Why Choose Us

Winston soft starter connection of the main circuit and the grounding terminal

(I) Main circuit power input terminal (R,S, T) 

a.Connect the main circuit input terminals R, S, T to the three-phase AC power through the circuit breaker for circuit protection or circuit breaker with leakage protection without considering the connection sequence

b.Do not use ON/OFF of the main circuit power to control running and stop of the soft starter, instead, such should be controlled by means of the control terminal or RUN and STOP buttons in the keyboard panel of the soft starter upon power on. 

c.Do not connect the soft starter to the single-phase power. 

(2) Output terminals of the soft starter (U ,V ,W ) 

a.Output terminals of the soft starter should be connected to the three-phase motor in correct phase sequence. If the rotation direction of the motor is incorrect, switch connection of any two phases among U, V and W.

b.The output end of the soft starter shall not be connected to capacitor or surge absorber. 

c.If the wire between the soft starter and the motor is very long, the distributed capacitance between the wires will generate high­frequency current which may cause over-current tripping, leakage current increasing and poor current display precision of the soft starter. Therefore, it is suggested that the motor connection wire should be no more than 50m.

(3) Grounding terminal of the soft starter (〨 G)

a.For safety and noise reducing, the grounding terminal G of the soft starter must be well-grounded. To prevent electric shock and fire accidents, the metal enclosure and frame of the electric equipment should comply with the requirements of the national electronic procedures.

MODBUS Communication Protocol

Modbus is a kind of serial asynchronous communication protocol with RS485 as the physical interface. Being designed for Modicon PLC, it has the structural features of PLC. In network control, it can read and write the PRS 3000 as if it were a PLC. It can project the start and stop control, status information (current, fault etc.) and function parameters to the holding register (4:XXX). Its read and write control shall be conducted through the PL master station. When connected to other Modbus equipment, connection should be conducted as per the diagram below:

Description Of Protection Functions

WSTR 3000 series soft starter possesses complete protection functions to protect the operation security of the soft starter and the motor. During operation, the protection level and protection parameters should be properly set base don different circumstances. 

● Over-heating protection of the soft starter: the protection will start when the temperature rises to 80℃±5℃, and it will stop when the temperature falls to 55℃(lowest). 

● Delayed time of input phase loss protection: <3s. 

● Delayed time of output phase loss protection: <3s.

● Delayed time of input three-phase unbalance protection: <3s. Taking the deviation of current in each phase is over 50%10% as the criteria, when the load current is less than 30% of the nominal rated value of the soft starter, it is confirmed that the deviation will increase. 

● Protection time of over-current during starting: the protection time shall be continued to be longer than 5 times of the maximum operating current of code F5, 

● Delayed time for power under-voltage protection: when the power voltage is under the extreme value 40%, the protection time< 0.5s, when the power voltage is below the set value, the protection time< 3s. 

● Delayed time for power over voltage protection: when the power voltage is over the extreme value 130%, the protection time< 0.5s, when the power voltage is over the set value, the protection time< 3s. 

● Delayed time for load short circuit protection < 0.1 s, if the current is more than IO times of the nominal rated value of the soft starter, this protection shall not replace the fuse or short circuit protection device. 

The above time parameters are the periods from the valid signal being detected to the tripping protection directive being given; these parameters are for information only. In the event that the protection functions of the soft starter fails to meet the requirements of customers, special protection devices should be installed to ensure the safety.
