All fail-safe MEP-42xx/45xx/49xx models offer
selectable clockwise or counterclockwise direction.
(Proportional and tri-state models also offer the op-
tion to turn the fail-safe off—usually temporarily for
test purposes.) Using a small, flat-bade screwdriver,
adjust the switch dial to the desired CW/OFF/CCW
option.
