Earth connection
In systems with continuous mass (e.g. 3 rail systems fed with boosters with continuous mass)
the earth connection between s88 feedback module and other components is made via the
earth line in the s88 bus cable.
In digital layouts with boosters galvanically separated, the earth connection X2 of the S88-3
module has to be connected to a separate earth line or to mass of the rails. This applies
especially to layouts with DCC conform boosters, but as well to layouts controlled by the
central station of Märklin** or the Ecos of ESU**.
Connecting the track sections and the earth connection
There are terminal strips soldered to the inputs and to the earth connection of the S88-3
which are used to insert and screw on the connecting wires.
Functional test
First connect the output "OUT" of the S88-3 to the central unit, the memory or the interface
for a functional test. Fix a connecting cable to the module's earth connection X2 and connect
it one after the other to all 16 inputs. Check if the correct status message is shown for all
inputs.
Installing in the layout
After performing a successful functional test install the S88-3 at the desired place on your
model railway. Connect the inputs 1 to 16 to the mass contacts and connect the module to
the central unit, the memory or the interface or to another feedback module.
