\centerline {\bf 1.3\_V2.1 TURN ON DPA A \& B AND DEA A (realtime version) } 
\vspace{0.25in}

\normalsize
\noindent{\it Last Revised: June 25,1999}\\
\noindent{\bf Filename: dpaab\_deaa\_on} \\


\noindent {\bf BRIEF FUNCTIONAL DESCRIPTION:} \\
\normalsize
This is an ``atomic'' procedure which simply powers up the DPA sides A
and B and DEA side A.  It should be safe to execute under any
condition except a spacecraft power or thermal emergency.
The DEA side A is powered up first so that the default configurations
can be loaded into the DEA when DPA side A and BEP A are powered up.

\vspace{0.25in}
\noindent The sequence of actions will be: 
\be
\item enable and turn on DEA power supply side A
\vspace{-0.10in}
\item enable and turn on DPA power supply side A
\vspace{-0.10in}
\item check that BEP A boots properly
\vspace{-0.10in}
\item check the HW LEDs
\vspace{-0.10in}
\item check the SW LEDs
\vspace{-0.10in}
\item enable and turn on DPA power supply side B
\vspace{-0.10in}
\ee


\vspace{0.15in}
\normalsize
\noindent {\bf ASSUMED INSTRUMENT STATE:} \\
\normalsize
Assumes that the PSMC has power from the spacecraft. \\


%\vspace{0.25in}
\normalsize
\noindent {\bf SPECIAL INITIAL CONDITIONS:} \\
\normalsize
%The environment must be clean enough to allow opening of the valve. \\
%Assumes that \axaf\/ ISIM RCTU is powered on and in telemetry format 6. \\

\normalsize

{\bf V1.2}
\begin{itemize}
\item changed filenames from ``turnon\_dpaab\_deaa'' to
``dpaab\_deaa\_on''
\item changed the procedure to turn on the DEA~A first, then turn on
the DPAs
\end{itemize}

{\bf V1.3}
\begin{itemize}
\item added DEA current and voltage tlm verifiers in step 1
\end{itemize}

{\bf V1.4}
\begin{itemize}
\item deleted DEA input current as a verifier in step 1
\item changed the expected values of the DEA voltages in step 1.2
\item changed expected values of DPA A input voltage, DPA A input current
and DPA A 5~V supply in step 2.2 
\item expanded SW tlm verifiers in step 2.3
\item added HW LED verifiers in step 2.4
\item added SW LED verifiers in step 2.5
\item changed expected values of DPA input voltage, DPA input current
and DPA 5~V supply in step 2.2 
\end{itemize}

{\bf V1.5}
\begin{itemize}
\item  changed expected values of the DPA A input voltage and current in
step 2.2 to 28.0--34.0~V and 0.35--0.43~A and DPA B input voltage and
current in step 3.2 to 28.0--34.0~V and 0.26--0.32~A
\end{itemize}

{\bf V2.0}
\begin{itemize}
\item ACIS Team signed-off version
\item fixed typo in ``Description'' column in step 2.4
\end{itemize}

{\bf V2.1}
\begin{itemize}
\item changed expected value of ``1STAT7ST'' to ``0'' in step 2.4
\end{itemize}
