Title: Problems with Accuset 2, and one other question about my WM
Post by: RPowers on November 20, 2016, 02:24:40 PM
I have been loving the upgrade from  my LT28 all-manual mill to the decked-out LT50 this year, especially the setworks system. I am having a recurring problem/glitch on the Accuset 2 system and was wondering if it has happened to anyone else.  3+ times a sawing day the program features will lock up. I can move the head up or down in manual mode, but none of the Auto-Up/Down or Pattern features will do anything at all. I have to shut the mill down causing the software to reboot and then everything is fine, until it happens again. I haven't noticed anything in particular that triggers it. Often it happens when I have used the Auto-up feature, but not 100% of the time, just more often than the other programs. I called WM and they sent me a drive with the newest software revision (which happened to be the same on on it already) and I reflashed the system with that. No change, problem still just as prevalent, and getting me irritated at having to shut the entire mill down just to reboot the software several times a day.

Any ideas on this?

On another topic, what is the purpose of the little blade enveloping section on the idle-side blade guide weldment? I can't find anything on it's purpose or how to adjust it yet there are several set screws built into it. I have a red arrow on the diagram below showing the portion I am referencing. I want to change my lube drip over to a wiper system and was eyeing this little gem as a possible location for that unless it has some other important fuction that WM doesn't note in their books.

Can't help you with the Accuset issue, but the other thing is where the nozzles and tube connect when you have the Lube-Mizer option.

Im only guessing here on the accuset 2 thing but it sounds like a loose wire somewheres. Check your up/down motor connections and your  up/downdrum switch is all lubed up with the special grease and the connections are tight. My accuset 2 goes stupid if my battery voltage gets low. If you are using alot of hydralics at idle, your battery voltage may have dropped. I replaced the pulley on my alternator to a smaller one to speed it up as my battery was always suffering. Im still stabbing in the dark here. Good luck

On the idle side block, most of the set screws hide drilled holes and the top rear most one is where a fitting goes for the lube-mizer. You'd have to plug up the bottom section if you used drip feed since it'd just drip out the bottom hole.

And we have a weird issue with our LT70 Super where it fails to reach target and instead keeps dropping. This only happens daily, so I haven't tried to fix it yet. My shot in the dark guess is that the power supply needs to be filtered, but I don't know what's the best away. I'm assuming just hang a big capacitor off the alternator leads since that's the noisest part of the mill electrically. I'll just have to try and see.

Just a question; are you using your Accuset while the power feed is in motion, either forward or backwards, or engaging the power feed while the head is still dropping.  I am asking because that additional power draw could be enough (too much) and could be an indicator that you have a loose/bad connection somewhere causing a power drop to the Accuset.

RP,

   Not sure if it could be the same thing but not long after I got my LT35 the simpleset would stop working. The manual mode worked fine but I could not turn the SS off to reset as I'd move the log/cant as I remember. I could just toggle the switch enough to shut off the panel but not stop the engine from running and it would reboot. I called WM and they said possible moisture problem and they sent me a new touch pad. When it arrived I unplugged the old one and plugged the new one in and has worked fine ever since. The touch pad had 5-6 little metal dots as I remember that make contend when pushed.

My accuset II does that all the time.  A WM tech told me it was a failsafe and that if it didnt lock up the head would take off.  It is annoying...never got it to stop.

Check all of the wire connections connecting the accuset to the lower control box.   Check both ends of each wire and make sure they are all connected tight.   It only takes a small amount of voltage drop to screw up accuset and a loose connection can cause it.

Mine does this occasionally.  I have been able fix it by unplugging and plugging in the Accuset cable in the back of the unit a few times.  I believe its a loose connection, and causes a low voltage trip.

Great info you all thanks for the ideas. I will check all the connections first thing in the Accu2 setup and at alternator. If this persists I will wire a momentary switch in the accuset power lead so I can shut it down and reboot w/o turning off the engine

Check your grounds, they are the other side of the power and if slightly corroded they will raise havoc.

Hello,
   Accuset 2. Issues can occur if you rush the set. It is accurate, so if the program does not reach the mark and you make another command the program will abort. Sometimes it will go into manual mode and you need to turn off the ignition key and restart the program. It does seem to be intermittent.
Other things you can check, some have commented on these, ground, battery voltage, connections with the cables from the transducer to the H bridge. Also check the scale mounting to make sure it is not loose. There are two nuts I have seen the inside nuts come loose.

Not sure if I explained this well enough. So ask more questions.

Changing PID values can be done. But please document the factory setting before changing. So you can go back to factory setting. Only change one PID value at a time. You can always reset the Accuset but then you need to calibrate the head and put the Gradient number in.
I would recommend not everyone change the PID values. 


Hope this helps.

Marty

We found a loose connection where the LT50 cat track connects to the frame assembly near the axle.  The intermittent connection made phantom-like up/down decisions.  Took it apart and cleaned it up.  No further problems.  That LT50 is an amazing machine, isn't it!

4x4.\, this is not a fail safe. Whom ever said this misspoke.

RPowers, the issue you are having is called an "ABORT". This happens when you have not fully reached the target. Here are some things to do:
1. To make sure you do not have a "BUG" in the system, do a factory reboot.
     a. Write down what the gradient number you hve stored in the front panel.
     b. Put the head at 12" on a downward tooth above the bedrail and turn the key off.
     c. Hold down the toggle button (1/2 black and 1/2 white) and turn the key on. You will be asked do you want to reset to default. Press yes.
     d. Re-entered the gradient number.
     e. Re-entered the 12"
2. Saturate the up/dn mast with transmission fluid only.
3. Verify the up/dn chain is adjusted properly. To much slack can effect the accuracy.
4. Make sure the head drops past the mark and comes back up. The needs to happen for the Accuset II to function properly.
5. If all this is good, increase the UP MIN by increments of 2 and see if you can stop the locking up.

Sparks, the guy who told me that is no longer with WM.  I might have relayed what he told me wrong, possibly.

Today, my head did that thing where I hit the drum switch to bring me to the next cut and the head got close to it and started jumping up and down in maybe 1/2" increments until it timed out and stopped it.  I'm glad I noticed it and could stop the head in time before I jammed the blade in the wood.

Mine has done that a few times as well.

Thanks @Sparks and all who have commented. I haven't had a chance to look for a loose connection yet but have been trying not to push the machine while the Accuset is still "thinking" and have had less aborts.

The head hunting could be caused by:
1. A loose/defective transducer cable.
2. An up/dn chain with more than 1/2" play. Raise head to 30" to check.
3. Vibration on the transducer. Only if it hunts with the engine running. While it's hunting grab the transducer rod and see if it stops.
4. An up/dn brake that is not holding the head once it stops. Remove the brake and see if the center hole is damaged.

Thanks Sparks, preciate it.  Will look into that tomorrow.
