FANUC Display A02B-0303-C084
A02B-0303-C084 is a FANUC display unit that the seller names in its own catalogue — one of two named display numbers in the A02B range. This page records it and the display-ordering checks that go with it.
What A02B-0303-C084 is
A02B-0303-C084 is a display unit from FANUC's operator-interface range, named directly in the seller's display family alongside the forms that family publishes — CRT, LCD, LCD/MDI and Panel i. Its A02B number puts it in the same prefix range as the control units, which is why the A02B page lists controls and displays in one table with their roles marked: this number's role is display.
A display is ordered against the control whose panel it serves. The number identifies the unit; the control series named beside it in an inquiry confirms the marriage, and the desk checks the two together before answering.
Where A02B-0303-C084 works
The unit is the operator's window into the control: program, position, alarms and parameters all pass across its screen. Its failure modes divide into the screen's own — darkness, distortion, dead areas, fading — and the fed signal's, which belongs to the graphics board inside the control and is shelved under PCBs. A buyer unsure which side has failed can describe the screen's behaviour precisely and let the desk sort the addresses.
The sibling named display, the A02B-0120-C051 CRT MDI unit, is the other anchor of this family; between them they mark the two ends of the display shelf, the named unit and the combined MDI form.
Condition options for A02B-0303-C084
The catalogue names this display without a fixed condition word, so the shelf unit's condition is stated on inquiry. Displays are the family where condition language needs the most care: a used display's real state is its picture — brightness, uniformity, legibility — and the condition answer for this number addresses the picture, not just the word.
The framework on the used FANUC parts page governs: stated condition, a test before dispatch in which the unit is lit and run, the seller's warranty behind it, and a test video on request — for a display, the video is the condition evidence, and asking for it is routine.
Testing A02B-0303-C084 before dispatch
A display is tested lit: powered on the test bench, showing a picture, run long enough for warm-up faults to declare themselves. A display that lights cold and fades warm has failed the only test that matters for its kind, and the bench process is built to give it the time to fail there rather than at the buyer's panel.
If the buyer's own display is the suspect and the graphics board has not been cleared, the repair desk can assess the control-side board in parallel — the two-suspect method that keeps a display purchase from becoming a diagnostic step.
Ordering A02B-0303-C084
Quote the number in full — A02B-0303-C084 — read from the rear label of the fitted display, and name the control series whose panel it joins. State the form the machine carries if it differs from what the number suggests, and the condition you will accept. If the existing screen still shows anything at all, describe what it shows: that description is diagnostic gold and costs one sentence.
