What to do if the Pfeiffer Vacuum Water Pump station will not start up?

If the Pfeiffer Vacuum Water Pump station won't start and none of the LEDs on the DCU are lit, it could be due to several reasons: * **Electrical supply interruption:** Check the supply lines to the pumping station, the 24 V DC output voltage on the 'DC out' connection of the integrated power supply, the plug-in contacts on the power supply, and the connection cable between the power supply, backing pump, and turbopump. * **Incorrect operating voltage:** Ensure you are using the correct operating voltage as specified on the rating plate. * **No operating voltage:** Apply the operating voltage. * **Defective electronic drive unit:** Replace the electronic drive unit according to the turbopump's operating instructions and inform Pfeiffer Vacuum Service.
