Operation
7.4.4 Starting the STP Pump after Stopping
Press the "START" switch on the front panel to reaccelerate the STP pump.
The STP pump can be reaccelerated even while it is stopping.
◇ The STP pump can be reaccelerated only when the LCD displays "LEVITATION" or
"BRAKE: ***00rpm".
7.4.5 Powering OFF
Switch "OFF" the breaker on the rear panel when all three lamps of "ACCEL.", "NORMAL",
and "BRAKE" are off.
The magnetic bearing stops, the rotor lands, and the "POWER" lamp distinguishes (POWER
OFF state).
◇ NEVER switch OFF the breaker when any lamp of "ACCEL.", "NORMAL", and
"BRAKE" is on. Doing so causes such a state as a power failure.
7.4.6 Starting the STP Pump after a Safety Function Operates
A safety function operates when an abnormality occurs in the STP pump or peripheral
equipment. To restart the STP pump, remove the cause of the abnormality after the
"BRAKE" lamp distinguishes, and press the "RESET" switch.
The "FAILURE" lamp distinguishes and the safety function is released (RESET operation).
Then, press the "START" switch.
For the safety functions and troubleshooting, see Section 10, "Safety Functions" and Section
11, "Troubleshooting, Maintenance and Inspection".
