Value to alarm check

Select the value types (VOLUME or ENERGY) that will be used for alarm checking.

Percentage Deviation Check

The system generates alarms based on when the projected volume or energy deviates from the nominated volume or energy.

Select Percentage Deviation Check to generate a HiHi (HighHigh), Hi (High), Lo (Low), or LoLo (LowLow) alarm when the difference between the nominated and projected volume exceeds or falls below the alarm limit percentage deadband, as configured in the Level Alarming section.
