Chapter 4: Logging Functions Technical Overview
KW Log (Optional)
The KW Log is an optional daily log included when the KW Monitoring option is included in
the system. It is used to record the periodic totals for Demand KW, Peak Demand, and
Daily, Weekly, Monthly and Yearly usage. KW Log entries are made at midnight each day.
The KW Demand totals are reset as appropriate. The Daily KW is reset each day, the
Weekly KW is reset at the beginning of each week on Sunday morning, the Monthly KW is
reset when the month changes and the Yearly KW resets when the year changes.
System Log (Optional)
The System Log can only be utilized for a system whose Master panel is configured for
communication with an M&M Refrigeration, Inc. PC Monitor™ program. When this option
is active, the System Log will track and accumulate all system data such as analog, dis-
crete, alarm and some status information. This information is held by the Master panel
until a scheduled or user initiated download occurs. At that time, all system information
held by the Master is downloaded to the PC Monitor.
The PC Monitor program must have the Reports or Graph Plotting options in order to utilize
the System Log information. For more information about using System Log data, please refer
to the M&M Systems PC Monitor User’s Manual.
