Commissioning and Start-up

Once the connection and installation procedure provided in the section Pre-requisites is performed and verified, the system can be started. To start the system, perform the following steps:

1. Turn the manual bypass switches I1, I2, I3 to OFF position.

2. Insert the corresponding key into the Lock Key of manual bypass cabinet and turn it clockwise. The key is locked in this position.

3. Energize the system by powering through the manual bypass input as shown in the following image.

   

4. Check the correct sequence of the phases and correct voltages between Phase-Phase and Ground-Neutral in input connections of the manual bypass cabinet with a multimeter and phasemeter.

5. Turn the manual bypass switch I2 to ON position.

   

6. Check the correct sequence of the phases and correct voltages between Phase-Phase and Ground-Neutral in OUTPUT connections of the manual bypass cabinet with a multimeter and phasemeter.

7. Turn the input manual bypass switch I1 to ON position.

   

8. Check the correct sequence of the phases and correct voltages between DVR OUTPUT connections and OUTPUT connections of the manual bypass cabinet with a multimeter and phasemeter to check connections between manual bypass cabinet and PowerLogic™ DVR units are correct.

   

9. Turn the output manual bypass switch I3 to ON position and then manual bypass switch I2 to OFF position.

   

10. Reassemble protection covers.

11. Set the internal switch I1 of PowerLogic™ DVR unit to ENABLE START position to enable to start the system.

    

12. Make sure that the PowerLogic™ DVR system is turned on and is in the Static Bypass mode. Check if there are no alarms. On the control panel of the screen, it should be in OFF mode.

    

13. Close the door of all cabinets.

14. Adjust the following settings in the Parameters menu.

    • Location

    • Time zone

    • Select language

    • Nominal AC voltage

    • Nominal frequency

    For more information to know how to edit the settings, refer Parameters Menu.

15. Turn the Lock Key anticlockwise and remove it from its lock. Insert the corresponding key into Start Key I4 of manual bypass cabinet, and turn the key clockwise. This causes a series of internal actions as described below, during the state transition from Static Bypass to Normal mode.

    • Activation of the pre-charging system

    • Close the main contactor to power the rectifier module

    • Supplies the inverter

    • Commands to open the static bypass

    • System begins to compensate for disturbances caused by its input

16. Check that the system values are correct and there are no alarms. Check that the system is in the Normal mode.

    

Once the above steps are performed correctly, the PowerLogic™ DVR system can be operated.
