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.
0 |
Init |
State after power up. Remains if Homing is not started (see Homing.Start Condition) or no Exception occurs |
1 |
Homing |
The valve performs the homing procedure to initialize the position. Start condition: depends on set Homing.Start Condition Behavior at end: depends on set Homing.End Control Mode Refer to chapter Homing |
2 |
Position |
The valve moves to the desired Target Position. |
3 |
Close |
The valve closes. |
4 |
Open |
The valve opens. |
5 |
Pressure Control |
The valve controls to the desired Target Pressure. Refer to chapter Pressure Control |
6 |
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, … Change from Control Mode 3 Close to 6 Hold is not possible |
7 |
Learn |
The valve performs the system learn. Necessary for Adaptive Pressure Control Refer to chaper Learn |
8 |
Interlock Open |
The valve opens and locks due to the actuation of a digital input. Release behaviour: Control Mode changes to 4 Open or to 1 Init if no Homing was performed yet. Refer to Power connector IO |
9 |
Interlock Close |
The valve closes and locks due to the actuation of a digital input. Release behaviour: Control Mode changes to 3 Close or to 1 Init if no Homing was performed yet. Refer to Power connector IO |
12 |
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 Power Failure Option |
13 |
Safety |
The motor of the valve is powerless due to a digital input. Release behavior: Control Mode changes to 1 Init |
14 |
Error |
The valve is in an error state, no movement possible. Recovery via Services.Restart Controller. Set Services.Error Recovery TRUE for recovery without restart (no communication lost). Refer to chapter Trouble Shooting |
