4. Short Circuit or Overload
Overload Protection
A built-in overload protection protects the power pack in the event of an overload or a short circuit. The
locomotives will come to a stop, solenoid accessories cannot be controlled, and all lamps/lights con-
nected to the layout will go out.
The following procedure is recommended:
1. Unplug the power pack from the wall outlet.
2. Look on the layout for the cause of the short circuit and correct it.
3. After about 1 minute the overload protection
will go back to regular operation. After this period of time
has passed, the power pack can be used again.
If the power pack shuts off again without a short circuit being found, then the power pack is overloaded.
In this situation the number of users on the layout (locomotives, solenoid accessories, and lamps/lights)
must be reduced.
