Luminometer PMT Cable with Ferrite EMI Filter Removal and Replacement

Parts and Materials Required

Time Required

  • 10 minutes (Removal and Replacement of the new PMTClosedPhotomultiplier tube cable)
  • 10 minutes (Luminometer Darkcount Procedure)
  • 40 minutes (OQ Procedures)

Preparation

  1. Put on proper PPE.
  2. Open the right side panel door of the Panther System.
  3. Open the Service Drawer.
  4. ClosedLocate the Luminometer module.

Removal Procedure

  1. ClosedLocate the PMT Cable and connections.
  2. ClosedCarefully release the two retaining latches that secure the PMT cable to the main Luminometer PCB by pushing the latches in an outward direction.
  3. ClosedGently disconnect the PMT cable from the main Luminometer PCB.
  4. ClosedDisconnect the PMT cable from the PMT PCB using the same method described in steps 2 and 3.

Replacement Procedure

  1. ClosedObtain a new PMT cable with the ferrite EMI filter. The end of the cable that attaches to the PMT PCB is the connector with the key feature oriented away from the ribbon cable.
  2. ClosedSecurely connect the new PMT cable to the main Luminometer PCB by pushing the PMT connector into the mating PCB connector and squeezing the two retaining latches inward. Make sure the latches are fully snapped into place—the connector must be fully seated.
  3. ClosedSupport the back of the PMT PCB as shown below and press the PMT cable connector into the mating PMT PCB connector.
  4. ClosedSqueeze the two retaining latches inward. Make sure the latches are fully snapped into place—the connector must be fully seated.
  5. ClosedVerify all connectors are secure and the cable is not interfering with any other components.
  6. Securely close the Service Drawer.
  7. Close the right side panel door of the Panther System.

Alignment/Calibration

  • None

Verification

  1. Perform one cycle of the System Level OQ Procedure.
  2. Perform the Luminometer Darkcount Procedure.
  3. Perform a Panther Luminometer SysCheck Reagent Verification Procedure.
