STEP II - Establish communication between the TIU and a PS2 Engine
A. Place one PS2 equipped engine on a track hooked to the Fixed 1 output of the TIU.
B. Power up the transformer that is hooked to the Fixed input 1 of the TIU.
C. Press the READ button. - If the remote does not find the TIU go back to STEP I
D. Try to add the PS2 engine in to the remote by pressing the MENU button, then
selecting System, then Engine Setup, Add Engine, Add MTH Engine.
1. If the engine adds in to the remote that means that channel seems to be
working properly - do a track signal test to make sure.
2. If the engine does not add in to the remote:
a. Make sure that the engine is not already in the remotes engine list.
If the engine is already in the remote then select the engine from the
list and start it up - if the engine starts up that means that channel on
the TIU seems to be working ok - do a track signal test to make sure.
b. Make sure there is in fact power on the track by placing a lighted
car on the track by the engine or checking any lighted lock-ons that
may be hooked to that particular track.
-If there is no power to the track then check the wiring from the out
put of the TIU to the track. If that looks ok then you may open the
TIU and check for either a blown fuse in the TIU or a loose wire
connecting the PCB to one of the input/output terminals.
c. Make sure that the DCS signal is turned on to that track by pressing
the Menu button, then selecting System, then DCS Setup, then press
the S3 soft key it will say AON above it on the LCD. Try to add the
engine again. If the engine adds in to the remote that means that
channel is now working properly - do a track signal test to make sure.
d. Rule out the layout/wiring as being the problem. You can do that
by hooking up just a test track to the output of the channel and
placing one PS2 equipped engine on it. Power everything back up and
try to add the engine again.
1. If the engine adds on the test track that means the problem most likely lies
in the layout/wiring. Do a track signal test while the engine is on the test track -
you should have no less than a 10.
2. If the engine does not add on the test track or you have a poor track signal
strength then it is recommended to return the TIU for repair.
E. Test all other channels on the TIU to be sure they can communicate with a PS2
engine. Be sure to power up either Fixed 1 or AUX power when using Fixed 2, VAR 1,
or VAR 2. If you can not get any voltage out of one or both of the variable channels
then proceed to STEP III.
