Page 4: Getting Started
If you pass the track occupancy indicator on to another person, also give the instructions with it. 1.1. Contents of the package 1 ready-built and tested circuit board GBM-8.2 (item no. 52-01186-01) or 1 track occupancy indicator GBM-8.2 in housing (item no. 52-01187-01) 1.2. Accessories Connection cables The use of stranded wire is recommended for making the connections. -
Page 5: Safety Instructions
GBM-8.2 1.4. Safety instructions Note: The track occupancy indicator contains integrated circuits (ICs). These are sensitive to electrostatic charging. Therefore, do not touch these components until you have "discharged" yourself. For this purpose, e.g. a grip on a radiator is sufficient. -
Page 6: Operation Overview
To display the busy messages, LEDs (with suitable series resistors) can be connected to the outputs of the GBM-8.2. Since the outputs of the GBM-8 can be loaded with a maximum of 50 mA each, they are not suitable for connecting incandescent lamps, relays or downstream circuits with a higher current consumption. -
Page 7: Use In Digital Systems
GBM-8.2 2.2. Use in digital systems The GBM-8.2 can be used independently of the digital format with which the layout is controlled. A typical application in digital systems is the combination with feedback modules that read in ground contacts (e.g. s88 feedback modules). The eight outputs of the GBM-8.2 are arranged in such a way that they can be directly connected to the inputs of the s88 feedback modules from the Tams Elektronik product range (e.g. -
Page 8: Connections Gbm-8.2
Please note: If you use a DC voltage transformer as the + / ~ driving transformer, you must always observe the polarity when - / connecting it. If you use an AC voltage transformer, the polarity is not important. 8 | Connections GBM-8.2... - Page 9 Track sections that are to be switched off during operation (e.g. in a staging yard) can also be monitored with the GBM-8.2. For this purpose, a resistor with a value < 1.5 kW must be installed in the supply line to the track section concerned in such a way that it bridges the switch in the switched-off state.

Page 10: Connection Of Leds
No incandescent lamps! Never connect incandescent lamps to the outputs, as they usually consume more than 50 mA of current. The outputs of the GBM-8.2, which are designed for a maximum current of 50 mA, would be destroyed during commissioning! -
Page 11: Connection Of Digital Feedback Modules
You can connect the inputs of digital feedback modules that switch to ground (e.g. s88 feedback modules) directly to the outputs of the GBM-8.2. Connect the ground output of the feedback module to one of the two connections M of the GBM-8.2. -

Page 13: Checklist For Troubleshooting And Error Correction
Possible causes: One or more connections are faulty. à Check the connections. The GBM-8.2 is defective. à Send the track occupancy indcator in for inspection. Connected LEDs do not light up Possible causes: The power supply is interrupted. à Check the connection of the LEDs and the track occupancy detector to the transformer supplying the LEDs. -
