Brief Introduction

The solid state soft starter uses yellow LEDs to indicate that a fault has occurred and shows the corresponding fault information on the LCD display. There are 19 kinds of protection functions. When the protection function of series solid state soft starter is activated, it stops immediately and the LCD display shows the current fault. Users can analyze the fault according to the fault content.

Fault	Cause of fault	Solutions
Main power supply phase loss	Lack of phase sequence at startup or during operation	Check whether the three-phase power supply is reliable phase?
Phase sequence error	Phase sequence reversed	1. Adjust the phase sequence of the three-phase main power supply. 2. Set B09 parameter to not detect phase sequence.
Parameter loss	Setting parameters missing?	Check each function item setting and reset
Overload protection	After a certain time, the current is still too high, resulting in motor overload.	1. Check and correct the cause of overload and check if the current limit multiplier is set too low. Check whether the starting time is set too long. 3,Check whether the motor overload protection level is set reasonably. 4. Check whether the motor rated current is set correctly.
Running overcurrent	Load suddenly increased? Load fluctuates too much?	1. Adjust the load running condition 2. Check whether the B03 parameter item is set too small.
Underload protection	Motor running current lower than rated current	1. Check the cause of underload and make corrections 2. Check whether the setting is according to the operating conditions.
Phase current imbalance	Three-phase current imbalance	1. Check if the three-phase current imbalance exceeds the imbalance protection level set in parameter item B01. 2. Adjust the load operating conditions.
