Ok this is Off Topic, but there is a PLC controlling the solenoid... So maybe that counts for a PLC forum.
Forgive me for my lack of hydraulic knowledge and terminology... I'm an electrical guy.
Our customer has hydraulic directional control valve (double solenoid) that has run fine for the past 7 years. A few months ago I was called in and found the one solenoid was burned out. They replaced the failed assembly and proceeded fine until yesterday, it started blowing fuses again... The very same solenoid was burned out. (This machine has around 20 solenoids.) Replaced the valve assembly again, but now it keeps blowing fuses every couple hours.
The DCV has been replaced each time with the same unit (is a Parker D1VW001CNYCF4) Also the fuse type & size has always been changed properly.
Anybody have any ideas what could be causing this?? Is it possible something in the hydraulic system could be destroying this solenoid??
Just grasping for clues and I know there's lots of knowledge here so thought I'd give it a go...
My next try is to put an RC suppressor on the solenoid. None of the other solenoids have them, but I'm hoping it will dampen the problem.
