Why does my Franklin Electric submonitor Protection Device have False Starts?
False starts in your Franklin Electric Protection Device can be attributed to a few issues. Chattering contacts may be the cause, so check and replace them. Loose connections in the motor power circuit can also lead to false starts, so tighten any loose connections. Additionally, inspect and repair any arcing contacts.
How to fix Phase Reversal in Franklin Electric submonitor Protection Device?
If you're experiencing phase reversal with your Franklin Electric Protection Device, it indicates an incoming power problem. Check the incoming voltage phase sequence to resolve this issue.
Why does my Franklin Electric Protection Device show Overvoltage?
The reason your Franklin Electric Protection Device is showing overvoltage is likely due to an unstable power supply. To resolve this, ensure the power supply is stable and not fluctuating.
Why does my Franklin Electric submonitor show Undervoltage?
Undervoltage issues with your Franklin Electric Protection Device could be due to poor connections in the motor power circuit, so inspect and rectify any poor connections. Alternatively, an unstable or weak power supply might be the cause, so stabilize the power supply to avoid undervoltage.
What causes Overrange in Franklin Electric submonitor Protection Device?
Overrange issues in your Franklin Electric Protection Device may arise from a wrong motor voltage or SFA setting, so verify and adjust the motor settings. Excessively high line voltage or motor current can also cause overrange; reduce the line voltage or motor current accordingly.
What causes Unbalance in my Franklin Electric submonitor Protection Device?
Unbalance in your Franklin Electric Protection Device can stem from a few key issues. A phase loss could be the cause, so investigate and restore any lost phases. An unbalanced power supply can also lead to this problem; check the power supply balance and adjust as necessary. Lastly, issues with an open delta transformer can cause unbalance, so examine and repair any problems with the transformer.
What to do if my Franklin Electric submonitor indicates Underload?
If your Franklin Electric Protection Device indicates an underload condition, consider the following potential causes. The SF Max Amps setting may be incorrect and needs adjustment. Over-pumping of the well could be the issue, so inspect and adjust the well pumping operation. A clogged pump intake, closed valve, loose pump impeller, broken shaft or coupling, or a phase loss can also cause an underload. Clear any clogs, open any closed valves, tighten the impeller, repair or replace the shaft/coupling, and investigate/restore any lost phases.
Why is my Franklin Electric Protection Device overheating?
Several factors can cause your Franklin Electric Protection Device to overheat. High or low line voltage can contribute, so check and stabilize the line voltage. An overloaded motor can also lead to overheating, so reduce the motor load. Excessive current unbalance, poor motor cooling, high water temperature, and excessive electrical noise from nearby VFDs can also be culprits. Balance the current, improve motor cooling, lower the water temperature, and reposition the VFD to reduce electrical noise interference.
