Quick Manual / Practical(I)
Set parameters of EZA via RS-485.
①
Check that the specified voltage is applied to the grid side and the battery side,
and if discharging, check that the load such as the inverter is connected.
②
If charging, short pin 9 of CN to the SG potential (eg pin 8). To discharge, leave pin
9 open. This can be switched even while the EZA is running.
EZA starts up when pin 7 of CN is shorted with SG potential (for example, pin 8).
The fan rotates and the main converter starts and starts power conversion.
When pin 7 is opened, EZA stops and enters waiting (standby).
⑦
Stop.
⑥
Confirm startup.
⑤
Startup.
④
Select either charge or discharge.
③
Set parameters of EZA.
Refer to the communication manual for how to set parameters.
Refer to the Quick Manual Practical II for the parameter setting method using
the GUI software CNVCommCC.
When EZA start up, the green LED on the front panel lights up or
flashes. And CN pin 3 is shorted to SG potential.
When pin 7 is opened, the main circuit of EZA stops immediately, but the
fan continues to rotate for about 3 minutes for cooling and then stops.
It is possible to overwrite (change) the parameters of EZA after startup.
After the end of reception from EZA, please start transmission with an
interval of 2ms or more for RS485. Also, for communication using a
broadcast address, make sure that the issuance command interval is
200ms or more. Note that EZA does not reply to commands using a
broadcast address.
