Chapter III: Digital Trigger Controller


1. Overview                                                                            

With the core of TMS2000 32-bit digital signal processor (DSP), XAZK-ST6M/12M intelligent full-digital trigger controller, characterized by  powerful calculation function, high integration and strong antijamming capability, can achieve full-digital intelligent regulation control, digital trigger and remote control functions. All control parameters are digital without temperature drift change. With SMT technology, double-layer embedded structure, small size, flexible and convenient installation and wiring, the controller integrates the power supply, synchronous and digital PID, digital trigger, pulse transformer and site industrial bus communication module.

With rich network interfaces, the controller can be directly connected with various mainstream buses on site and very suitable for the modern industrial site. General interfaces are strongly compatible and interchangeable with the control panels of other manufacturers.

4. XAZK-ST6M/12M Digital trigger controller debugging 


   Digital panel: The digital trigger controller is directly equipped with a Chinese digital operation panel with a buzzer. When touch-button is pressed effectively, the buzzer issues the indication sound "DI". As shown below, each parameter name is attached with an indicator light. The corresponding indicator light is on when a parameter is set; the indicator light after overcurrent is on when the overcurrent value is set. LED digital tube window displays the current parameter value. Press [↑] and [↓] to increase or decrease the parameter value and then press [ENT] to save the modified data. Press [←] and [→] to select the parameter to be set.

Note: A password set item on the panel can only display the feedback and set the set value when a wrong password is entered, and can set all parameters when the correct password is entered. The password is 0.

4.1. Connect dummy load: connect a section of electric stove wire to make the DC current at 10~20A when outputting the rated DC voltage. Set STM12 open loop working mode.

4.2. Preliminary pulse inspection: raise the given value and STM12 generates pulse after delivery of current to the controller. Check whether the pulse is to the element.

4.3. Choose the pulse clock count: the pulse clock count selection function of the handheld terminal can change the pulse clock count. Select the appropriate pulse clock count to make STM12 pulse adapt to the main circuit and achieve the given value from 0 to maximum and main circuit output voltage from 0 to maximum smoothly without out of control.

4.4. The user with pulse adaptive main circuit function can enable this function, so that STM12 pulse automatically adapts to the main circuit without manual setting. This function can only be used at small dummy load debugging.

4.5. Adjust the voltage feedback amplitude: guarantee the linear change of the feedback voltage with the main circuit voltage, 5V≤UF, amplitude ≤10V

4.6. Set the voltage rate: set the voltage rate to 1.00, then view the voltage feedback displayed value V and record the actual value V'' of the voltage. Voltage rate calculation formula: voltage rate = V'' (actual value) ÷V (voltage feedback displayed value), such as actual voltage value V'' = 17.0V, and current feedback displayed value V=340, and then the voltage rate = V'' (actual value) ÷V (voltage feedback displayed value) = 17.0÷340=0.05. Set the voltage rate: set the voltage rate to 0.05.

4.7. Adjust the following parameters through the digital panel: ① overvoltage value, ② voltage limiting value, ③ minimum control angle α.

4.8. True load debugging: connect the true load to make the output current at about 10%~50% of the rated current and ensure normal current/voltage feedback collected by the digital controller.

4.9. Set the current rate: set the voltage rate to 1.00, then view the current feedback displayed value I and record the actual current I''. Current rate calculation formula: rate = I'' (actual value) ÷I (current feedback displayed value), such as actual current value I'' = 1200A, current feedback displayed value I=120 and current rate = I'' ÷I=1200÷120=10.0, then set the current rate to 10 times.

4.10. Through the digital panel manual, adjust: 1. Overcurrent value, 2. current limiting value, 3. soft start time, 4. soft stop time.

4.11. Select PID regulator: after manual setting of the basic parameters such as P and I, the system will start PID parameter self-tuning function and the controller automatically obtains the optimal parameter adapting to the load if the basic parameters cannot meet the system operation requirements. The basic parameters can be reset according to the self-tuned value of PI parameters.

5. Precautions

u Take down the digital controller when using the thyristor unit for insulation test; otherwise, the digital controller will be damaged permanently.

u Select the shielded twisted pairs as the communication line and trigger pulse line and note the wiring polarity without inverse connection.

u The company is not responsible for the damage to the components other than the digital controller during use. The machine shall not be removed and the warranty label and user parameter label shall not be damaged during warranty.

u To prevent closing impact of the main circuit, the control panel shall be powered on before the main circuit. The controller start end is closed during or after power on of the main circuit.

6. Appendix: an operating manual

7. Service commitment: free repair within one year under normal use and operation by the user except lightning stroke and power supply shooting and free technical consultation. 

Precautions

1. Use the lifting button if the human-machine interface cannot be operated. Press and then release the up button for inching up operation; press on the up button for more than 0.6s for continuous rise until the maximum given limit value or button loose; press and then release the down button for inching down operation; press on the down button for more than 0.6s for continuous fall until zero or button loose.

2. In case of channel failure but normal output current without other exception, record the failure information alarmed historically and conduct a reset operation to possibly return the channel to normal; if not, notify the maintenance personnel and contact the manufacturer, but the equipment can be used as usual without affecting the production.

3. Record the control angle, ammeter displayed value, human-machine interface displayed current, failure information, AC current of each phase at the rectifier transformer network side, on-load voltage regulation gear failure indication and other parameters and operate according to the operation rules of the manufacturer, such as recovery to original current or shutdown for orders.

4. The equipment starts feedback failure protection and is switched to the manual status if the DC output current suddenly falls to zero due to sudden power outage of the rectifier transformer. In case of normal feedback, the equipment is manually switched to automatic mode.

5. Adjust the current with the given button if the equipment can continue to operate normally but the human-machine interface cannot display or operate normally in case of hot standby failure.

6.4.7 Do not beat or operate the digital panel with hard matter and keep the screen clean.
