INSTRUCTIONS FOR USE
12/94
CN929-7015M002
Step Mode of Operation
The Step mode has to be chosen in order to increase
the performance of the pump and to read at very low
pressure without influence of leakage current.
In Step mode the E-Net Dual Controller chooses the
best output voltage according to the pressure into the
pump (see the following figure).

Powering On the Controller from the Front
Panel (LOCAL Mode)
NOTE
To switch on the H.V. the external interlock must be
closed (connector inserted).
If no external connection is made, insert the interlock-
closing jumper that are provided with the unit.
Proceed as follows to power on the controller and
enable the voltage on the H.V. connectors:
•
Insert the cable from the pump and the interlock
loopback pin of the H.V. cable into the related
connectors on the rear panel.
•
Set the power switch on the rear panel to the ON
position.
•
Set the ENABLE HV switch on the front panel to
the ON position.
•
Press the CHANGE CONFIG and HV ON/OFF
buttons together (ON LED lit).
NOTE
With only one H.V. circuit installed both rows on the
display are dedicated to pump number one, while with
two circuits installed each row is dedicated to a different
pump.
Starting the Pump
To start the pump, press the corresponding CHANGE
CONFIG and HV ON/OFF buttons together; the ON
LED will come on.
Stopping the Pump
To stop the pump press the corresponding CHANGE
CONFIG and HV ON/OFF buttons together; the ON
LED will go off.
MAINTENANCE
The E-Net Dual Controller does not require any
maintenance. Any form of servicing on the unit must be
performed by authorized personnel.
If servicing is needed, contact Varian Technical Support
or subscribe to the “Varian Advanced Exchange
Service” where the faulty controller is replaced by a
refurbished one.
If the controller needs to be scraped, proceed to do so
in compliance with the specific national norms.
DISPOSAL
Meaning of the "WEEE" logo found in labels
The following symbol is applied in accordance with the
EC WEEE (Waste Electrical and Electronic Equipment)
Directive.
This symbol (
valid only in countries of the European
Community
) indicates that the product it applies to
must NOT be disposed of together with ordinary
domestic or industrial waste but must be sent to a
differentiated waste collection system.
The end user is therefore invited to contact the supplier
of the device, whether the Parent Company or a
retailer, to initiate the collection and disposal process
after checking the contractual terms and conditions of
sale.
