Page 34: Operation
Operation 7 Operation 7.1 Configuring the connections with the Pfeiffer Vacuum parameter set The electronic drive unit is pre-configured with the factory default basic functions and is ready for opera- tion. For individual requirements, you can configure most connections for the electronic drive unit with the parameter set. -
Page 35: Operating Modes
► 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. -
Page 36: Set Value Power Consumption
Operation 7.2.2 Set value power consumption Set parameter [P:708] When setting the specified power consumption below 100%, the run-up time is extended. 1. Set the parameter [P:708] to the required value in %. 2. Where necessary, adjust the parameter [P:700] RUTimeSVal to avoid error messages when starting up. -

Page 38: Standby
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 39: Tbl. 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. -
Page 40: Backing Pump Standby Mode
Operation 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. -
