I have a Z-500 transformer through a TIU varialble channel 1
Question: with the Z-500 set to max when ramping up with the thumb wheel the voltage jumps to 5V on one of 3 TIU I have. I have reset the remote with no change, how do you reset below 5V?
Problem: when operating a Lionel Polar Express the air whistle operates constantly, is there a fix for this?
Sincerely,
Phil

Phil,

You cannot.
Barry,
Thanks for the reply interesting my other 2 TIU's start below 5V, I did see in your manual where you said for every click of the thumb wheel it adds .5 V above 5V, but couldn't understand why the other TIU's act different.
Can you offer any fix for the constant whistle problem?
Phil

Actually, that's a bug in DCS that sometimes occurred after a software upgrade. As I recall, if you use the soft keys to set the starting track voltage to 5 volts or greater, you'll never be able to set it to below 5 volts again.

Are you using the Z-Controller with the Z750 brick? If so, that's most likely causing the problem. Just use a barrel jack adapter to connect the brick directly to the variable channel's input.
The issue is that both the Z-Controller and the TIU variable channels chop the sine wave to lower voltage, and some engines don't like it when that is done twice.
Yes I am using the Z-500 with the controller I will order the adapter, thanks for the help.
