16. RESET:
The error condition can be reset through the reset button at the front of the SSW-05 Plus, or through a momentary
contact closure (0.5 seconds) at DI2 (digital input for reset). Other alternative to reset the SSW-05 Plus is by
switching On/Off the power control supply of the electronics (A1 and A2).
Note:
The SSW-05 Plus also provides the automatic reset by enabling this function through the dip-switch (auto):
1) The automatic reset occurs after 15 minutes in the following fault conditions:
- Overcurrent, Phase Loss, Locked Rotor, Immediate overcurrent of the SSW-05 Plus by-pass relay, Overcurrent
before By-pass, Frequency out of tolerance, Contact of the internal By-pass relay is open and power control
supply undervoltage.
2) For incorrect phase sequence there is no automatic reset.
3) For motor overload and thyristor overload there is a specific algorithm for the automatic reset time.
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.
Possibles Causes
Phase fault in the three-phase
network
Short-circuit or thyristor fault
Motor is not connected
Motor connection is not correct
“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.
The wiring at DI1 is open (not
connected).
Keypad cable misconnected.
Electrical noise in the
installation (electromagnetic
interference).
