Operation
6.2 Operating modes
The turbopump can be operated in different modes.
● Operation without control unit
● Operation via connection "E74"
● Operation via "remote" connection
● Operating via RS-485 interface from Pfeiffer Vacuum control unit or PC
● Operation via field bus
6.2.1 Operating without operating unit
Instructions for operation without control panel
1. Use only the approved Pfeiffer Vacuum mating plug with bridges on the connection of the elec-
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.
