The cooling plant of TRD is located right behind the O-side door after going down with elevator
and it looks like \autoref{fig:CoolingPlant}.



\subsection{Cooling Alarms}\label{sec:CoolingAlarms}

Critical faults on cooling plant causes putting cooling plant to Stand-by mode (water pump stops but vacuum pump keeps running).
Corresponding ``alarm'' messages are sent to experts via SMS.
In addition, it stops all Wiener power supplies via DSS interlock system.

Alarm happens for the cases below:

\begin{description}

  \item[High Pressure at Super-Module] 

    If any of the the pressure measured at inlet of super-modules reaches 940~mbar, cooling is put to Stand-by with alarm.
    There is also a warning limit (currently at 700~mbar) but there is no action for this. Only it shows on DCS screen.

  \item[...]

    ...

\end{description}

\section{Low voltage}

The installation or replacement of a Wiener LV Power Supply Unit (in the following called 'PSU') although not too difficult, always imposes the threat of water damage to one or more PSU. In the following section, a few guidelines are given on how to exchange these supplies with a strongly reduced probability of a water spill and subsequent damage. Never work with the LV supplies on your own and ask an experienced person to show you how to do a replacement/intervention. The following sections are thus only meant as a reminder for safety reasons.

\subsection{Equiped racks}
There are two types of PSUs used for the LV of the TRD, either \textit{2 channels, 230 A each } or \textit{3 channels, 150 A each}. Always make sure to use the correct type of supply.
See figures \ref{fig:PSU-Oside1}-\ref{fig:PSU-Iside2} for details.

\subsection{Installation/Replacement of a LV Power Supply}

The origin of the aforementioned threat is the high amount of debris inside the demineralized cooling water, which clocks the self-locking connectors of the PSUs and of the cooling hoses and sometimes water can spill out. Thus the exchange of these PSUs should be planned carefully and must only be done by at least two people. Besides the obvious equipment (i.e. one or more PSU) one should bring the \textbf{bucket, cloth blanket and many paper towels} from the cleanroom to reduce the possibility of a water spill. Further, bring the netbook + USB cable from the cleanroom to access/configure/readout the PSU. 

Before the start of the installation/replacement of a PSU interrupt the power of the rack on the back. \textbf{Make sure this is ok and does not interrupt any other TRD operation!} Now, the inlet and outlet of the cooling for the complete rack must be closed. These two valves are usually located directly below the rack. \textbf{If you do not know for sure which valves are the correct ones, do not operate them and ask an experienced person to point them out to you! } Once the valves are closed for the intervention, return to the front of the rack and remove the ethernet, interlock and power cable of the PSU you want to work with. Then continue with depressurizing the cooling system: \textit{If there is an empty slot in the rack}, locate the connectors of the free cooling hoses inside the bucket and manually open the self-locking valve of the hose by pushing in the plastic part of the connector. Make sure the bucket is covered i.e. with the cloth blanket, so no water can spill out of it due to the high pressure. This should be done for he inlet and outlet hose!  \textit{If no empty slot is available in the rack} you should cover up the PSU below the unit you want to replace as good as possible (paper towels, cloth blanket). Place additional paper towels directly under the valves you want to open. Whereas one person holds the bucket and further towels into position, the other person opens the PSU valves \textbf{simultaneously} by pushing the brackets of the respective valves upward, and then pulling out the hoses.  Proceed by depressurizing the cooling system via the hoses as described above. Remove any water sprinkles! Always keep an eye on the free cooling hoses, as they are typically leaky. \\ 
Now, you may replace/install the PSU. \textbf{Make sure to check that there is a black rubber sealing ring at the hoses' valves. These must not be damaged at all!} Cooling services, ethernet and power cable should be reconnected, the \textit{INTERLOCK} should be set to '\textit{ON}'. \textbf{The pins of the interlock connector are very fragile, thus be very careful during reconnection of the corresponding cable/connectors.} \\
Once the supplies in the rack are reconnected, you should open the main cooling valves again. \textbf{Check again that there are no leaks and water spills!}. Now, the rack can be powered again. Make sure to note down all necessary information of the new PSU (MAC address, location). You should further use the small netbook from the cleanroom to set the IP address to 0.0.0.0. with the Muhse tool. Do not forget to cleanup the paper towels. In case you replaced a PSU, put a paper label with information on the problem, MAC address and former location. \\
\textbf{
AFTER THE INTERVENTION YOU MUST NOT FORGET TO OPEN THE RACK MAIN COOLING VALVES AGAIN! \\
NEVER OPERATE ANY PSU IN THE RACK IF THERE IS THE SLIGHTEST SUSPICION THAT ANY AMOUNT OF WATER MIGHT HAVE SPILLED INSDE A PSU!
}

\subsection{DCS registration} 
There are two databases which should be updated once the PSU was moved:
\subsubsection{TRD gate database - http://alice.physi.uni-heidelberg.de/trd-db/}
Here, the information of the corresponding PSU inside the 'Wiener PSU Search' section should be updated. Further, you in the 'LV bin search' section you should find the IP address of the bin you used. \textbf{Note, the IP is fixed to the bin, not to the PSU!} Thus central DCS coordination must be informed about the changed MAC address for the given ip, as explained in the next subsection.
\subsubsection{DCS database}
A list including the MAC address and the bin IP and alias ('alidcswieXXX') address of all changed PSUs should be sent to central DCS coordination. Currently (04-28-2014) the responsible person is \textit{Peter Matthew Bond - p.bond@cern.ch}. Always cc the mail at least to the TRD technical coordinator and also the TRD operations mailing list.

\subsection{Final Tests}

If everything was done correctly, after a short period of time the PSU should show up green inside PVSS (LV $\rightarrow$ PS network). You may further directly check via 'snmp' if the PSU is correctly registered. For this, log on to 'pcalitrd00' and further on 'wn8'. Here, execute the command 'snmpwalk -v 2c -m +WIENER-CRATE-MIB -c public alidcswieXXX crate' and all information are printed, including the the MAC address of the PSU for this alias.
