7 Parameter set
7.1 General
Important settings and function-related characteristics are factory-programmed into the electronic drive
unit as parameters. Each parameter has a three-digit number and a description. The use of the parame-
ter is possible via Pfeiffer Vacuum displays and control panels, or externally via RS-485 using Pfeiffer
Vacuum protocol.
The vacuum pump starts in standard mode with factory default pre-set parameters.
Non-volatile data storage
When switching off or in the event of unintentional voltage drop, the parameters and the
operating hours stay saved in the electronics.
