6.2 Operating modes
The turbopump can be operated in different ways.
● Operation without control unit
● Operation via connection "X3"
● Operation via interface RS-485 and Pfeiffer Vacuum display and control unit or PC
● Operation via connection "E74"
● Operation via field bus
6.2.1 Operation without operating unit
Notes on operation without control unit
1. Only use the approved Pfeiffer Vacuum connection cables with bridges on the "X3" connection on
2. Only switch on the power supply of the turbopump immediately before operation.
After applying the operating voltage, the electronic drive unit carries out a self-test to check the supply
voltage. After completing the self-test successfully, the turbopump starts and activates connected addi-
tional equipment according to the configuration.
6.2.2 Operation via multi-function connection "X3"
Remote control is available via the 15 Pole D-Sub connection with the "X3" designation on the electron-
ic drive unit. The accessible individual functions are mapped to "PLC levels".
Instructions for remote control operation
► See the electronic drive unit operating instructions.
6.2.3 Operation via Pfeiffer Vacuum display and control unit
The connection of a Pfeiffer Vacuum display and control panel permits the controlling of the turbopump
via the parameters fixed in the electronic drive unit.
Instructions for operation with display and control unit
1. When handling the Pfeiffer Vacuum display and control units, observe the respective operating in-
2. Observe the electronic drive unit operating instructions from the scope of delivery of the vacuum
3. Connect the display and control unit to the "X3" multi-function connection of the electronic drive
4. Switch on the turbopump current supply via the external power supply pack or the display and
6.2.4 Operation via connection "E74"
Operation is possible via the 15-pole D-sub connection with the "E74" designation on the electronic
drive unit. Besides the signals defined in the Directive SEMI E74-0301, the connection is provided with
an inverted alarm signal and an analog output.
Instructions for operation with E74
► See the operating instructions of the electronic drive unit with E74 version.
6.2.5 Operation via field bus
Integrating and operating Pfeiffer Vacuum turbopumps in the customer's field bus system is possible
when using an electronic drive unit with a corresponding connection panel.
Automatic start
After bypassing the contacts at pins 2, 5 and 7 on the "X3" connection or when using a con-
nection cable with bridges and applying the supply voltage, the turbopump starts up imme-
diately.
