Flexible protection functions
(parameters from current and voltage):
Voltage protection, power protection,
power factor protection, frequency change protection
and
voltage change protection
1)
depending on the ground current input at position 7, the function works either as ground fault protection (sensitive
input) or as ground short circuit protection (normal Ie input)
2)
only with sensitive input, Position 7=2
3)
only deliverable with position 6 = 1, 2 or 7
4)
only deliverable with position 6 = 3, 4 (3 x V) or 8
5)
only deliverable with position 6 = 3, 4 (3 x V) or 8 and position 16 = 0 or 1
