STP-200/300/400 Series Instruction Manual

5.5.5 Powering OFF

1) When both the "ACCELERATION" and "NORMAL OPERATION" lamps are

off and the ROTATION meter shows a full-scale deflection to the red:

i. Press the "POWER ON/OFF" switch. The switch pops up into the

unlocked position, the magnetic bearing stops, and the rotor lands

(POWER OFF state).

The "POWER ON/OFF" switch built-in lamp goes out.

ii. Switch "OFF" the breaker on the rear panel.

2) When either of the "ACCELERATION" and "NORMAL OPERATION" lamps

is lit or the ROTATION meter does not show a full-scale deflection to the red:

i. Even by pressing the "POWER ON/OFF" switch to switch it "OFF," the

rotor does not land, the pump's operation state remains unchanged, and

the "POWER ON/OFF" switch built-in lamp remains lit.

When the number of rotations goes down to approx. 3,000 rpm or less,

the magnetic bearing stops, the rotor lands, and the "POWER ON/OFF"

switch built-in lamp goes out.

ii. Switch "OFF" the breaker on the rear panel.

◇ The brake of the STP pump disengages at approx. 3,000 rpm, after

which the STP pump still rotates by inertia.

Powering OFF immediately after pressing the "MOTOR STOP" switch

or while either of the "ACCELERATION" and "NORMAL OPERATION"

lamps is being lit causes the touch down bearing to touch the rotor

resulting in a noise when the brake disengages. Although this is

not an indication of abnormality, repetitions of such an operation will

expedite the wear of the touch down bearing.

Such operations will expedite the wear of the touch down bearing.

It is recommended to power "OFF" the STP pump after it stops

thoroughly.

◇ Although the POWER OFF operations may cause an

"Abnormality/Error Warning" lamp to light and an alarm signal to be

output from the REMOTE CONNECTOR, this is not an indication of

abnormality.

This state is released within 5 seconds.
