Re: EZ Trak Emergency Stop
Good morning, I trust you have a multi meter preferably a DVM. I would check continuity of the overload Normally Closed contacts to make sure that the haven't become resistive since this machine is old and has been sitting dormant. Also the lube oil level switch should be a closed contact if the oil level is sufficient. Since this machine is a 24 vdc control system, All these normally closed contacts better have less than 1 ohm resistance or you will have problems in the E-stop loop. And if memory serves me correctly, the spindle motor has a normally closed thermostatic switch which May be wired into the E-stop loop. I hope this helps. You can drop me an Email to [email protected]
Best,
Rick Macy
Re: EZ Trak Emergency Stop
I was having the same issue, I discovered that the work light was shorting out inside. It is on the same circuit as the e stop on my machine it was blowing the (FU12) fuse and was acting as the Estop. I put new lights in and cut out the factory light and replaced the fuse and it eliminated the issue.
My mill is a Bridgeport VMC 760/22.
Hope this may point you in the right direction.
