5) When using external signal connector CN
The following explains how to control with external signal connector CN without using RS-485.
The following explains how to operate the EZA in the Manual CV mode via CN.
Also, set the address on RS-485 to "0" and the communication speed to 19.2 kbps.
Set the terminal voltage on both the grid side and the battery side of the EZA to 0
V. As shown in the photo below, set only 3 of the DIP switch on the back to ON.
Apply a voltage of 120V or more to the EZA grid and battery terminals. At this time,
do not apply a voltage exceeding the upper limit of the specifications. If no voltage is
applied to the grid side and battery side, the power of the control board can be
supplied from CN pin 16 “24Vi” and the parameter can be set. In this case, you set
once the voltage of pin 16 to 0V, and then changes the DIP switch and the rotary
switch. Next you reapply the voltage.
This operation is not necessary if the DIP switch and rotary switch are not operated.
②
Restart the control board.
①
Set EZA to operation via CN.
If the operation setting is via CN, EZA will not
accept start commands via RS-485.
However, since Waiting Mode command is
accepted, it is possible to stop via RS485.
Refer to p10 of the operation manual and p6
of the communication manual when
operating in other modes or changing the
address.
Set the rotary switch on the front panel as
shown in the picture to the right.
※
The factory setting is the above setting.
The control board reads the values of DIP switch and rotary switch at restart.
The control board is also restarted by applying the voltage to either the
battery or grid side.
