Use of Turbo-V 2K-G
How to start the system up
Before starting the system, please check that the mating I/O
connector is unplugged. If the system is connected to a remote
I/O, make sure the stop signal (see para. "J1-REMOTE I/O" of
annex "Technical Information") is given.
To start the system please follow the following steps:
9.
unplug (if present) the system mating I/O connector
10. plug on the mains
11. pump the vacuum chamber down to 0.1 mbar
12. give the Turbo-V 2K-G a start signal by one of the follow-
ing methods:
a.
connecting the provided mating I/O connector
b.
giving a remote start signal through the I/O con-
nector (see para. "J1-REMOTE I/O" of annex
"Technical Information")
c.
giving a remote start signal via the serial RS
232/485 interface (see para. "RS232/RS 485
Communication Description" of annex "Techni-
cal Information").
WARNING!
When power is supplied and factory default 15 pin mating con-
nector is inserted, the Turbo-V 2K-G will start automatically.
!
CAUTION
The controller is furnished already mechanically and electrically
connected to the pump. Detaching of the controller from the
pump must be carried out by authorized Varian Vacuum Tech-
nologies personnel only.
NOTE
When you run the Turbo-V 2K-G for the very first time, the con-
trol unit automatically starts the system with a special proce-
dure which protects the bearings from possible damages
(SOFT START). The system is launched step by step at full
speed in a time variable from 10 mins up to 1 hour. After the
system has reached the full speed, the soft start procedure is
disabled and following starts are performed in the normal way.
NOTE
In order to maintain the IP-54 protection level you must use
only the connectors provided with the pump. Use connectors
PN: 969-9957 or 969-9958 for the power cable and fix it to the
controller by means of the suitable retaining bracket (see the
following figure). Use this power cord and plug in conjunction
with a properly grounded power socket to avoid electrical shock
and to satisfy CE requirements.
The system is provided with a green status led signal.
The green LED located on the Turbo-V 2K-G base front panel
indicates with its flashing frequency the system operating condi-
tions:
•
with no flashing: the pump is normally rotating;
•
slowly flashing (period of about 400 ms): the system is in
ramp, or in braking, or in Stop, or in "Waiting for interlock"
status;
•
fast flashing (period of about 200 ms): error condition.
How to stop the system
To stop the pump you can use one of the following methods:
7.
unplugging the provided mating I/O connector
8.
giving a remote stop signal through the I/O connector (see
para. "J1-REMOTE I/O" of annex "Technical Information")
9.
giving a remote stop signal via the serial RS 232/485 inter-
face (see para. "RS232/RS 485 Communication Descrip-
tion" of annex "Technical Information").
Emergency Stop
To immediately stop the Turbo-V 2K-G in an emergency condi-
tion it is necessary to remove the mains.
MAINTENANCE
The Turbo-V 2K-G does not require any maintenance. Any work
performed on the system must be carried out by authorized
personnel.
Before carrying out any work on the system, disconnect it from
the mains, vent the pump by opening the appropriate electro
valve, wait until the rotor has stopped turning and wait until the
surface temperature of the pump falls below 50 °C.
In the case of breakdown, contact your local Varian service
center who can supply a reconditioned system to replace that
broken down.
Before returning the system to the constructor for repairs, or
replacement with a reconditioned unit, the "Health and Safety"
sheet attached to this instruction manual must be filled-in and
sent to the local sales office. A copy of the sheet must be in-
serted in the system package before shipping.
If a system is to be scrapped, it must be disposed of in accor-
dance with the specific national standards.
