bypassing CP4 REGEN Interlock alarm until Monday
Kyle confirmed that the CP4 regen overtemp interlock alarm will be in the alarm state from now through Monday. I have bypassed this channel from sending cell phone texts until that time. Email alerts for this alarm will continue to be sent.
CP4 TE253A, which is currently following the ambient temperature (with ROC alarm levels of +/-5.0 degC per Hour) generated an alarm earlier today when the outside temperature increased at 5.5 degC/hr for a short period of time (when the Sun came out possibly). If this becomes a nuisance we can consider raising the alarm levels.
