Performing A Functional Test - tams elektronik PZS-3 Manual

PZS-3
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.

Performing a functional test

Perform the functional test even if you have purchased a ready-built
module, as damages in transit cannot be excluded.
You don't have to test all functions of the module before connecting it
to the model railway layout. The effort involved would offer no
advantages compared to testing the module after having connected it
to the model railway layout. The functional test as described should
only be carried out to test if the module basically works.
§
Connect the electric light bulb to the connecting points 9 and 13.
§
Connect the two connections of the driving transformer to the
connecting points 3 and 11, the polarity is of no importance. Turn
on the speed knob of the driving transformer.
§
Connect the supplying transformer to the connecting points 2 and
10 and switch it on.
§
The electic light bulb should slowly get brighter.
In case the bulb does not light different faults can be the reason for it.
You will find a list of possible faults and how to cure them in the
chapter „FAQ".
