Automatic Switching Off Of The Track Voltage - tams elektronik B-6 Manual

Booster B-6
6.1.2 "Display and RGB LEDs"). The track voltage must then always be switched on by
pressing the STOP-GO button (several times if necessary).

6.3.3. Automatic switching off of the track voltage

The Booster B-6 automatically switches off the track voltage at the output in the following
cases in order to prevent damage to the booster, connected digital devices, vehicles and/or
tracks:
Short circuit on the tracks
The internal short-circuit cut-off ensures that in the event of a short-circuit on the tracks, the
track voltage is automatically switched off at the track output. The short circuit is indicated
by:

Display: Sh.

RGB LEDs: flashing of the LEDs in violet and red.
If the short circuit is eliminated within the set time, the booster automatically switches the
voltage on the track output back on.
You have the following setting options (→ section 5.2 "Main track programming"):

Restart time after short circuit: 4 ... 10 seconds (input values for CV 7: 34 ... 40).

Maximum track current (cut-off current in case of short circuit): 2 ... 6 A (input values for
CV 7: 42 ... 46). To effectively prevent damage in the event of a short circuit, the short-
circuit sensitivity must not be set too high (→ section 5 "Recommendations for settings").

Restart time after 5 times short circuit: 0 ... 90 seconds (input values for CV 7: 100 ...
109).

Time until the short-circuit cut-off responds: 20 ... 200 ms (input values for CV 7: 110 ...
119)
If the short-circuit feedback line is connected, the B-6 sends a short-circuit feedback to the
DCC control unit, which switches off the track voltage at the output of the booster (and
possibly other boosters) in case of a short-circuit.
Overheating of the booster ("excess temperature")
The booster can overheat if it cannot dissipate the heat generated during operation to the
environment. Therefore, keep a distance of at least 20 cm between the side surfaces, the top
and the rear sides to surrounding surfaces. Also ensure that the booster is not exposed to
very high ambient temperatures or direct sunlight.
Triggering the watchdog
When the watchdog is activated, the central unit (usually controlled by PC software) sends a
DCC turnout setting command to a turnout address assigned to the B-6 at intervals of approx.
5 seconds. As soon as the booster no longer receives these commands, it automatically
switches off the track voltage.
