Operation with the Pfeiffer Vacuum parameter set
9.4.1
Factory settings
The electronic drive unit is pre-programmed in the factory. This guarantees proper, reli-
able turbopump operation without the need for additional configuration.
9.4.2
Checking the adjustments
Before operating with parameters, check set values and control commands for their
suitability for the pumping process.
Remove the remote plug from electronic drive unit if required.
