Function description

The following important settings are programmed in the electronic drive unit ex factory.
● Parameter [P:027] Gas mode: 0 = heavy gases
● Parameter [P:700] Set value max. run-up time monitoring: 8 min
● Parameter [P:701] Rotation speed switchpoint: 80% of the nominal roation speed
● Parameter [P:707] Set value in rotation speed setting mode: 65 % of the nominal ro-
tation speed
● Parameter [P:708] Set value power consumption: 100 %
● Parameter [P:720] Venting rotation speed at delayed venting: 50 % of the nominal ro-
tation speed
● Parameter [P:721] Venting time: 3600 s
 When water cooling is used: Open cooling water supply and check the flow.
 When sealing gas is used: Open the sealing gas supply and check the flow.
 Establish the mains for the power supply.
Risk of destroying the pump by inputting too much energy
Simultaneous loading by means of high drive power (gas flow rate, fore-vacuum pres-
sure), high heat radiation, or strong magnetic fields results in uncontrolled heating of the
rotor and may destroy the pump.
 Reduced limit values apply when combining these loads.
 If necessary consult with Pfeiffer Vacuum.
Danger of the pump being destroyed
Pumping of gases with a higher molecular mass in the wrong gas mode can lead to de-
struction of the pump.
 Ensure the gas mode is correctly set.
 Contact Pfeiffer Vacuum before using gases with a greater molecular mass (> 80).
The following operation modes are available:
● Operation without operating unit
● Operation via "remote" connection
● Operation via RS-485 and Pfeiffer Vacuum display and control units or PC
● Operation via field bus
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.
