Product Description
Ordering Code RSWT 40 16 E 0 V 1 0
RSWT is a 3-phase controlled soft starter for centrifugal pumps. RSWT controls all the three phases to achieve current balancing on all the phases so as to minimise vibrations during starting and stopping of centrifugal pumps.
Through a dedicated self- learning algorithm, the RSWT manages to
achieve a very smooth starting and stopping performance of centrifugal pumps with minimal settings resulting in a very easy to use solution. The RSWT up to 25A (11kW @
400V) comes in a compact
45mm housing thus facilitating replacement of contactors and star/delta starters.
The RSWT...V00/V01. version requires just 1 knob setting for the soft-starting/soft-stopping time of the pump. No further adjustments are required in this case.
The RSWT...V10/V11. version includes an overload protection (Class 10) and soft- starting and soft-stopping times can be set independently for a finer pump control. In this case there are 3
Note:
knobs to adjust: start time, stop time and full load current (FLC) setting for the overload protection.
RSWT is equipped with a number of diagnostic functions including phase sequence, over- and under- voltage monitoring, locked rotor protection and also shorted SCR for improved pump protection in case of abnormal conditions.
Soft starter status indication is provided by means of three LEDs (green, yellow, red) for supply, ramping, and alarm indication. Additionally, RSWT (45mm) is also equipped with two output relays for alarm (Normally closed - NC) and top of ramp (Normally Open - NO) indication. In case of the RSWT…V10/ V11. series, there is a 4th LED to select whether alarms follow an auto- or manual recovery. In case of manual recovery of alarms, a push button is also available to reset the soft starter from alarm status.
RSWT...32 up to RSWT...55 are also equipped with a run relay.
