Reset; Faults And Possibles Causes - WEG SSW 05 Plus Guia Del Usuario

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
automatic reset by enabling the function through the dip-switch (auto) or though P106 and P220.
