How Can We Help You? Tips from Tech Support

by Oct 3, 2011Yield Monitoring

As harvest season kicks off, Ag Leader’s customer support team is getting several calls about yield monitoring.  Before calling into the tech support call center, there are a few things to keep in mind that can help us more effectively help you. The more information you have ready ahead of time, the faster the call process will take.  For example, we recommend keeping a notebook in the cab of the combine to keep track of the following items:

  1. Display firmware you are running
  2. Elevator Speed
  3. Ground Speed
  4. Header Height indicator changing
  5. Area counting
  6. Green or DGPS icon
  7. Moisture reading correctly
  8. Sensor force readings (Harvest Diagnostics)
  9. Motor current, proximity and relay status (Harvest Diagnostics)

In addition, we have a few common things that you may be able to self-diagnose to save yourself valuable time in the field. One of the most important steps is making sure your firmware is up-to-date. New firmware is usually released twice a year, before the spring and fall seasons.  You will want to ensure your display is running the latest firmware. Below is more information on some other common issues that might come up in the field during harvest:

Map Not Appearing on Screen
Sometimes, it appears that the map is not working on your display although all the other functions seem to work properly.  In this scenario, you may have created a flyer point. A boundary is the ultimate solution, or an easy fix is to clear bounds.  Also, do not change the field on the way to the next location; wait untill you get there.  This will also help eliminate the creation of flyer points.


Yield Not Registering
The most common issue when yield is not registering is your elevator speed. If you are not in the range of 250 -650 RPMs, the yield will not register.  If your elevator speed is okay, the next thing you want to consider is the modules on the CAN BUS.  You will need to look under diagnostics and see if the flow, moisture, and speed modules are communicating.  While looking at the harvest diagnostic page, you can also check to see if the flow sensor is registering grain force.  If the force is zero, either the elevator speed is not in the correct range or the grain is not hitting the impact plate. Next, make sure you are registering a speed on the display and check the primary speed source (in most cases, GPS should be the primary source with a wheel speed as a backup.)  You will also want to check that when the ground speed is registering, the area is accumulating. If area is not counting you will need to look at the header height indicator.  Area is dependent on ground speed, AutoSwath, elevator speed, and header height. Make sure that the stop height is set according to the crop type and conditions.

Moisture Not Registering Correctly
The most common problem with moisture is a blown power fuse. If you are continuously blowing fuses it could be a sign that the motor is getting weak and cannot handle the grain and workload.  The proximity sensor could also be the cause of the moisture not registering correctly. The sensor may have build up on it telling the system the EMU is full of grain. On the back of the proximity switch there is a small setscrew used for adjustment.  Turn the screw clockwise until the motor is running all the time (make sure no grain is present).  At that point, rotate the screw 3.5 turns counter-clockwise.  If the motor continues to run you can completely unplug the proximity switch. Once you have unplugged the switch, if the motor stops running then you know you have a problem with the switch. However, if the motor continues to run then there is likely incorrect wiring or a bad component.

As always, our technical support team is here to help keep you going as you harvest your fields. You can call us at 515-232-5363, and check our extended harvest hours here. Also, don't forget about our tutorial videos available in our Media Center or on our YouTube channel.
