1. 1-1 <1. Introduction> Introduction Thank you for purchasing the DPharp EJX series pressure transmitter/EJA series pressure transmitter (“transmitter”). The transmitters are precisely calibrated at the factory before shipment. To ensure both safety and efficiency, please read this manual carefully before operating the instrument.
(a) Installation • This instrument may only be installed by an engineer or technician who has an expert knowledge of this device. Operators are not allowed to carry out installation unless they meet this condition. • With high process temperatures, care must be taken not to burn yourself by touching the instrument or its casing. • Never loosen the process connector nuts when the instrument is installed in a process. This can lead to a sudden, explosive release of process fluids.
1.3 <1. Introduction> 1-3 ATEX Documentation This section is only applicable to the countries in the European Union.
2. 2-1 <2. Connection> Connection The BRAIN communication signal is superimposed onto the 4 to 20 mA DC analog signal. Since the modulated wave is a communication signal, superimposing it on the normal signal will, from basic principles, cause no error in the DC component of the analog signal. Thus, monitoring can be performed via the BT200 while the transmitter is on-line. 2.1 2.
2.4 <2. Connection> 2-2 Integral Indicator Display When Powering On For models with the integral indicator code “D”, the display shows all segments in the LCD and then changes to the displays shown below sequentially. All segments display Model name (3 s) Communication Protocol (3 s) – – – – (3 s) F0200.ai NOTE For output signal code “D”, this function is available for software revision 2.02 or later. Software revision can be checked by the parameter M15: SOFT REV.
3. 3-1 <3. Operation> Operation The transmitter is equipped with BRAIN communications capabilities, so that range changes, Tag No. setup, monitoring of selfdiagnostic results, and zero point adjustment can be handled remotely via the BT200 BRAIN TERMINAL, the FieldMate Versatile Device Management Wizard or the CENTUM CS console. This section describes procedures for setting parameters using the BT200. For further information on the BT200, see the BT200 User’s Manual (IM 01C00A11-01E).

3-6 <3. Operation> 3.2.3 Setting Parameters Set or change the parameters as necessary. After completing these, do not fail to use the “DIAG” key to confirm that “GOOD” is displayed for the selfdiagnostic result at _60: SELF CHECK. (1) Tag No. Setup (C10: TAG NO) This is the panel for confirming set data. The set data items flash. When all items have been confirmed, press the again. (To go back to the setting panel, press the (NO) key. SET C10:TAG NO.
b. Setting Calibration Range Lower Range Value and Upper Range Value (C21: PRES LRV, C22: PRES URV) • Example 2: With present settings of 0 to 30 kPa, set the upper range value to 10 kPa. These range values are set as specified in the order before the instrument is shipped. Follow the procedure below to change the range. • The measurement span is determined by the upper and lower range limit values.
(4) Output Mode and Integral Indicator Display Mode Setup (C40: OUTPUT MODE, I20: P DISP MODE) (5) Output Signal Low Cut Mode Setup (D10: LOW CUT, D11: LOW CUT MODE) The mode setting for the output signal and the integral indicator can be performed independently. This mode is set as specified in the order when the instrument is shipped. Follow the procedure below to change the mode.
The low cut point has hysteresis so that the output around the point is behaved as below figure. Output mode: Linear Low cut mode: Zero Low cut: 20.00% Output Low cut point Setting range: 0 to 20% (6) Integral Indicator Scale Setup The following five displays are available for integral indicators: input pressure*1, % of range, user set scale, input static pressure, and % of static pressure range*1.
a. Display Selection (I10: DISP OUT1) • Example: Set an engineering unit M. Select the variable for the parameter I10: DISP OUT1 to display on the integral indicator. Set M. SET I30:ENGR.UNIT Press the M_ • Example: Change the integral indicator scale from % of range to input pressure display. Use the SET I10:DISP OUT1 PRES % < PRES < PRES % < ENGR.PRES < SP > > > > ESC SET I10:DISP OUT1 PRES FEED 3-10 <3. Operation> key to select PRES.
3-11 <3. Operation> d. Setting Static Pressure Unit and Scale (D30: SP UNIT, D33: SP LRV, and D34: SP URV) (9) Impulse Line Connection Orientation Setup (D15: H/L SWAP) Static pressure can be displayed in measured input static pressure or in %, independent from the 4-20 mA output signal of measured pressure or differential pressure. These parameters allow the entry of the static pressure unit and scale to be displayed. This function reverses the impulse line orientation.
Standard specifications a. Setting Password (D57: NEW PASSWORD) The burnout direction switch is set to HIGH. If a failure occurs, the transmitter outputs a 110% or higher signal. • Example: Set the password to 1234ABCD. Enter 1234ABCD. SET D57:NEW PASSWORD Press the to enter the setting. 1234ABCD Option code /C1 The burnout direction switch is set to LOW. If a failure occurs, a –5% or lower output is generated. CODE CAPS CLR FEED Slide switch position: H Press the (OK) key.
(12) Output Status Setup when a Hardware Error Occurs (D26: ERROR OUT) ● Output mode “LINEAR” 20 mA (100% display) This parameter allows the setting of the output status when a hardware error occurs. The following selections are available. (a) BURNOUT DIR; Outputs the corresponding values of 110% or –5% of output signals according to the setting by burnout direction switch (BO) on the CPU board. (b) HOLD; Outputs the last value held before the error occurred.
Note that changing the upper range value does not cause the lower range value to change but does change the span. • Example 2: When the upper range value is to be changed to 10 kPa with the present setting of 0 to 30 kPa, take the following action with an input pressure of 10 kPa applied. SET H11:AUTO P URV 30 kPa + 30 Press the key twice. The upper range value is changed to 10 kPa. ESC Press the SET H11:AUTO URV 10.000 kPa FEED 3-14 <3.
3-15 <3. Operation> a-3. Using External Zero-adjustment Screw Transmitter measures pressure of 0.03585 kPa. A11:PRES 0.03585 kPa SET J11:P ZERO ADJ 0.00000 kPa + 0 DEL CLR A pressure of 0 kPa is applied. Press the ESC SET J11:P ZERO ADJ 0.00000 kPa FEED NO key twice after the pressure has become stable. Note that the parameter J55: EXT ZERO ADJ must be ENABLE to perform this adjustment. Zero adjustment is completed.

Setting a lower point Transmitter indicates 9.94 kPa as SET J10:ADJ PRES 9.94000 kPa its output when applying a standard pressure of 10 kPa. ESC SET J11:P ZERO ADJ 9.94000 kPa + 10 DEL CLR Set 10. • Example: For the range of 10 to 30 kPa. J15: P ZERO DEV = –0.04 kPa J16: P SPAN DEV = –0.03 kPa Suppose that a standard pressure of 10 kPa is applied and the value of the parameter J10: ADJ PRES is 9.94 kPa.
<3. Operation> c. Sensor Trim for Static Pressure (J21: SP ZERO ADJ, J22: SP SPAN ADJ, J25: SP ZERO DEV, J26: SP SPAN DEV) NOTE For the transmitters (Except for EJX120A/EJA120E), zeroing and full sensor trim of the static pressure is performed in the same way as with the primary process variable (PV). Note that the static pressure sensor trim should be done only after trimming the PV. d.
• Example: Set the number of coodinates on the line graph to 5. Set 5. SET T11:NUM OF POINT 9 5 CLR Press the NO key twice to enter the setting. ESC Press the SET T11:NUM OF POINT 5 FEED 3-18 <3.

SET G10:P AL MODE INHIBIT < INHIBIT < HI.AL DETECT < LO.AL DETECT < HI/LO.AL DETECT Use the > > > > ESC SET G10:P AL MODE HI.AL DETECT OK FEED NO or key to select HI. AL DETECT.
• Example: Set the status output to output an off signal when the input pressure exceeds 75 kPa with its alert mode of HI. AL DETECT. Use the SET E50:DO SELECT INHIBIT < INHIBIT < PRES < SP < TEMP > > > > ESC SET E50:DO SELECT PRES FEED or key to select PRES. Press the key twice to enter the setting. Press the (OK) key.
