Operating TMCC-equipped locomotives with the PowerMaster
W
hen operating Command-equipped locomotives with the PowerMaster, the PowerMaster
serves as a circuit breaker and a remote power switch. In this mode the track power
is either off or full on at the maximum output. The conventional bell, whistle, direction
and other key activated functions of the LEGACY PowerMaster are disabled. The speed of the
locomotive and all other locomotive features are controlled by addressing the locomotive
directly.
1. Set the COMMAND/CONVENTIONAL switch to COMMAND.
2. Press TR or ENG and enter the unique ID number for the PowerMaster.
3. Press BOOST to set the track power to full on
4. Press AUX1, 0 to turn off track power.
You may choose to limit the top speed of your locomotives by setting the maximum output
voltage available from the LEGACY PowerMaster. To set a voltage limit:
1. Press the SET button on the CAB controller. The output voltage will drop to 0 and the
green indicator will flash.
2. Use the THROTTLE knob on the CAB controller to set the outpt to the desired voltage.
3. Press the SET button again to lock in the voltage limit setting. The green indicator will
stop flashing and come on to show that the setting has been saved.
The voltage limit will be remembered even if the power to the PowerMaster is turned
off.
The voltage limit setting only applies when the Command/Conventional switch is
the CMD position. It will not affect the maximum output voltage and cannot be set
if the switch is in the CONV position.
Setting the voltage limit too low may result in the undesirable operation of some
locomotive functions (e.g., coil couplers, smoke units, sounds, etc.).
To clear the voltage limit setting:
1. Press the SET button twice without moving the Throttle knob. This will clear any previusly
set limits and allow the output of the LEGACY PowerMaster to go to the maximum
available voltage.
