<div dir="ltr">Thank you very much for your detailed message about the tests that you, Pablo and Don did on Friday, I really appreciate it.</div>

</div>
<div dir="ltr">That’s great to hear that all pumps and interlock system worked as they should.</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">For testing the downstream turbo pump, we can connect the outlet of the pump to the inlet of Pfeiffer H803 multi stage pump. When all turbo pumps are backed by the Pfeiffer H803 pump, the interlock system will be satisfied. We’ll find the vacuum
parts to modify the connection next week. So the system can be tested again right after.</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">Next week, Donald, Phillip, and/or I will contact James Brock tool get additional information about the system.</div>

We (Pablo, Donald and I) tested the interlock chassis with all four of the turbo pumps operational; can confirm that the chassis will spin down all the pumps when there is a fault and that the 3400 vs 1500 behave differently once the fault is cleared. Not much
of an problem as resuming pump operation requires manually turning them on from the local controllers, so just a procedure/documentation issue.</div>

What was unexpected is that if a pump has a failure itself there doesn't seem to be an easy way to clear the fault. Here's the steps we did.</div>

<div dir="ltr" style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
1 - The downstream pump was connected to power/controls, but didn't have any backing vacuum.</div>
<div dir="ltr" style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
2 - When turning on the pump it eventually failed with error code 6 which is related to a startup timeout, this in turn generated a failure on the interlock chassis. So far so good, pump protected itself and the interlock chassis put the system into a safe
state.</div>
<div dir="ltr" style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
3 - With the interlock chassis actively indicating a fault there now is no way to actually clear the error on the local controller as it is in remote mode.</div>
<div dir="ltr" style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
4 - We had to disconnect the interlock cable to that pump to prevent it from going in remote mode, which allowed us to clear the fault on the pump controller. We also installed a jumper on the status output to the interlock chassis for that pump, but I suspect
that wasn't actually needed.</div>

<div dir="ltr" style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
I'm not sure this is a state the system or interlock chassis was intended to handle. All the other faults we've tested allow the system to immediately run again once the fault is cleared.</div>

While it would be nicer if there was a clear or bypass button as far as we can tell that doesn't seem to exist, but since it is possible to clear the error and eventually run the system again I don't think there's much to do about it.</div>

I will find out the status of modifying power distribution box and let you know. For powering the 3400 and 1500 pumps together, can I "borrow" the outlet for the cold head compressor to power the extra pump? Does the interlock care about that? I'll be working
at ESB after 2:30 this afternoon for some cabling issues.</div>

There is one interlock that checks the compressor which is labeled at its inlet connector as "cryo-compressor", I'm not sure if that is the compressor that you're referring to. If this is the same compressor, we could try to find a way to force a clear input
by wiring the input connector and proceed with the test.</div>

I cannot answer about using the compressor outlet for the vacuum pump since I do not know electrical specifications required, this might be answered better by Donal Williams or another involved person working on the modifications for the power distribution.</div>

I will find out the status of modifying power distribution box and let you know. For powering the 3400 and 1500 pumps together, can I "borrow" the outlet for the cold head compressor to power the extra pump? Does the interlock care about that? I'll be working
at ESB after 2:30 this afternoon for some cabling issues.</div>

We need more testing as the vacuum pump controllers model 1500 vs 3400 behave differently—the 1500 can run right away after interlocks are cleared, but for the 3400, the remote mode setting needs to be modified to run them again.</div>

To be able to test 3400 and 1500 vacuum pumps at the same time we have requested to power them on and we have been informed that required electrical components are being ordered and will need to be installed prior to this intent; DSG is waiting on this to proceed
