Installation; Pump Connector; I/O Specifications; 9-Pin "D" Type Connector Pin Assignement - Varian Turbo-V 300 SQ 275 Instruction Manual

INSTALLATION

Inspect the controller for any shipping damage.
Should the controller be connected to a host computer
via the-RS-232 interface, a suitable cable must be
prepared.
In the following paragraphs are detailed the input/output
signals.
The box installed into the customer system must be
positioned so that cold air (forced or natural convection)
can flow around.

Pump Connector

stator (phase S).
•
Pin B 80 Vac 3-phase output to pump motor stator
(phase R).
•
Pins A/F Pump temperature sensor.
•
Pin E Ground
