OUTPUT led indicator

LED indicators

The Buck-Boost DC-DC converter is equipped with two RGB LEDs.
The IN LED has the following functions:
Green: The converter is switched on (by the engine running detection, or by applying a voltage on pin 1).
Yellow: The input voltage is lower than the set threshold to allow the converter
to switch on.
Red: The internal temperature is higher than the set safety threshold. The converter is
switched on
Blue: Short light pulses = the engine running detection is active, the converter turns on after a delay.
Flashes slowly = the converter is switched off and blocked for switching on due to
A too low input voltage.
The OUT LED has the following functions:
Green: The converter is switched off. The connected battery has a correct terminal voltage.
Yellow: The converter is switched off. The connected battery has too low a terminal voltage.
Red: The converter is switched off. The connected battery is empty or the battery is not connected.
Purple: The converter is switched on and supplies power to the connected battery and/or electrical
consuming points.
Flashing purple: The converter is switched off. When the converter starts up, the set voltage of the
second battery is too low (safety circuit 31 is active).
The normal alerts of each LED blinks slowly for power saving (Setting 27).
Engine running detection
The converter has a unique engine running detection in order to be able to detect a running vehicle
engine. This prevents the converter from charging the starter battery if the alternator does not supply
power.
The converter is switched on:
When the engine is running and the supply voltage is >= (adjustable) volts and any (adjustable) minute
blocking is over.
Pin 1 input (as an alternative to the engine running detection)
The converter may also be switched on with a switch or relay contact.
Switch on:
The converter is switched on:
If pin 1 input >= 2 volts, and the supply voltage is >= (adjustable) volts and any blocking is over.
Important when installing!
