EVM430-F6779: EVM430-F6779

Part Number: EVM430-F6779
Other Parts Discussed in Thread: MSP-FET

Hi. I'm Korean, not good at english..

This question uses a Google Translator.

Please understand if it is strange.

I purchased the EVM430-F6779. Power is not supplied. 

I connected to VA, VB, and VN using a three-stranded AC cord, and the contents were initially displayed on the LCD, but suddenly the breaker went down and nothing was displayed on the LCD.

The breaker keeps going down when power is supplied after raising the breaker. 

What should I do?

    Hi Park,

    Thank you for the effort of translating your question and including the part number. I have a few follow-up questions.

    When you say "power is not supplied", do you mean that you are using the on-board power supply on the EVM? I will assume that you are since this is common.

    Can you include a diagram of the three-stranded AC cord? Normally, AC cords are single-phase with a 1) Line wire, 2) Neutral wire, and 3) Ground wire. Assuming that you are using single phase AC here, you want to connect 1) Line wire to VA and 2) Neutral wire to VN. Also, make sure that the jumpers are all connected according to Section 5.1.2 in the User's Guide. I would recommend referring to Figure 2 in the User's Guide as well. Even though it's for a 3-phase setup, you can just make the "Phase A" and "Neutral" connections for a single-phase setup.

    By "breaker", do you mean the circuit breaker for the AC circuit providing the voltage to the EVM? I will assume so, since the EVM does not have an on-board breaker. Please be very careful with connecting this EVM to High Voltage AC. There is no isolation (like some test equipment offers), so working with this High Voltage is very dangerous. DO NOT CONNECT YOUR MSP-FET TO THE EVM WITH HIGH VOLTAGE CONNECTED TO THE DEVICE! THE JTAG INTERFACE IS NOT ISOLATED LIKE THE RS-232/GUI PORT!

    Hopefully this helps, but please let me know if you have any more questions.

    Regards,

    Thank you.

    1. breaker

    This switch keeps going down when 220V is supplied.

    2. Connection status

    Thanks for the pictures. You will want to connect a load here as shown in Figure 2 in the User's Guide. I'm concerned that a short is occurring in your setup as it is now, which is causing the breaker to blow. Please make sure the voltage and current connections are correct.

    Regards,

    While slightly outdated and for different hardware, the Quick Start Guide to the Smart Meter Reference Design may provide some additional insight about how to connect a load to the EVM.
