+ Leakage : At any contact between (+)polarity-earth in DC supply, the LED become active.

- Leakage : At any contact between (-)polarity-earth in DC supply, the LED become active.

High Temperature : When the internal temperature of the rectifier reaches the temperature value in the settings, the LED become active.

Low Temperature : As soon as the rectifier internal temperature reaches the factory set 5°C, the LED becomes active.

DC High : When the output of the rectifier reaches the DC High value in the settings, the LED becomes active.

DC Low : When the output of the rectifier reaches the DC Low value in the settings, the LED becomes active.

AC High : When the AC voltage reaches the AC High value in the rectifier settings, the LED becomes active.

AC Low : When the AC voltage reaches the AC Low value in the rectifier settings, the LED becomes active.

AC ON : LED is active when AC input supply is at nominal value.

Over Load : When the DC output on the rectifier exceeds the total current value, the LED becomes active.

Current Limitation: When the battery output on the rectifier reaches the battery charging current value in the settings section, the LEDs becomes active and the rectifier starts to work in current limiting mode.

Battery Critical : When the battery voltage reaches below the battery alarm value in the setting, LED becomes active.

RTC Battery Low : There is an RTC on the rectifier. When the device is de-energized, RTC works with the battery it is connected to. When the voltage of the battery drops below the factory set value, LED is activated.

Battery Alarm : If Y is selected in the Battery Fail Y/N section in the rectifier setup menu and the battery voltages fall below the DC voltage set in the Battery Fail(y) section, the LED will be active.

Normal Charge : When the rectifier is working in Normal Charge mode, the LED is active.

Boost Charge : When the rectifier is working in Boost Charge mode, the LED is active.
