Why does the display disappear on my vacuubrand CVC 3000 Controller?
If the display disappears on your vacuubrand Controller, it could be due to too much load connected, such as valves. Check the current draw of the connected devices like pumps and valves. It might also be due to a short circuit at connected valves, so check the valves. Another cause may be a short circuit at the RS232 plug, so check the plug and cable.
What does it mean when digital pressure reading is flashing, one blip on vacuubrand Controller?
If the digital pressure reading is flashing with one blip on your vacuubrand Controller, it indicates overpressure at the pressure transducer, meaning the pressure is greater than 1060 mbar. You should release the pressure immediately due to the risk of bursting.
What to do if digital pressure reading is flashing and '0.0' is displayed on vacuubrand Controller?
If the digital pressure reading is flashing and '0.0' is displayed on your vacuubrand Controller, it means the pressure transducer was not correctly adjusted under vacuum. To fix this, adjust the pressure transducer correctly.
Why is the warning triangle and coolant valve symbol flashing with four blips on vacuubrand Controller?
If the warning triangle and coolant valve symbol are flashing, accompanied by four blips, it might indicate that the coolant valve is either removed or defective. To resolve this, check the connection cable of the valve, try using a new valve, or reconfigure the vacuubrand Controller without the valve.
What does it mean when the warning triangle and valve symbol are flashing with three blips on vacuubrand Controller?
If the warning triangle and valve symbol are flashing, accompanied by three blips, and you have an NT VARIO / VARIO-B pump and in-line valve connected, disconnect the in-line valve and switch the vacuubrand controller off and on. Alternatively, if the in-line valve is removed or defective, check the valve's connection cable, use a new valve, or reconfigure without the valve.
How to fix no display on vacuubrand CVC 3000?
