Screen controls require that he user select the type of charger needed for the
impeller to be used for mixing (4-mag or 6-mag). This is a necessary step in the
completion of power up. The Charger selection screen (see Figure 43) is accessible
by pressing the button labeled “NONE”. Choose the appropriate charger using the
arrows and press enter. The selected charger is displayed on the power up screen
(see Figure 44).
Upon completion of the prescribed charging time (35 min) the charging status will
indicate “Charged”. If the system already meets the second condition – a charger
is selected different from “NONE” – a blinking READY button will appear on the
screen (see Figure 45). By pressing the READY button the user arrives at the Main
Menu screen with “common” access level (see Figure 46). At this point the unit is
ready for mixing.

2)
Superconductors are partially charged. Power down is required. The on screen
notification shows “COUPLING INSUFFICIENT!”
The Operator must:
a)
Turn the unit off.
b)
Wait for at least 25 min.
c)
Follow the Charging Procedure as described in Section H.
This mode can occur if the unit was powered off for 10
min to 25 min after charging
OR if the unit was powered off during the charging process. At least 25 min of
power-off time is required to reset the superconductors for charging.
IMPORTANT:
Powering ON of the unit during the required power-off time will restart the
25 min power-off period resulting in an extension of the overall wait time.
3)
Superconductors are completely charged. Once the READY button is shown on the
power up screen and the correct magnet number is selected the Unit is ready for
use. Press the READY button to proceed to the Main Menu.
This mode can also occur if the unit is in fully charged condition and is powered off
for less than 10
minutes.
