Subject: | TWP/TSI/C1 - obstruction in lens |
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. |

Subject: | TWP/TSI/C1 - high control board temperature |
DataStreams: | twptsiskycoverC1.b1 |
Description: | The TT8 control board temperature was high, ~50C, so that the cooling fan was constantly on. It appears that the heat sinks were not transferred from the original board to the new one when it was replaced. The problem was corrected when heat sinks were installed. |

Subject: | TWP/TSI/C3 - mirror continously rotating |
DataStreams: | twptsicldmaskC3.a1, twptsiskycoverC3.b1 |
Description: | The mirror/shadowband was rotating continously because of a serial communication problem with the control board. The problem was corrected when the Ethernet-to-serial adaptor was replaced. |

Subject: | TWP/TSI/C1 - shadowband misalignment |
DataStreams: | twptsicldmaskC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1 |
Description: | The TSI mirror controller was configured with a north latitude instead of south causing the shadowband to not mask the sun beginning at the vernal equinox. The problem was corrected by changing the sign of the latitude in the configuration file. |
