public class AutochangerThreeOnlineClamps
extends MobileItemModule
implements ControlledBySensors

The Three Online clamps which holds a filter when it is at ONLINE position can ve viewed as a single object. It's the goal of this class to represent this object. Opening or closing the 3 clamps at ONLINE is not the same action as opening or closing online clamps one by one.

@Command(type=QUERY,
         level=1,
         description="Returns true if the 3 clamps are OPENED.")
public boolean isOpened()

Returns true if LockStatus=OPENED

Returns:

isInError

@Command(type=QUERY,
         level=1,
         description="Returns true if one of the clamp is in error.")
public boolean isInError()

Returns true if LockStatus=ERROR

Specified by:

isInError in interface ControlledBySensors

Returns:

public void initModule()

Overrides:

initModule in class MobileItemModule

isInitialized

@Command(type=QUERY,
         level=0,
         description="Return true if the 3 onlineClamps hardware is ready : controllers ready, controllers parameters checked and controllers configured.")
public boolean isInitialized()

Return true if the 3 onlineClamps hardware is initialized.

Returns:

@Command(type=ACTION,
         level=0,
         description="Closes and locks the online clamps.")
public void closeAndLockClamps()

Closes and locks the online clamps. This command first release brakes, sends currentToClose to the 3 clamps controllers and then increases progressively current until currentToClamp is reached for every clamps controllers. state before this action : OPENED or CLOSED (if CLOSED, nothing has to be done) state after this action : LOCKED

Throws:

FcsHardwareException
