2.8: Troubleshooting Guidelines in case

any fault is at load side

Thermal overload relay provide protection from:

a) overload condition at Motor 
b) single phasing at load side
  a) overload condition at Motor: check the suitable Motor current rating and adjust the overload relay setting  
      dial as per the requirement.
  b) Single phasing at load side – Overload relay tripped as inbuilt feature to protect from single phase faults.  
       Check the single phasing condition at Motor side terminal TB2,TB3 to Motor.
For both conditions restart the Starter after proper reset time of approx. 4 min.
