The guys in VFD, x- formers forum were very helpful in getting the A-B starter modified.
I'm hoping you guys can assist with a hydraulic question I have work this press.
The history on this press is that it's 30-ish years old. The guy that built it is dead so I'm having to rely on you guys for hydraulic expertise [emoji6] .
From the pictures I'm attaching you'll see three cylinders. There is Rexroth valve of some sort that is part of the piping. These three cylinders are piped in parallel.
The wiring is very simple. Up and down pendant with an up/down, EPO switch and power switch.
There are limit switches for up and down too.
My problem today is that I can't get the cylinders to raise or lower. The valve is operating correctly.
What is the blue Rexroth valve do? thanks
We disconnected the piping and reconnected into correctly.
The darn thing just won't budge. I don't know if it has as air lock or something?
The pump is a 20HP.
Any ideas as to what I may be missing?
Thanks,
Tom
