Reset - WEG SSW-05 Manual Del Usuario

Installation and Operation Manual - SSW-05 Plus
3) The reset of the electronic overload protection can be set to manual function (man). In this case
the reset must be made via digital input 2 (DI2) or by means of the reset button. If the reset
setting has been set to automatic (auto), the error condition will be reset automatically after the
cooling of the equipment;
4) When the electronic overload protection is disabled via dip-switch, the thermal image is reset.
Notes
1)The thermal thyristor image is not saved in the internal Soft-Starter memory. When the
SSW-05 is enabled/reinitialized, the value of the thermal thyristor image assumes zero;
2)When the motor is running in full voltage, the cooling of the thyristor overload Thermal
Image happens. This is because of the By-pass of the thyristors.

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).
Notes
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, power control supply undervoltage and External Fault.
2)The automatic reset time may be changed at P206. For more details refer to Detailed
Parameter Description.
3)For incorrect phase sequence there is no automatic reset.
4)For motor overload and thyristor overload there is a specific algorithm for the automatic
reset time.
