<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
When the START signal is input to the REMOTE input terminal at a power recovery to reaccelerate the STP pump.
When the START signal is not input to the REMOTE input terminal after the power recovery, the STP pump continues the BRAKE operation.
NOTICE
◇Establish a sequence so that power can be supplied to the STP control unit immediately after a power recovery.
Table 6.1 shows the states of lamps and the REMOTE output signal at a power failure.
Also, Table 6.2 shows operations of the STP pump after a power recovery.
