Comm Port

Communication Port. An access point for data entry or exit.

Crit Hi Level

Critical High Level alarm set point. When the product level exceeds this point a critical alarm is generated.

Crit Hi Temp

Critical High Temperature alarm set point. When the product temperature exceeds this point a critical alarm is generated.

Crit Lo Level

Critical Low Level alarm set point. When the product level drops below this point a critical alarm is generated.

Crit Lo Temp

Critical Low Temperature alarm set point. When the product temperature drops below this point a critical alarm is generated.

oC
