PUMP FIXING
WARNING!
If a rotor failure occurs, the connection of the pump to the sys-
tem could be subjected to a significant torque. If the connection
is not sufficient to withstand that torque, the pump could detach
from the system or the motor housing could detach from the
pump envelope. In this case metal fragments could be pro-
jected from the pump or system, which could cause serious
injury or death and/or damage to surrounding equipment.
Fix the TV 1001 Navigator in a stable position mounting the
inlet flange of the turbopump to the system counter-flange, with
a connection capable of withstanding a torque of 8900 Nm
around its axis.
For example the ISO-K flange can be fixed using high strength
steel clamps (like Varian model IC63250DCMZ).
The following table shows, for each flange, the necessary num-
ber of IC63250DCMZ clamps and the relevant fixing torque.

The class of the steel screws for "F" flange must be > 8.8
The turbopump with ConFlat inlet flange must be fixed to the
vacuum chamber by means of the appropriate Varian hard-
ware. See the appendix "Technical Information" for a detailed
description.
The TV 1001 Navigator ca be installed in any position.
NOTE
The TV 1001 Navigator cannot be fixed by means of its base.
The TV 1001 Navigator belongs to the second installation (or
overvoltage) category as per directive EN 61010-1. Connect the
device to a mains line that satisfy the above category.
The TV 1001 Navigator has Input/Output and serial communi-
cation connectors that must be connected to external circuits in
such a way that no electrical part is accessible.
Be sure that the insulation of the device connected to the TV
1001 Navigator is adequate even in the case of single fault as
per directive EN 61010-1.
For installation of optional accessories, see "Technical Informa-
tion".
USE
This paragraph details the fundamental operating procedures.
Make all electrical an pneumatic connections before the use of
the system.
While heating the vacuum chamber, the temperature of the inlet
flange must not exceed 120 °C.
WARNING!
Never use the turbopump when the inlet flange is not con-
nected to the vacuum chamber or is not blanked.
Do not touch the turbopump or any of its accessories during the
heating process. The high temperatures may cause burns.

CAUTION
Avoid impacts, oscillations or harsh movements of the pump
when in operation. The bearings may become damaged.
Use air or inert gas free from dust or particles for venting the
pump. The pressure at the vent port must be less than 2 bar
(above atmospheric pressure).
For pumping aggressive gases, these pumps are fitted with a
special port to allow a steady flow of inert gas (like N
pump bearing protection (see the appendix "Technical Informa-
tion").
When employing the pump for pumping toxic, flammable, or
radioactive gases, please follow the required procedures for
each gas disposal.
Do not use the pump in presence of explosive gases.
Switching on and Use of TV 1001 Navigator
To switch on the TV 1001 Navigator it is necessary to supply
the mains. The integrated controller automatically recognizes
the interlock and start signals presence and start up the pump.
The first pump start up is in "Soft Start" mode. When the start
up cycle is finished, the "Soft Start" mode automatically is dis-
abled, and the following start ups are without the "Soft Start"
mode. To re-enable the "Soft Start" mode it must be activated
by the suitable software command (see the paragraph "RS
232/485 COMMUNICATION DESCRIPTION" in the appendix
"Technical Information").
The green LED located on the TV 1001 Navigator base front
panel indicates with its flashing frequency the system operating
conditions:
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.
TV 1001 Navigator Switching off
To switch off the TV 1001 Navigator it is necessary to remove
the mains. The integrated controller immediately stops the
pump.
The Turbo-V controller must be powered with 3-wire power cord
(see orderable parts table) and plug (internationally approved)
for user's safety. Use this power cord and plug in conjunction
with a properly grounded power socket to avoid electrical shock
and to satisfy CE requirements. High voltage developed in the
controller can cause severe injury or death. Before servicing the
unit, disconnect the input power cable.
Emergency Stop
To immediately stop the TV 1001 Navigator in an emergency
condition it is necessary to remove the supply cable from the
mains plug.
