10 STARTUP
The items below form a configuration and startup guide of the ECW500 and of the synchronous machine.
For a safe start-up of the application, it is really important to observe the instructions of this chapter.
Before, however, the ECW500 must have already been installed according to the chapter 5.
10.1 REQUIRED EQUIPMENT
Below are the items related to the required items to make the initial configuration of the ECW500.
■ Oscilloscope with current and voltage probes up to 1000 V.
■ ECW500 with HMI.
■
PC with Windows operating system and Superdrive G2 monitoring software or another software application
for MODBUS RTU protocol. For further information about the Superdrive G2 software, refer to the specific
manual.
■ RS485 converter to USB for access to the ECW protocol via PC.
■ A power supply for the electronics.
10.2 PREPARATION AND POWER-UP OF THE ELECTRONICS
Before energizing the power supply of the ECW500 (P-A/P-B/P-C), it is advisable to perform the following steps.
1. Check if the power, grounding and control connections are correct and firm.
2. Remove all materials left from the inside of the application panel.
3. Check if the synchronous machine current and voltage match the regulator.
4. Measure the line voltage and check that it is within the permitted range for the ECW500.
5. Energize the electronics (L~/N~ or BAT+/BAT-) and confirm the success of the power-up: the display
must show the standard monitoring screen (Figure 6.1).
