Another TIU not responding

Try moving the track wires AND transformer wires to another set of TIU red/black terminals.  There are four mostly independent channels in TIU so if one cfhannel is down the remainders should (??) operate OK.  Try another DCS engine if available to verify it operates.  There are 20 amp fuses inside the TIU of which that channel just might have popped.

If still dead and verified that there is 18VAC to the rails, then you may have fried the engine board(s) and now joined the Dead Engine Society

Thanks rrman,

Fixed port 1 works fine.  All of my other PS2 engines work fine through Fixed port 1 and conventional on Fixed port 2.

You lost the DCS signal on FIX 2, that's why the engine starts up in conventional.  It isn't seeing the DCS signal.  That can be repaired.  You also have VAR 1 and 2 you can use as fixed.  Definitely need fuses with PW ZW.  G

JD,

   Purchase some Scott 10 Amp breakers and put them between your transformer and your TIU before you damage your TIU.  The 10 amp breakers are easy to reset if something happens to pop them.  You simply put the transformer back to zero and

remove the problem from the tracks, and push the breaker back down to reset the breaker, you are then back in business with no damage done to your TIU or your engines.  If you keep using your TIU and the old ZW without the 10 Amp breakers or fuses, you are going to sooner or later severely damage your TIU. 

Quit running your trains till you safe guard your DCS TIU.

Thanks guys!

I've definitely learned my lesson and will be purchasing some breakers to safeguard my TIU.

Thanks Mort!
