Parameter Values (Range) Unit Step Default Description
Operation 1=ON
0=OFF
1=OFF Operation on/off of loop control
LCM mode 1=Sectionalizer
2=Mid point
3=Tie point
4=Disabled
4=Disabled Loop control functionality operating mode based on the recloser
type
Dead bus threshold 0.001 … 2.000 xVn 1.000 Voltage level setting (RMS line to neutral) for detecting dead bus
Live bus threshold 0.001 … 2.000 xVn 1.000 Voltage level setting (RMS line to neutral) for detecting live bus.
Dead bus time 1…600 seconds 5 Time duration that voltage should be below the threshold to
determine the bus is dead.
Live bus time 1…600 seconds 5 Time duration that voltage should be above the threshold to
determine the bus is live.
Volt regain time 0…5 seconds 0 When the voltage is lost on a line and the deadbus time is
running, if the voltage comes back above the live bus threshold
for this amount of time, the dead bus timer will reset.
Line side src 1=S1
2=S2
1=S1 Line side source
Vt config line 1 … 3 3 Number of Voltage channels on line side
Vt config load 1 … 3 3 Number of Voltage channels on load side
Vt line enable 1=TRUE
0=FALSE
0=FALSE To include the voltages on line side for making decisions
Vt load enable 1=TRUE
0=FALSE
0=FALSE To include the voltages on load side for making decisions
Vt line phase 0=PhA
1=PhB
2=PhC
0=PhA The connected phase if one voltage channel is used in line side.
Vt load phase 0=PhA
1=PhB
2=PhC
0=PhA If one voltage channel is used in load side which phase is
connected
Sect3POpmode 0=All Phase
1=Any Phase
1=Any
Phase
Single or three phase operational mode (valid only in
sectionalizing mode)
En set grp chg 1=TRUE
0=FALSE
0=FALSE Setting group switching is enabled (Valid for Tie point and mid
point mode only)
Reset on power up 1=TRUE
0=FALSE
0=FALSE Reset on power up setting (valid only in sectionalizing and
midpoint modes)
Sectionalizing reset 1=TRUE
0=FALSE
0=FALSE Automatic resetting of loop control in sectionalizing mode
SWOTF time 0….120 seconds 5 Switch on to fault time to operate the mid point recloser in lock out
mode or non reclose mode after the loop control sequence is
initiated.
