Operator Adjustable Control Features for Custom Operation
(See flowchart on page 14 for steps required to adjust parameters. Parameter list
shows function no., description, range, and factory preset default settings)
F00-RF2 MAXIMUM FREQUENCY (FMAX): Factory preset at 400HZ for Redi-Flo2®
pumps. Maximum frequency is adjustable from 400-100HZ. To adjust maximum
frequency follow the steps on the flowchart on page 14.
F01-RF2 MINIMUM FREQUENCY (FMIN): Factory preset at 25HZ for the Redi-Flo2®
pumps. Minimum frequency is adjustable from 0-100HZ. To adjust minimum frequency
follow the steps on the flowchart on page 14.
F02-RF4 MAXIMUM FREQUENCY (FMAX): Factory preset at 100HZ for Redi-Flo4™
variable performance pumps. Maximum frequency is adjustable from 0.0-100HZ. To
adjust maximum frequency follow the steps on the flowchart on page 14.
F03-RF4 MINIMUM FREQUENCY (FMIN): Factory preset at 25HZ for Redi-Flo4™
variable performance pumps. Minimum frequency is adjustable from 0-30HZ. To adjust
minimum frequency follow the steps on the flowchart on page 14.
F04-ACCELERATION TIME (ACCEL): Factory preset at 5 seconds. Acceleration time is
adjustable from 0.5-10 seconds. To adjust acceleration time follow the steps on the
flowchart on page 14.
F05-DEACCELERATION TIME (DECEL): Factory preset at 5 seconds. Deacceleration
time is adjustable from 0.5-10 seconds. To adjust deacceleration time follow the steps on
the flowchart on page 14.
F06-TORQUE BOOST(BOOST): Torque Boost is used to increase startup torque at low
speeds. Factory preset at zero. Torque Boost is adjustable from 0-30%. To adjust follow
the steps on the flowchart on page 14.
F07-BASE FREQUENCY(MAINS F): Factory preset at 60HZ. Base Frequency is
adjustable to 50HZ or 60HZ. To adjust base frequency follow the steps on the flowchart
on page 14.
F08-MOTOR OVERLOAD(IXT LEVEL): Factory preset at 110%. The Redi-Flo VFD will
trip after 1 minute when output current exceeds 5.5A for Redi-Flo2® pumps and 7.5A for
Redi-Flo4™ pumps. The motor overload is adjustable from 50-110%. To adjust motor
overload trip current, follow the steps on the flowchart on page 14.
F09-UNDERCURRENT(UC ENABLE): Factory preset at (0) disabled. Input under current
detection level is adjustable either to (0) disabled or (1) enabled. To adjust UC level, follow
the steps on the flowchart on page 14.
F10-INPUT UNDERCURRENT LEVEL(UC LEVEL): Factory preset at 30%. Input
undercurrent detection level is adjustable from 10-60%. The input undercurrent trip level is
adjustable from 1.6-9.6A. To adjust detection level, first enable (F09) then adjust level
(F10) by following the steps on the flowchart on page 14.
**The Redi-Flo VFD can protect pumping equipment from damage as a result of “dry
running” at frequencies above 50Hz for the Redi-Flo4™ or above 300Hz for the Redi-
Flo2®.
F11-INPUT UNDERCURRENT RESTART TIME(UC TIME): Factory preset at 1 minute.
Input undercurrent restart time is adjustable from 1-99 minutes. The Redi-Flo VFD can be
set to restart automatically after it has cut out on input under current trip (UC). After a set
period of time (1-99 minutes) the Redi-Flo VFD can be set up to restart automatically or it
can be set not to restart until manually reset. If (F11) is set at zero then there is no
automatic restart. To adjust restart time follow the steps on the flowchart on page 14.
F12-SWITCHING FREQUENCY(MODULATION): Factory preset at 1(7.8 kHz). Switching
frequency is adjustable from 0 (15.6 kHz), 1 (7.8 kHz) or 2 (3.9 kHz). To adjust switching
frequency follow the steps on the flowchart on page 14.
F13-INPUT CURRENT ENABLE: Factory preset at 0 (disabled). Input current is
adjustable from 0 (disabled, 23 A) or 1 (enabled, 16A). To adjust, input current follow the
steps on the flowchart on page 14.
F14-AUTO REFERENCE SIGNAL: Factory preset at 0 (disabled). Auto Reference Signal
is adjustable from 0 or 1 enabled. To adjust Auto Reference Signal follow the steps on
page 14.
F15-NO MOTOR LOAD(UC1): Factory preset at 1 (enabled). No motor load is adjustable
from 0 (disabled) or 1 (enabled). To adjust No Motor Load follow steps on Page 14.
Purging A Well
If the pump is used to purge a well, start the pump at minimum speed and gradually increase
to maximum speed. Do not stop the pump until the pumped fluid contains no visible particles
(to avoid blockage within the pump). Redi-Flo products are not recommended for well
development.
