6. Checklist for troubleshooting and error correction
Warning: If you notice a strong heat development, immediately disconnect the Power-
Splitter and the booster / digital central unit from the supply voltage. Fire hazard! Send in
the Power-Splitter for testing.
6.1. No supply to the booster sections
All LEDs permanently switched off
 Possible cause: The connection to the booster is faulty.  Check the connections.
Only LED for string 3 permanently switched off
Booster section 3 is not supplied with power, although string 3 is correctly connected to the
rails and the output of the Power-Splitter.
 Possible cause: A jumper is plugged into pins 4. This limits the number of active strings to
two (strings 1 and 2).  Remove the jumper.
LEDs light up
Depending on the number of active strings, the LEDs for strings 1 and 2 or all three LEDs light
up. The strings are still not supplied with power.
 Possible cause: The connection to the rails is faulty.  Check the connections.
6.2. Problems with short circuit disconnection
Short circuit cut-off without exceeding the current in the booster sections
The booster switches off all booster sections although the maximum current in the booster
sections has not been exceeded (2 or 3 A depending on the setting).
The booster switches off all booster sections although it is set so that only the affected
booster section is to be switched off in the event of a short circuit.
 Possible cause: The maximum output current of the booster has been exceeded. It is
smaller than the sum of the current in the booster sections.  Reduce the current
consumption in the booster sections or the number of active booster sections (from 3 to 2).
