GBM-8

7. Performing a functional check

It is recommended to perform a functional test before installing the
GBM-8 into the layout. Test the module with a small auxiliary circuit.
The required components are included in the package.
Follow   the   connections   diagram   "Testing   layout"   and   the   list
"Assignment   of   the   booster   sections   or   transformers   and   the   rail
sections to the GBM-8" in section 8. There are terminal strips soldered
to the module which are used to insert and screw on the connecting
cables. 

Test for rail section 1 

GBM-8

Connection to

V1a, V1b and M

Transformer 

A1

Auxiliary circuit made of:
LED, series resistor 

k

W

 and damping diode. 

Observe the polarity of the LED and the damping 
diode! With wired LEDs the longer lead is always 
the anode (positive pole). The negative end of the
damping diode is marked with a ring. 

G1 and V1a

Resistor 1 k

W   

 simulation of a load in the 

supervised rail section 1

After connecting the transformer with the power supply, the LED 
should light. Disconnect the connection between G1 and the resistor, 
the LED should go out.

Repeat the test for all other track sections. Be sure to connect the 
connections for the power supply, the rails and the output, which are 
assigned to each other (e.g. V3a, V3b, G5 and A5).
