Mult-Function Joystick on NH L220

I have a 2012 NH L220 with high-flow hydraulics & the 8-function joysticks. But not the enhanced (higher pressure) high flow. The 8-function joysticks are pictured below:





So far, I've only used the 1/2" std. flow with the proportional control on the right stick. I understand that to use the 5/8" high flow, I would need to hook to the 5/8" couplers, set the panel switch to high flow, & then still use the proportional control on the right stick to control it.

But, I'm a little unclear on how to use the Multifunction buttons (2 on the left stick, 2 on the right stick). The Operator's Manual is very vague on their use. Clearly, in order to use them, the attachment must be plugged into the 14-pin multifunction electrical outlet under the aux. hydraulic couplers on the left arm. The symbols on 3 of the multifunction buttons are hydraulic cylinders, but it seems that they must be controlled by electric servos signaled thru the multifunction outlet. I suppose the exact nature of what these buttons control depends entirely on the type of attachment.

Can someone give some examples of what kinds of attachments would use these multifunction buttons & the multifunction outlet to be controlled?? And how they might be hooked up??

Does anyone have a NH or Case (alpha series) with this same setup? And have or know how to use such attachments/functions?? How about KSSS??

Not a NH machine but what i have been reading on my machine is.One of them is for one way hydraulics(Hammer) then other is for two way cylinder attachment.Mine also has a couple more switch that you need to move to switch it back and fore for one way use and two way use.

Maybe someone else can answer like Shane.Good luck

Mulcher with the extra coupler to open the door.Big couplers for high flow.Case drain.

Harley rake one for the drum, other for the angle.Maybe like Bobcat grader attachment which needs extra functions.Shane your man.

So far the only attachment that I have that has taxed the CNH deluxe control handle package has been the Bobcat grader attachment. It would not be an issue if I did not have the 4K psi high flow system. The enhanced high flow system uses one of those aux buttons to control that high flow function. That means I have one less switch to use for the grader which is a switch intensive attachment. Certainly I think CASE could have come up with a better way. If you have E-highflow your using attachments that require a lot of switches and using one to activate the system is pretty poor setup, the dealer was able to make it all work. We used a Skid Steer Solutions pig tail, but the ends had to be changed on the pigtail to fit the BC grader. So it was not easy nor cheap to make it all work but it does. My SV300 has the normal high flow so it actually works better on the grader than does the TR320 with the enhanced high flow (it works better from a plug and play perspective, but obviously a CTL works better on a grader than does a wheeled machine). The BC grader uses one switch to utilize the sideshift, one switch to change the angle of the mold board and two switches to change the elevation of the mold board (each side is independently controlled). So you need 4 switches that are open to make it work optimally. The roller switch has to be locked in the on position and than all the other switches are operational.

Very interesting...thank you for the explanation & examples.

To answer part of your question, once you actuate the auxiliary hydraulics to send power to the attachement, the electrical controls can then be used to determine where that fluid goes. This is decided by the valvebody on the attachment. Sometimes the flow will automatically run a motor or something and the electrical controls will divert fluid to other functions.

The 6-way dozer blade works this way.Angle and tilt goes through a divert valve.You have to hold one of the button down for angle and also the tilt off the foot pedal.Just can't do both at the same time .You have to let off the button between the two functions.

I thank everyone for your responses...I now understand the multifunction aspect much better.

Now, for another question, slightly off topic, but still re: my NH L220...pay attention KSSS, this might be very close to your Case experience...

Almost the last annoying thing that I haven't been able to "fix" on my 2012 NH L220 SSL is that the sliding side windows are VERY hard to open & slide, particularly when it's cold. I like to open them a little to let moisture out...I've tried loosening up the window molding knobs a little, & spraying silicone lube in the tracks, but they still are a PITA. The window looks like this:





Anybody got any suggestions??

Bake sure you read and understand the instructions for removing windows, then remove the glass and clean the track. After cleaning the track reinstall the windows making sure the lower slide rail is installed correctly.
The lower slide rail, if memory serves correct drops down a little bit to allow the glass to drop down to facilitate the removal. If the lower rails are not installed correctly the glass panels will bind. If the lower track is filled with dirt and debris the glass will bind.
You owners manual usually located behind the seat somewhat explains the procedure to remove the glass. Good luck.

Thanks for the advice, PopSiclePete....I know the slides are clean, but when the weather warms some I will take your suggestion & remove the windows per instructions, see what's going on, & re-install them. Too cold right now...come on Spring!!!
