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. [. . . ] 9. 3. 3 Water Sensors and Remote Control The PCA series controllers feature remote peripheral interface functions with easy programming. First is a remote switch interface which supports float switches (storage tank level) or a remote system "ON/OFF" toggle switch. The second peripheral is a water level electrode interface that requires three E-1s brass electrodes. Refer to sample system wiring diagrams as a guide during hook-up. Remote Switch The Remote Switch interface can serve as an automatic system shutdown when used with a water storage tank mounted float switch. It can also serve as a manual system shutdown with a remote system ON/OFF toggle switch. The majority of installations will use this port for float switch interface. Both applications are configured and operate the same way. 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 lowlevel 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. To use this interface, three E-1s brass electrodes must be used. 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 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. [. . . ] Check to see if the float switch, if used, is functioning properly. Check the controller for proper programming and adjustment. If the voltage setting on the controller is higher than the incoming voltage, the controller will not turn on, (See controller adjustment section) Make sure the Yellow LED (over-current shut down) is not on. If it is, switch OFF the system ON/OFF switch, wait a minute and then switch it ON. [. . . ]
