    Overview This manual is applicable to QDS1 series products. This manual is intended to guide qualified personnel in the installation and operation of this product. In the case of a registered trademark and business ownership, final interpretation right to this manual is belonged to Jiaxing Dannahe Electronic Science&Technology Co.,Ltd.
  • Page 5: Function And Feature

    1.Function and Feature QDS1 series LED AC motor soft starter is new type starting equipment with advanced international level. This equipment designed and manufactured by the technique of power electronics microprocessor and modern control theory. This equipment can limit the start current efficiently when the asynchronous motor starts.
  • Page 6: Product Type And Inspection

    2.Product Type and Inspection Each QDS1 series soft starter is tested. Only the starter that passes the function and running test can leave the factory. After receiving the equipment, the user should inspect it according the steps described below. Please notify the supplier immediately if you find any problem. Check the nameplate:Check the item(s) nameplate catalog number against the purchase order.
  • Page 7: Environment And Installation

    3.Environment and Installation 3.1 Environment The environment is important to the equipment life. So please install the soft starter on the site described below  Operation Condition for the standard products Power Supply: Urban power, self-provided substation, diesel generating sets Three-phase AC: 380V (-10%, +15%), 50Hz.

     Cabinet installation If the product is installed in the cabinet, make sure there are good ventilation in the cabinet. The products can be installed vertically or horizontally. Horizontal layout shows in Figure 3-2. Vertical layout shows in Figure 3-3. User can adopt any of them. Note: If the vertical layout is adopted (especial in fan air cooling mode), clapboard should be installed between them to avoid that the upper starter is affected by heat generated by the lower starter.

  • Page 11: Control Mode

    6.Control mode This product has three start modes: Voltage Ramp and Current Limit and jogging. These start modes is independent. Only one of them can be chosen. Text below introduce that the different of them and which mode should be selected. 6.1 Voltage Ramp The waveform of the voltage shows in Figure 6-1.
  • Page 12: Jogging

    6.3 Jogging At this start mode, the output voltage reaches the initial voltage U1 quickly, and remains unchanged. Changing the U1, the output voltage and torque of the motor will change corresponding. (See figure 6-3). It is convenient to judge the director of the motor. Figure 6-3 6.4 Heavy load The waveform of the voltage shows in Figure 6-1.

  • Page 15: Special Parameter

    9.Special parameter  Rate Current The Rate Current indicate that the output current of the soft starter at the rate power. This parameter changes with the output power of the soft starter. For detail see chapter 9. User can query this parameter by the method shows below.
  • Page 16: Displayed Current Calibration

    10.Displayed Current Calibration The displayed current of each Soft starter is calibrated before leave factory. If user finds the current value showing on the keyboard is not equal to the actual current value, this parameter can be calibrated again. WAY1:Set the starting mode to Jogging, and the motor must be connected to its load, the parameter of Jogging Voltage is set below 40%, keep press RUN key (enter the Jogging state), press PRG and up or down key at the same time to modify this value until it is equal to the actual current.
  • Page 17: Parameter Details

    11.Parameter details Starting There are 4 starting mode. User can set this parameter by keyboard referring to Mode chapter 8-1 and chapter 9. Initial This parameter is valid at the Voltage Ramp mode. Voltage This parameter indicates that the initial output voltage of the product at the instant of starting and also indicates the initial voltage of the motor (see figure 6-1).The more this parameter is, the more the starting torque is.
  • Page 18 This parameter is set for the protect function aimed at that the difference of 3 phases Current current is bigger at running. The default value is 30%.The smaller this parameter is, unbalance the more the sensitivity is. This parameter should not be too small, in order to avoid factor the protection is too sensitive to influence the normal operation of the equipment.
  • Page 19: Working State

    12.Working State  Ready When the soft starter is power on, self-inspection is performed. The self-inspection includes: test the parameters that the user changed (fault protection of parameters setting), check if the phase of voltage is not right (protection of missing supply phase) and check if the system temperature is too high (protection of overheating) etc.
  • Page 20: Fault

    13.Fault There are 11 protections. When the fault is detected, soft starter stop immediately, the fault information displays on the keyboard. User can find the solution by check the explanations to this fault information. After the fault is solved, pres the STOP key(keep 3 seconds) or connect terminal RET and COM to reset and return ready state。For detail see table 13-1 ...
  • Page 21 Overload  Overload protection function is in used during the process of starting and running There are 8 protection levels. The default is 4(same as 15 in IEC60974-4-2 standard). User can set this parameter according to de load situation, the smaller this parameter is, and the shorter the starting time of protection is, vice verse.
  • Page 22: Test Running

    14. Test running 14.1 Inspection before running For safe running, user should inspection the items show as following items before power on. Is the power of the soft starter match to that of the motor? Does the insulation of the motor meet the requirement? Is the wiring of power and motor line right? Do all the nut screw tightly Measure the input power (R\S\T) using multimeter, Check whether there is short circuit.
