Section One - Things You Should Know

Right, Left, Front, and Back Conventions
In this manual, right, left, front, and back are from the perspective of a user standing on the EFX,
facing the display enclosure.
General System Information
• The generator performs three functions in the EFX. First, by controlling the amount of
electrical load applied to the generator, the user's pedalling resistance is controlled.
Second, the generator is used to charge the EFX's internal battery. Lastly, one of the
generators three phase output windings is monitored to determine when 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 the monitored generator winding.
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 has been in recent use, the load resistors and load resistor mounting bracket may
be extremely hot.
• Because this is a self powered unit, it will either be necessary to either equip the unit with
the optional external power supply or have an assistant pedal on the unit while voltage
measurements are being taken. Because of the danger of working on the unit while it is in
motion using the optional external power supply is strongly recommended.
• When the unit is used, 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 (when equipped) must
be 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 the red (positive) lead is removed from the battery when you inspect or adjust the
EFX, or when you isolate, remove, or replace an EFX component.
• Removing the covers exposes high voltage components and potentially dangerous
machinery. Exercise extreme caution when you perform maintenance procedures with the
cover(s) removed.
• During service operations you will be very close to moving machinery and voltage bearing
components. When you perform maintenance procedures with the covers removed, remove
jewelry (especially from ears and neck), tie up long hair, remove neck ties, and do not wear
loose clothing.
