Section 5. Programming
5-21
The display will show a new screen
containing the option title 4-20mA INPUT
on the top line and a 7 digit number with the
leftmost digit flashing as a prompt for input.
The 4-20 mA input will be converted by the
controller to pulses, proportional to the span
of the input, at the rate set in the
specifications. To set the number of pulses
required to be input before a sample is taken,
use the ARROW keys to move the flashing
prompt until it is over the digit requiring
change.
Press a number key (0-9) to replace any
existing number and advance the flashing
prompt to the next digit to change. Replace
digits as required, then press ENTER.
The display will echo the last entry with
<ENTERED>.
Any wrong entries will require re entry. If
ENTER has not been pressed, reposition the
prompt over the incorrect digit and replace
it. After ENTER has been pressed, the
entire entry must be redone from the
beginning (press SET).
The controller has now been given a new
value for SAMPLE INITIATION. The new
values reside in the NEW ENTRIES area of
the controller memory. To make these
changes active, press the RESTART key,
then again press it to confirm your choice.
The controller will then wait until the
required pulses have been received before
taking a sample.
