Contax PCA 8-60B Operation & User’s Manual

converters designed as the interface between a SOLARJACK SDS series pump and the DC power source. This power source may be solar panels or batteries. The purpose of the 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 each controller will protect your pumping system allowing it to provide you with 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 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.

WIRE TERMINAL DESCRIPTION WITH DIP SWITCH #6 OFF: High water cut-off (tank fill-up) 1) LO LOW WATER LEVEL SENSOR turns the pump off.(Mount an E-1s electrode 2" above the ground sensor.) 2) HI HIGHWATER LEVEL SENSOR turns the pump off.(Mount an E-1s brass electrode at the desired turn-off point.) WITH DIP SWITCH #6 ON: (Low water cut-off) 1) LO LOW WATER LEVEL SENSOR turns the pump off.(Mount an E-1s electrode 2” above the ground sensor.) 2) HI HIGH WATER LEVEL SENSOR turns the pump on.(Mount an E-1s brass electrode below the static water level at the desired turn-on point.) 3) GN GROUND OR COMMON WATER SENSOR must be in the water RS- at all times. (Mount an E-1s electrode 2" above the pump.) 3 & 4) REMOTE ON-OFF CIRCUIT is used to turn the pump on and off from a remote location. (Connect the two terminals to turn the pump off, if switch 5 is off. Disconnect the two terminals to turn the pump off if switch 5 is on.) 5) PV- NEGATIVE WIRE from the PV array. 6) LD- NEGATIVE WIRE to the pump or load. 7) LD+ POSITIVE WIRE to the pump or load. 8) PV+ POSITIVE WIRE from the PV array.

The PC series controller has an easy to adjust pre-set voltage selector switch. This six position selector DIP switch is located on the face of the controller and has three preset voltage settings for various panel and battery arrangements. Please refer to the chart below for the switch position for your system. Only one of the first 3 switches should be in the on position at one time. These preset voltage settings will work with most standard solar modules on the market. If you need to change these voltage set points the "panel voltage adjusting pot" will allow you to do so. (Refer to the controller adjusting procedures below). CAUTION: Improper adjustment of this pot will decrease the flow rate of the pump or will not allow the controller to turn on. The controller is designed to hold the voltage constant around the maximum power point of the panels. The set points available on this controller are as follows: Switch No. Used For Voltage Set Point 1. 30 Volt Panel Direct 26.0 2. 45 Volt Panel Direct 41.O 3. 60 Volt Panel Direct 54.0 4. For Factory Use Only 5. Remote Switch Logic 6. Electrode Logic 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 and the appropriate DIP switch in the up position. 1. 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. 2. Connect a DC volt meter to the pump side of the controller. (LD+ and LD-) 3. 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. 4. Return the panels to their normal position. The pump will then operate at its maximum output.

1. Check wiring diagrams for proper connections. 2. Check for proper panel voltage with a volt meter. 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 over- current 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. 3. 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 + . If 12 volts or more is coming out then: 1. Check the splice above the pump for proper connections. 2. Check for a broken wire leading to the pump. 3. Check for an open motor winding. (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.)

1 Make sure the switch is turned on. (In the up position) 2. 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). 3. Check the controller for proper adjustment. If the voltage setting on the controller is higher than the incoming voltage, the controller will not turn on. (See controller adjustment section.) 4. Check to see if the float switch, if used, is functioning properly. (Disconnect wires from terminals 3 & 4 to bypass float circuit.) 5. Make sure the yellow light is not on. (Over-current turn-off) EXCESSIVE CURRENT DRAW (More than the rating of the pump but less than the rating of the controller). 1. Check wiring diagrams for proper connections. 2. Check for skinned wires or faulty underwater splice. (See section 2.3d in your pump manual.) 3. Check for a locked motor armature. (With the pump out of the well, bypass the controller and connect power directly to the motor leads. If the pump still does not run and the current is over 1.5 amps, the pump is in a locked rotor condition and must be repaired.)
