6.3 Function description
Operation without
operating unit
Switch on the pumping station at the master switch.
After switching on the main switch, the electronic drive unit of the turbopump per-
forms a self-test to check the supply voltage. Once the self test has been success-
fully completed, the turbopump and the backing pump begin to operate.
CAUTION
Danger of the pump being destroyed
Pumping of gases with the molecular mass> 39 in the wrong gas mode can lead to
destruction of the pump.
Ensure the gas mode is correctly set.
Contact Pfeiffer Vacuum before using gases with a greater molecular mass (> 80).
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.
CAUTION
Automatic start
After connecting the supply voltage and switching on the main switch, pumping stati-
ons without display and control unit will run up immediately.
Switch the mains switch to position "0" before plugging in the mains cable.
Switch on the mains supply immediately before operation.

nic drive unit marked "RS 485" for a longer M12 interface cable (accessory).
6.4 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.

play via LED
LEDs in the front panel of the electronic drive unit show basic operating conditions
of the turbopump. A differentiated malfunction and warning display is possible
only for operation with DCU or HPU.
Temperature monito-
ring
The drive power is reduced in case of impermissible motor temperature or imper-
missibly high housing temperature. This can cause falling below the rotation
speed switchpoint and so result in turning off the turbopump.
