BW/PowerHouse operation
| Type
BW functions |
 |
 our
Type BW provides a total output of 5 amps. The track (variable) output
will deliver 5 amps to the track when no load is connected to the
accessory (fixed) “U” terminals. The accessory terminals
also provide a maximum output of 5 amps, but the total output cannot
exceed 5 amps. For example, if your track output is 3 amps, you have
2 amps of fixed output to run your accessories. This built-in flexibility
will provide power for virtually any small-to-intermediate-sized railroad.
Available voltage varies depending on how
much load is on the two outputs. Generally, track voltage is 0-18VAC.
Accessory voltage is 12VAC.
Type BW will operate trains up to and including
dual-motored AC engines. To operate at this level of track power,
it may be necessary
to disconnect any accessory load.

Always clean and lubricate engines for best results. It may be necessary
to power up slowly at this load to prevent surge current from tripping
Type BW’s protection circuit.
Type BW will operate any single locomotive
and consist. However, when a locomotive with Railsounds is pulling
several illuminated cars, the current will approach the trip point
at certain times. In this case, a light touch on the throttle may
be required.

Unlike
older transformers with mechanical current protection, Type
BW reacts instantly to overload conditions. Therefore, Type
BW will react much faster to an overload than conventional transformers,
but power reset time will decrease as well.

| Type
BW and short circuits |
|
o protect against overheating and damage due to short circuits, Type
BW is equipped with an electronic current-sensing circuit breaker.
When a short circuit occurs, the green light will flash on and off
and power output will cease. This will also occur if the 5-amp current
limit is exceeded. The unit will reset automatically once the short
has been corrected,
In rare instances, BW/PowerHouse’s mechanical
circuit breaker may trip. To reset the circuit on BW/PowerHouse, push
the circuit breaker in.

To
prevent sudden train starts, always move the throttle to zero
before resetting the PowerHouse breaker. |
