8.3.7 Displayed Current calibration 8.3.7 Displayed Current calibration
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. The
way of calibration is that: the parameter of Starting mode is set Jogging
, 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 is saved automatic.

User parameter is not right. When power is on, the self-test is carried
out. It is shows on the keyboard if the parameter is not right. In such
circumstances, the factory default value will restore automatically
Solution: Because the factory default value is restored, so user
should set the parameter again.

Fault Fault Explanation and Solutions Explanation and Solutions
Phase lack. The system detects this fault on any time. If this fault is
detected, the protection will act within 120 ms, and the fault code
display on the keyboard.
Solution: Check the power supply.

otor current is higher than the current limit. In start sequence, if the
high current which is six times as the rate current is detected( such as
stall), the trigger sign of the thyristors is locked within several s.
The fault code display on the keyboard and system enter fault protect
state.
Solution: Check load or mechanical drive part.

Solution: Check load or mechanical drive part.
Over Temperature. The sink temperature of the thyristor is detected
consequently on any time. If the temperature is over what is set,
protect will act within 3 S. The fault code displays on the keyboard.
Solution: Check whether the load is too heavy or the frequent of
starting is too much.
Over Temperature. The sink temperature of the thyristor is detected

Solution: Check whether the load is too heavy or the frequent of
starting is too much.
Starting time is over limit. In voltage ramp mode , the actual starting
time is longer 3 seconds then Starting Time use set , the actual cur-
rent is not lower than the 125% of the rate current in percent. In Cur-
rent Limit mode , the actual starting time is longer then Starting
Time use set , the actual current is not lower than the 125% of the
rate current in percent. System enter fault protect state. The fault
code displays on the keyboard.
Solution: Check whether the load is too heavy or the starting time is
too short.

too short.
1. The inquiry method of last fault code shows at the chapter 8.2.2 the last
fault
2. In fault state, user can reset the fault as following:
Press key and maintain 3 seconds.
Connect controlled terminals RET and COM, and maintain 3 seconds.
Shut down the power and power on again.
