Why is there no digital pressure reading on my vacuubrand CVC 3000?
- AAllen WrightSep 7, 2025
If there is no digital pressure reading on your vacuubrand Controller, it may indicate a defective pressure transducer.
Why is there no digital pressure reading on my vacuubrand CVC 3000?
If there is no digital pressure reading on your vacuubrand Controller, it may indicate a defective pressure transducer.
Why Controller does not react when pressing keys (except ON/OFF), PC symbol is displayed?
If the vacuubrand Controller does not react when pressing keys (except ON/OFF) and the PC symbol is displayed, it means the controller is in remote operation. You can either control the controller via the interface or switch off remote operation.
Why function is not displayed, no menu on vacuubrand CVC 3000 Controller?
If the function is not displayed and there is no menu on your vacuubrand Controller, it indicates that no controllable device (valve, VMS, NT VARIO/VARIO-B pump) is connected. To resolve this, connect the necessary devices or use the controller as a measuring device.
What does it mean if there is no digital pressure reading, warning triangle is flashing, five or seven blips on vacuubrand Controller?
If the warning triangle is flashing with five or seven blips and there's no digital pressure reading on your vacuubrand Controller: * For five blips: the external sensor might be defective or removed. Plug in the sensor, use a new one, or reconfigure without the sensor. * For seven blips: it could indicate that the internal sensor is defective.
What to do if warning triangle and pump symbol are flashing with six blips on vacuubrand CVC 3000?
If the warning triangle and pump symbol are flashing, accompanied by six blips, and you're using an NT VARIO / VARIO-B pump with a VMS, try disconnecting the VMS and starting the vacuubrand controller. Alternatively, there may be a fault with the NT VARIO / VARIO-B pump or the VMS itself, so check the pump and/or VMS or reconfigure. Also, ensure the connecting cables from the pump or VMS are securely attached.
What to do if venting valve does not react, valve symbol is displayed on vacuubrand CVC 3000?
If the venting valve on your vacuubrand Controller does not react, but the valve symbol is displayed, it may be contaminated. Try cleaning the valve to resolve this issue.
Why internal venting valve does not react, valve symbol is not displayed on vacuubrand CVC 3000 Controller?
If the internal venting valve does not react and the valve symbol is not displayed on your vacuubrand Controller, it could be because an external pressure transducer is connected and active. To fix this, select the internal pressure transducer or connect an external venting valve.
What to do if function “Pump down” control stops, arrow down is flashing on vacuubrand Controller?
If the function "Pump down" stops and the arrow down is flashing on your vacuubrand Controller, it indicates that the pressure is below the preselected minimum pressure. You can confirm by pressing START/STOP and adapt the pressure value if necessary.
How to solve function “Vac control” stops, arrow up is flashing on vacuubrand CVC 3000 Controller?
If the function "Vac control" stops and the arrow up is flashing on the vacuubrand Controller, it means the preselected maximum pressure has been exceeded. To resolve this, confirm by pressing START/STOP and adapt the pressure value if necessary.
Why is the clocks symbol flashing and control stopped on my vacuubrand Controller?
If the clocks symbol is flashing and the control is stopped on your vacuubrand Controller, it means the preselected process time has passed. To proceed, confirm by pressing the START/STOP button.
