TITLE: 01/28 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Preventive Maintenance
INCOMING OPERATOR: Oli
SHIFT SUMMARY:
Maintenance Day roughly ended at noon followed by locking and getting locked fairly smoothly with no issues worth noting.
There has been a temperature drop at EX from this morning due to a heater coil failure. Tyler gave Oli and I a summary of the status of EX's recovery. The Reheat temperature is now up at 80degF (it had been hovering at 60 for the last 7hrs)---it will now oscillate a bit until it returns to normal operations. Tyler said to keep an eye on it and contact him if we loose our Reheat air again.
