Operation
6.3 Function description
Operation with DCU Consider the following manuals for the operation via Pfeiffer Vacuum display
and control units:
•Operatinginstructions"DCU"
•Operatinginstructions"Electronicdriveunit"
Switch on the mains supply via the main switch.
Switch on the pumping station via button "ON/OFF" on the DCU 002.
Settings are possible with the extended parameter set at the DCU.
Settings are possible via the RS485 by using DCU, HPU or PC.
Use of the DCU as a remote control
The display and control unit can be removed from the pumping station and used
as a remote control.
Switch off the pumping station at the master switch.
Disconnect the mains plug.
Unscrew and remove the 4 fastening screws with washers from the front panel
of the display and control unit.
Lift out the display and control unit from the casing.
–Becarefulofthecasingseal.
Swap the connecting cable between the display and control unit and the electro-
nic drive unit marked "RS 485" for a longer M12 interface cable (accessory).
6.4 Saving energy
Depending on the power consumption of the turbopump the electronic drive unit
controls the backing pump operation (type dependant). A relation to the supplied
fore-vacuum pressure is derived from the power consumption. Control of the back-
ing pump can reduce the overall power consumption of the pumping station and
the operating temperature of the backing pump as well.
•Intermittendmodeonlyfordiaphragmpumps
•NocontrolforDuoLine
The diaphragm pump is switched on and off in dependence of the turbopump's
power consumption. The switching thresholds for the backing pump are adjustable
via the DCU. Fluctuations in the power consumption of idling turbopumps and
type-dependent varying fore-vacuum pressures of the backing pumps require the
switching thresholds to be set separately for the intermittend mode.
Parameter [P:794] = 1 (Displaying the extended parameter set at the DCU)
Parameter [P:025] = 1 (Intermittend operation).
Configure thresholds [P:710] and [P:711] according to the operating instruc-
tions "Electronic Drive Unit".
WARNING
Danger due to open high vacuum flange
The rotor of the turbopump turns at high speed. If the high vacuum flange is open,
there is a danger of cut injuries and that the pump can be destroyed by objects falling
into it.
Never operate the pump with an open high vacuum flange.

Operation
6.5 Operation with gas ballast valve
Steam or moisture from pumped media can condense in the vacuum pump and
hence impair the suction performance.
Letting in gas ballast improves the discharge of condensate, and the pump
achieves the specified final vacuum more quickly. The gas ballast valve can be re-
placed with a flushing gas connection if necessary.
For operation with gas ballast, please refer to the operating manual for the ba-
cking pump.
6.6 Operation with fore-vacuum valve
The fore-vacuum safety valve (optional accessory) is located in the fore-vacuum
line between the turbopump and the backing pump. It protects the process vacuum
and the turbopump from inadvertent venting upon stillstand of the pumping sta-
tion (backing pump) or power failure. The valve is closed currentless.

•Pumpingstation"Off"=Fore-vacuumsafetyvalveclosed
6.7 Switching off and venting
Switching off After the turbopump is switched off, it must be vented to avoid contamination due
to particles streaming back from the fore-vacuum area.
Switch off the pumping station via the "ON/OFF" button on the DCU.
Venting (possibilities, see below)
Switch off the pumping station at the master switch.
For water cooling: Shut off the water supply.

Basic information for the rapid venting
Venting of the vacuum chamber in two steps. Ask for details on individual solutions
from Pfeiffer Vacuum.
Vent for 20 seconds at a rate of pressure rise of max. 15 mbar/s.
