7.17 Faults
The softstarter is equipped with a number of fault
detection functions to protect the softstarter.
Faults detection is always running as default and cannot
be turned of by the user. If a signal is malfunctioning in the
softstarter, the motor or in the power network level, a fault
will occur. Supervised faults can be divided in internal and
external faults.
Internal fault:
There has been a fault in equipment connected to the
softstarter, see chapter 10 Troubleshooting, and contact
ABB sales office if necessary.
External fault:
There has been a fault in the softstarter, see chapter
10 Troubleshooting, and contact ABB sales office if
necessary.
When a fault occur, the type of fault will be described on
the home screen, the red Fault LED light will illuminate,
and the powersupply to the motor which is connected to
the softstarter will be turned of (Direct stop).
When any of the faults are detected these basic actions
will be performed:
7
- Fault LED will light up
- The type of event is displayed
- The type of event is logged on the event list
Faults cannot be configured in other way then to set the
reset mode to stop-automatic or stop-manual.
Faults can be set to have automatic reset or manual
reset. For every fault, there is parameter options called
Operation, which can be set as:
• Stop-Automatic – The engine stops and resets
automatically after the fault condition has been
corrected*.
• Stop-Manual – The engine stops and has to be reset
manually after the fault condition has been corrected*.
* Faults cannot be reset before the fault condition is
corrected.
Example: If stop-manual is set at EOL Fault (engine is too
warm) the softstarter can only be reset once the engine has
cooled down to the right temperature.
When the engine has reached below a certain temperature, the
fault condition will be gone, and then reset. The fault will be
cleared from the fault list and the engine can be started again.
