the flowrate displayed is lower, the contaminationresults in a short-circuit.For repairs to the lining, electrodes or magnet coil, the flowmeter must be returned to the localoffice of ABB.ImportantWhen sending the flowmeter sensor to the local office of ABB, complete the return form in theappendix and include with device.When cleaning the exterior of meters, make sure that the cleaning agent used does not corrodethe housing surface and the gaskets.9.2 GasketsSome device designs are shipped with special gaskets. These gaskets must be used andinstalled properly to prevent leakage.For all other device designs, use commercially available gaskets made from a compatiblematerial for the fluid and prevailing temperature (rubber, PDFE, lt, EPDM, silicon, Viton, etc.).ImportantA flowmeter sensor in wafer configurations is installed without gaskets directly in the pipeline.
