Meanwell Driver adjustment help

thanks 2Quill, that was a big help. Still having issue with one array.
Any ideas regarding post #17.
Is the flashing some kind of protection mode?

Double check all of your connections to make sure you have the proper polarity on every led. Double check your wires going to the audrino. Have you tried un plugging the driver?

will do in the AM.
I'm shot. Been @ it all day.
I have unplugged/plugged driver.

thanks again

I would suggest going over the array looking for wiring/soldering problems. Make sure orientation is correct on every LED. Make sure every LED works with a diode tester (sounds like you already did this). Make sure there are no shorts to ground.

Then, go over the driver end of things. Make sure the dimming signal is wired correctly. Check it with a VM to make sure you are getting 10v at full on. Check other driver-related wiring.

If you are 100% totally sure that there are no problems in the array or driver wiring in terms of dead LEDs, wiring, or soldering problems, then try swapping the driver from the functioning string to this non-functioning string.

thanks again dwzm.
I swapped out the driver and it looks like I'm having issue with driver.

I swapped out the driver and it looks like I'm having issue with that driver.
