Pump Connector; J5 - Gauge Connector - Varian Turbo-V 81-AG Manual De Instrucciones

Pump Connector

A five-meter long cable is available to connect the
controller to the pump. The following figure shows the
controller output connector configuration where pins:
•
A-F = pump temperature sensor
•
B-C-D = 75 Vac 3-phase output to pump motor
stator
•
E = EARTH PROTECTION
Controller-to-Pump Connector
J5 – GAUGE CONNECTOR
This connector is available to connect "EyeSys
Mini-IMG" gauge with it's extention cable (see
orderable parts table).
The pressure can be read by dispaly or by serial line
(win. 224) or by REMOTE I/O on Programmable Analog
Out (in this case the controller replicates the signal
coming from the gauge).
Gauge Connector
The Mini-IMG gauge is intended for high vacuum use,
so with pressure
misinterpreted and a "false" pressure is displayed. Use
a transition gauge to understand if the reading is really
under 50 mTorr or not.
