Controller operations
Type BW functions
Y
our Type BW provides a total output of
five amps. The track (variable) output
will deliver five amps to the track when no
load is connected to the accessory (fixed)
"U" terminals. The accessory terminals also
provide a maximum output of five amps,
but the total output cannot exceed five
amps. For example, if your track output is
three amps, you have two 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
12-16VAC.
The 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
Type BW and short circuits
T
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, the BW/PowerHouse's
results. It may be necessary to power up
slowly at this load to prevent surge current
from tripping the Type BW's protection
circuit.
The 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,
the Type BW reacts instantly to
overload conditions. Therefore,
the Type BW will react much
faster to an overload than
conventional transformers, but
power reset time will decrease as
well.
mechanical circuit breaker may trip. To
reset the circuit on the BW/PowerHouse,
turn off the PowerHouse, then push the
circuit breaker in (see Figure 5 on page 8).
To prevent sudden train starts,
Note!
always move the throttle to zero
before resetting the PowerHouse
breaker.
