EZA2500W series
Quick Manual / Practical (II)
Apply the specified voltage on the grid side and battery side terminals of EZA.
Start the personal computer on which CNVCommCC is installed, and confirm that
it can communicate with EZA according to the operating instructions distributed with
CNVCommCC.
Set parameters via RS485 while referring to
2) Operation of Manual CV mode,
②
Set parameters of EZA on pages 6 and 7 of this manual.
①
Short the pin 7 (RUN) of the external signal connector CN to SG (signal ground,
e.g. pin 8).
②
EZA starts the main circuit from the Waiting and starts discharging.
③
To switch to charging, short pin 9 of the external signal connector CN to SG.
④
If pin 9 is opened, discharging will start again.
⑤
When pin 7 is opened, EZA stops the main circuit and enters Waiting.
⑤
Start EZA.
④
Check that communication is possible with RS-485.
⑤
Set parameters of EZA.
③
Restart the control board.
The control board reads the values of DIP switch
and rotary switch at restart.
The control board is also restarted by applying the
specified voltage to either the battery or grid side.
Even when using an external CN, parameter settings must be made via RS-
485.
After setting the parameters, the RS-485 cable can be removed.
