DataStreams: | twptsicldmaskC2.a1, twptsimovieC2.a1, twptsiskycoverC2.b1, twptsiskyimageC2.a1 |
Description: | The TSI camera was producing either poor or no images during this time. The problem was corrected by disconnecting and reconnecting the cable terminations to the camera both inside the main enclosure and in the camera housing. |

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: | twptsiC1.00, twptsicldmaskC1.a1, twptsimovieC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1 |
Description: | The TSI at Manus has been able to remain dry and produces an image but the percentage of cloud cover is determined to be 100% even on cloud free days. Moisture in the camera lens and neutral density filter was corrupting the sky images. The lens and filter were cleaned, the moisure seals checked, the camera housing sealed, and desiccant added to both the camera housing and main electronics enclosure. On 3/23/2006, the lens was replaced and the sky images were significantly improved. |

DataStreams: | twptsiskycoverC3.b1, twptsicldmaskC3.a1, twptsimovieC3.a1, twptsiskyimageC3.a1 |
Description: | The mirror control board failed and was replaced with a spare. Several images were collected in the iterim that should be ignored. These images include periods when the sun was not masked by the shadowband, the camera lens was covered by red tape to protect the CCD from direct exposure to the sun and, the instrument was inside the shop for repair and testing. |

DataStreams: | twptsiC1.00, twptsicldmaskC1.a1, twptsimovieC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1 |
Description: | The mirror was continuously spinning during different periods of the day, usually in the afternoon, causing the shadowband to not properly block the sun. This problem was corrected by removing the real-time-clock integrated circuit DSI306, or EEPROM U10, from the control board and reloading the position and time parameters. |

DataStreams: | twptsicldmaskC1.a1, twptsimovieC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1 |
Description: | The mirror/shadowband was not turning and there was no communication with the control board. The shadowband was stuck in the position of 0 degrees from 8/29 to 9/20/2006. On 10/12/2006, the mirror was replaced, the real-time clock chip was removed and heat sinks were added to the control board, and the Ethernet hub and serial adaptor were replaced. On 1/8/2007, the slip clutch assembly, timing pulley, and timing belt were replaced (which were damaged when the mirror was replaced). These actions did not correct the problem. The instrument was swapped with the unit from Darwin so that the control board could be repaired and tested in Darwin. Several images were collected in the iterim that should be ignored. These images include periods when the sun was not masked by the shadowband or the camera lens was covered by tape to protect the CCD from direct exposure to the sun. There are also extended periods of missing data when the instrument was shutdown, waiting for parts. |

Description: | When the TSI from Darwin was installed (so the instrument from Manus could be returned to Darwin for repair) moisture in the camera lens and filter caused the sky image to be very "hazy". The U10 chip was removed from the control board, desiccant was installed inside the enclosure, additional small desiccant bags were installed inside the camera housing, the camera housing was sealed with silicon to prevent moisture ingress, and the camera lens filter was cleaned and the focus adjusted. |

DataStreams: | twptsimovieC3.a1 |
Description: | The computer began "locking-up" every day at 11:15 UTC when the program that makes the daily movies is automatically run. Site Operations had to reboot the computer everyday upon arrival at about 21:30. On 7/28, basic disk maintenance was performed that included error-checking, file purging, and defragmentation. On 7/29, file management was performed, the programs to create the missing daily movies was manually run, and the times of scheduled tasks were optimized. |

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. |
