Yet another ATC Fault

Post by jamesgates1000 » Wed 21 Feb , 2018 9:57 am

My Triac has developed another fault on the ATC..

When tool changing the carousel comes in to the spindle really slowly,then gets stuck just pressing against the spindle,I can hear lots of air exhausting from somewhere,which drains my compressor below 100psi, then the compressor charges up and this usually gives it the extra push against the spring to bring the tool to the spindle. Sometimes the tool changer times out.

The cylinder retracts fine,and there are no problems with the up/down or tool release.

When I switch over the pipes to the in/out cylinder,the problem is reversed and the carousel goes into position at the spindle no problems and retracts slowly.

The cylinder was replaced when I bought the machine a couple of years ago, so is fairly new, could this problem be a stcky solenoid valve or is the cylinder likely shot?

It sounds like you have a faulty solenoid.

I guess I can swap over the in/out and up/down solenoids to check this.
