[Dsg-rich] 1 MINOR alarm(s): GAS

[Tyler Lemon]

Hello Valery, 

Those alarms seem to be a consequence of the RICH Gas Alarm limits for "N2 flow 1" and and "N2 flow 2" not being updated for after yesterday's installation of the upgraded N2 panel. 

Attached is a screenshot showing these limits. 

The new panel uses only N2 Flow 1, which is set to 40 slm to give the same total flow as the old panel. Increasing alarm limits should fix alarms like the one you just received (boxed in blue in attached screenshot). 

With the upgraded panel, we are no longer using N2 Flow 2. These alarms can be disabled (boxed in pink in screenshot). 

Once the alarm limits are updated to account for the new flow values with the upgraded panel, the alarm notifications should stop. 

Best regards, 
Tyler
