User manual CONTAX PCB-90

[. . . ] PCB-90 DC SUBMERISIBLE PUMP CONTROLLER USER'S MANUAL PCB-90C SERIES SOLARJACK'S HIGH VOLTAGE PC SERIES PUMP CONTROLLERS SOLARJACK'S PC series controllers are state-of-the-art solid state power converters designed as an interface between a SOLARJACK pump and the DC power source. The purpose of this controller is to maximize the total daily water output while providing protection for the pump as well as the power source. The unique features incorporated in this controller will protect the pump system insuring many years of dependable, trouble free service. When used in a solar panel direct system it provides protection for the pump from over-voltage and over-current conditions and will provide current boosting in low sunlight conditions. [. . . ] Switch #2 in the on position allows the pump to run when terminals 7 and 8 are connected. This is generally used in conjunction with a float switch or a pressure switch which makes contact to run the pump. Switch #2 in the off position allows the pump to run when terminals 7 and 8 are disconnected. This is generally used in conjunction with a float switch which breaks contact to make the pump run. 12/6/1999 4 CONTROLLER ADJUSTING PROCEDURE CAUTION: THIS PROCEDURE SHOULD ONLY BE PREFORMED BY A QUALIFIED SOLAR ELECTRIC TECHNICIAN. THIS PROCEDURE IS NOT NECESSARY IF STANDARD 16. 5 TO 17 VOLT SOLAR MODULES ARE BEING USED. This procedure will not work on a centrifugal type pump such as an SCS submersible. It is only for positive displacement type pumps. The purpose of this procedure is to adjust the voltage of the PV array to its peak power point and thus obtain the maximum water delivery from the pump. This procedure should be performed with the panels at their normal operating temperature at mid-day. (Option 1) For panel voltage adjustment at the maximum power point. With the system installed and pumping water, turn the panels away from the sun until the pump flow rate is reduced by approximately 50%. If this is not possible then shade the panels slightly until you have obtained the same results. This puts the controller in a current boosting mode so this adjustment can be made. Connect a DC volt-meter to the pump side of the controller. (LD+ and LD-) Turn the small brass adjusting screw on the "Panel Voltage Adjusting Pot", located on the front of the controller, until the highest possible voltage is obtained. (If this controller is used on a Jack Pump system using a flywheel, there will be a slight delay from the time you make an adjustment to when a change in voltage will be noticed. ) Return the panels to their normal position. The pump will then operate at its maximum output. 2. 3. 4. (Option 2) For estimated panel voltage adjustment. With the system installed and pumping water, turn the panels away from the sun until the pump flow rate is reduced by approximately 50%. If this is not possible then shade the panels slightly until you obtain the same results. Connect a DC volt meter to the panel side of the controller. (PV+ and PV-) Estimate the proper voltage by multiplying the voltage rating of the panel's times the number of panels connected in series and deduct 20%. [. . . ] Make sure the proper panel voltage selector switch is on for your panel arrangement. (Switches 4-6 on the dip-switch. ) Note: If the incoming voltage is lower than the set point voltage, the controller will not turn on. IF THE RED AND GREEN LIGHTS ARE ON, WITH ALL OTHER LIGHTS OFF, AND THE PUMP DOES NOT RUN: (IN GOOD SUNLIGHT) 12/6/1999 6 4. Check for proper controller output voltage. Connect a DC volt meter across terminals 2 LD- and 3 LD+ on the large terminal block. If no voltage is indicated check the fuse. [. . . ]
