5. INSTALLING IMPULSE PIPING 5. INSTALLING IMPULSE PIPING 5.1 Impulse Piping Installation Precautions 5.1.2 Routing the Impulse Piping (1) Process Pressure Tap Angles If condensate, gas, sediment or other extraneous material in the process piping gets into the impulse piping, pressure measurement errors may result. To prevent such problems, the process pressure taps must be angled as shown in Figure 5.1.2 according to the kind of fluid being measured. 5.1.
5. INSTALLING IMPULSE PIPING (2) Position of Process Pressure Taps and Transmitter If condensate (or gas) accumulates in the impulse piping, it should be removed periodically by opening the drain (or vent) plugs. However, this will generate a transient disturbance in the pressure measurement, and therefore it is necessary to position the taps and route the impulse piping so that any extraneous liquid or gas generated in the leadlines returns naturally to the process piping. 5.
6. WIRING 6. WIRING 6.1 Wiring Precautions IMPORTANT • Lay wiring as far as possible from electrical noise sources such as large capacity transformers, motors, and power supplies. • Remove electrical connection dust cap before wiring. • All threaded parts must be treated with waterproofing sealant. (A non-hardening silicone group sealant is recommended.) • To prevent noise pickup, do not pass signal and power cables through the same ducts.
6. WIRING (2) Intrinsically Safe Type For intrinsically safe type, a safety barrier must be included in the loop. 6.3.4 Check Meter Connection Connect the check meter to the CHECK + and – terminals (use hooks). • A 4 to 20 mA DC output signal from the CHECK + and – terminals. Hazardous Location (Note) Use a check meter whose internal resistance is 10 Ω or less.
6. WIRING (2) Flameproof Type Wire cables through a flameproof packing adapter, or using a flameproof metal conduit. 䊏 Wiring cable through flameproof packing adapter. • Apply a nonhardening sealant to the terminal box connection port and to the threads on the flameproof packing adapter for waterproofing. Apply a non-hardening sealant to the threads for waterproofing. 6.5 Grounding Grounding is always required for the proper operation of transmitters.
7. OPERATION 7. OPERATION Confirming that Transmitter is Operating Properly Using the BT200 • If the wiring system is faulty, ‘communication error’ appears on the display. • If the transmitter is faulty, ‘SELF CHECK ERROR’ appears on the display. 7.1 Preparation for Starting Operation This section describes the operation procedure for measuring a pressure as shown in Figure 7.1. NOTE PARAM C60:SELF CHECK ERROR Confirm that the process pressure tap valve, drain valve, and stop valve are closed.
7. OPERATION 7.2.1 When you can obtain Low Range Value from actual measured value of 0% (0 kPa, atmospheric pressure); 7.2 Zero Point Adjustment Adjust the zero point after operating preparation is completed. For pressure measurement using gauge pressure transmitters, follow the step below before zero point adjustment. 1) Close the tap valve (main valve). 2) Loosen the fill plug so that the pressure applied to the transmitter is only the head of the seal liquid. 3) Adjust the zero point at this status.
7. OPERATION 7.2.2 When you cannot obtain Low Range Value from actual measured value of 0%; 7.3 Starting Operation After completing the zero point adjustment, follow the procedure below to start operation. Convert the actual measured value obtained by a digital manometer or a glass gauge into %. 1) Confirm the operating status. If the output signal exhibits wide fluctuations (hunting) due to periodic variation in the process pressure, use BT200 to dampen the transmitter output signal.
7. OPERATION 7.5 Setting the Range Using the Range-setting Switch IMPORTANT • Do not turn off the power to the transmitter immediately after completion of the change in the LRV and/or HRV setting(s). Note that powering off within thirty seconds after setting will cause a return to the previous settings. • Changing LRV automatically changes HRV to the following value.
