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.
