FYI, the air cooling system does not monitor anything, it only
supplies signals to the cRio analog inputs. The cRio and EPICS
monitor all transducer output signals.<br>
<font color="#ff0000">Bullet 2</font><br>
FYI, the air cooling system does not monitor or shut anything down.
The cRio monitors the cooling system parameters, air pressure, air
flow, and compressor power. The cRio is programmed to turn off the
HV and LV under certain conditions and prevent HV and LV operation
if certain conditions are not met. Those conditions are the
interlocks system parameters.<br>

Bullet 2 </font><br>
FYI, the N2 purge system does not set off any alarms. The RICH N2
flow and internal H2O levels are monitored via cRio and EPICS. The
EPICS Alarm Handler would be programmed to have an alarm condition
if the flow or H2O concentration go out of the normal range.<br>

<pre wrap="">Hi All,
Please take a look to the attached documents: ESAD, THA and OSP.
We need to write OSP because the highest risk code BEFORE mitigation is 3.
It is the rule. The comments are very welcome.
Regards,
Valery
