Symptom
Mains switch
When the battery is low, a high logic level output is generated by the MCU, which then
enables the mains power.
Troubleshooting
Symptoms and corrective action
– Set-up the system as per the hardware installation procedure described in
– Check the mains enable signal on P6. A high logic level indicates that the battery
– Reset the system by pressing the reset button (PB1).
– Check the battery type and polarity. Only 12 V battery can be applied to this system. If
– Check that the LED lamp is available.
– Set-up the system as per the hardware installation procedure described in
– Reset the system by pressing the reset button (PB1).
– Check that it is not too dark to enable the solar panel’s output.
– Check that the solar panel is available.
– Try to cool down the LED lamp.
– Check that the LED lamp’s lifecycle is still valid.
voltage is too low to power the LED light. This status will persist until the battery is fully
charged.
the battery has previously been connected reversely, replace the fuse (F1) with a new
one.
