Testing The Proto-Sound 3.0 Upgrade
Installation
- Place the engine chassis on a test section of a track.
- Apply 12 volts of power (in conventional mode) to the engine. If you have a
Z4000 look at the current display. The engine should not draw more than 1.5
amps. If the engine draws more than 1.5 amps, shut down power to the engine
immediately and check your wiring for any pinched or cut wires. Turn the
smoke unit switch off and power up again in conventional mode. The engine
without the smoke unit on should not draw more than 1.0 amp. Troubleshoot
any problem in the smoke unit or wire harness accordingly.
- Check the smoke unit for operation. If no smoke is coming out or you can't
feel the fan blowing air out, the gray/green wires connected to the fan motor
may be reversed.
- Press the direction button and verify the locomotive moves in the forward
direction. If the two motors in a twin-motored unit appear to be fighting each
other, reverse the white and yellow motor wires on one motor. If the engine
starts in reverse, reverse the yellow and white wires to both motors. If the
engine does not move, the engine may be locked in neutral, see lock/unlock
command on page 32.
- Press the whistle button and verify the horn test sound. The sound is not a
normal horn but a test tone.
- Press the bell button and verify the bell test sound. The sound is not a normal
bell but a test tone.
- Fire the coupler using the combination signal in conventional mode or the
digital signal with the DCS remote. Note: The engine must have a rear Proto-
Coupler connected or a 4.7k-ohm resistor (MTH P/N AI-0000062) installed
in place of the rear Proto-Coupler for proper operation of the front Proto-
Coupler and so that the PS3 Board is not damaged.
- Press the direction button and verify the engine stops.
- Press the direction button again and verify the engine moves in reverse
direction and that the headlight and back-up lights work properly.
- Install the body on the engine chassis being very careful not to pinch any wires
in the process and repeat the tests above.
