Possibles
Causes
Phase fault in the three-phase
network
Short-circuit or thyristor fault
Motor is not connected
Motor connection is not correct
Driving problems with the input
contactor.
Input fuses are blown.
Incorrect programming of the
Motor Current Trimpot or P105.
Motor current consumption
lower than required for
actuation of the phase loss
protection.
“Motor Current” trimpot or
P105 (motor current) has
been set incorrectly. The set
value is too low for the motor
being used.
Load on the motor shaft too
high.
Too much successive motor
starts.

protection saved when

Attention - Very Important
Both digital input (DI2) and reset button of the SSW-05 Plus should be used only for the
reset after a fault condition.
If the reset function is used when the SSW-05 Plus is operating at rated voltage, the
internal by-pass relays will open their contacts under load, thus jeopardizing their life.
17. FAULTS AND POSSIBLE CAUSES:
When a fault is detected, the Soft-Starter is disabled and the Fault Code is displayed by flashing
LED´s or on the readout display in the EXX form, where XX is the actual Fault Code.
To restart the Soft-Starter after a fault has occurred, the Soft-Starter must be reset. In general, the
reset can be made as follows:
disconnecting and reapplying the AC power (power-on reset);
by pressing the key “RESET” on the SSW05-RS front panel (reset key);
through the HMI-SSW05-RS by pressing the key (manual reset);
automatic reset by enabling the function through the dip-switch (auto) or though P106 and P220.
via digital input: DI2.
Table below explains how to reset the fault and show the possible causes for each Fault Code.
