The circuit breaker condition monitoring function includes different metering and
monitoring subfunctions. The functions can be enabled and disabled with the
Operation setting. The corresponding parameter values are “On” and “Off”. The
operation counters are cleared when Operation is set to “Off”.
The operation of the functions can be described with a module diagram. All the
modules in the diagram are explained in the next sections.
