3.3. Set moisture control levels and pulse irrigation
3.4. Adjustable thresholds
When setting the control conditions, it is
useful to give a name to the threshold level
(“DRY_level” in this example). You will then
be able to adjust the thresholds later without
starting and stopping the program (this
feature requires DeltaLINK version 2.4 or
later).
3.5. Configure the GP1
Save the program and close the
program editor.
In the main
DeltaLINK
window,
select the
Program
view and click
on the
Change
button.
Select
File
,
Import Program
…
,
and select the program file (.pg6)
that you have just saved.
Switch to the
Control
tab.
Click on
Insert...
and select Moisture1 to
control irrigation
ON
with an appropriate
moisture threshold (see next section, 3.4).
Set the
OFF
conditions similarly.
Set the GP1 to
check the
OFF
conditions more
often than the
recording rate.
If
Duty cycle
< 100% the GP1 will pulse the
irrigation so that the compost has time to wet
up. In this example the irrigation would be
pulsed
ON
for 30 seconds every 2 minutes.
