Configuring the System to Report on Intervals Outside Acceptable Bounds

DC 2009 allows you to set up a simple, yet extremely effective, Central Interval Level Checking scheme that enables you to report on intervals outside user-configured boundaries. You can configure this tri-level checking scheme for both High and Low Intervals; however, you are not required to use both.

Let's assume you have a customer that is "interruptible" (curtailed). Of course, you cannot completely shut the gas off because the customer has a large number of pilot lights that must remain operative; therefore, a very small consumption is expected. You could set up the following tri-level central interval high checking scheme:

Central Interval 1 High - Set this to the lowest level of severity. If consumption rises above this level, monitor this customer more closely.
Central Interval 2 High - Set this to the middle level of severity. If consumption rises above this level, call the customer.
Central Interval 3 High - Set his to the highest level of severity. If consumption rises above this level, you know that the customer is using gas.

To configure the system to report on intervals outside acceptable bounds using a central interval level checking scheme:

Open the Remote Unit Configuration application.
In the Available Remote Units list, select the Remote Unit.
Use the Search Engine utility to find a particular Remote Unit or group of related Remote Units
Click the Edit Icon.
The View Remote Unit dialog box appears.
Click the Input Description tab.
In the Remote Unit Inputs list, select the input that you want to set up and click the Configure button.
Click the Central Feasibility tab.
Select the Highs check box.
The Central Interval 1, 2,, 3, & 4 High lists and Limits boxes are enabled.
You can change the alarm description for any of the Central Intervals by clickign the arrow and selecting an alarm description
from the list.
In the associated Limits box for each Control Interval High Level, assign a value.
You should know the units in which the selected input is monitoring when you set the high limits and the low limits.
Click OK.
