4. Control relay setup
A wide range of setting options are pro-
vided to enable the reactive power con-
trol relay to be used in the widest possi-
ble way. To simplify matters the control
relay is set to standard values in the fac-
tory (see table 1 below).
This means that the user mostly only
needs to change the target power factor.
The setup mode can be reached from
any of the control relay’s operating
modes.
