Caution:
If a component gets too hot, disconnect the module and power supply
from the mains immediately. Possible short circuit! Check the
assembly!
After performing a successful functional test, disconnect power from the
double flashlight. Disconnect the LEDs from the module and install the
module. Proceed as described in the functional test.
Connectings several LEDs to one output
You can connect up to two LEDs in parallel to one output or several
LEDs in series to one output. You can determine the number of the
LEDs that can be connected in series to one output from the following
formula:
(number of LEDs + 3) x 1,5 < power supply
Using as a single flashlight
The module can also be used as a single flashlight. For that purpose
you must replace one LED with a wire bridge. Compared to when LEDs
are connected to both outputs, the flashing frequency is a little faster.
Connection to a locomotive or a function decoder
Connect "GND" to the output of the decoder you want to use for
switching the double flashlight, and "Uin" or "12V" to the return
conductor of the decoder.
