Operation Name Clamp Install Procedure
Operation Time \~1h
Operation Description Each filter are held on the carousel using two clamps (1 X- & 1 X+) , on each side of the filter. When there is no filter engaged in a given carousel slot, the associated clamp(s) can be (un)-installed if needed.
Triggered by Maintenance The regular maintenance frequency of the clamps is not precisely known, we recommend to have at least one of each clamp kind replaced each \~ two years for full inspection. Tracking the usage duration of each clamp is mandatory.
Triggered by Monitoring Analysis Analyzing the filter exchange operation should allow to identify a decrease in performances of a given clamp. The identification of the issue / the trigger for a maintenance is still under investigation.
Triggered by Incident recovery Clamping-Unclamping failure may trig the dismounting of a clamp, to allow for a clamp inspection or replacement.

The best access to remove a clamp is to use the windows on top of camera body when the camera is in maintenance postion in Chile. They are near the auto-changer slot. In respect of this photo to remove a X- clamp the two access windows on the left ( to be confirmed ??? ) should be opened and for a X+ clamp the two access windows on the right ( to be confirmed ??).
