\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 communicates with the shunt sensor (\href{https://www.isabellenhuetteusa.com/wp-content/uploads/2022/07/Datasheet-IVT-S-V1.03.pdf}{IVT-S-300-U3-I-CAN2-12/24})

|
|
\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.
