Symptom
Scanner stops with Spit Ratio and/or Rotor errors. Long Description for Feedback Only. Scanner stops with Spit Ratio and/or Rotor errors.
Error message
Error: 260118168 (40-0105) Rotation Phases unbalanced See LD for error explanation Code 40 Error code: 40-0105H Message/explanation: Rotation Phases unbalanced The amplitude difference of the current between main and auxiliary is too large. Potential cause: 1. Tube stator winding problem 2. Incorrect wiring (one wire open) 3. Phase shift capacitors inverted or wrong value or not connected 4. Rotation board Recommended action/ Troubleshooting guide: Disconnect rotation-to-tube-stator cable and check stator windings impedance. If not OK, replace tube. Check wiring from rotation board to tube. Check that phase shift capacitors are correctly connected Check that phase shift capacitors are not in short-circuit Run Rotation diagnostic (See diagnostic section). If test fails, replace Rotation board Tue May 9 09:26:56 2006 Error: 186218 Host: IRIS Process: tgp_out File: tgp_in_input.c Line: 335 XG Error phase is 3 code is 40. detail error code : 40 - 0105H Rotation error : Rotation Phases unbalanced Error: 260118214 (60-0317) Spit Ratio error See Long Description for complete error.

See Long Description for more info and Picture D3186T PERFORMIX ULTRA TUBE UNIT Used on LS2.X, 3.X, 4.X, 5.X HP60, Hispeed QXi, DLS with H2 Gantry and DST with H2 Gantry. Part #: D3186T Part Type: GP TUBES Part Weight: 184.31 LBR Repairable: No Returnable: Yes Hazardous Material: N Description: PERFORMIX ULTRA TUBE UNIT FRU: Yes Status: Orderable Comments: ** FE ASSIST ** The Shipping weight of this Tube is 336 lbs = 152 kilogram. For LightSpeed 2X/3X/4X and HP60. For CTi order D3132T and Lightspeed 1X order D3176T (212001261 5/3/07) *** SECOND OPINION NOTES *** Perform Rotor Control Diagnostics--If tube rotor fails to reach RUN mode in three ACCEL steps look for: High Drive output currents Low Drive output voltages and Low Drive output frequencies. This indicates a load problem with tube. With rotor running turn off Gantry 120V power at PDU. Listen for excessive noise and short deceleration time. A good rotor will coast for several minutes without power. Rotor issues (errors 183316, 183318, 183319, 260118111, 260118177) caused by tubes tend to be more prevalent on .5 second scans. If tube is installed on Jedi system, the Anode cable tends to break down (hard errors). Intermittent HV Spits -- Run KV Loop, 140KV, 30 sec, Anode, Cathode and both. Listen to tanks with stethoscope or screw driver, any noise indicates bad tank. Any spits? Remove HV cables from tanks fill with 2inch of oil. Spits = No, could be tube or cables. Spits = Yes, bad tank. D3186T PERFORMIX ULTRA TUBE UNIT Used on LS2.X, 3.X, 4.X, 5.X HP60, Hispeed QXi, DLS with H2 Gantry and DST with H2 Gantry.
