Page 5: Safety Instructions
GBM-8 English 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. - Page 6 English GBM-8 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.

Page 7: Safe And Correct Soldering
GBM-8 English 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. - Page 8 English GBM-8 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.

Page 9: Operation Overview
The in- and outputs of the GBM-8 are galvanically isolated from each other. The eight outputs of the GBM-8 are arranged so as to be connected directly to the inputs of the s88-feedback modules S88-3** oder S88-4**. Voltage supply The GBM-8 is supplied directly via the rails. - Page 10 S88-3** oder S88-4**. The in- and outputs of the GBM-8 are isolated from each other by opto- couplers. Consequently interferences are filtered out and hum loops and fault currents are prevented effectively.

Page 11: Technical Specifications
English 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. -

There are several types in different package forms available. The type designation is printed on the component. Transistors for a low power rating (e.g. BC types) have a package in form of a half zylinder (SOT-package).

Page 18: Performing A Functional Check
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... - Page 19 GBM-8 English Testing layout 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.

Page 20: Connecting The Gbm-8
After performing a successful function test, disconnect the track busy indicator from the voltage supply and continue with the connection of the module. 8. Connecting the GBM-8 There are terminal strips soldered to the module which are used to insert and screw on the connecting cables. - Page 21 Each pair of connections for the rails is assigned to one connection for 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).

- Page 23 In order to display the busy status (e.g. in analogue displays), connect the cathodes (-) of the LEDs (with series resistors, e.g. 1 kΩ) to the outputs of the GBM-8. Connection diagram 2: Connecting LEDs Caution: Never use LEDs without series resistors, as in this case the LEDs will be destroyed quickly.
- Page 24 You can connect the inputs of digital feed back modules (e.g. s88- modules) 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 connection diagram 3.
