There are four buttons on the controller. Buttons definition are, respectively, set (SET), down
(DOWN), up (UP), exit (ESC). Functions are as follows:
In standby mode, when press the DOWN button, the data of battery voltage (V battery),
photovoltaic panels voltage (V PV), the charging current (I charge) and discharging current (I Load)
will switch at the corresponding time in the display area;
In standby mode, set the system parameter by the SET button. The order for system parameter is
under voltage (Under), low voltage recovery (Under- R), over voltage (OVD), over voltage recovery
(OVD- R), floating charge (FLOAT), improving charge (BCV), equalizing charge (ECV), the first
Time control (Time), the second Time control (Time1), the thrid Time control (Time2) and light
control voltage (L- CON- V). After pressing SET button, according to the parameters order,
parameter will increase by 0.1 when pressing the UP button (decrease by 0.1 when pressing the
DOWN button). When finish setting a certain parameter, please press the SET button again to save
data. When press ESC button in any parameter Setting interface, the controller will return to the
standby interface.
Warning: When set the light control voltage, the light control OPEN voltage must be
greater than the light control CLOSE voltage. otherwise the light control cannot work
normally.
For some parameters which may affect the system security, you can set them by combined buttons.
In standby mode, when press SET and DOWN buttons for 3 seconds at the same time, the system
will restore to factory Settings. When press SET and UP buttons for 3 seconds at the same time, Id
will show at the top two of the display area. Then press UP or DOWN buttons to set the system Id
(address).
E. Light control and Time control
There are two kinds of working modes for the controller- street light mode and household use mode.
Light control and time control can be set under the street light mode.
Press SET button continuously till the TIME icon lights up. You can set the working mode and the
length of the first Time control. When the data sets to 0, the controller is in household use mode.
When the data is not 0, the controller is in street lamp mode. And the data is the length of the first
Time control (that is, the first light working-time). Press SET button again to save the data and the
current setting data shows in the display area.
