Disturbance recorder
1)
M1 can be used for broadcast triggering by using the unit address “900”.
2)
Parameters can be written when the recorder has not been triggered.
3) The disturbance recorder requires this parameter to be set. The conversion factor is the transforma-
tion ratio multiplied by the rated current of the relay. If this parameter has been given the default value
0, dashes will be shown on the LCD instead of the primary values and the recorded data will be redun-
dant.
