Product Description

SJR2-3000 Series soft starter with inbuilt bypass contactor the soft starter provides complete motor protection functions including start control, running and overloading, phase failure, three-phase unbalance, over-voltage, under-voltage protection and so on with no need to further install bypass contactor and thermal relay, therefore, as another great achievement in the intelligentization of motor protection and networked technology application, it simplifies the circuit, reduces the volume, cuts the cost, makes installation and using more convenient.

Power supply: Three-phase AC 380V or 660V± 15%, 50 Hz or 60 Hz commercial power, private power station or diesel generator set, the power capacity must meet the soft starter's starting requirements on motor.
Applicable motor: Three phase squirrel-cage asynchronous motor, the rated power of the motor should match that of the soft starter.
Start frequency: No requirements, the specific frequency shall be depended on the loading.



 

Classification	Terminal marking	Terminal description	Function description
Connection point output	01, 02	Power input	01, 02 are AC220V power input to the control panel
	03, 04	Running output (delay)	03, 04 are programmable relay output, the delay time is set by the code F4 while the output function time is set by code FE.
	05, 06	Fault output	005, 06 are fault relay output, they will be on when there's fault with the soft starter or the power is cut off and be off when the power is on. (capacity of the connection point AC250V/3A)
Connection point input	07	Instantaneous stop input	The motor will stop immediately when 07 and 10 are disconnected (or be tandemly connected to the normally closed point of the thermal relay)
	08	Soft stop input	The motor will slow down for soft stop when 08 and 10 are disconnected (or automatically stop).
	09	Start input	The motor will start for running when 09 and 10 are connected.
	10	Common terminal	Common terminal for signal input of the connection points
Analog output	11, 12	Analog output	11 and 12 are 4~20Ma DC analog output which are used to monitor the current of the motor in real time. The maximum value 20mA indicates the current of the motor is four times of the nominal current of the soft starter.4~20Ma DC meter can be connected for observation. Maximum load resistance of this output is 300Ω.
Communication	DB	RS485communication input/output	Input and output signal terminal of RS485 communication, can be used to connect several soft starters.
