0-10V Dimming

[Sparky704]

The owners of an ice hockey arena want some 277V MH high bays retrofitted with 296W LEDs. They are now switched through a Leviton relay panel controlled by a 3 button station with setting of all lights on, half ice, or seating lights. They want to install 4 dimmers to dim center ice, one end of ice, other end of ice and seating lights. They are split up into roughly 8 circuits right now 2 rows per circuit, original installation was reloc cables not conduit and sharing neutrals from relay panel. My question is, is it possible to dim the lights in the new manner the owner would like without rewiring the line voltage side of the fixtures and just controlling them off a 0-10V dimmer not using any line voltage because of the way the fixtures are currently circuited?

Yes, assuming the drivers have 0 to 10 volt dimming leads you can do what you want.

do the lights have 0-10 volt leads on the drivers? yes, then you are good.

if you are hard wiring the 0-10, that paints you into a corner about zones,
lighting schemes, etc. with something they almost positively will want to
fiddle with, going with an addressable system like lutron eco with a grafic
eye will let you do anything you want with any light, in any number of
configurations.

nLight is even more flexible. you have a module that can drive a 0-10 light,
or a group of them. you have a gateway, and some bridges, and it all plugs
together with cat 5. you can put a single gang device anywhere you like,
and make it do about anything you want.

disclaimer: this stuff is not cheap. and yes, you just feed the lights hot
with whatever voltage or circuit you wish. the 0-10 controls what the light does.

Yes the fixtures have 0-10V dimming capabilities, I guess I've just always fed a dimmer with the hot circuit and ran the switch leg up to the light along with the dimming cable. Never installed a dimmer using just the dimming cable and not applying any line voltage to it.
