6.2 Operating modes
The turbopump can be operated in different modes.
● Operation without control unit
● Operation via connection "E74"
● Operation via "remote" connection
● Operation via interface RS-485 and Pfeiffer Vacuum display and control unit or PC
● Operation via field bus
6.2.1 Operation without operating unit
Automatic start
When using the supplied mating plug on the electronic drive unit or bridging contacts ac-
cording to the terminal lay-out, the turbopump is ready for operation. Once the supply volt-
age is provided, the turbopump starts up immediately.
Instructions for operation without control panel
1. Use only the approved Pfeiffer Vacuum mating plug with bridges on the connection of the elec-
tronic drive unit.
2. Switch on the mains supply of the turbopump only 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 "remote"
Remote control is available via the 26-pole D-sub connector with the “remote” designation on the elec-
tronic drive unit. The accessible individual functions are mapped to "PLC levels".
Instructions for remote control operation
► See the operating instructions of the electronic drive unit for the standard version.
6.2.3 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.
6.2.4 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 unit, observe the associated operating in-
structions:
– "DCU" operating instructions available from the
– "HPU" operating instructions available from the
2. Observe the electronic drive unit operating instructions included in the scope of delivery for the
turbopump.
3. Connect the display and control unit to the connection "RS-485" on the electronic drive unit.
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.
