SureFire Tower 110 Electric Pump System

SureFire Tower 110 Electric Pump SystemAs you begin to get your systems in place for a successful spring planting season, some of the most common questions the SureFire Ag team receives are about electric pumps.  In order to save you time and frustration, this blog will serve to answer some of the common questions.

Whether you are using a SureFire Ag PumpRight or a Tower Electric Pump, frequently asked questions and concerns about pumps include:

EPD Flashing Light Error Codes
EPD stands for electric pump driver. It serves as the control system and operating system for your pump. If your system is operating properly, there should be a steady blinking light in the middle of the display when pumps are off. If the LED light is flashing four times, then pausing, the EPD has tripped due to a low voltage condition. Unplug the Power Supply to the EPD to reset. If the condition persists, check Power Supply cables from battery to EPD to ensure a solid connection and viable electrical path. It is best to check the voltage under load. Voltage may appear normal when the pumps are off, but if there are connection or harness issues there may not be sufficient voltage under load conditions. There should be 11-12 volts at the point where the EPD connects to the battery power harness; lower voltage could result in a flashing light error. If the voltage drops too much under a load, check all the pins and connectors for something that might be loose, corroded, or not making good contact. Be sure the power harness goes directly to the battery, as power strips may not be able to provide the current needed to run the electric pumps. Be sure the harnesses have wires of sufficient size. 6 AWG or 8 AWG will be needed, especially for longer runs. Also, when testing the system, be sure the tractor is running. The pumps will draw a battery down quickly and encounter low voltage problems.
