<Ⅱ. Operation after a Power Recovery>
1) MANUAL Operation
The STP pump continues decelerating even after a power recovery.
Press the "START" switch to reaccelerate the STP pump.
2) REMOTE Operation
i. When the power is recovered at approx. 3,000 rpm or more:
• When the START signal is input to the REMOTE CONNECTOR
after a power recovery, the STP pump reaccelerates.
• When the START signal is not input to the REMOTE CONNECTOR
after a power recovery, the STP pump continues the BRAKE
operation.
ii. When the power is recovered at less than 3,000 rpm (after the rotor
lands):
• When the POWER ON signal is input to the REMOTE
CONNECTOR after a power recovery, the rotor re-levitates.
• When the POWER ON and START signals are input to the
REMOTE CONNECTOR after a power recovery, the rotor
re-levitates and the STP pump reaccelerates.
• When the POWER ON signal is not input to the REMOTE
CONNECTOR after a power recovery, the pump's state remains
unchanged.

: Depending upon the condition of the STP control unit, it may detect a power failure of approx. 35 milliseconds
to less than 50 milliseconds.
