12. Operation summary
•
Ensure all electrical connections are joined correctly and there are no bare wires.
•
Ensure any output valves fitted to the system are open.
•
Check the DC input isolator is switched on.
The ‘POWER’
LED will illuminate when there is power available.
1.
Press the ON/OFF button to commence operation.
The controller assesses the available energy. If the minimum threshold is met the pump will start
immediately. To check whether the pump is running, press SWITCH to display RPM.
The controller varies the pump running speed and therefore flow output depending on the energy
available. Default RPM is 3600.
2.
Repeated presses of the controller SET button allows the user to cycle through the Voltage,
Pump speed (RPM), Current (Amperage) and Input Power (Wattage) parameters. The LEDs to
the left and right of the display will illuminate to indicate which parameter value is displayed.
The controller employs MPPT and Vector control to achieve maximum efficiency. Solar energy
changes constantly especially on cloudy days. The display values will be constantly changing as
the pump adjusts to optimise the output based on the available input power.
Note that the wattage value indicates what the pump is currently consuming. It is not a measure
of solar array output. It is normal that the values are constantly changing.
3.
Pressing the INCREASE and DECREASE buttons will alter the maximum pump RPM in set
intervals of 4000 / 3600 / 3000 / 2400. The controller will not store this change. Once the power
cycles the controller returns to its default setting (3600 rpm).
4.
If the low water level float circuit shuts the pump down due to a lack of water, the LED on the
controller labelled ‘WELL’ will illuminate. When the
water level rises again the pump will restart
after a 10-minute delay.
5.
Should the output switch circuit (float or pressure switch if fitted) stop the pump running, the
LED on the controller labelled ‘TANK’ will illuminate. Pumping will re
-commence immediately when
the float or pressure switch circuit opens again.
6.
If for any reason the pump has a fault, or the unit is protecting itself, the controller will display
the appropriate alarm code. The codes are listed in Section 10, Page 9.
7.
To suspend operation press the ON/OFF button on the controller.
