STP-H600/H1000 Series Instruction Manual

5.6Remote Operation

Slide the "MANUAL/REMOTE" changeover switch on the STP control unit rear panel to "REMOTE."

5.6.1Powering ON

Switch ON the breaker on the STP control unit rear panel,

(to prevent incorrect operation, a metal fitting is attached to the breaker. Loosen the screw, lift the metal fitting and secure it ).

The magnetic bearing functions and the rotor levitates (POWER ON state). The "POWER ON/OFF" switch built-in lamp lights.

5.6.2Starting/Stopping the STP Pump

There are three methods of starting/stopping the STP pump. Use one of them.

Table 5.1 Starting/Stopping the STP Pump During Remote Operation

Method	Terminal	Starting the Pump	Stopping the Pump
	Block
1	TB5	1) Short the circuit between (3) -	Open the circuit
		(2) (STOP IN).	between (3) - (2) (STOP
		2) Short the circuit between (2) -	IN).
		(1) (START IN) for 0.3 seconds
		or more.
		However, when inputting the
		signal simultaneously with
		switching ON the breaker on
		the rear panel, continue to
		short the circuit for 5 seconds
		or more.
2	TB5	Short the circuit between (1) - (3)	Open the circuit
		(START/STOP IN).	between (3) - (1)
			(START/STOP IN).
3	TB6	Input 25 to 250 V AC or 24 to 48 V	Open the circuit
		DC between (2) - (1) (START/STOP	between (2) - (1)
		IN).	(START/STOP IN).
		With DC, the (+) side can be
		connected to either (2) or (1).

5.6.3Starting the STP Pump After Stopping

Perform the rotation procedures to reaccelerate the STP pump. See Section 5.6.2, "Starting/Stopping the STP Pump."

The STP pump can be reaccelerated even while the STP pump is stopping.
