2. Safety instructions
Mechanical hazards
Cut wires can have sharp ends and can cause serious injuries. Watch out for sharp edges when you pick up the PCB.
Visibly damaged parts can cause unpredictable danger. Do not use damaged parts: recycle and replace them with new ones.
Electrical hazards
§ Touching powered, live components,
§ touching conducting components which are live due to malfunction,
§ short circuits,
§ connecting the circuit to another voltage than specified,
§ impermissibly high humidity,
§ condensation build up
can cause serious injury due to electrical shock. Take the following precautions to prevent this danger:
§ Never perform wiring on a powered module.
§ Assembling and mounting the kit should only be done in closed,
clean, dry rooms. Beware of humidity.
§ Only use low power for this module as described in this manual and
only use certified transformers.
§ Connect transformers and soldering irons only in approved mains
sockets installed by an authorised electrician.
§ Observe cable diameter requirements.
§ After condensation build up, allow a minimum of 2 hours for dispersion.
§ Use only original spare parts if you have to repair the kit or the
ready-built module.
Page 24
GBM-8 English
Fire risk
Touching flammable material with a hot soldering iron can cause fire, which can result in injury or death through burns or suffocation. Connect your soldering iron or soldering station only when actually needed. Always keep the soldering iron away from inflammable materials. Use a suitable soldering iron stand. Never leave a hot soldering iron or station unattended.
Thermal danger
A hot soldering iron or liquid solder accidentally touching your skin can cause skin burns. As a precaution:
§ use a heat-resistant mat during soldering,
§ always put the hot soldering iron in the soldering iron stand,
§ point the soldering iron tip carefully when soldering, and
§ remove liquid solder with a thick wet rag or wet sponge from the
soldering tip.
Dangerous environments
A working area that is too small or cramped is unsuitable and can cause accidents, fires and injury. Prevent this by working in a clean, dry room
with enough freedom of movement.
Other dangers
Children can cause any of the accidents mentioned above because they are inattentive and not responsible enough. Children under the age of 14 should not be allowed to work with this kit or the ready-built module.
Little children can swallow small components with sharp edges, with fatal results! Do not allow components to reach small children.
In schools, training centres, clubs and workshops, assembly must be supervised by qualified personnel.
In industrial institutions, health and safety regulations applying to electronic work must be adhered to.

3. Safe and correct soldering
Caution:
! Incorrect soldering can cause dangers through fires and heat. Avoid these dangers by reading and following the directions given in the chapter Safety instructions.
§ Use a small soldering iron with max. 30 Watt. Keep the soldering tip
clean so the heat of the soldering iron is applied to the solder point effectively.
§ Only use electronic tin solder with flux.
§ When soldering electronic circuits never use soldering-water or
soldering grease. They contain acids that can corrode components and copper tracks.
§ Solder quickly: holding the iron on the joints longer than necessary
can destroy components and can damage copper tracks or soldering eyes.
§ Observe correct polarity orientation of semi-conductors, LEDs,
electrolytic capacitors and integrated circuits before soldering and ensure that the solder time does not exceed 5 seconds, otherwise components can be damaged.
§ Apply the soldering tip to the soldering spot in such a way that the part
and the soldering eye are heated at the same time. Simultaneously add solder (not too much). As soon as the solder becomes liquid take it away. Hold the soldering tip at the spot for a few seconds so that the solder flows into the joint, then remove the soldering iron.
§ Do not move the component for about 5 seconds after soldering.
§ To make a good soldering joint you must use a clean and
unoxidised soldering tip. Clean the soldering tip with a damp piece of cloth, a damp sponge or a piece of silicon cloth.
§ Cut the wires after soldering directly above the PCB solder side with
a side cutter.
Page 26
GBM-8 English
§ After placing the parts, please double check for correct polarity.
Check the PCB tracks for solder bridges and short circuits created by accident. This would cause faulty operation or, in the worst case, damage. You can remove excess solder by putting a clean soldering tip on the spot. The solder will become liquid again and flow from the soldering spot to the soldering tip.
4. Operation overview
The track busy indicator GBM-8 can be used in analogue (d.c. or a.c.) layouts as well as in digital layouts. The module can supervise a maximum of eight track sections.
The GBM-8 is internally divided into four sections with two track busy indicators each, which can be connected to a maximum of four different
booster or transformer sections.
Detecting vehicles
With a sensivity of 5 mA the GBM-8 detects reliably locomotives and carriages with lighting, but not vehicles not consuming current of their own.
Hint: As a rule, the small current flowing after painting a carriage´s axle with resistive lacquer is not high enough to be detected by the GBM-8. For this application the fourfold track busy indicator GBM-1** can be used.
Electric consumers located in a switched off track section can be detected by the GBM-8 when an additional resistor is mounted in parallel to the switch.
Due to technical principles, with (analogue) d.c. layouts the GBM-8 can only detect vehicles driving into the supervised track sections in a particular direction. In case the detection of vehicles from both directions is required, the track busy indicator GBM-1** can be used.
Page 27
English GBM-8
Evaluating and displaying the busy messages
As soon as the GBM-8 detects an electric current consumer in a connected track section, the linked output is internally connected to the output M. This way, the output of the GBM-8 works like a switch switching to earth. Especially in analogue displays, you can display the busy messages with LEDs (together with suitable series resistors) connected to the outputs. The outputs of the GBM-8 are suitable for a load of maximum 50 mA each. For that reason they are not suitable for the connection of electric light bulbs, relays or subordinate circuits with a current consumption of more than 50 mA. For these applications the fourfold track busy indicator GBM-1** can be used.
In digital layouts, digital feedback modules (e.g. s88-feedback modules) can be connected to the outputs. The eight outputs of the GBM-8 are arranged so as to be connected directly to the inputs of the s88­feedback modules S88-3** oder S88-4**.
The in- and outputs of the GBM-8 are isolated from each other by opto­couplers. Consequently interferences are filtered out and hum loops and fault currents are prevented effectively.

6. Assembling the GBM-8
You can skip this part if you have purchased a ready-built module or a complete unit.
Preparation
Put the sorted components in front of you on your workbench. The separate electronic components have the following special features you
should take into account to prevent mistakes in assembling:
Resistors
Resistors reduce current. Their mounting orientation is of no importance. The value of resistors for smaller power ratings is indicated through colour rings. Every colour stands for another figure. The colour ring in brackets indicates the tolerance of the resistor which here is of no importance.
Value Colour rings 1 k brown - black - red (gold)
4,7 kyellow - violet - red (gold)
Diodes
Diodes allow the current to pass through in one direction only (forward direction), simultaneously the voltage is reduced by 0,3 to 0,8 V. Exceeding of the limit voltage always will destroy
the diode, and allow current to flow in the reverse direction. The diode type is printed on the body. Diodes must be mounted in a given direction. The negative end is
marked with a ring. This is shown in the PCB layout.
Page 29
English GBM-8
Transistors
Transistors are current amplifiers which convert low signals into stronger ones. They have three contacts. As they are polarized, they have to be mounted in a certain direction.
BC-Types have a housing in form of a half cylinder (SOT-
housing). The cross section is shown in the PCB layout which
determines the mounting orientation.
Integrated circuits (ICs)
Depending on the type, ICs fulfil various tasks. They are
polarized and therefore have to be mounted in a certain
direction. The most common housing form is the so-called
"DIL"-housing, from which 4, 6, 8, 14, 16, 18 or more "legs"
(pins) are arranged along the long sides. The mounting orientation is shown by a semicircular or circular marking
at the end of the housing, which is also shown on the PCB layout. ICs are sensitive to damage during soldering (heat, electrostatic
charging). For that reason in the place of the ICs IC sockets are soldered in, in which the ICs are inserted later. The mounting orientation of the sockets is preset as well. The markings on the PCB, the socket and the IC must lie on top of each other after mounting.
Opto couplers
Opto couplers are ICs, which work similar to laser beam switches. They combine in one housing a light emitting diode and a photo transistor. Their task is the transmittion of information without galvanic connection. Normally they are in a DIL-housing with 4, 6 or 8 pins.
Terminal strips
Terminal strips are solder-in screw-type terminals. They provide a solder-free and safe connection of the cables to the circuit, which can still be seperated any time. When several terminal strips have to be mounted side by side, they have to be put together before mounting.
Page 30
GBM-8 English
Assembling the kit
Caution:
! Diodes, transistors, Ics and opto couplers should be inserted in the right direction! If you solder them the wrong way around the affected parts can be damaged when you connect the power. In the worst case the whole circuit can be damaged. At the best, a wrongly
connected part will not function.
Start the assembly with the resistors. First solder the components on the solder side of the PCB and then cut the excess wires with the side cutter.
Then insert the four wire bridges Br1 to Br4. Use the off-cut wires of the resistors.
Next solder in the IC-sockets. They have to be mounted according to the marking on the PCB.
Continue the assembly with the transistor, the diodes and the terminal strips. Put together the terminal strips before mounting them.
Finally, insert the opto couplers into the soldered IC-sockets.
Caution:
! Do not touch the ICs without first discharging yourself by touching a
radiator or other grounded metal parts. Do not bend the "legs" of the ICs when inserting them into the sockets. Check that the markings on the PCB, the socket and the IC show to the same direction.
Page 31
English GBM-8
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 check
It is recommended to perform a functional test after mounting the GBM-8 and before installing it into the layout. In order to simulate a load in a supervised section, use a resistor. A small auxiliary circuit made of a LED, a series resistor 1K and a damping diode, is used to display the busy status. The required components are included in the package.
Follow the connections diagram fig. 3 and the list in section 7. First, make the following connections in order to check if the GBM-8 properly detects and displays the busy status:
1. model railway transformer à connections V1a, V1b and M
2. auxiliary circuit à connections A1 and V1a
3. resistor 1K à connections G1 and V1a
Caution:
! Never connect electric light bulbs to the outputs as these consume more than 50 mA current, as a rule. The outputs which are designed for a maximum current of 50 mA would be destroyed when putting them into operation.
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.
Page 32
GBM-8 English 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).
If the funcitional test is not successful for one or several outputs, check if the opto-couplers and the diodes have been mounted polarized correctly. Follow the hints in section 8, as well.
Caution:
! When a component gets too hot, disconnect the module immediately from the power supply. Risk of short circuit! Check the assembly.
7. Connecting the GBM-8
There are terminal strips soldered to the module´s connections, used to plug in and screw on the connection cables. Each connection for the rails is internally connected to one output. Each pair of connections for the rails is assigned to one connection for the power supply.

English GBM-8 Follow the connections diagrams fig. 4, 5 and 6.
Connecting the power supply
Connect the connections for the power supply of the GBM-8 (V1a and V1b or V2a and V2b etc.) to the rail outputs of the driving transformer (in analogue layouts) or the rail outputs of the boosters (in digital layouts). The polarity is not of importance.
As the need arises, you can connect the connections for the power supply (V1, V2, V3, V4) either in parallel to the rail outputs of one booster or transformer or to maximum four different transformers or boosters.
Connecting the rail sections
The busy status can only be reported trouble free, when with each supervised section one conductor is isolated at both ends. In 3-rail systems isolate the middle conductor, in digital 2-rail systems (d.c. layouts) one of the two rails and in analogue 2-rail systems the "-" rail. Pay attention to the fact that, due to technical principles, in analogue 2­rail systems only vehicles driving into the track section in one particular direction are detected.
Connect the isolated conductor (the middle conductor or the isolated rail) of the supervised rail section to one of the rail connections of the GBM-8 (e.g. G1).
Connect the connection "a" for the power supply (e.g. V1a) to the rail conductor which has not been isolated.
Be sure to use the connections for the power supply and the rails which are assigned to each other (e.g. V3a and V3b and G5 and G6).
Connecting LEDs
In order to display the busy status (e.g. in analogue displays), connect the cathodes (-) of the LEDs (with series resistors, e.g. 1 K) to the outputs of the GBM-8. Do not use the driving transformer for the power
Page 34
GBM-8 English supply of the LEDs but a separate transformer, for instance one used to
supply other lighting circuits. When connecting the LEDs to an a.c. transformer, you should mount an additional damping diode (e.g. 1N400x, x=2...7) and a capacitor with a value between 10 and 100 µF and an electrical strength of minimum 25 V according to fig. 5.
Caution:
! Never connect electric light bulbs to the outputs as these consume more than 50 mA current, as a rule. The outputs which are designed for a maximum current of 50 mA would be destroyed when putting them into operation.
Caution:
! Never use LEDs without series resistors, as in this case the LEDs will be destroyed quickly. Apart from that the overcurrent resulting may damage the opto-couplers on the module.
Connection to digital feed back modules
You can connect the inputs of digital feed back modules (e.g. s88­modules) directly to the outputs of the GBM-8. Connect the earth output of the feed back module to the connection M of the GBM-8 according to fig. 6.
Supervising switched off rail sections
Rail sections to be switched off during operation (e.g. in a shadow station) can be supervised with the track busy indicator, as well. For that purpose you have to mount a resistor of 1 k into the lead-in wire of the rail section concerned so that it bridges the switch when the rail section is switched off (see fig. 4 connection to G2)
Page 35
