This unpowered F7-B model is designed to be used with the
LGB F7-A models. The electrical connection between the
"A-unit" and the "B-unit" is made with two cables (Fig. 1):
- a two-wire "track power" cable
- a four-wire "electronics" cable for sound and Multi-Train
System electronics.
In all arrangements of units (for example, A-A, A-B, A-B-A),
connect all the units together with two-wire track power
cables. However, only use the four-wire electronics cable
to connect B-units to A-units. Do not use the four-wire
electronics cable to connect two B-units together or two
A-units together.
Attention! If you connect two B-units together with the
four-wire sound cable, the sound amplifiers in the B-units
may be damaged.
Hints:
- One two-wire track power cable is included with each
A-unit.
Two four-wire electronics cables are included with each
B-unit.
- For proper operation of the horn and bell sounds, place
the B-unit on the track with the rear wall (Fig. 3) facing
the rear of the train (opposite the normal direction of
travel).
