5. Monitoring Operations
5.1. Operations Display Via LED
Certain operations modes of the turbopump and the TC 600
can be ascertained via the two integrated LEDs located on
the front panel of the TC 600.
The following operations modes are displayed:
5.2. Turbopump Temperature
Management
Where impermissible motor temperatures are involved or the
temperature of the casing is too high, the motor current is
reduced.
This can lead to dipping below the set rotation speed switch-
point and results in the turbomolecular pump being switched
off.
LED on the TC 600 glows red: Collective malfunction.
