T-814 Level Alarms The M1 storage vessel T-814 has two level transmitters and a scam high level alarm that is hard-wired from one of the transmitters to the annunciator panel. However, the transmitters are not accurate because the nitrogen repeater is faulty. Therefore, the scam alarm and TDC alarms arc falsely activating. The correct level in T-814 is calculated on the PicsVax based on the top and bottom pressures. The scam alarm will be disconnected, and the TDC alarms will be removed. The level will be calculated on MOD5 as well as on PicsVax, and the level reading from PicsVax will be sent to GPI. Low, high, and high-high level alarms for both level readings will be set at 20%, 75% and 85% respectively. All alarms will be displayed on GPL Let me know if there are any questions.
