3-13. Installation3.1 Transmitter MountingTransmitter may be mounted in any position.After transmitter is mounted, tighten all bolts.Pipe may be clamped to another pipe, or flangedand bolted to floor or wall.U-bolt secures assembly to 2" pipe. U-bolt may berevolved 90° for use with horizontal pipe.For fixed regulator and associated parts, refer toCustomer Maintenance Parts List involved.Optional air-set can be mounted as illustratedbelow.3.2 Air Supply and TransmissionPipingTransmitter1/4" (8A) TubingOutput gaugeSupply gauge(optional)Shut off valveAir supplyAir filter-regulator (optional)ReceiverF0303.aiFigure 3.3Air Supply and Transmission PipingU-bolt2" PipeEither set ofmounting holesmay be used.BoltNOTE• Air supply must be regulated at 1.4 kgf/cm 2or bar, 140 kPa, or 20 psi.• Transmitter uses 0.5 Nm 3 /h of air in normaloperation.• Air must be clean and dry. Blow out filterregularly.• Transmission line must be free of leaks.F0301.aiFigure 3.1Transmitter MountingLowpressureHighpressureBypassF0302.aiFigure 3.2Typical Transmitter PipingIM 02C01B06-01E
4. Operation4.1 Zero Adjustment4.1.1 WITHOUT Zero Elevation or ZeroSuppression Kit.Make adjustment with transmitter in operatingposition.1. Disconnect line to receiver. Connect 0-1.5kgf/cm 2 or bar, 0-150kPa, or 0-22 psi pressuregauge to OUT connection. 4-14.1.2 WITH Zero Elevation or ZeroSuppression Kit.Make adjustment with transmitter in operatingposition.1. Disconnect line to receiver. Connect 0-1.5kgf/cm 2 or bar, 0-150kPa, or 0-22 psi pressuregauge to OUT connection.Air supplyLow pressure lineHighpressure lineAir supplyBypass valve<strong>Pressure</strong>gaugeF0401.ai2. Adjust air supply to pressure at whichtransmitter will be operated.3. Close both pressure connection valves, andopen bypass valve. Slowly open high pressureconnection valve to apply static pressure toboth sides of transmitter.4. Adjust zero screw so that pressure gauge reads0.2kgf/cm 2 or bar, 20 kPa, or 3 psi.<strong>Pressure</strong>gaugeF0403.ai2. Adjust air supply to pressure at whichtransmitter will operate.3. For suppressed-zero ranges: Close bypassvalve. Apply pressure equal to amount of zerosuppression to high pressure side. Vent other side.For elevated-zero ranges: Close bypassvalve. Apply pressure equal to amount of zeroelevation to low pressure side. Vent other side.4. Adjust screw so that pressure gauge reads 0.2kgf/cm 2 or bar, 20 kPa or 3 psi.Zero adjustmentscrewAdjustmentscrewF0402.ai5. Reconnect OUT piping. If necessary, changezero adjustment on receiver so that readingis zero. Close bypass valve and open lowpressure connection valve. Transmitter is nowin operation.F0404.aiIllustrated is transmitter with zero suppressionkit. If transmitter has zero elevation kit,adjustment screw is on opposite side.5. Reconnect OUT piping. If necessary, changezero adjustment on receiver so that it readszero. Open bypass valve, then open pressureconnection valves. Close bypass valve.Transmitter is now in operation.IM 02C01B06-01E
