Rail King GG-1 ELECTRIC ENGINE Operator's Manual - Basic Operation
Basic Operation
DC Operation
Features such as the bell, horn, coil coupler etc; can not be accessed when using a
DC type power supply.
Apply power to the engine by increasing the throttle so that the track voltage is
approximately 8 volts. Att his point the engine will power up, but will not move.
Slowly increase the throttle and the engine will begin to move.
Direction changes can be made by switching the direction button without adjusting
the throttle. When the direction switch is changed the engine will slow down, stop,
then gradually speed up in the opposite direction to the previous throttle setting.
The throttle can be changed during this operation to adjust the speed. Or the
throttle can be used to reduce the track voltage until the engine stops, then change
the direction switch and increase throttle to the desired speed.
DCS Operation
The engine can be operated with the DCS System using either AC or DC input
voltage.
All features and functions are available in the DCS mode with either input voltage.
DCS Polarity Switch
When operating in the DCS mode the engine must be oriented so that the rail with
the DC + or the AC High is making contact with the wheel on the left side of the
locomotive.
Since this would limit the engine facing one direction all of the time, MTH has
incorporated a DCS Polarity switch. As a result the engine does not have to always
face the same direction based on the track wiring.
Make sure that the DCS Polarity switch is in the correct position before attempting
to add the engine to the DCS Remote.
If the DC + or the AC High is wired to the rails on the left side of the engine, the
DCS Polarity switch should be in the forward position.
If the DC + or the AC High is wired to the rails on the right side of the engine,
the DCS Polarity switch should be in the position towards the rear of the engine.
