MMPR-220 motor protective controller change the current to voltage signals through external current transformer, “protective CT coefficient” should be set according to the model of the external 10 MMPR-220 motor protective controller WLD[K]-JY-450-2014 current transformer, the value equals to the one marks as motor rated current on current transformer. Example: The model of current transformer is “Current transformer CT-25M2 10”, primary rated current of motor is 25A, maximum range is 10 times, so the maximum current to be measured is 25×10＝250. Set current transformer coefficient of menu “Current transformer coefficient” to 25.  “DCS parameters setting” Firstly, the current or voltage channel expected to transfer need to be set, before connected to any source, set “DA coefficient 1 setting” to let “terminal 31, 32”(see MMPR-220 motor protective controller terminal figure for detail) output 4mA DC current; set “DA coefficient 2 setting” to let “terminal 31, 32” output 20mA DC current. After setting “DCS parameter settings”, when applying analog signal to corresponding channel, “terminal 31, 32” will output 4-20mA, especially when applying analog signal of value 0 it will output 4mA, when applying rated voltage or CT rated current, it will output 20mA. 5.2 Protective setting 5.2.1 Method of modifying protective setting  Move the cursor to “setting”, press “Enter” button, enter password(“0000” by default) to enter setting modification menu;  The method of modifying is the same as that of “parameter”;  Please refer to this manual “2.2 protective function” for protective settings.  The setting range and setting step in the item are set according to limit state.
