STP-301/451 Series Instruction Manual
8-9
Operation
8.3.2 Remote Output Signals
Use output signals according to Table 8.7 and Figure 8.4.
This output signal operates in both manual operation and remote operation.
No.4 of the DSW-B DIP switch operates in "ON/OFF" both states.

Pin Description
(5) (17)
REMOTE
N.O OUT
Pins for outputting the STP pump REMOTE SELECTION state
signal.
When the MANUAL/REMOTE changeover switch on the STP front
panel is set to ON (remote side), these pins are closed (REMOTE
operation).
However, during power failure backup operation, this signal is not
output.
(6) (18)
ROTATION
N.O OUT
Pin for outputting the rotational state signal.
These pins are closed when the STP pump is in rotation.
However, during power failure backup operation, this signal is not
output.
(It corresponds to the pin for outputting the "POWER ON" signal of
the STP-200/300/400 series.)
(7) (19)
EMERGENCY
OPERATION
N.O OUT
Pins for outputting the EMERGENCY OPERATION state signal.
These pins are closed when failures are detected as follows.
z Abnormal state of magnetic bearing
z Excessive Vibration
However, during power failure backup operation, this signal is not
output.
(8) (20)
FAILURE
N.O OUT
Pins for outputting the FAILURE state signal.
These pins are closed when failures are detected as follows.
z Motor driver overload
z Overheating inside the STP pump
z Overheating inside the STP control unit
z Overspeed
However, during power failure backup operation, this signal is not
output.
(9) (21)
OVER
TEMPERATUR
N.O OUT
Pins for outputting the OVER TEMPERATURE state signal.
These pins are closed when overheating inside the STP pump is
detected.
However, during power failure backup operation, this signal is not
output.
(11) (23)
ACCELERATION
N.O OUT
Pins for outputting the ACCELERATION state signal.
These pins are closed when the STP pump is in acceleration.
(11) (24)
NORMAL
OPERATION
N.O OUT
Pins for outputting the NORMAL OPERATION state signal.
These pins are closed when the STP pump is in rated operation.
(10) (22)
Not used.
(It corresponds to the pin for outputting the "BATTERY
OPERATION" signal of the STP-200/300/400 series.)
(12)
Not used. It is connected to the frame ground.
