org.lsst.ccs.subsystems.fcs.Autochanger

All Implemented Interfaces:

org.lsst.ccs.framework.HasLifecycle, AlertRaiser, FilterHolder

Direct Known Subclasses:

SimuAutochanger

public class Autochanger
extends Object
implements FilterHolder, AlertRaiser, org.lsst.ccs.framework.HasLifecycle

This class is used with the final hardware and prototype in which we have online clamps to hold the filter at online position. It's not used for Single Filter Test. CAMERA PROTECTION SYSTEM Signal comming from carousel : CS : Carousel stopped on socket CF0: No filter in carousel socket CF1: Filer in carousel socket CFC: Filter clamped on carousel socket Signal coming from loader : LPS: Loader at Storage position (loader is connected) LRH: Loader at Handoff position, closed but not clamped Local Protection Module Signals emitted by AC: enableRailLin1 enable master linear rail (X+) enableRailLin2 enable slave linear rails (X-) enableClamps enableLatches Sensors in AC1 and AC2 and not in PROTO : loaderPresenceSensors * lockOutSensors
