    1 About this manual 1.1 Validity This operating manual is for customers of Pfeiffer Vacuum. It describes the functioning of the designated product and provides the most important information for safe use of the unit. The description follows applicable EU guidelines. All information provided in this operating manual refer to the current state of the product's development.

  • Page 4: 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.

    The Pfeiffer Vacuum parameter set 7.3 Configuring the connections The electronic drive unit is pre-configured in the factory. Thereby the turbopump is im- mediately operational with the necessary functions. The connections of the electronic drive unit can be configured to suit individual requirements using the parameter set.

  • Page 33 The Pfeiffer Vacuum parameter set The rotation speed switch point can be used for the message "Pump operational for the Adjusting the rotation process". Overrunning or underrunning the active rotation speed switch point activates speed switchpoint or deactivates a signal at the pre-configured output on the electronic drive unit and at the status parameter [P:302].
  • Page 34  Adjust the parameter [P:707] to the desired value in %.  Parameter [P:026] = 1  Read the parameters [P:308]/[P:397]. Pfeiffer Vacuum recommends standby mode for the turbopump during process and pro- Standby duction stops. When standby mode is active, the electronic drive unit reduces the rotation speed of the turbopump.
  • Page 35 Pfeiffer Vacuum recommends the intermittend mode between 5 and 10 mbar. A pressure gauge and a dosing valve are required to set the switching thresholds.
