explanation

Demand Name

Select the demand to display as active.

Displays the operating status of demand monitoring.

❑Monitoring in progress

❑Suspended

Settings Menu

Opens the settings menu. Each time you click the icon, the settings menu will be displayed/hidden.

For information on the settings menu, please refer to "Settings Menu".

Demand Graph

The trend of the demand value is displayed in a graph. When demand monitoring starts, the demand power is plotted over time at each demand update interval. As the counter value (demand tag) of the amount of power registered in the demand settings increases, the graph gradually grows.

In addition, after the "forecast start time" set in the demand settings has passed, a demand forecast line will be displayed. Here, the value at the end of the demand period (the intersection of the demand forecast line and the 30-minute vertical line) on the extension of the demand forecast line will be the forecast demand power within that demand period.

If the demand forecast line exceeds the warning line, a demand warning is detected. The demand warning detection status is displayed in the demand value list. In the following example, the first warning is detected.

❑Normal (white lamp displayed)

❑When an alarm is detected (red lamp displayed)
form_demand_015

When 30 minutes have passed and the demand time cycle has ended, the graph line display of the demand power in the graph area will be automatically reset. When reset, the previous demand graph will be displayed in the graph area and drawing of the demand graph for the new demand cycle will start.

Furthermore, when resetting, if the demand power value for the current demand cycle exceeds the past maximum demand, the bar graph display of the maximum demand on the right side of the graph will be automatically updated.

You can freely change the display style (color, line type, line thickness, etc.) of past demand graphs (last time, the time before last) and display/hide from the demand settings. By default, the last time demand and the time before last demand are set to be displayed.

Demand Value List

Displays a list of demand monitoring information. Each information item is displayed on one line with the color, alarm status (alarm only), name, and unit.

name	Contents	remarks
Contract Demand	Displays the set value of the contract demand power registered in the demand setting.
Target Demand	Displays the target demand power setting value registered in the demand setting.
Current Demand	Displays the current demand power.
Forecast Demand	Displays the predicted demand power value at the end of the demand cycle.
Regulated Power	Displays the difference between the predicted demand and the target demand. For example, if the predicted demand exceeds the target demand, it displays how much kW of power needs to be reduced compared to the target.	Predicted Demand Power - Target Demand Power
Maximum Demand	Displays the maximum value of the demand power measured in the past.	It is initialized to 0 by maximum demand reset.
Past Demand	Displays the historical demand power.	By default, the previous demand and the demand before last are displayed.
Demand Alarm	Displays the demand alarm threshold value and alarm occurrence status.	By default, three alarm thresholds are displayed.
