Loss of voltage through the TIU

I had to look up what a 50-1014 was, could have just said terminal block

, I have input into all 4 ports on the TIU but only outputs on 3 of the 4. The #1 variable port does not have an output as I'm awaiting the arrival of a new 50-1014.

Did you use the remote and change the variable outputs to fixed or turn them all the way up to 22??

Just some notes about that- but a huge one is, the voltage displayed on the remote or DCS app (if you ever added a WIU and tablet) does NOT measure voltage, it's simply a range of how "ON" the output is assuming a known input voltage. Again, lot's of people will say the voltage doesn't match what is displayed- the fact is, it really should not be labeled voltage because it's not being measured.

It's possible that you have a damaged variable output, but I would do the basics first and ensure it's in the mode you expect and fully turned on as that could easily explain why.

This sounds like the variable on the TIU is not set at 22v/set to fixed.

Variable # 1 can still be measured without a distribution block on the end of it. Just run a pair of suitable cables from it and check the output. If it's at 0 or another lower voltage, make sure it's set to fixed/wide open, too.

You never say what voltage you're getting through the fixed channels. You mention them repeatedly but not what their final measurement is at the terminal block. If they're fine, the highest likelihood is that the TIU just hasn't had those channels set. That's why they're "variable"

Thanks for the advice. I'll check the settings on the variable outputs, as I have not done that. My fixed match the Z4k output, 10 & 14 volts. Hopefully, it's just that my variables aren't set.

You can go into DCS Setup under the SYSTEM menu and set the variable channels to fixed mode, that way they output full input voltage.

Thank you, John! Everything appears to be functioning normally now. Hopefully, that will continue as I lay additional track.

We love the simple ones that don't cost anything.
