    ► Make sure that the gas mode is set correctly by [P:027] in the electronic drive unit. ► Consult Pfeiffer Vacuum before you use gases with higher molecular masses (> 80). High gas throughput and high rotation speed lead to strong friction heating of the rotor. To avoid over- heating, power to rotation speed characteristics are implemented in the electronic drive unit.

    3. Check the set rotation speed (parameter [P:308] or [P:397]). 7.2.6 Standby Pfeiffer Vacuum recommends standby mode for the turbopump during process and production stops. When standby mode is active, the electronic drive unit reduces the rotation speed of the turbo pump.

  • Page 40: Backing Pump Operating Modes

    Fluctuations in the power consumption of idling turbopumps and varying fore-vac- uum pressures of the backing pumps require individual settings of the interval operation. Pfeiffer Vacuum recommends interval operation between 5 and 10 hPa. A pressure gauge and a dosing valve are required to set the switching thresholds.

    2. Use this signal for the control of a fore-vacuum safety valve. 7.2.9 Backing pump standby mode In case you are using a Pfeiffer Vacuum backing pump with rotation speed control, this can be used in standby mode by configuring the digital output [P:019] or [P:024]. The power consumption of the turbo- pump has a direct influence on the rotation speed of the backing pump.

  • Page 42: Operation Via "Remote" Connection

    The digital inputs at the "remote" connection are used to switch various electronic drive unit functions. As a factory default, inputs DI1 – DI2 have that can be configured with the Pfeiffer Vacuum parameter set via Profibus or the RS-485 interface.
