4.13.4 Manual adjustment

The actuator's internal stroke position measurement is inactive during manual
adjustment.
The position feedback changes to 0% once the manual adjuster is pressed and
remains on the value during manual adjustment. The actuator detects manual
action based on the deviation between the setpoint and the stroke position and
after 10 seconds reports in register 769 with the warning "Mechanical error, device
blocked, manual intervention or calibration". The actuator LED blinks green, the
cable adapter LED is red.
Upon return to automatic mode, the actuator synchronizes to stroke position 0%.
After the synchronization, the actuator follows the pending setpoint, the actuator
LED changes to continuous green and the cable adapter LED blinks green
(communication active). The warning in register 769 is reset.
