DCS conventional mode back to command mode: HOW

Leave wires on variable circuits.  Dial track voltage to about 17-18 volts.  Press eng button, select the loco you want, and press start up.

 

 

 My understanding is that you MUST wire through a variable channel for conventional control.

Only if you want to use remote to control conventional.  You can use fixed and run conventionl using the Z4000 handles.  When you want to run command, move levers to 17-18 volts, press ENG and startup, and you're running command with the remote.

I feed the transformer  wires to the center contacts of a DPDT switch.  Throw the switch one way and direct the wires to your TIU input.  Throw it the other way and you have conventional control.  I have another switch to keep the TIU from getting back fed when I (hardly ever) run something in conventional.  Figure it out and do the job one time.  These switches were put in when DCS came out.  The 4 switches cover two Z4K transformers to the 4 TIU channels.

 

 

Thank you.  I did exactly ad u suggested.  The command engines can't be found.  I turned everything on and off.  I reset.  I can't get command to work from variable 1.  I can't use handles.  My layout is basement sized.  I need walk around capability.

What did you reset?  If you reset the remote, you wiped out the data, which includes locos.  To me, resetting a remote is to be avoided, especially if you have not backed up the data to a computer.

 

Are you powering the TIU itself through the AUX port with either a wall wart or a brick, or by applying power to fixed 1.

If you wired to vari 1, press menu, system, DCS setup. FXD soft key will switch from variable to fixed voltage and back.

This can be done to variable 2 also.

RJR has it  right..... I'm not sure where you're at now but it seems var 1 is not putting out a dcs signal or your layout needs some wiring attention.

 

Anyway test VAR 1 in command mode with a short test  track... Set the channel to fxd and do a track signal test with a know good engine.   TIU must also be power up with power to fixed 1 or an aux power supply.

 

You do another thread with the same issues??         

 

 

 

 

Yes I do have another thread.  The explanation is simple.  I'm losing my marbles and have way too much going on!  Sorry.  I just realized very early this morning I had done that.  Chalk it up to old age.  Am I the only one who emails or texts himself messages so not to forget?

TR for conventional.  Scroll up the voltage high and then select ENG for command. You need a good track signal for command.  hang in there, you'll get it solved.
