Subject: RE: Clutch Module Configuration Failed


Near Intersection of I-35 & I-90 Southern Mn.
When the system is first powered up and periodically thereafter the system checks the configuration against what sections are electrically present as far as the correct number and location. In your case the configuration should be calling for 10 sections and the clutch module should be detecting 10 sections in the correct locations.

There may have been some confusion when creating the new configuration. If the old configuration is still present I would try it for a test. If it passes this test then there is a problem with the new configuration. The configuration would need to specify that you have 12 rows and 10 sections. It would also need to specify that rows 1 & 2 go together as section 1, rows 3-10 are singles and rows 11 & 12 are together also as section 10. I would double check that first. Maybe try another new configuration and to decide if all the items were answered correctly.

If you get past the clutch test, I would still suggest going through the procedure listed far below to do an actual test on each section.

Another possible area of confusion may deal with the air valve boxes themselves. When you moved the air valve boxes, are you certain that air valve Box #3 (the box to the far right for sections 9 and 10) from the previous install is Box #3 on this install? Since the boxes may have been placed in different places on the new install, this could lead to problems. In your case you need 10 air valves but since they don't make a two valve box, another four valve box is used but only two of its valves are needed. For Ag Leader the unused ones need to be electrically disconnected. This means a wire was detached from air valves 3 & 4 of that box. This would have been done at the time of the original installation. The unused air valves usually remain in the box and can be moved to a different location in case of failure.

Here's one way to check: Remove the covers from all three air valve boxes. Box#1 (Sections 1-4 which is rows 1 & 2, 3, 4, 5) should have wires to all four air valves. Likewise Box #2 (Sections 5-8 which is rows 6,7,8,9) should have wires on all four air valves. Box #3 (Sections 9-10 which is rows 10, 11 & 12) should have wires on the first two air valves but one wire should have been removed from each the other two air valves.

Again Boxes #1 & #2 should have all four air valves connected and used but Box #3 should have the first two still connected and the next two disconnected. The output air lines from the last two should not be used. If you find something different then this will be a problem. If this is the situation you will need to change somethings around.

You could just swap the actual boxes. The first two need all wires attached but the last one on the far right of the planter should only have the first two air solenoid valve connected and a wire removed from air valves 3 & 4 in that box.

If the boxes are already attached it might be easier to work with the wires inside the boxes. That is reattach the wires which were disconnected back to their original locations (important) and detach those same colored wires in the Box #3. I suggest leaving the covers off yet.

Here's how the Clutch Test works and why yours may have failed. Upon startup and periodically at other times, the Ag Leader system checks that there is an EXACT match between the number and locations of sections that it finds in your wiring against the number and locations of sections specified in the configuration. In your case the system should be looking for 10 sections (if the configuration is correct) on the first 10 locations. If it doesn't find this, it gives an error message.

To determine this the Ag Leader system uses a clever approach. Each clutch or in this case air valve solenoid is wired "hot" at all times. The system completes Ground to a section to activate the clutch or air valve to STOP planting. While planting, that ground connection is not held to ground so the clutch engages and 12V could be detected on that line. When performing the clutch test, the system checks to determine which locations report back 12V. If so, it feels there must be a clutch or air valve "out there". The system compares these locations against the configuration and complains with an error message if it does not agree.

The purpose of this test is to warn you that there is a problem with the original install or that something has happened mid season.

Once you get past the clutch test, you should also double check that the air lines go to the proper places. This is because the clutch test can determine if there are the correct number of sections but cannot check your airline routes. Especially with a new install there is the possibility of error. The routing of the air lines can get confused especially when trying to route them through the frame etc.

Here's how I would check this besides visually checking the air lines. With a new configuration the system will assign sections 1-5 to Section switch 1. It will assign sections 6-10 to Section switch 2. This would allow you to flip section switch 1 OFF while leaving section switch 2 ON. Then sections 1-5 should slip but sections 6-10 should engage. Then check them with the switches the other way.

This is fine but I suggest the following for a better test. Assuming you have a 10 sections switchbox, you can go into the configuration and reassign the switches. You can assign switch 1 to section 1, switch 2 to section 2 etc. Then when you perform the section test you can be more assured that the air lines are going to the proper places.

To perform the section by section test. Turn on the system. If the clutch test error message still persists you much correct it. Allow the air compressor to charge the system. With the planter UP, the air system should activate all Tru-Counts to the non planting state and turning the seed shaft should allow all clutches to slip. Then lower the planter or jump the implement switch, disable auto swath so it doesn't get involved and with the Master and all Sections switches UP, all rows should engage. Use a wrench to turn the seed shaft and observe each row unit.

Then with the planter still down, turn OFF Section switch 1 with all other switches ON, this should cause the system to activate section 1 (rows 1 & 2) and allow them to slip. verify this by turning the seed shaft and observing the units. Rows 1 & 2 should not turn, all other rows should turn.

Repeat the process by turning section switches OFF/ON one at a time. If a switch causes a different section to cycle then there is likely confusion with the air lines. If any of this fails or affects a different row you need to investigate.

All of the above may not be necessary but then again it could prevent surprises and delays at planting time.
