Operation Description | Lubrication of the main carousel gear. The lubricant is applied through a dedicated tool replacing temporarily one of the carousel break. |
Triggered by Maintenance | Regular lubrication of the main carousel gear is expected. The frequency of lubrication has still to be determined. It is expected that it will be at a lower frequency than the scheduled maintenance period of the camera ( \~ 2 years) . |
Triggered by Monitoring Analysis | Analyzing the power consumption during filter exchange and the fft of full carousel rotations, should allow to identify an increase in friction, the identification of the issue / which rotating part is involved in the performance degradation, is still under investigation. |
Triggered by Incident recovery | Unlikely |

60,10 | When unpowered the brakes are locked, preventing carousel rotation. Removing a single break from the carousel, leaving the two other in place , will still grant that the carousel , even unbalanced, will not move. | ||
60,20 | TBD A procedure to remove old grease has still to be defined. | ||

100,10 | There is 3 breaks on the carousel ( Bay X,Y,Z) . For the lubrication of the ring gear we recommend to remove the break from Bay X TBD : We should identify which bay is the best for this operation | ||
100,20 | The bay protection panel should be removed | ||
100,10 | |||
The 2 breaks & motor handles should be put in place on the brake frame, to have an easy way to handle a brake once it will be unscrewed from the back flange. | |||
