80 Parameters
174.20 Relative threshold Sets the relative string current threshold value.
Below this value the relative difference detection
is disabled. 1 A
0 … 100 A 1 = 1 A /
10 = 1 A
174.22 Blown fuse detection Enables the blown fuse detection. Requires a
fuse board to be installed. Enable
Disable 0
Enable 1
174.23 Blown fuse tolerance Sets blown fuse detection tolerance. 0.1 A
0 … 100 A 1 = 1 A /
10 = 1 A
174.24 Blown fuse active
boundary Sets the blown fuse detection boundary. If mean
current of the corresponding input is below this
value, blown fuse detection is not enabled. 1 A
0 … 100 A 1 = 1 A /
10 = 1 A
174.30 Reverse input current
detection Enables reverse input current detection. Enable
Disable 0
Enable 1
174.31 Reverse input current limit Sets the reverse input current detection limit. 1 A
0 … 1.5 A 100 = 1 A
174.32 Reverse input current
delay Sets the duration for how long the reverse input
current must be above the limit before indicating a
fault. 10 s
0 … 600 s 1 = 1 s
174.35 Reverse string current
threshold Sets the activation power level in percent of the
nominal power for reverse string current
detection. 10%
0 … 100% 1 = 1%
174.36 Reverse string current
delay Sets the duration for how long the reverse string
current must be above the limit before indicating a
warning.
Note : Reverse string current detection is
available only in -SX model.
