6.7.2.3.2 Regulator Valve Settings
1. Flow Meter Sampling - the default setting is
"Standard".
a. The optional "Reduced" sensitivity setting
slows the reaction time of the regulator
valve.
i. This
may be required for very low
flow rates, or if flow is highly
irregular or worn equipment.
2. Close Valve When Off -
some regulating
valves are a combination regulating and on/off
valve, which means they must close when the
tank is turned off.
a. Select this option if this type of valve is
being used to ensure it is closed when the
tank is turned off.
i. A common example of this valve is
the Raven fast valve.
3. Reverse
V
alve - this will allow for the polarity
of the regulating motor of NH3 or liquid
systems to be reversed to achieve correct
operation direction.
4. Dump Valve - used to apply a signal to a
dump
valve or master valve.
a. Enabled - applies power when tank is off.
b. Reversed - applies power when tank is on.

5. Controller Mode - this is the controller model
selection.
a. For liquid
systems, most use the
"Standard" model that is a 12V Spraying
Systems type of regulator valve or choose
from Micro-Track, Dickey-John or Raven
model.
b. For NH3
systems, choose from either a
Micro-trak, Dickey-John or Raven model.
6. Minimum
On
Time - is the minimum amount
of time the controller will pulse the valve,
when it is trying to make a small correction.
7. Maximum On
Time - is the maximum
amount of time that the controller will pulse
the control valve before checking the rate.
a. It is used to make a large correction for
the rate.
8. Gain
Setting - is a software setting that either
increases
or reduces how hard the controller
tries to stay on rate.
a. The higher the Gain setting, the faster the
valve responds.
b. If this number is set too fast, it will lead
to an overshoot, which then has to be
corrected.
