If the power off the motor is smaller than that of the soft starter, this para-
meter must be calibrated to ensure the motor can gain the better starting
effect and protect function.
The way of calibration is that: Before power on, connect terminal RET and
COM, then power on, the shows in the keyboard. Press the key within
5 seconds, and keep press this key until the rate current displays in the
keyboard. Press the key or to modify this parameter. Press the key
and keep 5 seconds to save and return ready state. Then the rate
current is the value user set. Remove the line connect the terminal RET and
COM at last.

11 Displayed Current Calibrate11 Displayed Current Calibrate
The displayed current of each Soft starter is calibrated before leave factory.
If user finds the current value showing on the keyboard is not equal to the
actual current value, this parameter must be calibrated.
WAY1:Setting the starting mode to Jogging, and the motor must be
connected to its load, the parameter of Jogging Voltage is set
below 40%, keep press key ( enter the Jogging state ), press
and or key at the same time to modify this value
until it is equal to The actual current. Then release the key and
Key, the modified parameter save automatic.
The other way can be adopted sometimes.
WAY2: At the B state, press + key or + key, this
parameter can be modified to match to the actual current.

12 Fault Protection and Display12 Fault Protection and Display
There are 11 protections. When the fault is detected, soft starter stop
immediately, the fault code displays on the keyboard. User can find the
solution by check the explaination to this fault code. After the fault is
solved, pres the key(keep 3 seconds) or connect terminal RET and
COM to reset and return ready state.
