correct setting to use. The range of settings is
to handle unusual situations, including very
long wire runs or increased wire resistance due
to the age of the wire. Increased Power Factors
may detract from the total power available to
the field, and should be used only after consult-
ing with Hunter Field Services.
To Edit a Decoder: Press Options repeatedly
until the displays shows “Edit Decoders?”,
and press ENTER. The display will show:
The first station to be shown is always the
Pump output, which counts as a station in
decoder systems (technically, the Pump is
station #0). Subsequent stations are shown by
their station number, from 1 to 103.
Since the cursor is already under the Serial
Number, you can type in a new decoder Serial
Number for the Pump, if that is the decoder you
want to edit. You must type all 8 digits, and
press ENTER.
To advance to another station #, you can simply
press the STATIONS button until the number of
the station you want to edit appears. You may
also use the NEXT button to move the cursor to
the station field (“Pump”), then type the num-
ber of the station you want to edit, and press
ENTER. The display will immediately show
the decoder information for the new station you
have entered.
Continue editing any other decoders (press
Stations again or type the station number as
described above), and when you are finished,
press EXIT. The display will show:
If you press ENTER, the changes will be saved.
You may also TOGGLE to “NO” and press
ENTER if you want to discard the changes.
Note: Decoder edits are automatically stored in
memory, and must be “dumped” every 4 edits.
If you edit more than 4 consecutive decoder
stations in a session, the display will periodi-
cally show the “Save Changes? YES|no” as
you advance with the STATIONS button. If
you want to save the changes you’ve already
made and continue editing, just press ENTER.
The display will briefly show SAVED! and
then the next Station.
Also, if you type the station numbers directly
into the station number field and press EN-
TER, you will also receive the “Save
Changes? YES|no” message if you entered a
station more than 4 digits higher than the last
one you edited. Just press ENTER. The display
will briefly show SAVED! and will then show
the Station you typed.
View SYS Events: This option allows you to
view (but not change) the events in the com-
puter-generated central System Program that
have been downloaded to the Field Controller.
These are the events created by either a Vista
or Surveyor central system.
To view the downloaded events, press OPTIONS
repeatedly until View SYS Events? appears in
the display, and press ENTER. The display will
show the first SYS event. The display will show
the event number, its start time, and the ET Day
on the first line, and the station number and its
run time on the lower line.
