VALVE RESPONSE SPEED:
Allows adjustment of
response to “tune” the system for use with very fast or
slow valves. For example, if using a ball valve
that takes several seconds to open or close
in manual mode, and the system responds
sluggishly, use the “+” button to adjust the
valve response number to 1, 2 or
3. The range of adjustment is -2
to 3, factory setting is zero.
NOTE:
Exercise caution when increasing
the valve response speed. If using a relatively fast valve (1-3
seconds open-to-close), the system may become unstable
with higher valve response speed numbers entered.

TANK ALARM SET POINT:
Use the “+” and “-” buttons
to set the level where the Warning LED starts flashing and
the word “FILL” flashes on the display. Range is OFF or
1-65,535. When the tank
value drops below the
set point, the alarms will
notify the user that the
tank level is low.

AUTO SHUTOFF ON/OFF:
When Auto Shutoff is enabled
(ON) the servo will run toward minimum flow for 4 seconds
any time the system is put in HOLD or all
booms are turned off, or if in AUTO mode and
speed goes to zero. This
feature is normally used
only in Dry Application
systems.

AUTO DELAY TIME:
Typically used when using relatively
slow ball valves for boom shut-off, this feature
delays adjustment of the servo valve until the
boom valves are open. Use “+” and “-” buttons to
