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

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).


Start input

The motor will start for running when 09 and 10 are connected.


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.



RS485communication input/output

Input and output signal terminal of RS485 communication, can be used to connect several soft starters.
