PS 3.0 Enhancements

Here are some of the exciting changes incorporated into your new MTH Proto-

Sound 3.0 Locomotives. More advanced features such as Custom Speed Tables

and Advanced Consisting can be found in the DCC section of this manual.

Conventional (Analog) AC/DC Start-up/Shut-down

Your new MTH PS3.0-equipped locomotive no longer has batteries. It uses Super

Capacitors to hold the engine board alive for a short time when you shut off or

interrupt track power. Because of this, when you first apply track power to your

PS3.0-equipped O Gauge engine, you will notice the headlight comes on but

nothing else. This is perfectly normal. The capacitors are charging up during this

time. The wait time depends upon how long it’s been since you last applied power

to the engine. Typically it will take 1-15 seconds to fully charge. NOTE: The 1-15

second charging wait time ONLY applies to conventional AC track power.

Once the headlight shuts off, the engine will play its start-up sounds and all the

lights will come back on, simultaneously. Smoke too if you have it turned on.

The capacitors hold enough charge to play the full shut-down sounds. Also, the

capacitors allow you to operate your engine in conventional mode just like you

would any other conventionally-controlled engine. Finally, because there are no

batteries, you will notice there is no external

charge jack on the engine.

DCS/DCC Switch

Your MTH PS3.0-equipped engine has a

DCS/DCC selector switch (located on the

underside of the tender in steam engines). To

operate the engine in DCS mode, ensure the

switch is set to DCS. If you wish to run the

engine in DCC mode, ensure the switch is set to

DCC.

If you inadvertently leave the switch in DCC it won’t hurt anything, you just won’t

be able to communicate with your engine with your DCS system. Likewise, if you

leave the switch in DCS and try to operate the engine under DCC you may notice a

humming coming from your engine and you will likely notice that your DCC

system’s overload light will be on.

Programming Track (for DCC operation)

Your MTH PS3.0-equipped O Gauge engine can function on Programming Track

outputs from DCC systems. Most DCC systems can support the current

requirements of the engine as long as it’s not started up. If you plan on powering

up the MTH engine on your programming track, you may want to consider a DCC

Programming Track Booster.
