WP12123 Alarm system use Twilio for cell texting
Dave:
Because of recent issues with bepex being unable to send text messages to verizon.com for several hours at at time, I created a test alarm system which uses both bepex and our 3rd party texting service Twilio. I will run the old and new alarms side-by-side for testing.
WP12125 CP1 Fill Time Change.
Dave, Janos, Gerardo:
CP1 fills happen at 8am during the summer before the dewar gets full sun and the head pressure increases. This is not needed during the winter, so I've reverted the fill time to 10:00.
Note that after the CP1 vaporizer disconnect work this morning, we did not need a second overfill run.
EX CNS-II independent GPS receiver failure
Dave, Daniel, Erik, Fil
(see Erik's alog for details). At 03:54 PDT this morning the EX CNS-II GPS receiver stopped running correctly:
The 1PPS became a noisy signal with an 8 second repeat.
The IRIG-B signal became a flat noise signal with a 1 Hz spike
The GPS MEDM froze at the last good values.
After its 12V DC wall-wart was replaced it is working agains.
The H1:CAL-PCALX_IRIGB_DQ channel was down between the times

Timing Master port 7 activation
Dave, Daniel, Erik, Fernando
The MSR Timing Master port7 is temporarily connected to a timing card in the spare Beckhoff computer. Normally this computer is powered off.
This morning Fernando powered the computer up for updates. The MFO went into an error, correctly reporting a spurious signal on port 7. To green up the master, I activated port7. When Fernando powered the computer back down I returned the port to its deactivated state.
