Page 6: Safety
● Power supply: The turbopump power supply must apply to the requirements of dou- ble insulation between mains input voltage and operating voltage according to the reg- ulations of IEC 61010 and IEC 60950. Therefore Pfeiffer Vacuum recommends to use exclusively original-power packs and -accessories. Only in this case Pfeiffer Vacuum is able to guarantee the compliance of the European and North American guidelines. -

Ensure the gas mode is correctly set. Contact Pfeiffer Vacuum before using gases with a greater molecular mass (> 80). ● Gas mode "0" for gases with the molecular mass >39, e.g. argon. ● Gas mode "1" for gases with the molecular mass 39. -
Page 34: Set Value Power Consumption
The Pfeiffer Vacuum parameter set To avoid rotation speed fluctuations, Pfeiffer Vacuum recommends setting a some- what lower frequency in rotation speed setting mode. 7.4.4 Set value power consumption Adjust the parameter [P:708] to the desired value in %. -
Page 35: Rotation Speed Setting Mode
The Pfeiffer Vacuum parameter set When the pumping station [P:010] is switched on, the rotation speed switchpoint 1 is the signal generator. When the pumping station is switched off, signal output and status que- ry are based on the rotation speed switchpoint 2. The signal output is governed by the hysteresis between the two switchpoints. -
Page 36: Standby
Pfeiffer Vacuum recommends the intermittend mode between 5 and 10 hPa. A pressure gauge and a dosing valve are required to set the switching thresholds. -
