ROBE T2 Profile troubleshooting

Common T2 Profile errors & problems

What techs run into most, and what's usually behind it. The step-by-step fix for your exact unit is in Ask Roadie.

• Beam drifts / head shifts position on a moving or vibrating truss

  Likely cause: EMS actively counters truss movement and vibration to hold pan/tilt; calibration aligns the stabilizer, and comms errors indicate a wiring/PCB fault.

• Camera flicker on HD/UHD shoots, or dimming looks stepped at low levels

  Likely cause: Cpulse manages the LED PWM to eliminate rolling flicker on camera; L3/16-bit dimming gives imperceptible fades to black instead of visible steps.

• Colour looks wrong / patchy, or a "…Short Error" (e.g. Blue 3 Short Error, Red 2 Short Error) appears

  Likely cause: The T2 monitors each colour string; a hard short/open is a hardware fault, but running RCC (Robe Colour Calibration) re-matches whites/colours so T1 and T2 fixtures stay consistent.

• Display shows "Recharge The Battery" or "Battery Faulty. Replace it." / display loses settings when unpowered

  Likely cause: The battery keeps the real-time clock and operation memory alive with power off; recharging or replacing it restores retention.

• Fixture does not respond to console / no DMX, or Ethernet (Art-Net/sACN/MANet) not coming through

  Likely cause: A profile/mode or addressing mismatch is the most common "no response" cause; matching mode+address and setting the right protocol/IP restores control.

• Gobo/prism/iris/frost/zoom/focus mechanism "Error 1" or "Error 4"

  Likely cause: These positional effects home against an end-stop sensor; Error 1 (no stop found) vs Error 4 (obstruction hit) tells the tech whether to look for a blockage or a failed sensor/motor.

• Head will not move / grinds / Pan or Tilt Error after power-up; fixture just powered on from a case

  Likely cause: The head cannot reach its home/magnetic-index position while a transport lock is engaged, so the feedback system reports a Pan/Tilt error.

• How to update firmware / software on the T2 Profile

  Likely cause: ROBE Uploader is the manufacturer tool and handles the RDM/Ethernet path; RUNIT DSU covers non-RDM one-to-one flashing — matching the fixture keeps DMX chart and features current.

• Internal Error 1 or Internal Error 2 on the display; a module shows N/A under Information > Software versions

  Likely cause: The T2 boards talk on an internal bus; the software-versions list is the fast way to spot which PCB has dropped, turning a vague error into a specific board to check.

  Step-by-step fixGet the fix →

• Light output shuts off; fixture running hot; suspected overheating

  Likely cause: The T2 closes the shutter/light output to protect the LED engine when a cooling fan fails or ambient exceeds spec; restoring airflow and clearing the fault re-enables output.

  Step-by-step fixGet the fix →

• Pan Error 1/2/3 or Tilt Error 1/2/3 on the display

  Likely cause: The T2 homes pan/tilt against magnetic index sensors on reset; a one-off miss clears with a clean reset, a persistent miss points to a failed sensor/magnet or motor.
