keyword=Switched to cold return. A few items fixed.
Just completed switch from warm return to cold return. The procedure from MCC point of view is completed. We will need to continue liquifying hydrogen and deuterium for another hour or so, then get it stable, setting up to the normal operation conditions.
Chris Keith fixed the problem with the diode readings by plugging back two cables.
The fan control remote was not working. Turned out we need to have the third fan controller (not in use) to be power up to get the communication working properly.
The Tachmeter readings were all show 0. Again they were due to cables not connected (at the target side). Dave connected them. They are working now.
