ABB PSTX30 Installation And Commissioning Manual page 107

Faults can be set to an Event group by a parameter
option called Out. The Event group can be configured for
relay output to control other devices in an application.
As default all parameters are set to one Eventgroup.
At occurrence, the following action is decided based on
user preference:
• Stop motor and manually reset is required
• Stop motor and automatic reset is performed
• Only indication will be given ( fire pump mode only)
• Auto-restart possibilities
In addition to the basic actions, depending on the fault,
further actions can be added or the basic actions can be
modified. If several faults occur they are all stored in a
sequence and an individual reset for each fault must be
done if manual reset is selected.
Fire pump – Faults disabled:
The normal operation of the softstarter when a fault is
detected is to do a direct stop.
If the the Fire pump is enabled and a fault is detected,
the softstarter will try to run the motor according to the
start and stop signals, ignore safety, and continue to run
regardless of consequences.
The softstarter can manage to run the motor depending
on what fault is detected.

The softstarter has been shorted and can not stop the
power down to the motor when it is connected in-line, the

a line contactor or a circuit breaker, the user can break off
the motor.
