<div class="logentry node-content">
Since we have put two GEM modules on Ar:CO2:Isobutane, and they are getting gas from the BB gas system, I have added a new alarm for the BB gas manifold presure. The low alarm is set to 140 psi and lolo is at 135 psi. It should turn off the GEM HV when it hit LOLO.<br />
<br />
I have also modified the CheckGemGas script, which is part of the shift check list, to check the BB gas system as well.<br />
