User manual CONTAX PVA 5-30

[. . . ] This controller with a 12 to 24 volt input will step the voltage up to 30 volts, the maximum operating voltage of an SDS pump, assuming sufficient input current is available. This manual will show you how to make the connections for your system configuration. Additional options are also explained and the wiring diagrams are given. 12/06/99 2 PVAS-30 SPECIFICATIONS Input Voltage 12-28 Volts (24 Volt Battery System Max) 5 AMPS 10 AMPS 15 AMPS 150 Watts (30V @ 5A) Maximum Output Current Maximum Input Current Maximum Surge Current Maximum Output Power FEATURES 1. ) Current Boosting for matching the load requirements of the pump, in low sunlight conditions. 2. ) 3. ) 4. ) Voltage Boosting for maximum pump output, in good sunlight conditions.

This procedure should be performed with the panels at their normal operating temperature at mid-day and the appropriate DIP switch in the ON position. 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. (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 a battery system is used and the polarity is reversed, damage to the controller will result). Check for proper panel, controller, and/or battery voltage with a volt meter. A quick look at the indicator lights will verify power from the panels going to the controller (red) and power from the controller going to the pump (green). If the over-voltage fault light (yellow) is on, the controller will not turn on. This indicates the incoming voltage is too high for the voltage setting selected on the six-position dip switch. If the red light is on and the green wires at the terminal block and make For an additional pump test, connect LD-, this will bypass the controller direct. light is not, disconnect the float switch sure switch #5 is off and switch #6 is on. a jumper wire across terminals 5 PV- and 6 and will allow the pump to run panel IF BOTH THE RED AND GREEN LIGHTS ARE ON AND THE PUMP DOES NOT RUN Note: To verify power coming out of the controller, connect a DC volt meter across terminals 6 (LD-) and 7 (LD+). (With an ohmmeter set on the R x I scale check between the two pump wires, meter reading should be between . 5 and 50 ohms. If the resistance is higher than this, disconnect the pump at the splice above the pump and check again. ) Note: If no voltage is seen at terminals 6 (LD-) and 7 (LD+) then: 6. Check to see if the water level is above the top electrode when the low water cut-off circuit is being used or below the bottom electrode when the high water cut-off circuit is being used. (To bypass all remote switching circuits, disconnect wires from terminals 1-4 and turn switch #6 on and #5 off). If the voltage setting on the controller is higher than the incoming voltage, the controller will not turn on. (Disconnect wires from terminals 3 & 4 to bypass float circuit. ) 12/06/99 12 EXCESSIVE CURRENT DRAW 1. (See manual section 2. 3d in your pump manual) Check for a locked motor armature.
