org.lsst.ccs.subsystems.fcs.LoaderModule

All Implemented Interfaces:

Serializable, Observer, org.lsst.ccs.framework.Configurable

public class LoaderModule
extends org.lsst.ccs.framework.Module

This is the model for the loader in the Filter Exchange System. The loader is used to load a filter into the camera or to unload a filter from the camera.

LoaderModule

public LoaderModule(String moduleName,
            int aTickMillis,
            org.lsst.ccs.subsystems.fcs.CarrierModule carrier,
            LoaderClampModule clamp)

Method Detail

isEmpty

public boolean isEmpty()

getClamp

public LoaderClampModule getClamp()

initModule

public void initModule()

Overrides:

initModule in class org.lsst.ccs.framework.Module

initializeHardware

public void initializeHardware()
                        throws HardwareException,
                               org.lsst.ccs.bus.ErrorInCommandExecutionException,
                               org.lsst.ccs.bus.BadCommandException

Throws:

HardwareException

org.lsst.ccs.bus.ErrorInCommandExecutionException

org.lsst.ccs.bus.BadCommandException

updateStateWithSensors

public void updateStateWithSensors()
                            throws HardwareException,
                                   org.lsst.ccs.bus.ErrorInCommandExecutionException

This updates the clamps state of the loader : clampsLockStatus

Throws:

HardwareException

org.lsst.ccs.bus.ErrorInCommandExecutionException

lockHooks

public void lockHooks()
               throws org.lsst.ccs.bus.BadCommandException,
                      org.lsst.ccs.bus.ErrorInCommandExecutionException,
                      HardwareException

This method closes the clamps. When this action is completed the filter is clamped softly on the loader and can't fall.

Throws:

org.lsst.ccs.bus.BadCommandException

org.lsst.ccs.bus.ErrorInCommandExecutionException

HardwareException

clampHooks

public void clampHooks()
                throws org.lsst.ccs.bus.BadCommandException,
                       org.lsst.ccs.bus.ErrorInCommandExecutionException,
                       HardwareException

This method closes the clamps strongly. When this action is completed, the filter is clamped softly on the loader and is tight fermely on the carrier.

Throws:

org.lsst.ccs.bus.BadCommandException

org.lsst.ccs.bus.ErrorInCommandExecutionException

HardwareException

unlockHooks

public void unlockHooks()
                 throws org.lsst.ccs.bus.BadCommandException,
                        org.lsst.ccs.bus.ErrorInCommandExecutionException,
                        HardwareException

This methods open the clamps.

Throws:

org.lsst.ccs.bus.BadCommandException

org.lsst.ccs.bus.ErrorInCommandExecutionException

HardwareException
