The disturbance recorder can be configured with PCM600 only.
The disturbance recorder can be enabled or disabled with the Operation parameter under .
One analog signal type of the protection relay can be mapped to each of the analog channels of the disturbance recorder. The mapping is done in Application Configuration in PCM600. The name of the analog channel is user-configurable. It can be modified by defining a new name to the Channel id text parameter of the corresponding analog channel. Channel id text can be edited in Application Configuration by selecting the input channel and defining a new Instance Name for the channel in the Object Properties pane.
Any external or internal digital signal of the protection relay can be connected to the binary channels of the disturbance recorder. These signals can be, for example, the start and trip signals from protection function blocks or the external binary inputs of the protection relay. The connection is made with dynamic mapping to the binary channel of the disturbance recorder using, for example, Signal Matrix of PCM600. It is also possible to connect several digital signals to one binary channel of the disturbance recorder. In that case, the signals can be combined with logical functions, for example AND and OR. The name of the binary channel can be modified by defining a new name to the Channel id text parameter of the corresponding channel. Channel id text can be edited in Application Configuration by selecting the input channel and defining a new Instance Name for the channel in the Object Properties pane.
The recording always contains all binary channels of the disturbance recorder. If one of the binary channels is disabled, the recorded state of the channel is continuously FALSE and the state changes of the corresponding channel are not recorded. The corresponding channel name for disabled binary channels in the COMTRADE configuration file is Unused BI.
To enable or disable an analog or a binary channel of the disturbance recorder, the Operation parameter of the corresponding analog or binary channel is set to "on" or "off".
The states of manual triggering and periodic triggering are not included in the recording, but they create a state change to the Periodic triggering and Manual triggering status parameters, which in turn create events.
The TRIGGERED output can be used to control the indication LEDs of the protection relay. The triggering of the disturbance recorder sets the TRIGGERED output to TRUE. The output remains in this state until all the data for the corresponding recording has been recorded.
