Sleep Frequency
In Hz. This parameter value is added to the frequency set by the parameter 1.1.1
MIN FREQUENCY. The combined value is the frequency at which drive will
enter sleep mode when GPM is controlled at the set point.
Submersible Pump
ENABLE THIS FEATURE WITH SUMBERSIBLE PUMPS. Frequency will ramp
from stop to the value set by parameter 1.1.1 MIN FREQUENCY in one second.
Submersible pumps suffer damage to the thrust bearing if operated below 30 Hz
for more than 1 second.
Overcurrent Limit
Disables manual operation of the drive through the keypad.
Sleep Frequency
Setting for motor overload protection, Trip Class 10 curve.

DESCRIPTION
Run Suction Pump Setup
Wizard?
Press the “Enter” key to go through the wizard. Press “Home” key to return to
Home screen.
Max Analog Sensor Range
This value should be set to the maximum value of the 4-20 mA transducer being
used for suction pressure control. i.e. if the transducer has a range of 0-150 psi,
the parameter should be set to 150.
Analog Setpoint 1
In psi. Used only for transducers wired to 1_2. The pressure setting where any
value lower will trigger a fault.
Low Pressure Fault Level
In psi. This is the inlet pressure that will signify a loss of suction pressure and
trigger a fault.
Suction Pressure Time
In seconds. The time at which the pressure must remain below 1.4.40 Low
Pressure Fault Level before triggering a fault.
Submersible Pump
ENABLE THIS FEATURE WITH SUMBERSIBLE PUMPS. Frequency will ramp
from stop to the value set by parameter 1.1.1 MIN FREQUENCY in one second.
Submersible pumps suffer damage to the thrust bearing if operated below 30 Hz
for more than 1 second.
Disable Manual Mode
Disables manual operation of the drive through the keypad.
Overcurrent Limit
Setting for motor overload protection, Trip Class 10 curve.

DESCRIPTION
Run HVAC Setup Wizard?
Press the “Enter” key to go through the wizard. Press “Home” key to return to Home
screen.
Speed Reference
Select whether the speed reference will be a 4-20 mA signal or a 0-10 VDC signal.
Min Frequency
In Hz. The lowest frequency the drive will operate the load at. If submersible pump
is chosen, the drive will ramp from stop to the value set by parameter 1.1.1 MIN
FREQUENCY in one second.
Max Frequency
In Hz. The maximum frequency that the drive will operate the load at.
Disable Manual Mode
Disables manual operation of the drive through the keypad.
Overcurrent Limit
Setting for motor overload protection, Trip Class 10 curve.
Motor RPM
Set the nameplate RPM rating of the motor.
