<li> Nerses is working on the <a

title="Alarms for voltages (Nerses)"> scheme to generate
alarms for voltages </a> in EPICS. </li>
<li> He showed the logic he is currently considering. </li>
<li> There was a suggestion to have an alarm when the voltages
are set to be off, but they are still on, </li>
<li> Orlando pointed out that there will be a delay between the
moment the setpoint is set and setpoint is readback. This time
delay needs to be taken into account.
</li>

<li> Dave reported significant <a

the BCAL interlocks </a> . </li>
<li> Upstream is wired and tested. Downstream interlock is in
progress. </li>
<li> Downstream chiller is not connected as of today. Will be
connected most likely by the end of today. </li>
<li> Buttons need to be change to match Elton's convention .
</li>
<li> Hovanes asked Elton if the expert GUI that Dave has will
need to be copied to EPICS or EPICS will need to have only a
GUI for the shift personnel with very limited personality.
This was followed by a discussion about the need to have a PLC
in the counting house. </li>
