    keyword=Work around for LHRS hut doors

    Jack came in and reprogrammed the controller again. It seems that it can no longer reliably store settings in its non-volatile ram.

    For the moment we will leave the door power on. This is not a good long term solution as the settings will probably get scrambled after some finite amount of radiation exposure. (The scrambling can be fixed with by power cycling the module, but then the doors can't be closed without Jack reprogramming the module again.)

    Jack will swap the left and right door controllers on the LHRS during the next 2--3 hour access. That will let us reliably open and close the critical left door and we will just leave the right door closed.
