Figure 1
Connection of a 4-aspect exit signals (left) and a 3-aspect entry signals (right). In this example the
signal module 10777 controls only the signal aspects in both signals.
Figure 2
Connection of a dwarf shunting signal at left and a block signal with the associated advance signal
at right. In these examples too the signal module 10777 only controls the signal aspects.
All signals are connected with their positive polarity to the contact "+". Further connections
depend on the type of signal and required signal aspects. Not all terminals are required at all
times. Sometimes wire connections are necessary to reproduce the aspects of foreign rail-
ways. Therefore you can interlink the outputs 1 to 6 arbitrarily.
If the module is used only to present the signal lights the connection is completed.
If the signal uses light bulbs the polarity of the bulb connections is unimportant. With these sig-
nals too the combined return wire is again connected to the "+" terminal of the signal module.
The outputs of the signal module (including "+" and "–") are protected against overloads, All
connected signals are automatically shut off when the combined load exceeds 300 mA.
The control functions for train operation remain active to prevent collisions even if the module
is overloaded.
