The SMP main control panel and remote control module were updated in order to implement the following items which were deemed desirable during commissioning:
 

•     24 VDC line added to E-stop circuit:
  
  Previously the E-stop relay cut power to only 120 VAC. This means that the lid rotation motor would stop instantly, but since the lid open/close valve is powered by 24 VDC which comes from a power supply unit, there would be a short delay while the unit powers off in which the valve was still active. This could result in a situation in which, for example, someone is operating the pendant to close the lid and another person recognizes a hazard and presses the E-stop on the main panel, but the lid does not stop closing for approximately 3 seconds while the operator is still holding the "close" button down.
  
  To rectify this issue, the 24 VDC line was routed through a NO contact of the same E-stop relay that controls the entire 120 VAC supply to the system. This was tested on Oct. 25, 2019 - working.
  
   
• Status feedback signals to remote control room:
  
  Previously status signals for "Lid raised", "Lid Centred", "CW Limit", and "CCW Limit" were only displayed as light indicators on the main control panel. It was determined during remote operation that it would be helpful to have these signals sent back to the software interface so that an operator does not need to use a camera to look at the light indicators.
  
  
  Electrical drawings and cable schedule have been updated to reflect these changes. The SMP will be tested again using the commissioning plan checklist to confirm no there were no inadvertent effects on the rest of the same from these changes.

The SMP assembly was shifted approximately 1.0" north today by pushing it, braced against the south wall, using a 100 Ton capacity air lifting bag supplied by Beamlines Group.  The move was one of the action items identified at the Gate 4A/4B close-out review.  During commissioning of the SMP, TM3 was installed into the vacuum vessel, which required the crane to be all the way at its south limit, so the move is to provide some margin for future use, particularly if TM1 is put in the SMP as the extent of its shielding is slightly larger than the other modules.

One of the air fittings for the lid actuation cylinder on the north side was damaged during the move.  It was replaced and correct functionality of lid actuation was then confirmed.

 TM#2 with SiC#39 has been moved from the east station to the smp.

TM2 in SMP with old SiC #39 target on it. SMP vacuum pump is started.

Frank and I removed TM2 from SMP to SHC. The move is successful.

Sorted and packed one 55 gallon drum with low contamination and active stuffs which are placed around silo area in the past. They include old poly water cooling lines replaced from ITE, ITW and TCS, contaminated paper  rags , gloves, and plastic bags,air cooling fans for turbo pumps, EE resistor packaged used on module top before, flow meters and cables used in ITW, etc. After packing, The field outside the drum on contact is less than 10 usv/hr.

Dan and I did the SMP annual  maintenance service today. Lid open/close , vessel rotation and limit switch check, lubricate chains, tighten fasteners, and visual inspection.  Everything works fine.

An electrical systems check was performed on the SMP by Adam Newsome and Travis Cave. Overall, there were no issues to note. The following is a summary of the inspection (Work Permit I2020-07-16-1):

- Checked condition of wiring for physical/radiation/UV damage
- Checked for cable tray debris or damage
- Checked inside control panel: components and wiring, labeling
- Verified camera views
- Checked connectors for damage
- Checked pendant for damage and verified labeling intact
- Checked limit switch wiring and condition

 TM#2 with Nb#9 was moved from ITW to SHC and then with no target it was moved from the SHC to the SMP.

 TM2 at SMP under vacuum. TM4 at silo.  Frank and I did the tests. Everything is fine on TM4 check.  On TM2,  all mega test at 500V are around 200K ohms which is so abnormal. We will move TM2 to TCS and  start investigation there.
