Oil Head Stuck at 10 Pin Side

[8270tom]

My Kustodian oil head gets stuck on the 10 pin side all the way at the end of travel. What is wrong? It clears up after a while and hasn't done it for a while. Just curious as to what may be failing.

Don't remember if the Kustodian has them, but sounds as if you may have a head sensor going bad.

Replace the 2 white tower relays on the left. Those are your left-to-right and right-to-left relays. It's pretty common for the points to get stuck.

Most likely is what Alex says, but maybe you wanna check the drippad as well....

Are they the 110VAC relays on the left side? Thought they were for forward and reverse drive.

Also I have a Kustodian with the 4 spray heads.

The ones I'm pointing at.

Thanks will follow through with replacement.

How do you remove relay from machine?

[8270tom]

Never mind figured it out, thought had to replace entire green assy with white component.

Did it fix your problem?

[8270tom]

Nope still gets stuck on 10 pin side of machine. Noticed one of the contacts on the white piece I removed had a corroded point. Couldn't remove green section of relay because of a bar holding them all down.

unbolt the din rail (the bar) and slide the green base off. You will need to unbolt and remove the panel from the machine. You will not need to unplug any of the harnesses.

Thanks. Turned out the PLC got nailed. Ordered same after talking to Kegel tech support. Wierd buffer kept going up and down after correcting wiring to tower relays.

I'm confused. was the buffer acting up prior? how did the wiring just messed up?
