sensor dimmer not shutting off.

Hi All,

I have an sr48+ rack with d20 dimmers controlled by a CEM+.

Tuesday 1/23 during a dimmer check, dimmer 124 powered on and has since not powered off. today is Thursday 1/25.

  1. from the console i have checked that dimmer/channels are not parked. release all = light stays on
  2. dmx has been disconnected. console ( Expression 3) has been powered down.= light stays on
  3. turned off all panic stations.= lights on
  4. checked set and release levels and they are uniform down the rack.
  5. multiple dimmers in slot result in light on.
  6. original dimmer in different slot shows normal function.

the only way i can turn off the dimmer is by setting  it to off, or to 0. or tripping the breaker.

when i trip the breaker the signal light stays on but the circuit powers down.

I am at a loss as to what to do next.

any ideas?
