TWP/TSI/C1 - obstruction in lens
DataStreams:twptsiC1.00, twptsimovieC1.a1, twptsicldmaskC1.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.

TWP/TSI/C1 - Shadowband continuosly rotating
DataStreams:twptsiC1.00, twptsimovieC1.a1, twptsicldmaskC1.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.

TWP/TSI/C1 - solar shadowband inoperative
DataStreams:twptsimovieC1.a1, twptsicldmaskC1.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.
