The Wakespeed WS100/12 provides
four levels of field output control to allow
the user to de-rate the alternator to limit
engine horsepower load.
Controlled by the (RED) color-coded
knob labeled Field Limit to the left of
center at the top of the regulator, the
field output can be adjusted by turning
thumbscrew clockwise or counter-
clockwise.
Output levels are broken down by
percentages of maximum field output
provided by the regulator. Limits will be
indicated as follows:
1. 100% Field — Indicated by no
RED lights on the regulator, next to
codes indicated by A, B, or C on the
regulator’s label.
2. 90% Field — Indicated by the RED light illuminated by the letter A
on the regulator’s label.
3. 75% Field — Indicated by the RED light illuminated by the letter B
on the regulator’s label.
4. 50% Field — Indicated by the RED light illuminated by the letter C
on the regulator’s label.
NOTE: Adjustments to the Field Limit can be made “on the fly”
and will immediately result in a decrease or increase to the value
selected.
Wakespeed recommends setting the field limit at 90% to provide
protection against saturation alternator output.
