Adjust as needed in the field. Increase the Ctrl
Speed if the pump is slow to adjust. Decrease the
Ctrl Speed if the pump fluctuates and the PWM Duty
Cycle does not settle into a narrow range going
across the field.
RPM Cal
-
15 (for hydraulic pumps equipped with
RPM sensor)
Max RPM
-
500 (Can be set to 550 if needed)
Flow Cal
-
2000
-
most PR hydraulic pump systems
0.6 to 13 gpm flowmeter and larger.
3000
-
most electric pump systems
0.3 to 5 gpm and smaller
(Flow cal number is on serial number sticker on side
of flowmeter)
PWM Max
-
80 to 100
PWM Min
-
20
-
25 for most hydraulic pumps.
5
-
10 for most electric pumps.
Start Boost
-
usually 0. Can be set slightly higher
than normal PWM Duty Cycle for a startup boost.
Open PWM
-
Normally RED. Turn to GREEN if you
want the pump to continue running for product agita-
tion while you turn around. When doing that, enter a
PWM % to set the pump speed for agitation (usually
30
-
40%)
