Remote-control Connector
6.7.1 Specification
Table 6-3 START/STOP According to Remote-control Signals
This turbo molecular pump is provided with
remote-control connector for connection with
remote operation, ALARM signals, etc.
(Refer to Fig. 6-2, Fig. 6-3, Table 6-3)
For connection with this connector, cable with
shield is necessary. The shield of the cable
should be connected to case.
For remote-controlled operation, need to change
