Linear actuator, left-hand or direct mounting
Adaptation of the mechanical stops only Autostart recommended for standard application
Enh. Autostart. Optimized control behaviour compared to Standard Autostart
Enh. Autostart. Damped control behaviour for e.g. smaller actuators Enh. Autostart. Undamped control behaviour for e.g. larger actuators
Action of Positioner:

Valve opens with increasing setpoint value Valve closes with increasing setpoint value
Action of Feedback Unit:

Increasing Current with increasing valve position Decreasing Current with increasing valve position
No accessories mounted Booster mounted
