If a pressure source and a manometer are combined: This section describes procedures for setting parameters using the BT Manial the key twice in the setting panel panel 1 to clear all error message P10 to P13 information. Note 1 Units set using Engineering unit D21 are not indicated.
Power Supply Wiring Connection When combining with Optional code F1, output status for down-scale is —2. You must press the shift key before entering each letter. Maintenance of the transmitter is easy due to its modular construction. It may also be used to alert against unsafe practices.
Yokogawa’s DPharp active sensor and rugged construction allow users to run their plants safer and with less downtime.
Model And Specifications Check If you have difficulty isolating or correcting a problem, contact Yokogawa service personnel. If the output signal exhibits wide fluctuations hunting due to periodic variation in the process pressure, use BT to dampen the transmitter output signal. When water hammer is to be occurred, please take measures to prevent the mamual from exceeding PS by setting the safety valve, etc. An integral indicator can be installed in the following three directions.

Press the [F4] OK key to release test output immediately. Fluoro-rubber O-ring All Eja530aa of amplifier housing. NO Fully close equalizing valve, and fully open high pressure and low pressure valves.
YES Does the selfdiagnostic indicate problem location? The following symbols will appear in sequence, one at a time, at the cursor each time you press [F1] CODE: Change the unit from mmH2O to kPa.
Check Meter Connection NOTE Draws attention to information essential for understanding the operation and features.

If the error code still exists, replace the capsule assembly. Are power supply voltage and load resistance correct? Since some problems have complex causes, these flow charts may not identify all.
Read carefully before using the transmitter. When doing so, be sure to observe the following. Differential pressure transmitters, which serve as the core of field instrumentation, are widely used to measure the flow rate, pressure and density of liquids, gases and steam, as well as the level of liquid in a tank. Replacing The Cpu Board Assembly Holds output immediately before error occurrence. When the transmitter is delivered, visually check them to make sure that no damage occurred during shipment.
It is recommended to set a low-pass filter approximately 0.
See Chapter 8 for BT operation. Insert the pin CN4 as shown in the figure above to set the burn-out direction.
ema530a Applicable for Output signal code D and E. Note 2 Indication limits — to NO If the problem is in the measurement system, isolate the problem and decide what corrective action to take.

NO Refer to error message summary in Subsection 8. See page After locking, the covers should be confirmed not to be opened by hand.
Please use this instrument in the industrial environment only. Is power supply polarity correct? When the instrument is shipped, the damping time constant is set at 2. Zero adjustment is completed. Selecting The Wiring Materials Sets the calibration range for 4 to 20 mA DC.
