Recovery of Lost Fibers

The button sensing of the gripper will halt the positioning routine if there is a dropped fiber or one that it couldn't pick up. In most cases, the errant fiber can easily be recovered through use of the gripper TV camera.

The following steps should be used for simple fiber recovery.

If the lost fiber can not easily be found with the viewer, have trained personnel (the Observing Tech) go to the telescope and inspect the hardware. If they had to reset the lost fiber by hand, they will have placed it into its stow position. The software will have to be informed of this action with the following command.

xstowed < fiber#>

That fiber should then be parked with
park < fiber#>

before normal operation can resume.
