Manual Override
For manual positioning, turn the manual override knob in the
center of the position indicator. See Figure 9. Turn the wrench
clockwise to extend the actuator spindle. The actuator will
maintain its position until power is provided or restored.
NOTE: For SSB61U
If an override is performed while the power supply is
connected, the actuator will not track accurately when the
control signal is applied. A short power off/power on sequence
is recommended to recalibrate the actuator.
