Common LEDBeam 350 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.
- Step-by-step fixGet the fix →
Display shows "Clea Air F" (clean air filter reminder)
Likely cause: The message fires when the "R Ti" remaining-time counter in the Air fil menu reaches 0.
- Step-by-step fixGet the fix →
Display shows "Pan Err" or "Tilt Err" after power-up/reset; head not in default position
Likely cause: The message appears when the head fails to reach its default pan or tilt position after reset — caused by a failed indexing sensor, a defective stepper, or a bad driving PCB.

Display shows a colour "Shrt" message (Red Shrt / Green Shrt / Blue Shrt / White Shrt)
Likely cause: "Shrt" = short circuit detected on the named colour channel of the LED PCB; the driver flags it to protect itself.
- Step-by-step fixGet the fix →
Display shows a colour "Unp" message (Red Unp / Green Unp / Blue Unp / White Unp)
Likely cause: "Unp" (unplugged/open) means the current path for that colour is broken — a disconnected harness or failed LED string on the PCB.

Fan noise too high, or fixture runs hot / overheating concern
Likely cause: cooling is a deliberate trade-off in the fan menu; most "loud" complaints are Quiet-vs-High settings, and most "hot" complaints are blocked vents or a dirty filter rather than a hardware fault.
- Step-by-step fixGet the fix →
Fixture will not respond to the console / wrong channels / display flashing address
Likely cause: No-response almost always traces to an address/personality mismatch or a dead data path.

How to update firmware / software on the LEDBeam 350
Likely cause: Robe distributes fixture software through the Uploader/Toolkit over USB or the RS232/DMX flash cable; pulling the current version keeps error-handling and feature fixes current and preserves warranty.

Setting up an EP (Ethernet) version on Art-Net or sACN / no output over network
Likely cause: Network output requires the correct protocol mode, unique IP addressing, and matching universes; the 8-fixture pass-through limit and EP-only RJ45 hardware are the two constraints techs most often miss.
- Step-by-step fixGet the fix →
Wireless DMX (CRMX) will not link, or fixture keeps old link
Likely cause: These heads have no internal radio — the dongle is mandatory.
