Disabled 0
Enabled 1
174.06 Overcurrent instant limit Defines instant DC input overcurrent limit that causes a
fault.
200.0 A/ Real
0.0 … 2000.0 A DC input overcurrent limit. 1 = 1 A/
10 = 1 A
174.07 Overcurrent delayed
limit
Defines delayed DC input overcurrent limit that causes a
fault after the current is over the value for the time
defined in parameter 174.08 Overcurrent time delay.
180.0 A/ Real
0.0 … 2000.0 A Delayed overcurrent limit. 1 = 1 A/
10 = 1 A
174.08 Overcurrent time delay Defines delay time for the DC input overcurrent fault.
The fault occurs when current is beyond the defined limit
for the duration of delay.

Disabled 0
Enabled 1
174.10 Delayed Reverse
current limit
Defines delayed input reverse current limit that causes a
fault after the current is below the value for the time
defined in parameter 174.11 Reverse current time delay.
-10.0 / Real
-100.0...0.0 A Delayed input reverse current limit. 1 = 1 A/
10 = 1 A
174.11 Reverse current time
delay
Defines delay time for the DC input reverse current fault.
The fault occurs when current is below the defined limit
for the duration of the delay.
10.0 s/ Real
0.0...999.0 s DC input reverse current fault delay time. 1 = 1 s/
10 = 1 s

input current.
Warning/ List
No No action selected. 0
Warning 1
Fault 2
174.15 Current deviation delay Sets the duration of how long the current deviation must
be above limit before defined action is triggered.
