STP-iXA3306 Series Turbomolecular Pump
Pins for choosing the input signal.
When using voltage input, short the circuits between (19)-(37).
Pins for inputting the START signal.
The following two methods are available:
1) Supply 12 to 24 VDC to the circuits between (21)-(1). Then,
supply 12 to 24 VDC to the circuits between (3)-(1) for 0.3
seconds or more.
However, when inputting this START signal simultaneously
with switching "ON" the STP pump, continue to supply
voltage to these pins for 10 seconds or more.
2) Supply 12 to 24 VDC to the circuits between (3)-(1).
In this case, (21) is not used.
Pins for inputting the STOP signal.
1） When 1) above is used to start the STP pump, shutoff
voltage to the circuits between (21)-(1) to stop the STP
pump.
2） When 2) above is used to start the STP pump, shutoff
voltage the circuits between (3)-(1) to stop the STP pump.
Pins for inputting the RESET signal.
When a safety function operates, remove the cause of the
abnormality/error after confirming the STP pump has stopped.
When the cause of the abnormality/error is removed, supply 12
to 24 VDC to the circuits between (22)-(1) for 0.3 seconds or
more to reset the failure signal (The "FAILURE" LED
extinguishes).
