R-SENSOR
OFF POINT
ADJUSTING
OPTION
1) R-SENSOR OFF POINT can be adjusted by changing the input voltage of MICOM 26
pin.
2) The default of input voltage is 0V.
3) The changed OFF POINT is base OFF POINT + OFF POINT of input voltage.
4) The change of R-SENSOR OFF POINT depend on the input voltage of MICOM
