Temporary Level Change for CP5
(John, Gerardo)
CP5 level has been changed from 92% to 84%. This is going to generate alarms since 84% is the low level alarm, please do not ignore alarms below 84%.
CP5 is now in PID control.
I think Gerardo meant to say you can ignore alarms near 84% but if the pump level falls much below that - say 74%; then action should be taken.
If this is the case you may set the liquid level control valve (LLCV) to manual and use the current manual setting of 90%. Or call one of us.
Vacuum staff will have alarm texts sent to their cell phones if the level drops below 80% (or above 99%)
