FAULT TRIPS AND ALARMS
In order to avoid dangerous situations, damages to the motor, damages to the soft-starter or other materials, the
protections of the SSW7000 may actuate so that certain physical limits will not be exceeded.
In this regard, a fault is a condition that requires immediate stop of the soft-starter so as to prevent possible losses.
When a fault occurs, the SSW7000 is automatically disabled, and it cannot be restarted until the cause of the fault
is removed.
When a fault “FXXX” is detected, the following occurs:
Disabling of the SCR firing.
Opening of the vacuum contactors (line and bypass).
Indication of the fault code and description on the display.
Indication of the present fault at P0020.
Indication of the occurrence in the status word – P0680.
Status LED transition to flashing red.
Opening of the relay programmed for “No Fault”.
It saves the following data in the control circuit EEPROM:
-
The code of the occurred fault (it shifts the nine previous faults).
-
The motor overload integrator status.
-
The status of the enabled time (P0043) and powered time (P0042) counters.
In order to be able to operate the SSW7000 again after a fault trip, reset in one of the following manners:
Pressing the HMI
key (manual reset).
Through the reset soft key.
Automatically through P0208 setting (auto-reset time).
Through a digital input: DIx = 10 (P0263 to P0268).
Removing the power supply and reapplying it again (power-on reset).
When an alarm is detected, the following occurs:
Indication of the alarm code and description on the display.
Indication of the present alarm at P0021.
Indication of the occurrence in the status word – P0680.
Status LED transition to yellow.
The SCR firing is not disabled, the contactors do not open and the SSW7000 remains in operation.
Alarms are automatically removed when the condition that caused them no longer exists.
NOTE!
Fault and alarm occurrences are described in the programming manual, chapter 2 - Faults and
Alarms.
