Battery voltage<12V
(LED on)
Battery voltage<11.7V
(LED flashing)
When the battery voltage is indicated as low, it is recommended to use the remaining energy economically.
The charge controller will subsequently switch off the load.
Load status display
In case of deep discharge or overload/short-circuit, the load output is switched off. This is indicated by:
Normal operation
(LED off)
Low voltage
disconnect
(LED on)
Overload or Short-circuit
of load (LED flashing)
Low Voltage Disconnect Function (LVD)
The controller is equipped with a low voltage disconnection function to protect the battery against a deep
discharge: This function is controlled by the voltage, and automatically switches off the load output at a
battery voltage lower than 11.5 V.
As soon as the battery reaches a voltage of 12.5V the load output is switched on again.
