Analog Control Curve
RUN Voltage MAX Voltage Function
> 1 V < 3 V Pump at minimum speed.
= 0 V < 2 V Pump is at 1/2 speed.
> 3 V 3 to 10 V Speed is proportional to voltage regulation.
22 - Fault Finding
The pump Status LED will ash red during errors and overload conditions.
The sequence of the ash is determined by the type of the error per the following table.
Error Code (blinks in
1/2 second intervals)
Description Probable Cause(s)
1 blink Locked Rotor Impeller is unable to turn - debris in system
2 blinks Over Current High Motor Load
3 blinks Over Temperature Motor might be faulty or viscous medium is present.
High Motor Load, Water Temperature too hot, Pump running dry.
4 blinks Over Voltage Line voltage is too high.
5 blinks Under Voltage Line voltage is too low for proper operation.
6 blinks Communication Fault
7 blinks Motor Temperature Fault Control temperature near maximum limit.
Control reduces rpm to reduce heat.
8 blinks Staging Fault
