Thank you for contacting us about your system.
It sounds like you have a DPS2 preset slide controller. But can not be certain. Please see if there is a sticker on the dimming cabinet in the electrical room, if there is please see if there is a job name and or job number listed. We may be able to locate the original shop drawings of the cabinet and controls. If not, pictures are always worth a 1000 words. Please post here or email the pictures to firstname.lastname@example.org
The Macro units can be evaluated and repaired here at our factory in Oregon. Please contact us for RMA # if you would like to proceed.
We would recommend that you contact one of our local reps in your area for any product conciderations, ect..
