Polar 115 emc-monitor

I came back from vacation and the cutter is in secondary operation. Found a broken wire going to the scan head. Repaired it. No help. Had an extra scan head that looked new. Put it in still in secondary operation. It scans reference point twice then comes up with no numbers. Otherwise functions correctly. Any help would be greatly appreciated

Hi sir:

Look, for corrosion, bad solder, loose wires, dirty, and finally Faulty Part!!!!!
Let me know, sincerely

Are you sure that you are doing referencing scan correctly?

Turn the power off to the machine while the backgauge is showing motion on the screen. It should bring up a refernce screen when turned back on. It should only take activating the handwheel for it to do its reference procedure.

Sorry for late response. I honestly don’t know what I did to get this going again. I suspect it was a bad connection in the wiring in the back. I fiddled with them and it has worked since. I am now getting a scan reference point only when I am moving the back gauge toward the back. I have replaced the button, the contactor is rather new but I will replace it to eliminate that. I have an extra TAM board and both do the same thing. I have also replaced the LMS with the Welvin reference point encoder. Same issue. When it scans Observe Maintenance Schedule appears. Is this normal ?

Reset your cut counter. That will display the message if its gone past.

Thanks ESPofKC. I will do this.
Found a wire hanging by a thread on the reverse contactor. That fixed the issue
Does anyone have any advice on how to get it dialed in on sizes not being uniform? Such as if you cut 24 then 12, when stacked they will be .010 of an inche to .020 of an inch difference. We deal in a lot of precision work and I would like to get it better.

Calibration is done using the 10 point blue dials on the front of the circuit board. They are meter references. They go from top being meters, cm, mm, dm, downwards. It coincides with the calibration point in your linear scale.
