Connection and External terminal The FWI-SS Soft Starter has three types of connection, as following Main circuit connection: it contains the wiring of 3-phase source input, the output to motor, and the pass -by contactor connection. External terminal connection that is the wire comes from twelve external terminals which including control signal and analogue output signal.
- Page 9 4.2 The external terminal Please see the diagram 4.2 ● Terminal ① ② are by-pass output, are used to control the by-pass contactor. They are normal open contacts and are closed when finishing starting. The contact capacity is Ac250V/5A ●...
- Page 10 Terminal ⑾ ⑿ are DC 0-20mA analogue output ,they show the current value of motor when real-time working, 20mA is full-scale value and is four times than rated current of nominal power of soft starter, while, we can contact a 0-20mADC current meter to check.

For e example, if you forbid any unexpected stopping or starting whether starting is running or in maintenance, you can set the Numerical Value as"7"which means forbidding any starting or stopping operation.
- Page 21 6. Protection Functions and theirs explanation We make our soft starters have all kinds of protection functions to protect the soft starter and the motor using. Please choose the correct Protection class and parameters according to your usage conditions! Over-heat Protection：when the temperature inside soft starter is up to 80℃±...
- Page 22 ○ Power voltage failure protection: the delayed time is separately less than 0.5s or 3s when the power voltage is less than half of limited value or less than the set value. ○ Over-voltage protection: the delayed time is separately less than 0.5s or 3s when the power voltage is move than 130% if limited value or more than the set value.
- Page 23 ● Basic protection includes the protection functions of over-heat, short -current protection and input failure-phrase protection when starting, but no protection of internal connector instantaneous-shop. we can se he protection glade when the motor is no need to be stopped urgently, such as fire pump.

- Page 25 ● If the soft starter starts badly , you can check whether the starting mode you choose is fit for your motor . Please see the detailed explanation at 7.2: the starting mode and application ●...
- Page 26 Note ：When the motor starts successfully , the pass-by-lamp will be lighting , that means the pass-by contactor is running . At this time, if the contactor is not closed, the motor will stop running, so you can check whether the connection to the pass-by contactor is right.
- Page 27 Note： It is normal that When the load equipments are light, the starting time is less than the set time. This mode generally fits for the occasions where the Motor must be started smoothly This mode is often used in the conditions which requires strict limit to the current when starting.
- Page 28 Note：This mode will cause big-current shock to the motor, so if the Ramp voltage or Limit-current mode can be used, please had better not use the Torque control to start 7.2.4 Ramp Current to start (The F9 item is set as"4", this starting mode is in use) 7.2.5 Double closed loop (Both Ramp Voltage and Limit-current)to start (The F9...
- Page 29 Output voltage of starter will be reduced gradually so that the Running Speed of Motor can be cut down smoothly in case of the Mechanical Shock. The Output Ending Voltage is the same as the initial Voltage. Soft-stopping Mode can reduce or remove the Surge of the loading equipments such as the Water Pump.
