DO NOT OVERTIGHTEN SCREW !!

No other screws are necessary, as
the cord will keep the unit from
rotating. The PU-E gives a high
signal when the North Pole in the
magnet crosses the hall-effect
transistor. The signal is switched off
when the South Pole crosses the
hall-effect transistor. The result is a
square wave whose frequency is
proportional to the speed of the
shaft that the PU-E is mounted on.
The number of North/South Pole
pairs directly affects the output.

Note:

If installing the unit on a motor
purchased from Dart, the motor
shaft is already drilled and tapped.
If the motor is fan-cooled (TENV),
remove the plug in the center of
the fan guard before installing the
pickup. Otherwise, damage to the
pickup may occur.
