1LH - Quick Start Guide Configuration
(Single-Phase Input)
1LH QUICKSTART, Revision 002
Typical Configuration:
Analog Constant Pressure Setup
Setup Constant Pressure |
Yes (Enter) No (Home) |
- On start, use the arrows to toggle to “RUN CONSTANT PRESSURE WIZARD?”. Press ENTER key to proceed.
- “MAX ANALOG SENSOR RANGE” - Set the psi range of the 4-20mA psi sensor. Default is 150 psi. Press ENTER to proceed.
- "ANALOG SETPOINT” - Determines the pressure you want to maintain. The factory default is 50 psi. Use the arrow keys to change if desired. Press ENTER to proceed.
- "SUBMERSIBLE PUMP” - This parameter sets the ramp profile for a submersible pump. “Yes” - ramps to 30 HZ in the first second to prevent excessive wear on the thrust bearing. “No” - The frequency will increase in a linear fashion from zero to max frequency. Use the arrow keys to toggle between the two settings. Press ENTER to proceed.
- "DISABLE MANUAL MODE” - The “Yes” value allows you to disable the MANUAL run mode. “No” allows you to run the VFD manually on/off max frequency.
- “OVERCURRENT LIMIT” - Setting for motor overload protection (full load or service factor amp rating for the motor) using the arrows to toggle. Press ENTER to proceed.
- Press the RUN/AUTO button to start the pump.
- Motor rotation must be verified upon completion of setup.
- If the VFD is not going to sleep, first check for leaks. If no leaks are present, increase the “Shutoff Frequency” under “Constant Pressure Parameters.”
- Set pressure tank psi to 70% of VFD psi Setpoint.
- Any settings can be modified after the initial setup completes. For full listing of available parameters, please refer to the product manual.
Alternative Configuration:
Speed Reference
Overcurrent Limit |
110.0 Amps |
- On start, use the arrows to toggle to “SPEED REFERENCE?”. Press ENTER key to proceed.
- "SPEED REFERENCE” - Select how speed reference is controlled between Start/Stop, 4-20mA, and 0-10 VDC using arrows to toggle. Press ENTER to proceed.
- "MAX FREQUENCY” - Set maximum frequency/ the target of start- up ramp. Press ENTER to proceed.
- "DISABLE MANUAL MODE” - The “Yes” value allows you to disable the MANUAL run mode. “No” allows you to run the VFD manually on/off max frequency. Press ENTER to proceed.
- "OVERCURRENT LIMIT” - Setting for motor overload protection (full load or service factor amp rating for the motor) using the arrows to toggle. Press ENTER to proceed.
- "MOTOR RPM” - Use the arrows to adjust the RPM rating of the motor. Use the enter key to move from left to right. Press ENTER to proceed
- "UNDER CURRENT” - Minimum current allowed before unit trips. Toggle over to set the value—typically 70% of the motor’s full load amps. For best results, consult the motor manufacturer. Press ENTER to proceed.
- Press the RUN/AUTO button to start the system
- Typical connections: Start/ Stop to AUX1 and COM, 4-20mA analog input to l1+ and l1- or l2+ and l2-, 10 VDC input to 10 V, V IN and COM.
- Caution: Introducing voltage to AUX connections will damage the control board. Any such damage is not covered by the product warranty. Refer to the manual to confirm proper input connections.
