Err
EEPROM Write Error
Data cannot be written to the EEPROM
FAn
Internal Fan Fault
Fan or magnetic contactor failure
FDBKL Wire Break
PID Feedback Loss
The analog input programmed for PID feedback has risen above 21 mA or fallen below 3 mA.
Flow Rate Limit
Drive output speed is being limited due to the Flow Rate (U1-83).
GF
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.
HFB
High Feedback
The feedback signal is too high.
HIAUX
High PI Aux Lvl
High PI Auxiliary Feedback Level
HIFLO
High Flow
High Flow
The meter has detected a high flow condition.
HISUC
High Suction
High Section Pressure
HWL
High Water Level
The “High Water Level” digital input is active (H1-0
o
= 90).
LF
Output Phase Loss
• Phase loss on the output side of the drive.
• Setting L8-07 to 1 or 2 enables Phase Loss Detection.
LF3
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
LFB
Low Feedback
The feedback signal is too low.
LOAUX
Low PI Aux Lvl
Low PI Auxiliary Feedback Level
LOP
Loss of Prime
The pump has lost its prime.
LOSUC
Low Suction
Low Section Pressure
LOWFL
Low Flow
Low Flow
LOWWL
Low Water Level
Low Water Level
