This Howto outlines how to operate the Target ladder. 

\end{abstract}
 
\section {Motor and Controller}

The motors are attached at the side of an xyz-stage of  
the target ladder. Two limit switches for negative and 
positive positions, and home switch are placed on the sides.     
The control box is located at a rack in front of SOS power supplies 
in Hall C as well as the  control boxes for the slit boxes. 
These are operated from hcpc10401 (pc104 board PC) remotely. 
Current positions and status are read out and stored in EPICS and data. 

\section {Operation}

Type {\bf ./sst-control.tcl} from `hcpc10401' and see the window of 
{\bf Sieve slits / Target control for E01-011}. You can operate 
sieve slits and target ladder from this window. 

\begin {verbatim}
> 'STOP!'       stop running program. 
> 'Go home'     move to HOME switch +0.0.
> 'tgt1'-'tgt6' move to Target#. 
> 'Empty'       move to ``Empty'' position.
> 'Out'         move out from beamline by +10 for Target.
> 'In'          move into beamlime by -10 for Target.
> 'Reset'    reset contoller

\end{verbatim}

To move,  
\begin{enumerate}
\item Check the status message `Home successful'.  
\item Push the bottom of `tgt1' $\sim$ `tgt6' to move the ladder to the 
target 1 $\sim$ 6 position. 
\item Confirm `Position' is a right position. 
\item Confirm messages of `Move successful' and `Stopping...'.
\item Start run.
\end{enumerate}

\begin{itemize} 
\item Push the bottom of `STOP!' to stop running program. 
\item For trouble shooting and detail description about switches, read 
`Slit box Howto'. 
\end{itemize} 

\section {Positions list}

These are values of positions from controllers.
