Tbl. 30: Behavior and meaning of the LED display
7.10.2 Temperature monitoring
If threshold values are exceeded, output signals from temperature sensors bring the turbopump to a
safe condition. Depending on the type, temperature thresholds for warning and error messages are im-
mutably stored in the electronic drive unit. For information purposes, various status requests are set up
in the parameter set.
●
In order to avoid switching off the turbopump, the electronic drive unit already reduces the power
consumption in case of exceeding the warning threshold for excess temperature.
─
Examples are an impermissible motor temperature, or impermissibly high housing tempera-
ture.
●
Further reduction of drive power and thus decreasing speed can potentially lead to underrun the
rotation speed switchpoint. The turbopump switches off.
●
Exceeding the temperature threshold for error messages switches off the turbopump immediately.
7.11 Switching off unit
Procedure
1. Switch off the power supply with the "POWER" mains switch on the rear of the unit.
2. Disconnect the power supply pack from the mains to disconnect the current supply completely.
