Component

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.
