Product Introduction

Soft starter is a motor control device that integrates soft start, soft stop, light load energy saving and multiple protection functions It mainly consists of three-phase anti parallel thyristors connected in series between the power supply and the controlled motor and its electronic control circuit Different methods are used to control the conduction angle of three-phase anti parallel thyristors, so that the input voltage of the controlled motor changes according to different requirements.

Features

1.Adopts the Microprocessor digital auto control, it has great electromagnetic performance. soft starting, soft stopping or free stopping.

2.The starting voltage, current, soft-start and soft-stop time can be adopted according to different loads for reducing the shock of starting current. stable performance, easy operation, direct display, small volume, digital set, has tele-control and external control functions.

3.Have protection against phase-loss, overvoltage, overload, overcurrent, overheating.

4.Have functions of input voltage display, operating current display, failure self-inspection, fault memory. has 0-20mA simulation value output, can realize motor current monitoring.

AC induction-motor has advantages of low-cost,high reliablity and infrequent maintainance.

Disadvantages:

1.starting current is 5-7 times higher than rated current.And it requires that power prid has large margin,and it also would reduce the working life of electrical control device,improving maintainance cost.

2.starting torque is doule-time of normal starting torque to cause the load shock and drive components damage. The RDJR6 soft-starter adopts the controllable thyistor module and phase shift technology to improve the voltage of motor regularly.And it can realize the requirement of motor torque,current and load by control parameter. RDJR6 series soft-starter adopts microprocessor to control and realize functions of soft-starting and soft-stopping of AC asynchronous motor,has complete protection function,and widely used in Motor drive equipment in the fields of metallurgy,petroleum,mine,chemical industry.

Button instruction instruction
RDJR6 series soft-starter has 5 kinds operational state: ready, operation, failure, start and stop,ready, operation, failure
has relative indicator signal. Instruction see above Table.

In the soft-starting and soft-stopping proceessing, it can not set data, only if it is under other state.
Under setting state, setting state would quit the setting state without any operating after 2mins.
First press on “enter” button, then charged andstarting starter. After listening the alert sound, then it can reset the
data back factory value.
