“SJR2-3000” series online micro-power consumption motor soft starter of Shanghai SANYU. The company has made further technical improvement in both the software and the structure of the soft starter according to the market demand. 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.
Wire connection of SJR2-3000 series Soft starter
Connection point output
01, 02 are AC220V power input to the control panel
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.
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
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)
Soft stop input
The motor will slow down for soft stop when 08 and 10 are disconnected (or automatically stop).
The motor will start for running when 09 and 10 are connected.
Common terminal for signal input of the connection points
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.
Input and output signal terminal of RS485 communication, can be used to connect several soft starters.
