VF2 15 months old never had A problem.alarm 196 coolant spigot failure.It started last week couple times the programmable coolant kind of got lost kept going back up all the way towards the spindle.Now it wont even let me adjust with control.Is this something someone may say is an easy fix.Is there something maybe loose?Just going to have to replace the spigot box?
Thanks Chris

One of the guys here on the forums gave me an old spigot nozzle (PCOOL) that was doing the same thing. This was the older 20 position PCOOL nozzle.

Another guy suggested that I take it apart and check the micro switch that rides on the cam. As it turns out the micro switch was missing some of the steps and caused the problem. I found a replacement micro switch at a local electronics store for around $2.00. I had to modify it a little but that fixed it and it has been working perfect ever since.

There is a post either here or on PM that has the pictures to show what was done to fix it. I don't know if the newer PCOOL nozzles are different or not. But before you throw it away I would check it out.

Let me know if I can be of further assistance. Just send me a PM with your phone number and a good time to call you and I will give you the details.

Thanks John.I have 2 roller switches that both check out ok.I am going to pick them up from grainger and replace them for 7.00 doesnt hurt.The motor works.I manually bring the spigot down it brings it back home then its over,it does nothing after that.Change the switches and see what happens after that I will have to go deeper into the electrical I guess.

Do a search on here. One of the posts has a service bulletin that might help you.

Hi Chris,

It has been a while but there are a couple of parameters and or settings that have to be correct. One of them is setting the number of coolant positions you have but I can't remember what the other one was. It they are not set correctly I can cause issues.

Has anyone changed any of your settings or parameters on or about the time that the alarm occurred.

Just another thing to take a look at if it applies to your situation.

Changed switches still dont work.No settings or parameters were adjusted.I might have to trace the cable back to see if theres any breaks.As soon as I fired up the machine hit the power up button.She XYZ traveled home then the alarm went off It couldnt bring the spigot back up to find home.

Hi Chris,

I guess anything can happen. When I took the cover off my HAAS TM-1P to install the spigot cable I found a ground wire that got smashed during the build process. No big deal but if that happened with the spigot cable time and vibration could take its toll.

Keep us up to date and let us know what you find. Good Luck!

I am wondering if there is A "phasing" on the install.Do the switches need to be timed?Activated together at A certain point. wires are all good.Messing with machine manually brought it all the way down let the machine bring it back up and count the positions and it worked for 10 min,now not so.My HFO went out of buisness customer service was outstanding there,and the techs would have this resolved allready through A phone call.I dont even know if you can get parts in A timely manner here now.

My machine has an 800 number sticker on it to call for Factory Help. I think I would try that option as your HFO went out of business.

There is nothing you can tweek on the inside. There is no phasing either... It's all pretty simple stuff really. Often I see a lot of corrosion that builds up around the black shaft in the back. What gets me is that it worked well up to this point (?) and now it quit.
Disconnect the cable from the unit. You can manually run the unit (by rotating the large spur gear) and check that each lobe of the small cam actuates the counting switch by listening to the click. Also you can check that the homing switch mounted on the casting actuates when the cam pushes back on it. You should also feel more resistance to turning of the large spur gear when the switch engages. If you have both switches working, chances are good that it's not the pcool. Again, make sure that the black shaft rotates freely. You said that the motor moves the nozzle, so the motor is okay.
We have had I/O board issues with regards to the PCOOL circuit. This would require you to have a HFO tech out there... IF and when the tech comes out, have him demonstrate to you that the new board will work.
Let me know if this helped.
