System Initial Start Up & Control Settings
APPLICATION SELECTION:
Select either Submersible or Circulating pump to load preset programming. Refer
to the parameter table at the end of this quick-start for presets.
Verify Rotation
Move HOA switch to AUTO position and the VFD will begin to run the motor. Check the output flow and verify proper rotation. If rotation is
incorrect, stop the VFD, turn the VFD power off and wait 5 minutes. Swap two motor leads to change rotation.
The majority of drive setups can be accomplished by going through only one group; the setup [SET] group. This group was designed to
have start-up specific parameters to make start-up easy. Navigate to the SETUP group [SET] by pressing the SHIFT button once from
the main screen. Your display will show SET in the upper left hand corner of the display.
INPUT POWER # OF PHASES:
Default is 3-Phase. Select 1-Phase for single-phase to three-phase conversion
application which will change a motor HP rating setting to 50% of the VFD rating.
RATED MOTOR HP:
Put the motor horsepower rating from the motor nameplate.
RATED MOTOR CURRENT:
Put the motor FLA (full load amps) rating from the motor nameplate.
PRESSURE TRANSDUCER RANGE:
The SET-25 default is for a 0-100PSI transducer. Program the maximum
range of your pressure transducer. E.g. Program a value of 250PSI for a 250PSI transducer.

Advanced Control Features
These parameters are set to optimal and safe default settings for the Submersible Pump application and can be changed
in the field to fit application requirements. You may need to adjust some parameters to provide better control for your
system.
Pre-PID is designed for pump systems with long pipes that require filling pipe at every start. Upon PrePID time delay expiration or when
system pressure (PSI) exceeds the PrePID Exit Level, the VFD will switch to PID control and maintain a system pressure at pressure set-
point.
Note: SET-36 is set to 0.0Hz (Pre-PID is disabled by default) and can be enabled by changing SET-36 frequency.
- Pre-PID Settings (Pipe Fill Mode)
PRE-PID FREQUENCY:
Navigate to SET-36 and put VFD frequency at which drive will run to fill an empty pipe.
Set this parameter for frequency above PID Low Frequency Limit and VFD will run to fill the pipe system for the
time delay set in SET-37 or until pressure exceeds the exit level set in SET-38. Default setting is 0.0 Hz.
PRE-PID STOP DELAY:
This sets the time to fill an empty pipe. Test how much time it takes to fill an empty pipe
during startup and adjust as necessary. Default setting is 180 sec.
PRE-PID EXIT LEVEL:
PSI level above which the VFD will switch to PID control mode to maintain a system
pressure at set-point. Default setting is 25 PSI.

PRESSURE SET-POINT:
Set SET-26 to desired pressure (psi) that VFD needs to maintain. The default is 50PSI
and can be changed to any number within pressure transducer range. The pressure Set-point can be changed in
DRV-00 parameter in remote mode too (in local mode it shows Hz).
Parameter Programming Description
1) Press [MODE] or [SHIFT] key until the desired parameter group is displayed.
2) Press UP [▲] or DOWN [▼] keys to scroll to the desired parameter. If you know the desired parameter number, you can set its number
in the first parameter #00 “Jump code” of any parameter group (except SET and DRV groups) and after pressing [ENTER] key display will
show that parameter.
3) Press [ENTER] key to enter the programming mode, which is indicated by a flashing cursor. Some parameters cannot be changed
during VFD run or fault modes. Refer to the manual to check if desired parameter can be programmed during run.
4) For selectable parameters press [▲] or [▼] keys to change parameter selection.
When programming a numerical value, the value will be changed from maximum to minimum by pressing UP or DOWN key. In order
to change any digit in a numeric value, use the SHIFT key to move the flashing cursor to that digit and UP or DOWN keys to adjust the
selected digit.
5) Press [▲] or [▼] keys to change the digit in numerical parameter value.
6) Press [ENTER] key to finish programming for this parameter. The flashing cursor disappears.

Determine No-Demand Frequency and PID Frequency Low Limit
PID LIMIT LOW:
Turn the HOA switch to Auto position and run system with No demand. When system pressure
is at pressure set-point and frequency is stabilized, add 1Hz to this frequency and set it in SET-27. If system
pressure is above pressure set-point, the first of three conditions for activation of the Sleep mode is met.
For Flat curve pumps Minimum frequency is typically 53-54Hz.
- Setting Sleep Mode
Sleep mode will stop the VFD in no-demand condition when system pressure is slightly above SET-26 set-point and output frequency is
below SET-32 Sleep mode frequency setting for SET-33 Sleep mode delay time. The most critical step is to determine and set a correct
SET-27 PID Frequency Low Limit.
Sleep Boost Mode:
When pump system is ready to go into Sleep mode, it can increase a system pressure by some PSI to prevent
short cycling at low demand changes.
Pipe Leak protection:
Refer to VFD manual for detailed description on Dual Demand and Pipe Leak features.
Pump Speed Limit by Well Water Level:
Refer to VFD manual for details. Requires well level transducer.
SLEEP MODE FREQUENCY:
Set this parameter to [SET-27]+0.5Hz. If VFD frequency is below SET-32, the
second condition for activation of the Sleep mode is met.
SLEEP MODE DELAY TIME:
The SET-33 is a delay time to activate Sleep Mode when other two conditions
are met. If any of two above conditions is off, the Sleep Delay Timer will be reset.
SLEEP BOOST:
The VFD will boost the system pressure by the programmed in SET-34 value before going to
sleep. Default is 3PSI for submersible and 2PSI for Centrifugal pumps.
Program a value of 0PSI to disable this feature.
SLEEP BOOST TIMER:
When VFD is ready for sleep mode it will increase pressure set-point by Sleep Boost
value. When Set-point is met or Sleep Boost Timer SET-47 expires, VFD will activate sleep mode.

UNDERLOAD AMPERAGE:
Adjust SET-78 to 65-70% of SET-03 (FLA) for submersible and 30-35% for
centrifugal pump. Default setting is 0.0 A.
WELL FILL TIME:
If parameter SET-80=YES, SET-81 fill time setting should be sufficient to fill the well before
VFD attempting to start again. Default setting is 60.0 min. If VFD trips again on Under Level fault during restart
attempt, the SET-81 value will be doubled for next restart.
SET
LDT Level
78 0.0 A
Underlevel trip (known as dry well protection) is designed to trip the VFD when the pump motor current draw is less than SET-78 for
SET-77 time delay when VFD output frequency is above SET-76. For submersible pumps it is typically 65-70% and for centrifugal
pumps 30-35%. For the correct adjustment check with motor manufacturer.
Broken Pipe will stop VFD operation if a broken pipe is detected while running in PID control mode to protected from flooding the field.
For trip specifics, please refer to the installation & operation manual

WAKE-UP LEVEL:
The SET-35 is a percentage of SET-25 pressure transducer range. The VFD will wake-up
if system pressure is less than wake-up pressure that can be calculated [SET-26]-([SET-25]*[SET-35]/100). For
100PSI transducer the SET-35 value equals to PSI (2% would be 2PSI).
