The PCA series of pump controllers are a high quality, solid state DC power converters designed as the interface between a Solarjack SDS series pump and a DC power source. The purpose of the controller is to maximize the total daily water output while providing protection for the pump and the DC power source as well as providing interface with other related pumping system equipment. [. . . ] Please refer to the following operational scenarios for configuration options. With switch number 5 in the OFF position, the controller is configured to accommodate a Normally Open (N. O. ) float switch or remote toggle switch. In this configuration the controller will operate as follows: PUMP ON float switch open = water tank low = pump ON PUMP OFF float switch closed = water tank high = pump OFF With switch number 5 in the ON position, the controller is configured to accommodate a Normally Closed (N. C. ) float switch or remote toggle switch. In this configuration the controller will operate as follows: PUMP ON float switch closed = water tank low = pump ON PUMP OFF float switch open = water tank high = pump OFF Water Level Electrodes The water level electrodes interface serve as an automatic system shutdown when properly installed and configured. The PCA series of controllers are capable of two configurations; high or low level shutdown. The high level shutdown is typically used to interface with a water storage tank to achieve the same system control results as a float switch. The low-level shutdown is intended to monitor the well water level and shutdown the system if the water level in the well drops to a critical point. One is for the ground (reference) , the second is for the low-level point and the third is for the high level point. Please refer to the system wiring diagrams and the following operation scenarios for configuration options. With switch number 6 in the OFF position, the controller is configured to interface with electrode water level sensors for a water level HIGH pump shutdown and a LOW water level pump activation. PUMP ON low and high level electrode exposed = water tank low = pump ON PUMP OFF low and high level electrode submerged = water tank high = pump OFF 12/06/99 6 With switch number 6 in the ON position, the controller is configured to interface with electrode water level sensors for a water level LOW pump shutdown and a HIGH water level pump activation. PUMP ON low and high level electrode submerged = well water level ok = pump ON PUMP OFF low and high level electrode exposed = well water level critical = pump OFF 3. 4 Adjustment Procedures The PCA series controllers have several adjustment features. Some are system configuration adjustments are user selectable by a six positions DIP switch located on the face of the controller. These include pre-adjusted DC source selection, remote switch selection and water level cut-off. The remaining adjustments are for input and output voltage fine-tuning that are independently adjustable by high precision multiple turn (brass screw) trimmers. The pre-adjusted DC source selection allows the user to choose the nominal input voltage and basic source configuration. These consist of four pre-adjusted voltage settings consisting of solar panel or battery in nominal 12 volt or 24-volt sources. The first four switches on the DIP switch are used for this selection. For proper controller operation, only one of these first four switches should be in the ON position. Please refer to the chart below for the switch position identification and setting options. In a solar electric application, this procedure should be performed with the solar electric panel at its normal operating temperature at mid-day to match as close as possible the worst case maximum voltage operating point. On a battery source system, it is not recommended to adjust the input voltage set-point. [. . . ] This will bypass the controller and allow the pump to run directly from the DC source. If the DC source is a solar array, the test must be conducted when full sunlight is available for a valid test. RED AND GREEN LEDS ARE ON, YELLOW LED IS OFF AND THE PUMP DOES NOT RUN To verify power coming out of the controller, connect a DC voltmeter across L+ and L-. With an ohmmeter set on the R x 1 scale, check between the two pump lead wires. If the resistance is higher than this, disconnect the pump at the splice above the pump and check again. NO VOLTAGE AT THE L+ AND L- TERMINALS Note: To bypass all remote switching circuits, disconnect all wires from the sensor interface terminal block in the controller housing (the small terminal block) and switch program switches #5 and #6 to the OFF position.
