Hi all,
I am trying to improve the smoke output on a LGB Heidi 20272. It is factory fitted with decoder and sound. What I was planning on doing was to fit a relay to the existing smoke output in place of the existing 5v smoke generator. I would then use the relay contact to switch track voltage to a 24v smoke generator.
What I am struggling with is that the smoke output is modulated, I assume to reduce the voltage but cannot ascertain the CV to adjust the value. I have been unable to locate any information about the decoder on board. I have attached a picture of it. I have tried looking at it with JMRI. It reports as a Massoth Type 35. If I connect an LED across the smoke terminals (1K resistor) in series it turns on and off with F7. I am doing this using my NCE controller so the track voltage is low (13v)
I have looked at the output with a scope and I get a peak voltage of around 1.8V which will result in poor performance of the 5v generator so if I can solve this it might be that the 5v unit is OK.
Any assistance would be appreciated.
