Edwards nEXT200200 - Logic Interface Connector

3.9 Logic interface connector
The pump has 15‑w
ay logic interface connector at the end of the logic interface cable.
You can plug the logic interface connector into the manufacturer's TIC Turbo
Instrument Controller or TIC Turbo Controller. Use applicable connector mang half (not
supplied) to connect the pump to the customer equipment. Refer to Table: Logic
interface technical data on page 27 for the connector mang half type, Table: Logic
interface connector pins on page 28 for the logic interface connector pins for the
electrical connecons and Figure: Interface circuits for nEXT turbo pump controllers on
page 29 for the circuit diagrams of the connector interface.
