Soft starter relay protection trips

Just increase your starting time setting on relay by 2-3 seconds i. if it is set 10 sec increase to 12-13 sec and so it will prevent motor tripping due to high viscosity. However make sure any incremental changes in. Semi-conductor fuses (High speed fuses) are the only type of fuses that are fast enough to achieve a fully type 2 coordination when using a soft starter. A separate overload relay for the motor protection is always required in combination with this type of fuse. If replacing the semi-conductor. New industry Technology regarding to Bussmann fuse, ABB breakers, Amphenol connectors, HPS transformers, etc. Cause: External power supply not connected. EN 60947-4-2 is the harmonized standard for softstart-ers and it instal-lation of the machine.
