with ceramic balls.

The turbopumps must

nnoott

be transported when
filled with lubricant.
When being fitted into or dismantled from a
system, turbopumps may only be positioned as
shown in Section 3.2. Other positions can cause
the pumps to be contaminated with lubricant.

Proper use

–The Turbomolecular Pumps TMH/TMU 1601 P and

TMH/TMU 1601 PC may only be used for the purpose of
generating vacuum.

–The Turbomolecular Pumps TMH/TMU 1601 PC (please

see the rating plate) are designed to pump corrosive gases
and vapours. Where corrosive gas processes are involved,
gas bonding and particels which can damage the surfaces
of the pump can be produced. The motor and bearing
compartments have to be protected with sealing gas.

– The turbopumps may only be used to pump those media

against which they are chemically resistant. For other
media the operator is required to qualify the pumps for the
processes involved.

–If the process produces dust, the maintenance intervals

must be specified accordingly and sealing gas must be
used.

–If the pump is to be operated with more than 50% of the

permissible gas load, sealing gas must be used.

– The turbopump must be connected to a backing pump in

accordance with Section 3.3.

–Only Pfeiffer Vacuum power units may be used to operate

the
TC 600. The use of other power units requires the prior
agreement of the manufacturer and equalisation with the
valid specification.

3.1. Preparations For Installation

Do not carry out any unauthorised conversions
or alterations to the turbopump.

–Pumps must be filled with lubricant befor being operated

(please refer to Section 4.1.).
–The turbopumps must

nnoott

be transported when filled with

lubricant.
–If the turbopump is to be operated with the DCU, the

remote plug 8d on the TC should be disconnected (please

see Section 2.1.) and then proceed in accordance with

Operating Instructions ”Pumping Operations With The

DCU”, PM 800 547 BN.
–The maximum permissible rotor temperature of the pump is

120 °C. If the vacuum chamber or parts in the vacuum

chamber are heated, the values stated in the technical

data relating to the level of heat which may be radiated

into the pump must not be exeeded. If necessary, suitable

shielding must be fitted in the vacuum chamber before the

turbopump (constructional suggestions available on

request).
–Only remove the blank flange from the high and for-

vacuum side immediately before connection.
– Where magnetic fields of > 3 mT are involved suitable

shielding must be provided (available on request).
–If the pump is baked out, the heating sleeve and the body

of the pump must be insulated to prevent burns from

accidental contact.
–In the event of a sudden standstill of the rotor, torques of

up to 8270 Nm can arise and these must be taken up by the

turbopump and frame. Pumps must be anchored as

follows:

–ISO flange with 8 bracket screws,or

–CF flange with the complete set of M8 screws,or

–underside of the pump with 4 screws M8,

screws quality 8.8.

WARNING

3.2. Installing The Pump,
Connecting The High Vacuum Side

The utmost cleanliness must be observed
when fitting all high vacuum parts. Unclean
components prolong the pumping time.

Use a splinter shield

The use of a splinter shield (please see ”Accessories”) in the
high vacuum flange protects the turbopump against foreign
bodies coming from the vacuum chamber but does reduce
the volume flow rate of the pump by approximately 15%. For
fitting splinter shields please refer to “Fitting the splinter
shield”.

The high vacuum side can be flanged onto the vacuum
chamber either directly or via a Pfeiffer Vacuum bellows or a
vibration compensator (please see ”Accessories”).

Connecting via bellows

If the high vacuum side is to be flanged via a bellows, the
turbopump must be secured for example via the holes on the
underside of the turbopump (please see dimensions). The
fastening must be able to withstand the torque referred to in
Section 3.1.

Connecting via a Pfeiffer Vacuum vibration compensator

The maximum permissible temperature at the

vibration compensator is 100 °C.

Where a Pfeiffer Vacuum vibration compensator is in use, a
freely suspended turbopump can be flanged onto the vacuum
chamber. Additional protective casing must be provided to

4. Operations

4.1. Filling In The Lubricant

Pumps must be filled with lubricant before being
operated.
If possible fill in the lubricant in the fitting
position of the pump.

Pumps are designed to operate with Lubricant “F3” contained
with the delivery 65 cm3(see rating plate).

If “F3” is heated above 300 °C, toxic vapours

which can harm the airways are given off. Do
not allow “F3” to come into contact with
tobacco products (danger of poisoning when
ignited). The precautions necessary in the
handling of chemicals must be observed.

Filling in the lubricant

➡ Unscrew lubricant filler screw 71 and, using the syringe A

provided, inject maximum 65 cm3 of lubricant.

If the pump is be operated in the vertical
position, the sight glass should be half full with
lubricant.
If the pump is be operated in the horizontal
position, (fore-vacuum flange pointing down),
the sight glass should be filled with lubricant
up to the upper edge.

☞

PLEASE NOTE

WARNING

CAUTION

f the turbopump is to be installed horizontally in movable
system parts (for example, doors), such parts must be moved
gently.

Where intense acceleration is involved, the

lubricant can permeate the fore-vacuum
chamber and cause contamination.

4.2. Before Switching ON

Sections 4.2 to 4.6. refer only to operating the pump in its
condition on delivery, without the DCU operatimg unit. The
bridges ”venting release”, ”motor, TMP ON” and ”pumping
station ON” are fitted in the remote control plug.

Please refer to Section 4.8. regarding the switching on with
the Operating And Display Control Unit DCU.

Turbopump rotors rotate at high speed. When

the high vacuum flange is open there is a
danger of injury and of damage to the pump
caused by objects falling into the pump.
Therefore never operate the pump with open
high vacuum flange.

➡ With sealing gas: Open the sealing gas supply.
➡ With water cooling: Open cooling water supply and

check flow.

➡ Plug connecting cable 8a (”Accessory”) into the TC 600

and connect with Power Unit TPS 600 on X2 (please see
Section 3.8.).

Please note:

The following pre-settings have been programmed:

– Start-up time 8 min
– Rotation speed switchpoint 80%

– Automatic venting 50%
These settings can only be altered via Serial Interface RS 485
(DCU or PC); please refer to the respective operating
instructions.

➡ Screw back in lubricant filler screw 71 with the O-ring 75.

Where high level gas loads and rotation speeds are involved,
the resulting friction subjects the rotor to the effect of great
heat. To avoid over-heating, a power rotation speed
characteristic line is implemented in the TC 600; this ensures
that where maximum gas loads are involved, the pump will
operate at any rotation speed without the danger of damage
arising.
The maximum power is dependent on the type of gas. Two
characteristic lines are available for any type of gas in order
to fully exploit the power potential of the pump:

–"Gas-Mode 0" for gases with molecular mass 40 as, for

example, Argon;

–"Gas-Mode 1" for all lighter gases.

Works setting: ”Gas-Mode 0”

➡ Set the applicable gas mode on the TC 600 via the DCU

(please refer to Operating Instructions ”Pumping
operations with the DCU” PM 800 547 BN).

Pumping gases with molecular mass 40 with
the incorrect gas mode can cause damage to
the pump.

For the vertex of the power characteristic line please refer to
Section 8. Technical Data.

Maximum power is applied when the pump starts in order to
limit the time required. Once the set rotation speed is
attained, switching to the selected power characteristic line
is automatic.
If the gas dependent maximum power is exceeded, the
rotation speed is reduced until equilibrium between the
permissible power and gas friction is attained. The power
limitation serves to protect the pump against thermal
over-loading. In order to avoid rotation speed fluctuations it is
recommended to set, in rotation speed setting mode, the
equilibrium frequency or a somewhat lower frequency.

There can be types of pump whereby there is
no differentiation between the two ”gas
modes” settings.

When the unit is switched on for the first time
or after a lubricant change the contact to the
lubricating pump can open as a result of the
degassification of the lubricant. In such cases,
as for other malfunctions, the electronic drive
unit shuts down the turbopump.

➡ The turbopump must be re-started with switch S1 on the

power unit.

Take care when pumping hazardous gases and
observe the safety precautions of the gas
manufacturer.

4.4. Gas Type Dependent Operations

Water cooling is required if the pumps are to be

operated with gas load.

CAUTION

WARNING

☞

PLEASE NOTE

4.5. Circulatory Lubrication

The ball bearing on the fore-vacuum side is supplied with
lubricant via the lubricating pump.
The circulation of the lubricant is monitored via a switching
contact. If there is insufficient lubricant, the electronic drive
unit switches off the turbopump. Monitoring is active only
from 60% of the final rotation speed.
If, at a rotation speed of > 60% of the final rotation speed (for
example through the degassification of the lubricant), the
contact opens for 2 minutes, the electronic drive unit
assumes a lubricant deficiency and switches off the
turbopump.

➡ Check the filling level of the lubricant.
➡ Re-start the turbopump with switch S1 on the power unit.

4.6. Switching OFF And Venting

To avoid contamination occurring when switching off, the
pump should be vented before shut-down.

➡ Switch off both turbopump and backing pump on the

power unit at the same time with switch S1.
Where corrosive gas processes are involved, the sealing
gas supply should be shut off after approximately 10 minu­tes and both turbo pump and backing pump switched off
with switch S1.

➡ Venting

There are three possibilities to vent turbopump:
–

MMaannuuaall vveennttiinngg

with the use of the venting screw

(status on delivery).

–

VVeennttiinngg wwiitthh tthhee vveennttiinngg vvaallvvee

which is selectable via
the remote control (please see Section 4.9.), or via the
DCU (see Operating Instructions, "Pumping Operations
With The DCU", PM 800 547 BN).

–

VVeennttiinngg iinn ttwwoo ssttaaggeess

when the vacuum chamber
should be vented as quickly as possible. First stage:
venting with a pressure increase rate of 15 mbar/s for
20 seconds. Second stage: venting with an optionally
large venting valve.

The valve cross-section for a venting rate of 15 mbar/s
must be compatible with the size of the vacuum chamber.
Where small vacuum chambers are involved, the
Pfeiffer Vacuum Venting Valve TVF 005 can be used for
first
stage venting.

➡ Shut off water supply.

4.7. Shutting Down For Longer Periods

Vacuum pumps are sometimes used to pump

aggressive or hazardous gases. There is a
danger of personal injury resulting from coming
into contact with process gases. Before
removing a turbopump from the system, first:

–Vent the turbopump with a neutral gas or dry air.
–Ensure that there is no residual process gas in the system

nor in the feeder lines.

WARNING

If the turbopump is to be shut down for more than a year:

➡ Remove turbopump from the system.
➡ Change the lubricant (see Section 7.1.).
➡ Close the high vacuum flange and evacuate the turbopump

via the fore-vacuum flange.

➡ Vent turbopump via the venting connection with nitrogen

or dry air.

➡ Close fore-vacuum and venting connection by blank

flanging.

➡ Place the pump vertically on its rubber feet.
➡ In rooms with moist or aggressive atmospheres, the

turbopump must be air-sealed in a plastic bag together
with a bag of dessicant, e.g silicagel.

If the pump has been shut down for

33 yyeeaarrss

a
bearing change must be carried out (please
get in touch with Pfeiffer Vacuum Service).

4.8. Operations With The DCU 001 / DCU 600

Operations with the DCU 001 or DCU 600 should be carried out
in accordance with the relevant Operating Instructions
PM 800 477 BN (DCU description) and PM 800 547 BN
(operating the pump with the DCU).

Operations with the DCU 001/DCU 600, the
remote plug 8d on the TC should be
disconnected (please see Section 2.1.).

4.9. Operations With The Remote Control Unit

(please refer to the table in Section 3.10.).
Remote control operations can be performed via the
connection with the designation “REMOTE” on the TC 600.
The connection is via a 10 pole screwed connector plug with
the following arrangement:
1- + 24V

Rotation Speed Setting Operations

Via Input PWM

The supply of pulse width modulated signals (PWM) with a
ground frequency of 100 Hz ±20% with an amplitude of
maximum 24 V and a touch ratio of 25-75% enables the
rotation speed to be set in the range from 20-100% of the
nominal rotation speed.

Venting Release (Optional)

Automatic venting:

When the turbopump or pumping station is switched off the
venting valve opens for the venting time of 3600 seconds
(1 hour) when the venting frequency falls below 50% of the
final rotation speed (330 Hz). In the event of a mains power
failure if the venting frequency falls below 50% of the final
rotation speed the venting valve opens and closes on
attainment of 15% of the final rotation speed.

Venting OFF:

Venting does not take place.

Other venting modes:

Other venting modes can be selected via the DCU.

Motor, Turbopump

When the pumping station is switched on and once the self
test has been successfully completed (duration approximate­ly 20 seconds), the turbopump is set in operation.
During operations, the turbopump can be switched on and off
while the pumping station is switched on.

Pumping Station

Any connected pumping station components are started up
(e.g. backing pump, venting valve, air cooling) and with
simultaneous activation of the input ”motor, turbopump” the
turbopump is set in operation once the self test has been
successfully completed (duration approximately 20 seconds).

Heating/Reset

Heating (optional)

Once the rotation speed switchpoint is attained the heating
unit is switched on; when the rotation speed switchpoint is
fallen below the heating unit is switched off.

Reset

The heating input has two functions (please refer to the table
in Section 3.10., point 5 ”Reset”).

Standby

The pump can be operated optionally at 66% of its nominal
rotation speed (standby ON) or at its nominal rotation speed
(standby OFF).

If no signal is present the pump runs up to its final rotation
speed.

Available as accessories:

–A PWM adapter box for rotation speed setting operations

for the turbopump.

–A Brake Unit TBU 600 which enables, in rotation speed

setting mode, faster braking on turbopumps.

Switching Outputs

Switching outputs 1 and 2 can be loaded with a maximum
24 V / 50 mA per output. The following functions are assigned
to the switching outputs:

SSwwiittcchhiinngg oouuttppuutt 11::

Active high when the rotation speed
switchpoint is attained. The switchpoint
for the turbopump is set at 80% of the
nominal rotation speed. It can be used,
for example, for a message ”pump
ready to operate”.

SSwwiittcchhiinngg oouuttppuutt 22::

Active low with a collective malfunction
message (see Section 6.).

The connection of a relay is made between pin 10 (mass) and
the respective switching output pin 8 or pin 9 (see Section

3.13. Connections Diagram).

5. Monitoring Operations

5.1. Operations Display Via LED

Certain operations modes of the turbopump and the TC 600
can be ascertained via the two integrated LEDs located on
the front panel of the TC 600.
The following operations modes are displayed:

5.2. Turbopump Temperature Monitoring

Where impermissible motor temperatures are involved or the
temperature of the TC 600 casing is too high, the motor
current is reduced. This can lead to dipping below the set
rotation speed switchpoint and results in the turbomolecular
pump being switched off.

LED on the TC 600 glows red: Collective malfunction.

are available to you to ensure any system down time is kept
to a minimum:
–Have the pump repaired on the spot by our Pfeiffer

Vacuum Service Engineers;
–Return the pump to the manufacturer for repairs;
– Replace the pump.

Local Pfeiffer Vacuum representatives can provide full
details.

Please take into account that where Pfeiffer

Vacuum Service replacement service is
involved the standard operating parameters are
always
pre-set.
If your application requires different

parameters, please modify accordingly.

The turbopump and the Electronic Drive Unit
TC form a single unit and must therefore be
returned complete for repair purposes. Before
returning the unit it should be ensured that the
power unit is not the cause of the malfunction
(please see Section 5. for checking the power
unit).

Before returning:

➡ Detach all accessories.
➡ Please attach a clearly visible notice "Free of harmful

substances" (both on the unit and also on the delivery note

and any accompanying letters).
"Harmful substances" are substances and preparations as
defined in the current, local, dangerous substances
regulations; in the U.S.A. as" materials in accordance with the
Code of Federal Regulations (CFR) 49 Part 173.240 Definition
and Preparation". We will carry out the decontamination and
invoice this work to you if you have not attached this note.
This also applies where the operator does not have the
facilities to carry out the decontamination work.

9.1. Dimensions Diagram

1) Measured with a rotary vane vacuum pump > 5m3/h,
higher gas throughputs with reduced rotation speed.

2) In TMS operations the maximum gas throughput is reduced with increasing TMS temperature.

3) If the pump is to be operated with more than 50% of the maximum gas load, sealing gas must
be used.

4) For gas type characteristics lines please refer to Section 4.4.
Where pumps for TMS operations are involved, the corner points reduce according to the
temperature; the values are available on request.

5) In accordance with DIN 28 428 the final pressure of a turbomolecular pump is that pressure
which is attained in a measuring dome 48 hours after baking out.

6) See rating plate.

7) With maximum gas throughput.

8) Protection class IP 54 is afforded for the Electronic Drive Unit TC 600 by retro-fitting a cover
plate (accessory).
