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
menu bar until the kW Demand Log Summary screen is displayed.
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 8‐13 shows the kW Demand
Log Summary screen.
