!
Caution:
Do not power up the module yet.
Check all nuts, pins and connections as well as the mechanical
connections for correct assembly.
The following points are inapplicable if you have purchased a ready-
built module.
§
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.

Performing a functional test

Even if you have purchased a ready-built module, check all functions.
Transport damage can never be excluded.
!
Caution:
Do not connect the module to the power supply yet.
Check the functions of the module with a test lamp or bulb. Connect
the four functional sections of the track-busy indicator one after the
other with the lamp. Proceed as follows:
There are terminal strips soldered to the in- and outputs. Insert the
connecting cables into the relevant terminals and fasten the screws.
First connect the test lamp with the input E1 and the voltage supply "~" of the
track busy indicator (not with earth!). Connect the module to the transformer.
Follow fig. 3 "connections". Connect the transformer to the mains.
The test lamp and the LED at output A1 should now light. Disconnect
the test lamp from input E1. The LED at output A1 should go off.
Repeat the test with the other three functional sections of the track-
busy indicator.
