Baker Hughes Panametrics XDP, User Manual

24

To configure the XDP output, navigate to the 

cal>1:cal>setup>analog output

 menu and proceed as follows:

1.  At the 

analog output

 menu option press [ENTER].

2.  Use the [



] and [



] keys to highlight the 

Aout type

option and press [ENTER].

3.  Use the [



] and [



] keys to highlight the menu option  

for the desired output type and press [ENTER].

4.  Use the [



] and [



] keys to highlight the 

zero setpoint

option and press [ENTER].

5.  Using the four arrow keys, program the mA/pcnt 

measurement value that corresponds to the low end  

of the chosen analog output range. Press [ENTER].

6.  Use the [



] and [



] keys to highlight the 

span setpoint

option and press [ENTER].

7.  Using the four arrow keys, program the ppm/pcnt 

measurement value that corresponds to the upper end 

of the chosen analog output range. Press [ENTER].

4.6.2a  Error handler options

At this point, the programming of the XDP analog output 

differs from that of the system analog output described in 

the previous section. The difference lies in the programming 

of error handlers for the following six fault conditions:
•  Input mA over range
•  Input mA under range
•  Zero drift/cal > max drift/cal
•  Zero drift/total > max drift/total
•  Span drift/cal > max drift/cal
•  Span drift/total > max drift/total

NOTE: 

See 

"Chapter 5. Calibration" on page 27

, for 

instruction on viewing the current values for last four 

parameters listed above.

4.6.2b  Configuring the error handlers

To set up the error handlers, continue the programming  

as follows:
1.  At the 

error handlers

 menu option press [ENTER].

2.  Use the [



] and [



] keys to highlight the desired  

fault condition

 error handler (see list on previous page) 

and press [ENTER].

3.  Use the [



] and [



] keys to highlight either the 

enable

or the 

disable

 option and press [ENTER].

4.  If you 

disabled

 this error handler, skip to step 7. If you 

enabled

 this error handler continue with the next step.

5.  Use the [



] and [



] keys to highlight the manner in which 

you want the XDP to respond to a fault in this parameter:
• 

Force high

 - displays a value equal to the high point 

of the selected analog output range (e.g. 20 mA for a 

4-20 mA range).

• 

Force low

 - displays a value equal to the low point  

of the selected analog output range (e.g. 4 mA for  

a 4-20 mA range).

• 

Force to value

 - displays a preprogrammed value.

• 

No effect

 - displays the current live value

• 

Hold last value

 - displays the last valid measurement 

prior to the fault condition. 

  After making your choice, press [ENTER].
6.  If you selected 

force high, force low, no effect

, or 

hold  

last value

, go to step 7. If you selected force to value, 

proceed as follows:
a.  Using the four arrow keys, program the ppm/pcnt 

measurement value that should be displayed if there 

is a fault condition in this parameter. Press [ENTER].

b.  Press [ESC] twice.

7.  Return to step 2 to program additional error handlers, 

until all of the error handlers have been configured.

4.6.2c  Testing and trimming the analog output

Having set the basic parameters for the analog output, the 

output should now be tested and trimmed by continuing  

as follows:
1.  Use the [



] and [



] keys to highlight the test option  

and press [ENTER].

2.  Enter a test percentage (0-100%) based on the full scale 

value for the chosen analog output type (e.g. a 50% 

test value for the 4-20 mA range would be 12 mA). Press 

[ENTER] to leave the edit box and press [ENTER] again at 

either the 

test, zero trim

, or 

span trim

 menu choice to 

send the test value to the analog output device.

3.  Repeat step 2 for as many test percentages as desired, 

then press [ENTER].

IMPORTANT

Before proceeding, make sure the output percentage to be 

trimmed has been entered in the test menu.

4.  Use the [



] and [



] keys to highlight the 

zero trim

 option 

and press [ENTER].

5.  Use the [



] and [



] keys to trim the zero point until  

your output device reads the exact value for the low  

end of the chosen analog output range (e.g. 4 mA for  

a 4-20 mA range). Press [ENTER].

6.  Use the [



] and [



] keys to highlight the 

span trim

 option 

and press [ENTER].

7.  Use the [



] and [



] keys to trim the span point until  

your output device reads the exact value for the high  

end of the chosen analog output range (e.g. 20 mA for  

a 4-20 mA range). Press [ENTER].
