Pfeiffer Vacuum DCU 002 User Manual

5 Parameter set
5.1 General
Important settings and function-related variables are factory-programmed into the electronic drive unit
as parameters. Each parameter has a three-digit number and a description. The use of the parameter is
possible via Pfeiffer Vacuum displays and control panels, or externally via RS-485 using Pfeiffer Vac-
uum protocol.
The pump starts in standard mode with factory default pre-set parameter.
When switching off or in the event of unintentional voltage drop, the parameters
and the operating hours stay saved in the electronics.
# Three digit number of the parameter

5.2 Additional parameter for the DCU
Additional parameter in the control unit
The basic parameter set is set in the electronic drive unit ex-factory. For controlling
connected external components (e.g. vacuum measuring instruments), additional
parameters (extended parameter set) are available in the corresponding Pfeiff-
er Vacuum display and control units.
