Why is the pressure low on my Franklin Electric SUBDRIVE UTILITY UT3P?
If you're experiencing low pressure with your Franklin Electric DC Drives, first adjust the pressure sensor and check the pump rotation. Also, check the frequency at maximum flow and verify the maximum pressure. A high ambient or drive temperature can also cause the drive to reduce power, leading to reduced performance.
What to do if there is high pressure with Franklin Electric SUBDRIVE UTILITY UT3P DC Drives?
To address high pressure with your Franklin Electric DC Drives, start by adjusting the pressure sensor. If that doesn't resolve the issue, remove the sensor wire at the Input Board. If the drive stops running, the wire may be shorted; verify its condition and repair or replace it if necessary. However, if the drive continues to run after removing the sensor wire, the drive may need replacement.
How to fix pressure fluctuations in Franklin Electric SUBDRIVE UTILITY UT3P DC Drives?
If you observe pressure fluctuations or poor regulation with your Franklin Electric DC Drives, ensure correct pressure sensor placement and settings. The tank might be too small for the system flow. Disconnect power and check the pressure gauge for any drop. If applicable, set the system deeper in the well or tank, and consider installing a flow sleeve with an airtight seal around the drop pipe and cable. If the fluctuation occurs only on branches before the sensor, enable Steady Flow. Finally, adjust the System Response value.
What to do if Franklin Electric SUBDRIVE UTILITY UT3P DC Drives run on and won't stop pump?
If your Franklin Electric DC Drives pump won’t stop running, check the frequency at low flows as the pressure setting may be too close to the pump's maximum head. Verify the precharge at 70% if the tank size is larger than the minimum, and consider increasing the precharge up to 85%. Also, confirm that the system will build and hold pressure. Enabling bump and/or aggressive bump features and increasing the minimum frequency might also help resolve the issue.
How to reduce audible noise from Franklin Electric SUBDRIVE UTILITY UT3P DC Drives?
If you're experiencing excessive fan noise with your Franklin Electric DC Drives, try replacing the fan. If the fan noise is normal, consider relocating the drive to a more remote area. For hydraulic noise, try adjusting the depth of the pump. Ensure the pressure tank is located at the entrance of the water line into the house.
How to prevent RFI-EMI interference in Franklin Electric DC Drives?
To minimize RFI-EMI interference with your Franklin Electric DC Drives, adhere to grounding and wire routing recommendations. If the issue persists, consider using an additional external filter.
How to resolve intermittent operation of Franklin Electric DC Drives?
To resolve intermittent operation of your Franklin Electric DC Drives or pump, wire the drive directly to the pump/motor, bypassing the pump pressure switch.
