Running Indicators and Malfunction Information
The controller has a series of LED lights that indicate the system status. This information helps you
know what is happening with your system.
1. POWER or SYS light: Indicates that power is on to the system.
2. PUMP light: Indicates that power is being provided to the motor.
3. MPPT light: Indicates the solar regulator is operating (flashes).
4. ERR I light: Indicates current error. Examples are when power cables are too small (fix this by
using larger wire cross section such as 4mm² ) or a locked rotor in the pump (fix this by cleaning
out any debris from the pump or drying the pump end out if in water lock)
5. LOW POWER light: Indicates low power input to the controller. Check for shading or bad panel
connections. Can also occur if the speed dial is turned down too low for the pumping head
required.
6. TANK F light: Indicates that a tank full or pressure switch is closed.
7. WELL L light: Indicates that water level has dropped and the low level sensor is open.
