Charge/Discharge Conversion Command, CHRG
Charge/Discharge Conversion Command, CHRG (Pin 9) is used for operation mode change.
The converter change to the Charging mode when this signal is open.
The converter change to the Discharging mode when this signal short to SG.
There is behavior differs on operating mode and DIP switch setting. Please refer to

Alarm Clear Command, ALM CLR
During converter stoppage due to alarm, the latched alarm of this converter can be reset by Alarm Clear Command
ALMCLR (Pin 11) short to SG, then open again.

Service Power Supply, AUX 5V
Service Power Supply (Pin 15) is referenced to SG with approximately 4.7V.
A maximum of 20mA DC load can be connected. Current limit should be provided externally outside the converter.
*SG(Signal Ground) is functional insulation from converter ground.

At Manual CV Mode
Power conversion is between Generation and
Regeneration. Generate operation when pin#9 short to
SG. Regeneration mode when pin#9 open.
At Automatic Grid CV Mode
Power conversion is between Manual Grid Mode and
Automatic Grid Mode. Manual Grid Mode when pin#9
short to SG. Automatic Grid Mode when pin#9 open.
This command does not function at Automatic Battery
Mode.
