connected during the daytime and the array is wired correctly.
※ If the SOLAR is disconnected during installation, the controller will see this as the
first night and the length of night will be too short. This will only affect ON/OFF/ON
settings, and will automatically be corrected over 4 days. If the PV array is
disconnected, it is best to disconnect the battery and restart the microcontroller before
leaving the site.
※ Remember that the Solar array will generate power whenever in sunlight. Also, be
careful not to shortcircuit the PV array while connected to the controller, since this
will damage the controller.
6. Connect the LIGHT last. If the red LED indicator lights, the battery capacity is low
and should be charged before completing the system installation
7. Set the DIP Switch 1 and 2 for the voltage system, set the DIP Switch 3, 4, 5 for
battery charging algorithm, set the DIP Switch 6 for Auto/Manual Equalization or
Load reconnect, set the DIP Switch 7 for Light or Load Control
8. For most effective surge protection, it is recommended that the negative system
conductor be properly grounded.
9. Turn the rotary LIGHTING CONTROL switch to the lighting option desired.
