Switch-On Behaviour At Initial Start-Up - Festo CMSX-C-U-F1 Series Manual

CMSX-...-C-U-F1-...

Switch-on behaviour at initial start-up

After the initial application of supply voltage, the positioner is in the following status:
– Operating mode: Automatic (Auto)
– Operating status: PID controller stopped (Stopped)
The positioner behaves as follows:
– The PID controller is inactive and does not react to setpoint specifications.
– The positioner reacts to control signals at the digital input D-IN.
– The display shows the initial position.
The setpoint position (SP) in the first line and the current valve position (VP) in the second line are
displayed in percent. Example (operating status PID controller stopped; valve position 0 % –
closed):
−−− 0.0 %
VP: 0.0 %
