Description
Where 'n' is the sensor that has failed to activate. (Not applicable to highest sensor,"1")
The Fail Safe loop in the probe has become open circuit (i.e. >4k ohms)
Circuit Breaker has tripped
Contactor has failed to close (Active input (1) = no fault)
A user definable fault (A link or source required)
Fault input timed out after pump started (Active input (1) = no fault)
A user definable fault (It's a 'Hidden' fault so "Fault" does not flash only "Holdout")
The Power Factor has fallen below a specified threshold
Number of pump starts has exceeded the specified maximum within a 1 hour period
Motor Thermal switch (e.g. PTC Thermistor) has activated (Input inverted)
A user definable fault (A link or source required)
Pump not in Auto mode
A pump based Pulse Start has been initiated
A pump based Pulse Stop has been initiated
Conductive Seal sensor has activated (Sensitivity 40 k Ohms)
In circuit Thermal Overload device has activated
CLS (Capacitive Leakage Sensor) Thermal fault (motor over temperature)
CLS (Capacitive Leakage Sensor) Seal fault (water in oil chamber)
3
FLS (Flygt Leakage Sensor) Thermal fault (motor over temperature)
3
FLS (Flygt Leakage Sensor) Seal fault (liquid in the stator housing )
Flow rate is greater than the specified maximum
Flow rate is greater than the specified maximum
Flow rate is less than the specified minimum
Flow rate is less than the specified minimum
Pump efficiency has fallen below a nominal value by a specified amount
Phase-phase current differs by more than the specified maximum
The incorrect phase rotation (or phase sequence) is connected
