We know that the Setting is referring to the

since 9 is the MAXimum setting,
and Lewan states power was at this point
constantly switched on, then a setting of 9
is presumably a 100% duty cycle. (?)
Since the PLCs are programmable, we cannot
assume that a setting of 5 is 50% or 60%; it
could even be programmed to be 10% duty cycle.
So no useful calculations OR conclusions can be made during this ramp-up phase.
Lewan did report that at setting "5" the "ON" and "OFF" times were equal.
So taking the duty cycle as PLC/9 is about as good as we can guess.
