Setting up parameters
Setting up, query and test functions can be achieved through
operations on the keys on the controller panel, such as “Function
”, , , “Enter
”, and “Return
”.
Press the functional key to cycle through the three states for
selection: setting up, query, and test; press and keys to
select a functional option or increment/decrement a parameter
value; press the “Enter” key to enter into the functioning state
or save the changed data; press the "Return" key to return to the
previous operation.
Step 1: Press the functional key until the “Setup” indicator is
flashing. Press the Enter key again. At this point, the “Setup”
indicator is still flashing, while an indicator for a specific protection
type is lit on, indicating entrance into the value setting up state.
Step 2: Press and keys to cyclically display the original set-
ting data of each setpoint. To modify a certain set point, press the
“Enter” key and the “Setup” indicator will always be lit on. Adjust
it with and keys until the required value is reached. Press the
“Enter” key and the “Save” indicator will be lit on once, indicating
that the modified value has been saved. Press the “Return” key to
exit the modification of the set point.
Step 3: Repeat Step 2 until all the set points are modified. Press
the “Return” key to exit the setup function.
To modify the set points of each protection characteristics, refer
