Introduction To DCS
Recommended Wiring Method - Older Transformers
Older transformers, like the Lionel postwar ZW or KW models
employ a bi-metallic strip to act as a circuit breaker. The strip
responds to heat as high current flows through the transformer. If
enough heat is generated by the high current, the strip will open
the circuit and prevent further current from flowing out of the
transformer. The bi-metallic strip is not a precise overload protec-
tion device and does not measure the current. As a result, it may
not trip when excessive amps are being generated by the short
circuit. Should the strip thus fail to trip, excessive and potentially
harmful current could be sent through the TIU.
MTH therefore recommends that any user employing an older
transformer that does not meet today’s U.L. standards install
inline fuses or circuit breakers between the transformer and the TIU input channels. An AG3C
“fast-acting” or “fast-blow” fuse rated at 15 amps would be suitable protection. These can be
obtained from most hardware or electronic stores including Radio Shack. Users will also need
an inline fuse holder to house the fuse. Radio Shack sells a heavy duty model, part number
27-1217.
Recommended Wiring Method -
Electronic Transformers
Any transformer employing two parts, a brick (step down transformer) and a controller (used
to vary the voltage output) may cause operational problems due to low power or poor DCS
signal. To correct this problem, MTH recommends connecting only the brick to the TIU
inputs. In addition, check the output voltage
of the transformer; it should not exceed 22
volts (or 18 volts if lighted cars are used on
the track).
When using the Z-500, Z750 or Z1000 elec-
tronic type transformer use an adapter cable,
MTH item 50-1017, to connect the brick
directly to the TIU input as shown below. DO
NOT use the controller portion of an elec-
tronic type transformer.
