5. Connections for the Controler 67025
The 67025 controller requires the 66191 trans
former included with this starter sets as a source
of power.
Important Information:
The 67025 controller may be connected only to
the 66191 transformer. No other transformer may
be used with this controller!
5.1 Connecting the Controler 67025 to the
Transformer.
The 67025 controller requires the transformer only
as a source of power. Therefore, only the black
connecting plug (2) has to be plugged into the
socket (3) on the 67025 controller - see Figure .
5.2 Connecting a Model Railroad Layout to the
Controler 67025
The red and the brown connecting wires on the
controller can only be connected to Märklin C
Track. C Track is also included in this starter set.
Connect the red wire (4) with the spade connec
tor from the Controler to the contact finger on the
underside of the track, which is connected to the
center conductor. Connect the brown wire (5) with
the spade connector from the Controler to the
contact finger on the underside of the track,
4. Short Circuit or Overload
Overload protection
A built-in thermal switch protects the Transformer
from damage in case of an overload or a short
circuit. Locomotives on the layout will come to
a stop, accessories cannot be operated and all
lamps connected to the Transformer will go out.
The following procedure is recommended:
1. Unplug the power cords for all transformers
from their outlets.
2. Look for the cause of the short circuit on the
layout and correct it.
3. After about 1 minute the thermal switch will
go back to being on. After this amount of time
has passed, all Transformers can be placed in
operation again.
If the Transformer should shut off again and
you are unable to locate a short circuit, then
the Transformer is overloaded. In this case the
number of users connected to the Transformer
must be reduced.
