9.2.5 KW Demand Log

Press the METERS pushbutton on the main menu bar to display the Unit Meter screens. Scroll through the meter screens using the or pushbuttons on the menu bar until the KW Demand Log Summary screen is displayed.

NOTE The KW Demand Log is available only when the mini-CSB is installed.

The KW demand log collects information on events where the unit load exceeds a user-defined KW limit within a user-defined time interval. The user can choose a time period up to 9999 minutes and a load limit up to 9999 KW. If the limit is exceeded within a given time period a log event is created. The KW Demand Log Summary screen displays the number of total times the limit has been exceeded since the last log reset, the date of the last log reset, the maximum KW reading, and the total time over the limit. It also displays the average KW over the limit and an estimated number of KWH used over the limit. Both of these values are calculated using the difference between the actual measurement reading and the user-defined limit level. For example, during a 60-minute interval if the limit is set at 10 KW and the measurement is a constant 15 KW for the entire period, the average KW over would be 5 KW and the total KWH used over the limit would be 5 KWH. Figure 9-13 shows the KW Demand Log Summary screen.
