Operation

Hand/Auto Mode

When powered on, the drive reads the signal on Control Board terminals J10 (Hand/Auto). An open connec-

tion here, or a connected Hand/Auto switch set to AUTO, puts the drive in Auto mode. In Auto mode, the

drive controls the pump to maintain a constant pressure.

If a Hand/Auto switch is connected and set to HAND (closed), the drive operates in Hand mode. Hand mode

runs the pump at a constant speed (default is 60 Hz, shown in the display). This allows the drive to be run at

full speed without a pressure transducer for longer periods of time as in the case of new well development

or system start up. Moving the switch back to AUTO resumes the automatic pressure tracking and control by

the VFD.

System Status

When the drive is controlling the motor and pump, the display is illuminated

and the following information is shown:

Whether the system is in HAND or AUTO mode.

2. Whether the motor is running (RUN) or stopped (STOP).

3. When using a pressure transducer, the system displays the current sys-

tem pressure in PSI.

•

When using a standard pressure sensor, the system displays the current motor speed (in Hz).

When running in HAND mode, the system displays the keypad frequency setpoint.

•

4. When using a pressure transducer in AUTO mode, the motor speed is displayed at the lower left of the

screen. In HAND mode, current system pressure is displayed.

•

When using a standard pressure sensor, this field is not displayed.

5. The lower right of the screen displays output current in Amps.

6. The Bluetooth icon indicates that the VFD is connected to a mobile device running the mobile app. A

thermometer icon displayed at the left side of the screen indicates the drive is in Over Temperature

Fault Detected

If a fault condition occurs, the drive displays the Fault Code and Fault Description.

Several faults reset automatically, displaying a countdown timer until the reset occurs.

Pressing the DOWN button while the countdown timer is active resets the fault immedi-

ately. For faults that require a manual reset, turn off power to the drive (power cycle) and

restart after five minutes.
