User manual CONTAX PCA 8-60B

[. . . ] When used in a solar panel direct system it provides protection for the pump from over-voltage and over-current conditions or will provide current boosting in low sunlight conditions. This manual will show you how to make the connections for your particular system configuration. Additional options are also explained and the wiring diagrams are given. PCA 8-60B SPECIFICATIONS Input Voltage Maximum Output Current Maximum Surge Current Maximum Output Power 24-80V (Open Circuit) (Four Panels in Series Max) 8 AMPS 12 AMPS 480 Watts (60V @ 8A) FEATURES 1. ) Current Boosting for matching the load requirements of the pump. Surge suppression 4. ) Weather tight cast aluminum enclosure with hinged door. [. . . ] This procedure should be performed with the panels at their normal operating temperature at mid-day and the appropriate DIP switch in the up 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. Turn the small brass adjusting screw on the "Panel Voltage Adjusting Pot", located on the front of the controller, in both directions until the highest possible voltage is obtained. The pump will then operate at its maximum output. 7/19/1999 4 TROUBLESHOOTING PUMP DOES NOT RUN 1. A quick look at the indicator lights will verify power coming from the panels going to the controller (red), power from the controller going to the pump (green) and overcurrent turn-off (yellow). If the red light is on and the green and yellow light is not, make sure the switch is on, disconnect the remote switch wires and electrode wires, if used, and turn switch #5 and #6 off. If the green light is still not on disconnect the pump wires, LD- and LD+. If the green light does not turn on then check voltage on LD- and LD + with a volt meter to confirm no output voltage. For an additional pump test, connect a jumper wire across terminals 5 PV- and 6 LD-, this will bypass the controller and will allow the pump to run panel direct. Note: You must have full or almost full sun for this test to be valid. Make sure the proper voltage selector switch is turned on for your panel or battery arrangement. 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 YELLOW OFF 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. If the resistance is higher than this, disconnect the pump at the splice above the pump and check again. ) 7/19/1999 5 IF NO VOLTAGE IS SEEN AT TERMINALS 6 LD- AND 7 LD, THEN: 1 Make sure the switch is turned on. 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 3 and 4 and turn switch #5 and #6 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. ) 5. (Over-current turn-off) EXCESSIVE CURRENT DRAW (More than the rating of the pump but less than the rating of the controller). 1.
