Problem with ts3000

Hello. Hoping to solve an issue with Mars hydro ts3000. It has two mean well elg 240 48a driver's both hooked to one potentiometer. When the light is turned up past 75% the light turns off. I can turn it down and it comes back on. Right as the dial hits 75 there is a popping sound from one of the driver's as it shuts off.

Both driver's have built in dimming as well. They were set to about 90% from the manufacturer. I turned them all the way up.

Is the potentiometer the wrong one and that's why they were internally turned down?

Everything seems to be wired right.

Any insight would be appreciated.

Got a warrantee? My xlg's don't do that.

Which xlg fo you have? M, L, H or 24V?
They dont all work the same but on the H version, coupled with boards around the higher range of voltage will defo do this. They are able to give 240w output on a range of voltage of 27-57V, so the max output in current would only be reachable on lower voltages (watts = current x voltage) However if it works on one and not the other there might be a problem.

Its normal. These constant power drivers work like that. 75% is max at the forward voltage of the mars boards. If they had lower voltage youd be able to turn current up further, but you would still be at 240w output per driver.
Would that be why they had the internal pots turned down a bit? I turned them up.

I got to thinking last night that was probably the reason, what you said. I was going to take a meter and measure as I turned it up.

It might be. I had xlg150-m (which works similarly) and had a hell of a time to work out how the external and internal dimmer worked together. Afaik the datasheet says the internal pot will set a limit for the external but im not sure it means your external will use this "new max" as the 100% external dim or if it just overrides the external when it gets to max internal dim. I wasnt sure in the end. My approach was just turn the internal up slowly and once it flickers and go out, just back up a little bit and leave it there.

I was searching on this last night and read of instances where the external would override the internal.

I think I'll just take a multimeter to it and adjust accordingly.

I don't know if this means anything. The external pot has a switch to turn it off and run on internal only. When I turn the external pot switch off and turn the light on, the light blinks on and off.

I also read that to turn the switch off and adjust internal with a meter. Once set then use external.

The XLG drivers are different to the ELG and HLG drivers in that if you try to exceed the rated output with the onboard current dial, the driver will go into limp mode and start flashing. You need to back off the current dial. That's why it is set at the factory. The external dimmer will not override the onboard current dial – whatever you set it at onboad the driver is the maximum power you will get from the external dimmer.
