Need Advice/Problem Fixed

Depends on what you are running? I'm no expert, but will try to help a bit here.

Unless you use an aux power supply for your TIU, you need power on Fixed 1 to also power your TIU.

Variable inputs are usually for running conventional, Fixed are for DCS operation (command control).

There are other ways to do all this, but I'll quit here in order to not muddy the waters further.

Someone else will probably be along to provide better explanations, but that's the basics.

rtr12 has it right.

There are 2 ways to power the TIU.

One is through the aux power jack.

The second is the supply to fixed input 1.

If you are only using one channel, the latter is just fine.

If you are using more than 1 channel, the aux power jack is highly recommended.

This is all in Barry's book BTW. Well worth buying IMO.

You can daisy chain the Fixed 1 input from any other input to power the TIU.

You do not have to use Fixed 1 out unless you want too. Aux Power frees up the jumpers. Aux power also avoids Control loss if Channel Fixed 1 pops a breaker and the other channels stay powered up.

For avoiding power overload in a transformer I would alternate blocks from Channel and brick to another channel and brick.

WARNING: This works great in Command mode, not so good in conventional. Keeping the power on both tracks (alternating blocks) set the same is a lesson in frustration.

Now one way to avoid this is to run conventional by powering the track direct from the transformer and using DCS in passive mode. This does not allow you to remotely control speed tho.

It all comes to this: Do you need conventional  control on the track or are you going All command control?

Hello all,

All is well!  THANK YOU to everyone who replied. I put the Z4000 into the Fixed Inputs of the TIU. Then from the fixed outputs of the TIU to the designated terminal blocks for each track.
