[Kira, Gautam]
We began the setup for the lab temperature sensor today. First, we needed to add in a DIN fuse for both temperature sensors, which required us to shut down everything else first. To avoid having to do that next time, we made three instead of two spaces where we have + and - 15V. Attachment 1 shows the new fuses we installed, along with the fuses they connect to. Attachment 2 shows the wiring that we used to connect all the fuses. Attachment 3 shows the labeled long wires that are attached to the lab temperature sensor. The other end is labeled as well. I measured the voltage at the other end of the long cables, and while the -15V one looks good, the +15V one shows only about 13.5V.
-----
edit (Tuesday) - I set up the other set of cables that will eventually lead to the sensor in the can, but neither of them are showing any voltage on the other end. I'll work on this issue tomorrow.
gautam: some additional remarks about the procedure followed:
- Wires were tinned with solder to facilitate easier insertion into DIN fuse blocks.
- ETMX watchdog was shutdown. I then unplugged the satellite box at the X end to avoid any sort of electrical impulse being sent to the optic.
- Shut down all the sorensens in the EX rack.
- Tapped new +15VDC and -15 VDC outputs at the EX rack in the locations Kira indicated.
- Turned Sorensens back on. Checked that all voltages as reported by front panel monitor points were as they were expected to be.
- Had some trouble getting the modbus IOC going after this work. Kept throwing an error that modbus couldn't be initialized by procserv. Ended up having to reboot c1auxex2, after which it worked fine.
