Important
After startup, it is recommended that you use the control system to operate the actuator and
check the behavior as well as signaling of the actuator.
To place the actuator in automatic mode after startup, a 24 V DC signal at the digital input 1
must be present for actuators with active digital input functions (default setting).
If the digital function is switched off, the actuator switches to automatic mode immediately after
completing the adjustment process.
