DETAILED DESCRIPTION

RSGT….

A 3-phase controlled soft starter for centrifugal pumps and ventilators that controls all the tree phases to achieve current balancing on all the phases for minimized vibrations during motor starts and stops.
The dedicated self-learning algorithm that have the RSGT manages to achieve a very smooth starting and stopping performance with minimal settings resulting in a very easy to use solution.
The new RSGT series have cmpact housing in small dimensions 45 mm : 12, 16, 25Α, 75 mm : 32, 45, 55 Α and  120 mm : 70, 90 Α) thus facilitating replacement of contactors and start-delta starters.
The RSGT includes an overload protection (class 10) and soft-starting and soft-stopping times can be set independently for a finer control. In this case there are 3 knobs to adjust: start time, stop time and full load current (FLC) setting for the overload protection. Also, there are many diagnostic functions including phase sequence, locked rotor protection and also shorter SCR for improved protection in case of abnormal conditions.
Soft starter status indications are provided by means of three LEDs for supply, ramping and alarm indication. There are a 4th LED to select whether alarms follow an auto or manual recovery. In case of manual recovery of alarm, a push button is also available to reset the soft starter from alarm status.
Additionally, RSGT series is also equipped with two output relays for alarm (NC) and top of ramp (NO) indication. From RSGT..32 up to RSWT..90 are also equipped with a run relay.
