8. Troubleshooting checklist
 Components become hot and / or start to smoke.
Disconnect the connection to the supply voltage immediately!
Possible cause: The power supply was connected to the switching
input (IN) and the return conductor (RL). If components and
conductors have been visibly damaged, repair is usually not
technically or economically possible.
Possible cause: One or more components are soldered in the wrong
way. If you have assembled the module from a kit, carry out a visual
inspection (à sect. 6.) and rectify the defects if possible. If
components and conductor paths have been visibly damaged, repair
is usually not technically or economically possible.
 The connected light bulbs or LEDs do not light up.
Possible cause: The light bulbs or LEDs are connected to the
switching input instead of the return conductor. à Check the
connection. It is possible that the switching input has been
irreparably damaged.
Possible cause: A connected switch is closed. à Check the position
of the switch.
Possible cause: The LEDs are connected with the wrong polarity.
à Check the polarity of the LEDs.
Possible cause: One or more outputs are damaged due to overload.
à Send the module in for repair.
Possible cause: With a serial connection, too many LEDs are
connected in series. à Reduce the number of LEDs or increase the
supply voltage. Note that the maximum voltage is 22 V.
Possible cause: The light bulbs or LEDs are defective. à Check the
light bulbs / LEDs.
