Treshold,start pvm,max pvm???

It has been a mounth and half that i work with my 39m schwing 2000.Overall pump is pretty good thanks Ed.I ve been trying to adapt to the way the boom was programm by the old operator.At first i tought it was me or the cold hydrolic.Now it is much warmer and i still have a hard time being smooth like i used to be with my older proportionnal pump.

Lowering the boom 1 was very gnarly ,i mean nothing on the stick and then bammm!! it drop and pretty much the same with the right slewing and in and out with boom 4

So i decided to ajust the parameter:Treshold,start pvm and max pvm.For the 2 others param i don t know it does!I put at min the treshold Lowered the start pvm to the min and in the end i lowered the max pvm to help me.

Long storie short,i end up slowing the boom to the slowest i think.Thankfully the rabbit speed works.

Last week ,I ve been told to change the solenoids.This morning,I took a look at the controle block and saw that boom 1 and boom 3 solenoids have been replace.I don t know when but they look younguer then the rest.So it put a doubt in my mind .Could it but me that don t find the  right set up or is the Joystick that are getting old,solenoids....VALVES....PUMP......!!

 

I never work with a brand new pump so i don t know how it should work.To what i believe a PROPORTIONAL sould work from 0 to 100% Not only a part of it and trying to figure out what s the best compromise.

Thanks

Tiso

 Try compairing both value settings on the slewing circut. If the swing left function feels good then adjust the swing right value settings to match. I forget the exact number for each function but I think (1+) is swing right (1-) is swing left?.. Be sure to do all six output settings... param/threshold/startPMW/maxPMW/rampUp/rampDown. And dont forget to "Store" the settings you change! This is the only function that (+) and ( -) are equal because gravity is'nt much of a factor.

 Be sure your machine's dead level while you're making or checking the settings. Also be sure the boom is loaded while making adjustments.. If you dont feel comfy doing it on a job with actual concrete in the boom you can also fill the system with water to load the boom.

And of course make sure the pump is dead level while adjusting. Some pumps can be a disaster on the swing when only just a few degrees out of level.. Specialy the ones with the 4 hydrolic cilinders for the swing. (its a rubbish system but more and more used.. )

You might have pulsar issues. If you can't get it set get a couple new ones switch them out.

Make damn SURE you check that the o-rings come out and new ones go in right. Been there, done that !

Hey bud, before you spend the money on new coils, (if your sure thats the problem), take one off your outrigger or water pump valve and swith them. You don't need them proportional. May solve your problem cheaper. But, make sure the o-rings are there!!!!!! As far as adjustment, I can walk you through it if you want to call me. Really, don't mess with nothing but the start pvm and the max pvm. After you get them adjusted, if you watch the handvalve while you are holding steady on the stick, it will pulse quite a bit if your coils are bad. Put your key in and press and hold store for 3-5 seconds and the lights will flash, this will set all settings back to factory settings and you can adjust to what you want from there. My # is 573-216-1124. This is my cell which I also schedule from, so I may have to call back. Remember when your adjusting them, the control has to be on rabbit mode. Hope this helps.

Yes, that way you set to where yours hand valves are all but maxed, (don't max them, needs to be a touch of play or the coils life is cut way down). That will take care of the max pvm, then, with your remote and your boom in the air in an "A" frame, go to the hand valves (which your already there). With the throttle at pump rpm (at all times), slowly ease into a control and watch that lever. If it snaps, back off the start pvm, if it has more delay than you want, bring up the start pvm. All snail is for is cutting the perameters in half. You can do this with an empty boom, but kepp in mind, loaded booms don't react the same but usually you'll be happy.

I didn't start very clearly, sorry. To set the max pvm, with the remote and standing at the hand valves with throttle at pump rpm, max out each control one at a time and check the hand valve for a touch of play. You don't want a whole lot and you don't want no play. You want just a touch of play. Do this with all your boom controls. This way, when you go to snail, it's like bicuits and gravy, you'll love it but at the end of the day, you flip it on rabbit, roll it up, wash er' out, head er' in cause mommas waitin' at home with the beans on the table. (Yeah right but it sounds good anyway)

Make sure to press and release the store after each function is where you want it, so, use the max pvm to max your controls with a touch of play and use start pvm to set where you want the control to start.

I forgot to ask, but does this happen pumping or not or does it just happen when your actually pumping. If it does, you may have an accumulator pump problem. Hopefully, it does it pumping or not.

Ti-So. Yes make sure you are in Rabbit while adjusting everything. You should be at operating rpms and your oil should be at normal operating temperature which Schwing says is 50 degrees C. use your cocking block to pre heat your oil. In your case, it sounds like you need to lower the start pvm if the boom all of a sudden takes off. If you have messed with the threshold, ramp up, and down, i would restore back to factory settings and just re adjust the min and max pvm. I was always taught that the start pvm should be where the boom first starts moving and max pvm is max travel with the hand valve still visibly pulsating. A word of advice, be careful that you are adjusting the function you wish to adjust because it can get confusing with each function being numbered with a number and a +/-
