A cable track was installed between the mini-storage vault and the silos, for the purpose of implementing a retractable cable chain (e-chain). This will allow for cables to be managed during door opening/closing, so that remote control operation of the door will be possible in the future. See Work Permit I2021-08-11-2 (Aug 11)

Holes were drilled into the motor mounting plate (IRH2089) to allow for mounting a limit switch on the plate. See Work Permit I2021-08-17-7 (Aug 17)

Preliminary testing was completed in which the e-chain was fixed to the door with a C-clamp. Local and remote functionality were checked, and limit switch functionality was verified. Everything is working as expected. A final test will be conducted once the e-chain is fixed to the door and cabling routed through it. See Work Permit I2021-08-19-1 (Aug 19)

The e-chain has not yet been fixed to the vault door - holes will be drilled in-situ after preliminary testing is complete to confirm positioning.

 Edit [2021-09-23]: the installation is complete and has been tested.
