Manual Override
The actuators can be driven manually to any position between 0 and 1 with a 3 mm hex key.
The actuator will maintain its position until power is provided or restored. A control signal
from the controller, however, will take priority over any manual position.
NOTES:
• Do not perform a manual override while the power supply is connected: The
actuator will not track properly when the control signal is applied. A short power-
off/power-on sequence is recommended to recalibrate the actuator.
• To hold the actuator in the manually set position, the connecting cable must be
unplugged.
