SureFire Ag products employ pressure sensors in various places as a way to give you more information to ensure your application and use is in line with what you need. These sensors do not affect application, but rather, give you the information you need to determine if a change should be made to orifices or metering tubes. It is important for the sensors to provide correct readings; if you ever find the pressure sensor on your SureFire product not working use these steps to troubleshoot:
Help! My hydraulic pump won’t turn. If you find yourself in this situation, the SureFire Ag support team is here to help.
There are two components involved in making the hydraulic pump run—hydraulic and electric. There must be hydraulic oil going through the valve block to turn the hydraulic motor to turn the pump. In normal application mode, the PWM signal from the controller energizes the solenoid on the valve block. This causes the proportional valve that is located inside the solenoid to open, allowing hydraulic oil to flow, which turns the pump. If the pump is not turning, we must determine which part of the system is not functioning as it should. Use this guide to help you troubleshoot and check for issues. Refer to the manuals for each controller at the end of the blog for further help.
As 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.
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.
