The gas ballast system of the scroll pump is suitable for being connected to a gas external supply. Cou- plings for the G 1/8" connection from the Pfeiffer Vacuum accessories range are available for this pur- pose.
Installation Fig. 8: Connecting gas ballast external supply 1 Sinter filter Gas ballast connection opening 2 Gas ballast valve External gas supply line 3 Example of connecting coupling External gas supply Connecting gas supply 1. Turn the gas ballast valve to position “0”. 2.
The electronic drive unit starts when the mains supply is established. Establishing mains supply 1. Order a country-specific power cable from the Pfeiffer Vacuum accessories. 2. Always ensure a secure connection to the earthed conductor. 3. Plug the mains cable into the connecting plug of the electronic drive unit.
The 15-pin sub-D connection with the "remote" designation offers the possibility to operate the electron- ic drive unit via remote control. The following specifications are the factory settings for the electronic drive unit. They can be configured with the Pfeiffer Vacuum parameter set. ► Utilize the screened plug and cable.
6.2.2 Outputs The digital outputs at the "remote" connection have a maximum load limit of 24 V/50 mA per output. You can configure all listed outputs with the Pfeiffer Vacuum parameter set via the RS-485 interface (description relates to factory settings).

3. Check the set rotation speed (parameter [P:308] or [P:397]). 8.5.2 Standby mode Pfeiffer Vacuum recommends standby mode for during process and production stops. When standby mode is active, the electronic drive unit reduces the rotation speed of the vacuum pump. The factory setting is 50 % of the nominal rotation speed.
Operation Permissible rotation speed range Settings in the rotation speed mode or stand-by mode are subject to the permissible rota- tion speed range of the respective vacuum pump (technical data). The electronic drive unit adjusts the set rotation speed automatically to the next valid value. Set the rotation speed setting mode 1.
Operation 8.7 Determining effective pressure with calibration factors Gas and vapor mixtures Process gases are mostly mixtures of gas and vapor. Precise measuring of gas and vapor mixtures is only possible using partial pressure measurement instruments, for example a quadrupole mass spectrometer. The measurement signal of the pressure sensor depends on the type of gas in the Pirani range.
Operation p [hPa] Freon 12 –1 Water vapor –2 –3 –3 –2 –1 [hPa] Fig. 16: Displayed pressure Within the pressure range < 1 hPa, the display is linear. Set calibration factor at electronic drive unit ► Use [P:742] to enter calibration factor and correct displayed measured value. Alternatively: Calculating pressure for gases other than air 1.
Operation NOTICE Risk of damage from condensation in vacuum pump Exceeding the saturation vapor pressure of process media during the compression phase leads to condensation in the suction chamber. This results in an increase of the achievable ultimate pressure and to a general deterioration of the performance data of the vacuum pump as a whole. Corrosion and contamination impair service life.
8.9 Operating mode display via LED LEDs on the electronic drive unit show the basic operating states of the vacuum pump. A differentiated error and warning display is only possible for operation with the Pfeiffer Vacuum display and control unit or a PC.
► Disconnect the mains cable from the vacuum pump. NOTICE Danger of property damage from improper maintenance Unprofessional work on the vacuum pump will lead to damage for which Pfeiffer Vacuum accepts no liability. ► We recommend taking advantage of our service training offering.
We recommend that Pfeiffer Vacuum Service (PV) carry out maintenance work at level 3. Pfeiffer Vacuum will be released from all warranty and liability claims if maintenance work is not carried out properly. This also applies wherever parts other than original spare parts are used.
