>> Stationary and moving are relative to the low, medium and high setting.
A bit more information:
Stationary is called "idle" - and is *unaffected* by the setting of L, M, or H. There are 4 levels (+ off) in the smoke system. Idle, L, M, H. Idle is entered after no motion is detected for a period of time. L, M, or H, enter into play as soon as motion is detected.
For example, one can move from idle to M, (or L or H) upon motion. Idle is a fixed level, in that only OFF can change the idle setting. Idle is where smoke units are "boosted" to get up to temp quickly on initial startup.
Additionally, the track voltage is monitored, and the level setting is adjusted to maintain smoke within the capability of the servo for the smoke unit. On steamers, the smoke level is adjusted based on chuff rate; time between fan pulses at slow speeds tend to overheat the element; so the temp is adjusted down at slow speeds.
This is the basic smoke unit operation that has been used for many years in Legacy to try and keep the wicking from charring and the smoke even.
