Optional Load Profile Recording Function
Load profile recording is an optional selection when the BE1-CDS220 is ordered. The Load Profile, 4000
Point Data Array option (Y as the third character from the right in the style chart) uses a 4,000-point data
array for data storage. Refer to Section 1, General Information, Model and Style Number Description, for
more information on optional selections. At the specified (programmed) interval, Load Profile takes the
data from the demand calculation register and places it in a data array. If the programmed interval is set
to 15 minutes, it will take 41 days and 16 hours to generate 4,000 entries. Load profile data is smoothed
by the demand calculation function. If you made a step change in primary current, with the demand
interval set for fifteen minutes and the load profile recording interval set for one minute, it would take
approximately fifteen minutes for the load (step change) to reach 90 percent of the final level. See the
previous paragraphs in this section on Demand Calculation and Reporting Function, for information on
calculation methods.
Setting the Load Profile Recording Function
For the load profile recording function to log data, you must set the demand logging interval. This can be
done from the ASCII command interface using the SG-LOG (setting general, logging interval). Table 6-6
lists the settings for the optional load profile recording.
Table 6-6. Load Profile Recording Settings
Function Range Increment Unit of Measure Default
Demand Log Interval 1 - 60 1 Minutes 15
SG-LOG Command
Purpose:
Read/Set load profile interval
Syntax: SG-LOG[={interval}] where interval is between 1 and 60 minutes
SG-LOG Command Example:
Example 1. Set the demand logging interval to 12 minutes.
>SG-LOG=12
Retrieving the Load Profile Recording Function
Load profile recorded data is reported by the ASCII command interface using the RD-LOG command.
You may request the entire log or only a specific number of entries.
RD-LOG Command
Purpose:
Report load profile data
Syntax: RD-LOG,<n>
Comments: RD-LOG by itself reports all records in the 4,000-point data array. RD-LOG,23 reports the
last (most recent) 23 records.
RD-LOG Command Example:
