Startup Preparation

6.2.3 S

tart-up Preparation Sequence in Other Communication Means

(1) Feed the cooling water into the cooling line.
(2) Turn on the POWER switch and check that the POWER lamp. Under this condition, the

rotor of the turbo molecular pump is levitated by the magnetic bearing.

(3) Online command is demanded from the communication means and confirm the mode was

switched to the communication means mode.

(4) Evacuate the turbo molecular pump by using a backing vacuum pump.
(5) Start-up preparation is complete if the pressure in the turbo molecular pump reduces below

200 Pa.
