P.3 Power up
When the drive unit is turned on the cryocooler will start operating immediately. The
system will display the Pall LevMixer screen (see Figure 40) with the software revision
number shown. The unit will then automatically enter Power up mode. An interactive
power up process begins when the power up screen opens.
When an uncharged unit is started the user is reminded to place the charger on the
levitator head. The power up process screen prompts the user to input the type of
charger in use (4-mag or 6-mag) and shows the date and time of last power off as well
as the elapsed time of the current charging process. The selected charger is shown on
the screen.
