Entrance Module was moved from South Hot Cell to ITW Station.

Note: weight of entrance module, as shown via overhead crane's load cell, is 14,900 lbs.

ITW Entrance Module was moved from west station to South Hot Cell.

TM2 was moved from ITW to the Conditioning Station.

Tm2 and itw entrance module have been disconnected in ITW. I will attach disconnection checklist later.

A relay contact-based interface module was installed in between Safety Group's storage vault door enable junction box and Remote Handling's control module for the vault door.

The purpose of this module, which contains a diode bridge and relay, is to isolate the safety system from the control module to prevent back-voltage on the safety system which can damage the PLC's power supply.

In the new configuration, rather than receiving a 24 VDC signal from the safety PLC, this signal activates the relay, whose normally closed contacts supply 24 VDC (from internal) to the safety relay inside the control module. Wiring was modified inside the control module to account for this change.

In investing how to achieve the same functionality as before this change, it was determined that the control module's electrical schematic was not correct and did not reflect the actual wiring. A new schematic was created for this based on the actual wiring, including new changes.

The system was tested by locking out the target hall, and verifying that:
- No failure occurred on the power supply for the safety PLC
- This new relay actuated when the target hall was locked out (i.e. received signal from PLC)
- This new relay correctly supplied 24 VDC to the safety relay within the control module, allowing for the Opto-22 control unit to output control signals to the motors

Note: currently the soft limit switches for the vault door close/open have been bypassed. This is not a safety issue; the door can still be fully opened and closed remotely (but the open override and close override buttons are rendered useless). The bypass will be rectified in the coming weeks and this e-log will be updated accordingly.

Edit (Aug. 13, 2020): the issue regarding the limit switches has been resolved. The entire system is functioning as it was prior to the safety interface installation.

 TM#2 with Graphite #1 has been moved back to the west target station from the conditioning station.

 The West Entrance module has been moved from the south hot cell back to the West Target Station.

Entrance module wire scanner has been replaced. Pictures to follow.

 The West Entrance module has been moved from the west target station to the south hot cell for repairs.

 TM#2 has been moved from the west station to the conditioning station. ITW entrance module moved will take place on Monday morning. 

The emergency close mechanism for the Storage Vault door was tested by Adam Newsome and Travis Cave. The door was opened to its fully open limit, then closed with the emergency system.

The test was successful.

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#3 has been moved from the conditioning station to the silo.

Tested RF from RF driver into new IGLIS wires at ITE. Used 5V, 1MHz (2MHz setting because of internal halving issue).

As expected there was a very slight mismatch visible (original cable ~ 68 Ohms, new cable ~ 53 Ohms).

The matching resistor will be changed and it will be retested.

 TM#3 has been moved from the silo to the conditioning station, where David and Frank will start on the gutting of the module.

Five shielding blocks are transferred to ITW

TM4 has been connected in ITE. Vacuum pumping down is good so far.

 TM#4 with UC#30 has been moved from the south hot cell to the east target station.

Electrical and leak check are good. See attachment.

UCx#30 has been installed onto TM4 with new high current fasteners torqued to 130 in lbs.
