I am installing a P5 into an engine with battery and airwire decoder. I was hooking everything on a bench for a test and the chuff was set to work automatically. I plan to use the reed switches to trigger with magnets, using C2 pins 3 and 4 for the reed switch per the manual had no effect, I tried intermittently touching the wires together to no effect. The P5 was programmed at the ECLSTS for a K-27. How do I get the auto chuff switched to manual triggering? The manual does not cover this point that I can find. Thanks.

Hi Jon.
You have to get into the program and change the function allocation.
For that you will need the Phoenix programmer.
Pins 3 & 4 are trigger # 1. Pins 1 & 2 are trigger # 2. Leave whichever one you wish to use set to trigger "low".

Whoever programmed the P5 may have forgotten to turn off the function -"use DCC for speed" It is usually on by default. if on, it will disable the reed sw input This function is in the DCC section of the screens.

You learn something every day.

So, I take it there are actually three ways to get the chuff.

1. Manual.
2. Auto.
3. DCC.

Tony, I think the 2 options are autochuff or triggered (by contacts)..... dcc is not a different mode for the chuff. In your post Tony, 2 & 3 are the same.
