Did the LCD screen show an error message ?, Arch Failure ?. And what do you mean by "It's not 100 percent" ?.Our unison system crashed and evidently the programming was erased. It is possible a power spike of somekind ( it's completly unregulated power coming in to the system) caused the fatal error? I know it's not a 100 precent, but has anyone ever heard of this kind of problem? Many thanks Chris
Yes, a good point pertaining to an ER4 mounted in a Unison dimmer enclosure. My ER4 is in a standard electronic rack.The only drawback with leaving the disk like that is that, on occasion, it has been known to catch the back side of the door and prevent the entire door from opening.
