During operation, the following environmental conditions must
be respected:
−
maximum pressure: 2 bar above atmospheric pressure
−
temperature: from +5 °C to +35 °C (see the diagram pres-
sure-temperature in the appendix "Technical Information")
−
relative humidity: 0 - 95% (non-condensing)
In the presence of magnetic fields the pump must be protected
using a ferromagnetic shield. See the appendix "Technical In-
formation" for detailed information.
The TV 301SF Navigator must be connected to a primary pump
(see "Technical Information").
The TV 301SF Navigator can be installed in any position. Fix
the TV 301SF Navigator in a stable position connecting the inlet
flange of the turbopump to a fixed counter-flange capable of
withstanding a torque of 1000 Nm around its axis.
The turbopump with ISO inlet flange must be fixed to the vac-
uum chamber by means of clamps or claws. The following table
shows, for each flange and fixing device, the necessary number
of clamps or claws and the relevant fixing torque.

NOTE
The TV 301SF Navigator cannot be fixed by means of its base.
!
CAUTION
The TV 301SF 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 301SF 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
301SF 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.

INSTRUCTIONS FOR USE
!
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").
WARNING!
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 301SF Navigator
To switch on the TV 301SF 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 301SF 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 301SF Navigator Switching off
To switch off the TV 301SF Navigator it is necessary to remove
the mains. The integrated controller immediately stops the
pump.
WARNING!
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 301SF Navigator in an emergency
condition it is necessary to remove the supply cable from the
mains plug.
