when power button is
pressed.

Main power fuse
is burned out

Contact service personnel

No white light when
power is on while unit
started

Power button
LED is burned out

Contact service personnel

Excessive wobbling of
levitated impeller
during use

Unit improperly
charged

Power off the unit. Wait for 25 min or more
and charge the unit again.

Misalignment of
charger position
during charging

Inspect the top surface of levitation head
for levelness.
Inspect the charger for mechanical
damage.

Charger magnet
damaged

Recharge the unit with another charger and
perform the levitation test.

Cryomodule
malfunction

Call for technical service.

Impeller doesn’t
levitate properly after
charging completed.

Unit improperly
charged

Power off the unit. Wait for 25 min or more
and charge the unit again.

Power cord is
unplugged from
the unit

Ensure the power cord is properly attached
to unit.

Cryomodule
malfunction

Call for technical service.

Cryocooler
controller
malfunction

Call for technical service.

Unsmooth rotation of
Impeller with jerking
movements,
accompanied by
knocking noise.

Coupling out of
specification

Recharge the unit.

Loose timing belt Call for technical service
Impeller is
overloaded with
torque

Inspect impeller load in application, reduce
load if possible

Low battery
notification

Battery low

Elevated risk of memory corruption and
unreliable operation. Call for technical
service.
