Control Mode
The Control Mode represents the state machine of the valve. Writing to Control Mode requests a
change in the state while reading Control Mode returns the actual state of the state machine.
Init
State after power up. Remains if Homing is not started or no Exception occurs
Homing
The valve performs the homing procedure to initialize the position.
Refer to chapter Homing
Position
The valve moves to the desired Target Position.
Close
The valve closes.
Open
The valve opens.
Pressure Control
The valve controls to the desired Target Pressure.
Refer to chapter Pressure Control
Hold
The valve remains in the actual position.
Usage during Pressure Control:
Reduce valve reaction during plasma ignition.
Stopping the valve movement to evaluate the stability of the sensor, flow meter, …
Note: Change from Control Mode Close to Hold is not possible
Learn
The valve performs the system learn. Necessary for Adaptive Pressure Control.
Refer to chapter Pressure Control/Adaptive Algorithm/Learn
Interlock Open
The valve opens and locks due to the actuation of a digital input. Release behavior:
Control Mode changes to Open or to Init if no Homing was performed yet.
Refer to Chapter Power IO
Interlock Close
The valve closes and locks due to the actuation of a digital input. Release behavior:
Control Mode changes to Close or to Init if no Homing was performed yet.
Refer to Chapter Power IO
Power Failure
Power loss occurred. The valve opens or closes (Only with optional Power Failure Option)
Closing or opening behavior depends on set Power Failure.Functionality
Refer to chapter Power Failure
Safety
The motor of the valve is powerless due to a digital input.
Release behavior: Control Mode changes to Init
Refer to chapter xxx
Error
The valve is in an error state, no movement possible.
