Hello all, first post here so apologies if I have this in the wrong place or if this has been touched on elsewhere. I tried searching for similar posts and while I learned a good bit, I think I could still use a bit of help.
So today I messed up by accidentally running our small shop that is set up for US 60Hz power off a generator outputting 60Hz for probably 30 minutes. We were lucky and we came out of it pretty unscathed. The biggest loss waas the Digital Read Out (DRO) for our mill which didn't survive. It would be great if I could fix it, but at this point I'm just trying to figure out what component(s) need replacement or if I need to order an entire new setup. I'll try to summarize what I know/have found out. Feel free to tell me I am terribly wrong on something as I haven't had much electrical experience since I graduated and as an ME we only covered pretty rudimentary mechatronics/ESys material.
The DRO consists of:
The AC Adapter has the following information on it:
Input: 120VAC 60Hz 200mA
Output: 7.5VAC 1000mA
(I don't want to violate any forum rules but I can link to the exact brand/model if that would help and isn't against the rules.)
As far as I know, the voltage and amperage should have been correct with the only issue being the wrong frequency.
I know the AC Adapter is likely fried/overheated since it was warm to the touch for probably a good 10 minutes after unplugged. From what I've read it is common for newer adapters to lack a margin of safety large enough to handle the wrong frequency, especially if it is marked with a VAC and specific frequency like this one is. If it is all that was damaged I would be very happy though.
I have no idea on the status of the display/control panel. This is where the bulk of the circuitry is and well beyond my abilities to repair if it has more than minor damage. If the damage stops there, though, then it will still save me from having to replace the entire assembly.
I was hoping the sensors would be purely resistive and thus OK, but after looking up optical encoders, it doesn't look like that is the case (however, I have zero familiarity with the working of this type of sensor beyond a little googling). If the damage has gone this far, I will simply have to repurchase the entire system.
Thanks in advance for any help and let me know if there is anything else I should look into/provide!

The DRO consists of:
- The display/control panel
- Three position sensors (X, Y and Z axes, they are optical encoders set up on a rack & pinion)
- The AC Adapter
