Siemens Building Technologies Maximum demand control CK1N9850en
Building Automation 17.08.2001
Features
Optimization and parameter-setting procedures ensure that:
• Only as many electrical loads are shed as is actually necessary to avoid exceeding
the maximum demand limit
• The number of switching operations, and hence, interruptions to the process, is kept
as small as possible
• Action is taken as late as possible, but as early as necessary.
• Load-shedding based on priority is distributed evenly over 16 possible priority
classes.
• Only as many electrical loads are enabled as are necessary to ensure that if the
average power consumption remains constant, it will not be necessary to disable
loads in the next measurement cycle.
Up to four different tariff limits are supported. It is possible to switch from one to the
other on a time basis or via pulse control.
With all switching operations, the maximum demand control program takes account of
the current state of the electrical loads in the process:
• Switch state of electrical loads
• Operating state of the electrical loads (Fault, Manual, Automatic)
• Minimum and maximum switch-off times, minimum switch-on times and off periods,
and maximum switch-off frequency per day, documented in the following reports:
• Report on deviations from capacity (consumption report)
• Prognosis
• Report on switching operations
and provides on-line statistics in graph form, showing the consumption characteristics.
The maximum demand control program can be used for all types of energy where the
load can be controlled via SICLIMAT X, provided that the energy supply can be
measured with sensors suitable for SIMATIC.
