4.3. Switching OFF And Venting The power limitation serves to protect the pump against ther- mal over-oading. In order to avoid rotation speed fluctuations Before coming to rest after switching off, the turbopump must it is recommended to set, in rotation speed setting mode, the be vented in order to prevent contamination.
4.6. Operations With The DCU 001/DCU 200 Motor, Turbopump When the pumping station is switched on and once the self Operations with the DCU 001 or DCU 200 should be carried out test has been successfully completed (duration approximate- in accordance with the relevant Operating Instructions ly 10 seconds), the turbopump is set in operation.
Switching Outputs Switching outputs 1 and 2 can be loaded with a maximum 24 V / 50 mA per output. The following functions are assigned to the switching outputs: Switching output 1: Active high when the rotation speed switchpoint is attained. The switchpoint for the turbopump is set at 80% of the nominal rotation speed.
