Ground fault monitoring thresholds / Gnd flt threshold

Access level: 3
Can be changed: T
Unit group: -
Min:
0.0 [%]
Description: Sets the shutdown thresholds for the ground fault monitoring.
The setting is made as a percentage of the maximum current of the power unit (r0209).
Index: [0] = Threshold at which precharging starts
[1] = Threshold at which precharging stops
Dependency: See also: p1901
See also: F30021
Note
This parameter is only relevant for chassis power units.
