9 Malfunctions
9.1 General
Turbopump and electronic drive unit malfunctions always result in a warning or error
message. In both cases, the electronic drive unit outputs an error code. Operating mes-
sages are generally displayed via the LEDs on the electronic drive unit. If an error occurs,
the turbopump and connected devices will be switched off. The selected venting mode
will be triggered after the preset delay.
9.2 Operation display 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 opera-
tion with DCU or HPU.

9.3 Error codes
WARNING
Automatic start-up after power failure or malfunction acknowledgement
The function "pumping station" of the electronic drive unit remains active after power
failure or errors that lead to shut down the pump or the system. The turbopump runs up
automatically after power ist restored or malfunction acknowledgement.
 Switch off the function "pumping station" if necessary.

Provide safety measures against interference in the high vacuum flange while the tur-
bopump is running.
