1. Getting started
The instructions will help you step by step with the safe and proper installation and use of
your track occupancy indicator. Before you put the track occupancy indicator into operation,
read this manual completely, especially the safety instructions and the section on possible
errors and their elimination. You will then know what you have to pay attention to and thus
avoid errors that sometimes can only be rectified with a lot of effort.
Keep the instructions in a safe place so that you can restore functionality later in the event of
any malfunctions. 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. Stranded wires consist
of several thin individual wires and are therefore more flexible than rigid wires with the same
copper cross-section. Recommended cross-sections:
Connections to the tracks and the booster / the driving transformer: > 0.25 mm²
Connections to digital feedback modules: > 0,10 mm²
Displaying the occupancy messages
If you want to display the busy signals, you will need
LEDs and suitable series resistors (e.g. 1 k
)
for connection to AC voltage additionally:
1 electrolytic capacitor 10...100 µF / 25 V
1 diode 1N400x, x = 2...7
Monitoring of switched off track sections
To be able to monitor track sections that are to be switched off during operation (e.g. in the
staging yard), you need additional resistors with a value of max. 1.5 k
.
1.3. Intended use
The track occupancy indicator is intended for use in model railway layouts as specified in the
instructions. Any other use is not in accordance with the intended use and will result in the
loss of the warranty claim. Intended use also includes reading, understanding and following all
parts of the instructions. The track occupancy indicator is not intended to be used by children
under the age of 14.
