Page Device fault Power on Ready to start Output 2 – action [ There is one thyristor for the positive and one thyristor for the negative half-wave.

Remaining time for tripping Standard display off Menu: The soft starter is integrated into your system as a standard slave by means of the GSD file. Page – Soft starter with star-delta starter as When the control supply voltage returns, the trip condition of the thermal motor model before voltage failure will be restored.

Page 37 ms of activation of the start command for the 3RW Subsequent older diagnosis messages are not deleted. Note The “Coasting down” This internal thyristor protection function is not sufficient, however, in the event of a defect in the motor windings or a short-circuit in the motor’s power supply cable, for example.

In order to protect plants, systems, machines and networks against cyber threats, it 3wr44 necessary to implement — and continuously maintain — a holistic, state-of-the-art industrial security concept. For optimum motor protection, use a combination of electronic motor overload protection and evaluation of a temperature sensor integrated into the motor. Page Restoring the factory settings All settings made or saved so far will be discarded and the device will be reset to the basic factory settings master reset.

The motor stop can be set optimally according to application and deployment.

Problems That Can Occur Commissioning 6. Connecting the generator directly in 3rw4 supersynchronous range may cause soft starter mahual. Notice Log lists cannot be deleted while the motor is running. Status display select Settings select Parameter set 1 select Motor 1 select Starting settings select Stopping settings select Stopping mode Coasting down change Figure Emergency start active Alarm bit is deleted when emergency start is deactivated.


Page – Data set – Technology parameters 4: Standstill detection does not take place in the soft starter and, if required, must be realized by means of external measures.


Application And Use Phase angle control and schematic diagram of a soft starter with internal bypass contacts Application and use Applications and selection criteria 3RW44 soft starters can be used as an alternative to star-delta wye-delta starters and frequency converters. Three to four times the value of the motor’s rated operational current I can be assumed as typical here.

These utilization classes are highlighted in the Technical Data by an orange background. Page L2 is missing. Page – Starting Mode: Invalid parameter value Alarm bit is always deleted when acknowledged with “Trip Reset” or valid parameters have been received.

Both the measured maximum and minimum phase currents in bypass operation are stored per phase. Got it, continue to print.
