\subsection{IMD Latching}
\begin{itemize}    	
	\item The \texttt{IMD\_OK} signal is pulled high approximately 1.5 seconds after startup for the \href{https://www.bender.de/fileadmin/content/Products/d/e/IR155-32xx-V004_D00115_D_XXEN.pdf}{IR155-3204 IMD}.
	\item Therefore the Power-on Reset (PoR) lasts approximately 2 seconds.

\end{itemize} 
\subsection{AMS Latching}
\begin{itemize}	
	\item The \texttt{AMS\_OK} signal is pulled low until the following conditions are met:
	\begin{itemize}
		\item The AMS Master communicates with all six AMS Slaves, each providing valid voltage and temperature measurements.
		\item The AMS Master mommunicates with the shunt sensor (IVT-S-300-U3-I-CAN2-12/24)
	\end{itemize}
\end{itemize}


\section{SCS signal implementation}
\begin{center}
	\begin{circuitikz}[]
		% CAN
		\draw[purple] (0,2) -- ++(1,0);
		\draw (1,2) node[right]{$0.13mm^2$ unshielded - RS PRO 8724476, 2A};

		% IMD
		\node[draw, minimum width=1.5cm, minimum height=1cm] (AMS) at (0,0) {AMS Master};
		
		% AMS Master
		\node[draw, minimum width=1.5cm, minimum height=1cm] (DB) at (8,0) {{Dashboard}};
		\node[draw, dashed, fit=(AMS), inner sep=0.5cm, label=above:Accumulator] {};
		% Arrows
		\draw[->, thick] (AMS.east) -- (DB.west) node[midway, above] {IMD\_OK} node[midway, below] {AMS\_OK};
	\end{circuitikz}
\end{center}
\paragraph{}
Both signals are transmitted every 50 ms over the CAN bus. If the Dashboard does not receive a CAN message from the AMS Master within 150 ms, 
it will trigger a fault condition. In response to this fault, the following LEDs will be activated: 
the \texttt{AMS Error} LED will be turned on, the \texttt{IMD Error} LED will be turned on, and the \texttt{TS Off} LED will remain off.
