GBM-1

3.6. Performing a visual check

Perform a visual check after the assembly of the module and remove faults if necessary:

Remove all loose parts, wire ends or drops of solder from the PCB. Remove all sharp wire
ends.

Check that solder contacts which are close to each other are not unintentionally connected
to each other. Risk of short circuit!

Check that all components are polarised correctly.
When you have remedied all faults, go on to the next part.

3.7. Performing a functional test

It is recommended to perform a functional test before installing the assembled kit into the
layout. You will need a light bulb for the function test.
There are terminal strips soldered to the module which are used to insert and screw on the
connecting cables. Connect the bulb to the four inputs of the track busy indicator one after
the other.

→ Now the lamp and the LED at output A1 should light.
→ Repeat the test for E2, E3 und E4.
Caution:
!
If a component gets too hot, disconnect the track busy indicator from the mains
immediately. Possible short circuit! Check the assembly again.
After successful completion of the function test, disconnect the track occupancy detector from
the supply voltage again and the light bulb from the input of the GBM.
