DataStreams: | twptsiC2.00, twptsicldmaskC2.a1, twptsimovieC2.a1, twptsiskycoverC2.b1, twptsiskyimageC2.a1 |
Description: | The operation of the camera was itermittant. It produced very poor "hazy" images, blank white images, or no images when the camera failed to respond. Several attempts were made to correct the problem, involving checking the power and ethernet connections and wire and cleaning the lens and filter. The camera was replaced by a spare. |

DataStreams: | twptsicldmaskC2.a1, twptsimovieC2.a1, twptsiskycoverC2.b1, twptsiskyimageC2.a1 |
Description: | Condensation in the camera lens and/or filter caused the sky images to be "hazy". The desiccant in the main enclosure was changed and the neutral density filter was cleaned. |

DataStreams: | twptsicldmaskC2.a1, twptsimovieC2.a1, twptsiskycoverC2.b1, twptsiskyimageC2.a1 |
Description: | The mirror began to continuously spin. Diagnostics were performed on the encoder, control board, and Ethernet adaptor. The instrument was removed on 1/2/2008 and shipped to Darwin for repair. The encoder and control board were replaced and the instrument was reinstalled. |

DataStreams: | twptsicldmaskC2.a1, twptsimovieC2.a1, twptsiskycoverC2.b1, twptsiskyimageC2.a1 |
Description: | The mirror was continuously rotating and communication with the control board failed. As a result, the sun was not being blocked by the shadowband. The ethernet-to-serial adaptor was replaced. |

DataStreams: | twptsicldmaskC2.a1, twptsimovieC2.a1, twptsiskycoverC2.b1, twptsiskyimageC2.a1 |
Description: | The indicated dome temperature and heat sink temperature were unreasonably high. The control board and serial adaptor were replaced and the instrument was shipped to Darwin for repair where the following was performed: - changed out 12V battery, - changed out faulty TT8 processor s/n 939476 with spare s/n 939476, - installed new model Lantronix EDS1100 serial to ethernet adapter, - modified board to adapter data connection to suit new adapter, - changed out two faulty temperature sensors (heatsink and dome), - changed out corroded heatsink fan and faulty wiring, - replaced damaged heater wiring, - removed corrosion and re-painted camera bracket, - waxed and polished dome mirror and whole instrument body. |
