Possible alarm for LN2 dewar 8514376 (storage for CP2)
CP2's liquid nitrogen storage tank (tank 8514376) may go into alarm sometime before its scheduled delivery on Tuesday. I've forgotten the current alarm level setpoint (had been <20% in the past). This is anticipated and as the result of missed deliveries due to "snowmageddon".
NO ACTION is required by the operators should this go into alarm.
Cell phone alarms will activate when CP2 Dewar level goes below 15%. Since it is already down to 19% I've bypassed this alarm through to Tuesday afternoon.
Bypass will expire:
