Pr.37: Current Fuses Enable/Disable:
If any phase current exceeds 1.5 times of high
current protect value, or ,if any phase current decrease 0.5 times of low voltage protect
value, the relay switches off instantly. At position disable, current fuses function is
cancelled.
Default:
Disable,

Pr.30: Current Asymmetry Protection Value
:
Determines the controlled current
asymmetry.
Asymmetry Ratio Adjusment:

Min:
%5,
Max:
%50
Pr.31: Current Asymmetry Protection Delay Time
: Determines delay open time.
Delay time for activating the output. If calculated asymmetry value below the current
asymmetry protect value, Relay output switches open at the end of delay time.
Default:
3sec,
Min:
1sec,
Max:
10000sec.
Pr.32: Current Asymmetry Protection Reset Time:
Determines delay close time.
If calculated asymmetry value over the current asymmetry protect value as a hysteresis
current, relay output switches close at the end of the reset time.

10sec,
Min:
1sec,
Max:
10000sec.
Pr.33: Current Asymmetry Protection Hysteresis:
Required hysteresis current for
current asymmetry warning is programmed.

Max:
Enable
Pr.35: Current Auto Reset Enable/Disable
:
If auto reset enable and system into error,
if all current are over/below the protect value as hysteresis value ,relay output switches
on at the end of the Reset time. If Auto reset is disable, after all current are over/below
hysteresis value, relay output switches manually. (Using ESC button).
