That's great!. Does this mean we are ready to start operating the heater system? If so, I would like to meet you to go over the controls/monitoring program again. Also, Ed Folts requires that we <span style="font-family: Calibri, sans-serif; font-size: 14.6667px; display: inline !important; color: rgb(0, 0, 0); background-color: rgb(255, 255, 255);" class="ContentPasted0">call
Robert Miles to monitor the VESDA instead of us doing it at the heater startup, so I would like to get that coordinated soon.</span></div>

<p>Completed debug of the ECAL six-supermodule test stand monitoring thermocouples. All 16 thermocouples readback.</p>
<p>Installed a watchdog relay which monitors the controls software heartbeat and will remove power to the heaters if the controls heartbeat is not present for 30 seconds. The interlock is cleared when the software heartbeat returns.
</p>
<p>This relay is independent of the cRIO controller and the Omega process controller (over-temp monitoring).</p>
