EEPROM Write Error
Data cannot be written to the EEPROM
Internal Fan Fault
Fan or magnetic contactor failure
PID Feedback Loss
The analog input programmed for PID feedback has risen above 21 mA or fallen below 3 mA.
Drive output speed is being limited due to the Flow Rate (U1-83).
Ground Fault
• A current short to ground exceeded 50% of rated current on the output side of the drive.
• Setting L8-09 to 1 enables ground fault detection.
High Feedback
The feedback signal is too high.
High PI Auxiliary Feedback Level
High Flow
The meter has detected a high flow condition.
High Section Pressure
High Water Level
The "High Water Level" digital input is active (H1-0o = 90).
Output Phase Loss
• Phase loss on the output side of the drive.
• Setting L8-07 to 1 or 2 enables Phase Loss Detection.
Power Unit Output Phase Loss 3
• Phase loss occurred on the output side
• Setting L8-78 to 1 enables Power Unit Output Phase Loss Protection
Low Feedback
The feedback signal is too low.
Low PI Auxiliary Feedback Level
Loss of Prime
The pump has lost its prime.
Low Section Pressure
Low Flow
Low Water Level
