3.5 Logic interface data
The pumps have a 15
‑
way D
‑
type logic interface connector located on the user interface
panel ( Figure: nXDS scroll pump on page 11 , item 7). The logic interface connector can
be plugged directly into the 200 W Turbo Instrument Controller (TIC) or Turbo Controller,
or Turbo and Active Gauge controller (TAG). A suitable connector mating half must be
used (not supplied) to connect the nXDS pump to the customer control system. Refer to
Table: Logic interface technical data on page 21 for the interface technical data and
Table: Logic interface connector pins on page 22 for the logic interface pins for the
electrical connections.
