Description
Set_Demand_Interval
The value, in minutes, used to calculate the End of Demand Interval (EOI). This value is used only if the Val_End_of Demand_Type is 2.
Set_Demand_Delay
The time value used to reset the end of interval after the Set_Demand_Interval value has been exceeded without a utility contact or master
end of demand contact closure. The value must be between 0…90 seconds.
Set_End_of_Demand_Interval_Type
The value that defines how the End of Demand Interval (EOI) is triggered.
1 = A local digital input connected to an electric utility meter EOI contact (Inp_End_of_Demand_Utility_Contact).
2 = An internal PLC timer (Demand_Interval _PLC Timer) that is typically used when an electric utility meter EOI contact is not available.
3 = A master command input (CMD_Master_End_Of_Demand_Interval) typically from a central controller that is used to synchronize
multiple electric meter EOIs.
Set_High_Demand
When the demand (kW) value exceeds the Set_High_Demand, the High Demand Fault is set.
Set_Critical_Demand
When the demand (kW) value exceeds the Set_Critical_Demand, the High Critical Fault is set.

Definitions
Set_Calc_Interval
The time interval, in minutes, used to calculate the average energy flow.
For example, an interval value of 5 will calculate the average energy flow every 5 minutes.
Set_High_Flow
When the flow rate value exceeds the Set_High_Flow value, the High Flow Fault is set.
Example: A value of 1000 will set the High Flow Fault in the Energy_Gas_PM_Status Add-On Instruction when the gas flow rate
exceeds 1000 therms/hr.
Set_Critical_Flow
When the flow rate value exceeds the Set_Critical_Flow value, the Critical Flow Fault is set.
Example: A value of 1500 will set the Critical Flow Fault in the Energy_Gas_PM_Status Add-On Instruction when the gas flow rate
exceeds 1500 therms/hr.
TIP
The meter pulse factor, consumption value of each input pulse, is set within the PowerMonitor configuration. Refer to
