Уже нашел ответы на один вопрос в описании блока CYCLONE 360 (аналог Eikon EMS-250)
Follow Through-This displays the amount of skipping that occurs when your machine is swinging up and down.
When the machine is off the contact screw and front spring are touching. Once power is applied to your
machine the coils are magnetically charged, Thus forcing the armature bar to swing down. The swing
down motion then breaks the connection with the contact screw and front spring. The back spring then
forces the armature bar to return back to its original position. If there is any skipping the CYCLONE 360
will display the number of times the skipping occurs. You want to get it as close to ZERO as possible to
guarantee a clean follow through. Many factors that may cause this problem would be contact screw
angle and gap. Any minor adjustments can alter your follow through.
Duty Cycle-This displays the relationship between the contact opening time and contact closing time per swing.
The Cyclone 360 can tell you the contact closed time per swing. If the contact point is closed 60% and
opened 40% per swing, the LCD will show the closed time of 60%. This helps explain the force of the back
spring in relation to the hardness of the front spring. If the back spring is putting a lot of force on the front
spring, then you will get a higher Duty per swing.
А это из описания к канадскому блоку Eikon EMS 200, вероятно, с которого и был скопирован CYCLONE 360.

Пояснение:
duty cycle - это скважность, отношение длительности импульса к периоду следования импульсов. Другое название - коэффициент заполнения.
Как я предполагаю, фактически изменяя скважность (настройками машины) мы меняем ее эффективную мощность.
И разъемы там кажись, моно-джеки 6.3 установлены.
