The value is adjusted using the two arrow keys, the UP arrow will
take the current output up, and the DOWN arrow will take it down.
Press the ENTER key when the correct output current is displayed
on the ammeter.
NOTE
Zero mA should be set up no matter what has been selected as the base of
the current output. This is factory set by Rosemount Analytical.
g. In a similar manner to the above, the
current output level should now be set
to 20 mA.
6. The next menu to be configured is the
Parameters menu - options are given below.
Select this option by pressing the ENTER
key. The ARROW keys will now display
the available options from within this
sub-mode, when the option that requires
changing is displayed, press the ENTER key. When all required
changes have been made, select the EXIT option and press ENTER.
a. Security Number
To prevent any unauthorized
tampering with the set up information,
it is important that the security code is
changed from the factory setting. Each
digit is selected with the ENTER key and changed with the ARROW
keys.
NOTE
It is important to make a note of this number, otherwise it will not be possible
to change the instrument setup.
b. Identity Number
If the system is being used as part of
an integral monitoring system and the
serial input and outputs are being
used, the central processor requires a
'Device Identity' to identify each instrument. This number must be
unique for each equipment item and can be set from 1 to 30 as
required. See the IEM Communication Equipment Manual (Doc. ID:
0006/6) for details.
c. Measurement Path Length.
NOTE
The current value entered for the path length will be displayed for 1 second
then the display will default to zero. The path length must be re-entered for
the unit to calculate gas concentrations correctly. (The display following
shows the screen after 1 second, before the path length is reconfigured).
