SETPOINT
2 boolean array - -
1) To adjust range refer to chapter: «Range of pressure and position values»
2) Valves with isolation functionality (e.g. 650): “Valve is closed” means valve is sealed / isolated. Valves without
isolation functionality (e.g. 612): “Valve is closed” means valve is at the minimum control range position.
3) Valve is moved to minimum control range position but is not isolated/sealed if the valve has a isolation / sealing
functionality (e.g. series 650).
