reports in register 769 with the warning “Mechanical error, device blocked, manual
intervention or calibration”. The LED on the actuator cover blinks green, the LED
on the cable adapter is red.
Upon return to automatic mode, the actuator synchronizes to stroke position 0%.
After the synchronization, the actuator follows the pending setpoint, the LED on the
cover changes to continuous green and, on the cable adapter, blinking green
(communication active). The warning in register 769 is reset.
