4.2 Setting Parameters

This section describes how to input individual parameter data and write the data to the JUXTA instrument from the parameter setting display (the SET dialog box).

4.2.1 Entering a Setting V alue and Writing It to JUXT A

The following describes how to change the input range of JUXT A VJH7 (isolator unit) with reference to the example of changing the input range from 1 to 5 V DC, to –10 to 10 V DC.

Step 1 In the SET dialog box, open the SET (I/O) page. Then double-click the data cell of

parameter D22: INPUT1 L_RNG.

4-3

Step 2 The text box at the bottom becomes available, showing the current setting

Step 3 In the text box, type -10 and click WRITE. The new data is written to the JUXT A

instrument, and the display data in the cell is updated from 1 to –10.

IM 77J01J77-01E 2nd Edition : Jan.30,2004-00

CAUTION

After you click WRITE, the data value shown in the data cell may be different from the value you entered in the text box. This is because the JUXT A instrument has limits for some of its parameters, and if the entered value is outside the limits, the instrument automatically sets the parameter to the nearest limit value.

Step 4 In the same way as Step 1 to Step 3, set the 100% value of the input range by

double-clicking the data cell of D23: INPUT1 H_RNG.

Step 5 Enter 10 in the text box and click WRITE. The data is written to the JUXT A

instrument, and the display data is updated from 5 to 10.

The input range of the connected JUXT A instrument has now been changed from 1 to 5 V DC, to –10 to +10 V DC.

4.2.2 Notes on Setting Parameters

The input range/output range of a JUXT A instrument can be set in two ways, depending on the model of the instrument.

(1) Models for which 0% and 100% values of the range are set:

4-4

The high range limit and low range limit are represented as L_RNG and H_RNG, as in INPUT L_RNG and INPUT H_RNG.

(2) Models for which the span value and span of the range are set:

The 0% value and span are represented as ZERO and SP AN, respectively , as in INP ZERO and INP SP AN.

For example, to set an input range of –10 to 10 V DC:

• In case (1), set –10 for INPUT L_RNG and 10 for INPUT H_RNG.

• In case (2), set –10 for INP ZERO and 20 for INP SP AN.

WARNING

When you set the range of a JUXT A instrument, confirm the respective parameter codes to determine whether they are L_RNG and H_RNG, or ZERO and SPAN, to make sure that you set 0% and 100% values of the range or set the 0% value and span.

CAUTION

For a numeral parameter , the number of significant digits is 4. For example, if you enter 12345, the data value will be written as 12340 and if you enter 0.12345, the data value will be written as 0.12340.

IM 77J01J77-01E 2nd Edition : Jan.30,2004-00

4.2.3 Selecting an Item from a List Box and Writing It to JUXTA

As an example of procedures to select an item from a list box and write it to the JUXT A instrument, the following shows how to change the communication protocol for a JUXT A VJH7 (an isolator whose output 2 is a communication port) from MODBUS ASCII to MODBUS RTU.

Step 1 In the SET dialog box, click the SET (COM) tab. The SET (COM) page contains

the communication settings.

10.2 Performing Fine Adjustment of Input

This section describes how to perform fine adjustments of inputs. The following shows an example when doing so for a JUXT A VJH7 isolator . For wiring with a calibrator or other apparatuses, see the instruction manuals for respective JUXT A instruments.

10.2.1 Adjusting the Zero Point of Input

Step 1 Apply the 0% level of the input to the JUXT A instrument. If the signal level after A/

D conversion in the JUXT A instrument (the value displayed in the P02: ZERO

ADJ1 data cell) and the value actually input do not match, perform the following

steps to offset the zero-point shift. Step 2 Double-click the P02: ZERO ADJ1 data cell. The text box at the bottom of the

ADJUST dialog box turns becomes available. Step 3 Click the down arrow next to the text box to open a list, which contains the follow-

ing:

10-3

+*.* V INC: Adds the specified voltage after A/D conversion.

+*.* V DEC: Subtracting specified voltage after A/D conversion.

+*.* V RST: Resets the value that has been adjusted by INC or DEC to 0.

HINC or HDEC: Adjusts the value by about 10 times that specified by the +*.*

INC or +*.* DEC command.”

Step 4 Since the value shown in the P02: ZERO ADJ1 cell is larger than the actual input

level in the example above, select +*.* V DEC and click WRITE. Repeat this

procedure to complete the adjustment.

10.2.2 Adjusting the Input Span

Apply the 100% level of the input to the JUXT A instrument. If the signal level after A/D conversion in the JUXT A instrument (the value displayed in the P03: SP AN ADJ1 data cell) and the actual input signal level do not match, you must correct the input span. The procedure is the same as above.

IM 77J01J77-01E 2nd Edition : Jan.30,2004-00

CAUTION

For some models, +*.* HINC and +*.* HDEC are not included in the list. The unit of signal differs depending on the model.

10.3 Correcting the Output

This section describes how to perform corrections of outputs. The following shows an example when doing so for a JUXT A VJH7 isolator . For wiring with a calibrator or other apparatuses, see the instruction manuals for respective JUXT A instruments.

Step 1 Double-click the P12: OUT1 0% data cell and click WRITE. The 0% level is then

forcedly set to the output regardless of the input level. Calculate the percent value

of the deviation from zero in the reading of the calibrator . If there is a positive

deviation, correct it by setting a negative percent value to offset the deviation.

For example, provided the output signal range of the JUXTA instrument is

4—20 mA DC and the reading of the calibrator when forcibly outputting the

0% value is 3.96 mA DC, the error (%) can be calculated as follows and set

the same value to the opposite polarity.

10-4

Error (%) = [(measured value – reference value)/span] × 100

= [(3.96 – 4.00)/16] × 100 = –0.25

Step 2 In this example, the output level read in step 1 showed the –0.25% deviation.

Hence, you should type 0.25 in the text box and click WRITE. Check that the

reading of the calibrator is within the range of rated accuracy and quit the proce-

dure.

In the same way, correct the 100% output level. Step 3 To correct the 100% output level, double-click the P13: OUT1 100% data cell and

follow steps 1 to 2.

10.4 Setting Wire Resistance Compensation

If the input wiring resistance is causing a significant error after the wiring to the field device has been completed, you can compensate for the wiring resistance with the following procedure.

Step 1 Change the wiring connections in the field as shown at the bottom of this page. Step 2 When the input is stable, double-click the P01: WIRING R data cell.

10-5

Step 3 Click the arrow next to the text box. Choose EXECUTE from the list and click

WRITE. The wiring resistance is then compensated.

10.5 Using the Forced Output Function

Using the forced output function allows you to perform function tests of the equipment connected to the JUXT A instrument’ s output terminals.

Step 1 In the ADJUST dialog box, click the TEST tab. Step 2 Double-click the Q02: OUT1 TEST data cell. In the text box, enter the percent

value of the level you want to output. T o output the 100% value forcedly for ex-

ample, type 100 and click WRITE.

The 100% value is then output. During forced output, the selected cell is yellow .

Step 3 T o cancel forced output, click Cancel Forced Output or double-click another

parameter .

TIP

The ADJUST dialog box for some models of JUXT A does not have the TEST page on which you can forcibly set an output level. Even with such models however , it is possible to output 0% and 100% levels forcedly by the same procedure as that used for output correction. To do so, double-click the OUT 0% or OUT 100% data cell and click WRITE.
