\vspace{0.25in}

\normalsize
\noindent{\it Last Revised: June 23,1999}\\
\noindent{\bf Filename: bakeout\_m50} \\

\noindent {\bf BRIEF FUNCTIONAL DESCRIPTION:} \\
\normalsize
This is an atomic procedure which raises the focal plane temperature
to -50~C. {\bf THE INSTRUMENT IS LEFT IN A STATE WITH THE FOCAL PLANE 
BAKEOUT ENABLED AND THE FOCAL PLANE TEMPERATURE ELEVATED TO -50~C.}

\vspace{0.25in}
\noindent The sequence of actions will be: 
\be
\item start a DEA HKP run if necessary
\vspace{-0.10in}
\item enable FP bakeout and start heating FP to -50 C
\vspace{-0.10in}
\item verify that the FP temp stabilizes at -50 C
\ee

\noindent {\bf ASSUMED INSTRUMENT STATE:} \\
\normalsize
Assumes the instrument is in the canonical thermal standby state (the
video boards and FEPs should be off !!!!).\\

\normalsize

{\bf V1.2}
\begin{itemize}
\item changed filenames from ``bakeout\_m50C'' to ``bakeout\_m50''
\end{itemize}

{\bf V1.3}
\begin{itemize}
\item removed commands to turn on the DA housing heater
\item removed commands to disable the focal plane bakeout
\item added the command to set the warm boot flag off in step 2.2
\item added ``dumpSysConfig'' command in step 2.6
\item created a new step to explicitly wait for temperature stabilization
\item added radiator and camera body temperatures to the list of
verifiers in step 3.1
\item added commandEcho values in steps 1.1, 1.2, 2.5 \& 2.6
\item added filename identification at top of procedure
\end{itemize}


{\bf V1.4}
\begin{itemize}
\item changed HW TLM verifier in step 2.1 to 1DE28AV0 from 1DEP3AVO,
and expected value to 27.0-35.0~V, and changed DEA A input current
to 0.60--0.78~A
\end{itemize}

{\bf V2.0}
\begin{itemize}
\item ACIS Team signed-off version
\item changed expected value of the cold radiator temperatures
(1CRAT,1CRBT) in step 3.1 to be -90~C
\end{itemize}
