C.BRICKLER 4/6/98 ****NOTES FOR CD TEAM************************* ALL PARTS ON HAND HAVE BEEN REPAIRED USING THE NEW PROCEDURES. DO NOT USE THE 2205390H2 PART NUMBER ANYMORE.MS26561 DSM 11/16/01 ** FE ASSIST ** The HV adapter/Spacer part number 2171866 Kit that is included with the HV tanks But it is only used on older Highspeed Gantry due to the smaller bolt size. Refer to MI&CT ESERVICE NOTE SN07091114a for additional details. (212001261 21-Jan-2009) *** 2ND OPINION NOTES *** Check Oil in wells. Prior to ordering tube INSTALL NEW TUBE should be run to regenerate calseed values and set up the gencal table. The tube should be isolated and the KV loop test run to verify with 90% degree of certainty the tube is or is not at fault 4/7/98 2205390 1.0 0.5 SEC/REV CATHODE HV SUPPLY D3176T PERFORMIX LIGHTSPEED TUBE UNIT for QXI 1.x D3176T PERFORMIX LIGHTSPEED TUBE UNIT for QXI 1.x Part #: D3176T Part Type: GP TUBES Part Weight: 0.00 LBR Repairable: No Returnable: Yes Hazardous Material: N Description: PERFORMIX LIGHTSPEED TUBE UNIT FRU: Yes Status: Orderable Comments: If you have a CTI Need to order an D3132T. For LightSpeed 1X you must order D3176T. For LightSpeed 2X/3X/4X and HP60 please order D3186T *** 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. Special Exception: No RMA will be auto-created for this part. Please ship back to warehouse via the normal process.
