Acquiring the Open/Closed Status of the Gate Valve Between PRM and PR3

[ Yasui, Oshino, Nakagaki ]

We have installed a system to monitor the open/closed status of the manual gate valve between PRM and PR3.
The open/closed status is provided via the following PVs:

K1:VAC-GV_PR3_OPEN
K1:VAC-GV_PR3_CLOSE

These have also been added to the `VAC_OVERVIEW` MEDM screen.

Since we were unable to test the valve in the closed position today, we will conduct that test at a later date.

We tested the device for acquiring the open/closed status of the PRM-PR3 gate valve and confirmed that it operates correctly.
