6.3.15.3 External source mode
6.3.15.3.1 General
The external source mode is basically running like the internal source mode but the mains
measurement, the MCB and GGB control is provided by an external control. This control,
usually an ATS control (e.g. DTSC-200), sends the mains power and required condition
flags as CANopen TPDO messages to the easYgen device. Through configuration of the
RPDO in the easYgen the mains power and the condition flags are appearing
automatically in the LDSS PL function. The system allows to connect up to 5 ATS controls.
We recommend to ask Woodward for a dedicated application note with configuration
examples, if you want go for the external mode.
The external mode contains up to 5 independent “5-minute average value [kW]”
calculations. Out of these values "10.78 Average load sum [kW]" is provided.

The principle of the LDSS PL in external source mode
Pre-assumption
The explanation here is performed for an application with one ATS control. The principle is
expandable on up to 5 ATS controls.
The LM 12930 "LD start stop" is TRUE.
The parameter 9066 "Predicted load source" is configured as "External".
The LM 15026 "LDSS with predicted load" is TRUE.
The ATS control sends:
