If the digital pressure reading is flashing with one blip on your vacuubrand Water Pump, there may be overpressure at the pressure transducer, with pressure exceeding 1060 mbar. Release the pressure immediately due to the risk of bursting.
Why doesn't my VACUUBRAND Laboratory Equipment pump achieve ultimate vacuum?
If your VACUUBRAND pump isn't reaching its ultimate vacuum or usual pumping speed, check the centring ring at the small flange connection for correct positioning and inspect the pipeline and vacuum system for leaks. Ensure the controller setting is correct by selecting the ''Pump down'' function with the speed set to ''HI''. Use vacuum lines with a larger diameter and keep them as short as possible. If the pump has been exposed to condensate, allow it to run for a few minutes with atmospheric pressure at the inlet to purge. Clean and inspect the pump heads for deposits. Replace diaphragms and/or valves if they are damaged. Check process parameters for outgassing substances or vapor generation.
What to do if VACUUBRAND Laboratory Equipment pump does not start?
If your VACUUBRAND Laboratory Equipment pump doesn't start or stops immediately, and the warning triangle and pump symbol are flashing, it might be due to a few reasons. If the pump has been exposed to condensate, allow it to run for a few minutes at maximum speed with atmospheric pressure at the inlet. Check for overpressure in the outlet line by removing any blockage or opening the valve. If the motor is overloaded, allow it to cool down, identify, and eliminate the cause of failure, then manually reset it by switching off the pump or unplugging it.
Why does the display disappear on my VACUUBRAND Laboratory Equipment?
If the display on your VACUUBRAND Laboratory Equipment disappears, check the current draw of the connected devices to ensure there isn't too much load. Inspect connected valves for short circuits and replace them if necessary. Also, check the RS 232 plug and cable for any short circuits.
What causes incorrect pressure readings in VACUUBRAND Laboratory Equipment?
If the pressure reading on your VACUUBRAND Laboratory Equipment is incorrect, readjust the CVC 3000. If there's humidity in the measurement chamber, let the pressure transducer dry by pumping and readjust if necessary, also determine and eliminate the cause for humidity. If the pressure transducer is contaminated, refer to the section on cleaning the pressure transducer.
What to do if vacuubrand Water Pump stops and arrow down is flashing?
If your vacuubrand Water Pump stops during "Pump down" mode and the "arrow down" is flashing, it indicates that the pressure is below the preset minimum. Confirm by pressing the START/STOP key and adjust the minimum pressure value if necessary.
Why is the digital pressure reading flashing on my vacuubrand Water Pump?
If the digital pressure reading is flashing and the display shows "0.0" on your vacuubrand Water Pump, the pressure transducer may not be correctly adjusted under vacuum. Adjust the CVC 3000 correctly.
What to do if vacuubrand Water Pump stops and arrow up is flashing?
If your vacuubrand Water Pump stops during "Vac control" mode and the "arrow up" is flashing, it means the preset maximum pressure has been exceeded. Confirm by pressing the START/STOP key and adjust the maximum pressure value if necessary.
How to fix no display on vacuubrand Water Pump?
If there is no display on your vacuubrand Water Pump, consider the following: * Check if the mains plug is properly connected to the NT VARIO / VARIO-B pump and plug it in. * Ensure that the controller CVC 3000 or pump NT VARIO / VARIO-B is switched on. * Verify the VACUU • BUS cable is correctly plugged into the controller CVC 3000.
What to do if VACUUBRAND Laboratory Equipment venting valve does not respond?
If the venting valve does not respond and the valve symbol is displayed on your VACUUBRAND Laboratory Equipment, the venting valve might be contaminated. Clean the valve.
