Log Number: 4468712Logbook(s): Body: 

Troubleshooting revealed a bad Terminator AC power supply, a bad Astrodyne 24 VDC to 24 VDC, DC/DC inverter and a bad filament power supply. All but the filament power supply have been fixed. The filament power supply is obsolete and two refurbished power supplies have been ordered; one to replace the bad one and the other as a spare.

CED OTF screens not showing jumpered valves

9 hours 1 minute ago
Log Number: 4468698Logbook(s): Tags: Entry Makers: michaelmBody: 

It appears on-the-fly screens generated from CED (and the analogs) do not place / locate valves on screens if they are disabled / jumpered open (marked in CED as Unpowered = yes as with VBV1C00A) - this creates a potentially dangerous condition for operators or technicians preparing for work or trying to isolated some vacuum region where it is much easier to make potential mistakes in work planning and operations. As with disabled ion pumps, we would request disabled valves always be show in screens.

Log Number: 4468693Logbook(s): Entry Makers: duttonkingBody: 

IR sensors on 0L03-3&4 are GOOD.

(12:03)
Disconnected both IR connectors on CM and cleaned the sensor pins.
Cable connectors and cables in good condition.
Measured 0L03 IR sensors 3&4 on cold cryomodule at 2K.
0L03-3: -38mV; rises to -34 mV with 6V applied to IR test resistor (good.)
0L03-4: -43mV; rises to -39 mV with 6V applied to IR test resistor (good.)
Reconnected cables to proper sensors.
(14:40)
Master Reset of 0L03 shows all CWWT readbacks are now good.
