General SystemInformation

The generator performs three functions in the EFX. First, by controlling the amount of electrical load applied to

internal battery. Lastly, one ofthe generators six phase outputwindings is monitored to determinewhen the

unit is in use and when it is idle. This system also determines the stride rate by determining the operating speed

(output frequency) of themonitored generatorwinding.

Warning and Caution Statements and General Safety Guidelines

Warning statements indicate a particularly dangerous activity. Warning statements you will find in this manual include:

If the EFX hasbeen in recent use, the load resistors and load resistor mounting bracket may be extremelyhot.

Because thisis a self powered unit, it will either be necessary to either equip theunit with the optional external

power supply orhave an assistant pedal on the unitwhile voltagemeasurementsare being taken. Because of the

danger of working onthe unit while it is in motion using the optional external power supply is strongly

recommended.

When the unit isused, stairarms are in motion; the generator will operate and produce potentially hazardous

voltages even when the battery is disconnected.

To remove power from the EFX, the optional external power supply (whenequipped) mustbe disconnected

from the wall outlet and the red (positive) lead must be disconnected from the battery. Always ensure that the

EFX external power supply is unplugged from the wall outlet and thered (positive) lead is removed from the

battery when you inspect or adjust theEFX, or whenyou isolate, remove, or replace anEFX component.

Removing the covers exposes high voltage components and potentially dangerousmachinery. Exercise extreme

caution when you perform maintenance procedureswith the cover(s) removed.

During service operations you will bevery close to moving machinery and voltagebearing components. When

you perform maintenance procedures with the covers removed, remove jewelry (especially from earsand neck),

tie up long hair, removeneck ties, and do notwear loose clothing.

Exercise caution when touching any wire or electrical component during EFX operation.
