2.1 Safety precautions

Duty to inform

Each person involved in the installation or operation of the unit must read and observe
the safety-related parts of these operating instuctions.

 The operator is obligated to make operating personnel aware of dangers originating

from the unit or the entire system.

Danger of unsafe electrical installation

Safe operation after installation is the responsibility of the operator.

 Do not independently modify or change the pump and electrical equipment.
 Make sure that the system is integrated in an emergency off safety circuit.
 Consult Pfeiffer Vacuum for special requirements.

Danger of electric shock

In case of defect, the parts connected to the mains supply are under voltage.

 Always keep the mains connection freely accessible so that you can disconnect it at

any time.

Safety

WARNING

WARNING

WARNING

Automatic start-up after power failure or malfunction acknowledgement

The function "pumping station" of the electronic drive unit remains active after power
failure or errors that lead to shut down the pump or the system. The turbopump runs up
automatically after power ist restored or malfunction acknowledgement.

 Switch off the function "pumping station" if necessary.
 Provide safety measures against interference in the high vacuum flange while the tur-

bopump is running.

CAUTION

Automatic start

After bridging the contacts Pin 1, 3, 4 on the connection "REMOTE" and setting up the
supply voltage, the turbopump will run up immediately.

 Switch on the mains supply on the turbopump immediately before operation.

NOTICE

Damages to the pump and drive

Even after the mains power is switched off, the subsequently running pump delivers
electric power to the electronic drive unit. There is a danger of electric body contact by
premature separating the pump from the electronic drive unit.

 Never separate the electronic drive unit from the pump when the mains power is con-

nected or the rotor is running.

● Observe all safety and accident prevention regulations.

● Always ensure a safe connection to the protective earthing conductor (PE, protection

class I).

● Regularly check the proper observance of all safety measures.

● Before carrying out any work disconnect the unit and all associated installations safely

from the mains.

● Do not loosen any plug connection during operations.

Safety

2.2 Proper use

● The unit has been accredited with protection class IP 20. Take necessary measures

when installing into ambient conditions, which afford other protection classes.

● Use as a desktop unit is only possible with a suitable cover.

● Observe fire protection specifications according IEC 61010 when installing in hous-

ings.

● Keep leads and cables well away from hot surfaces (> 70 °C).

● Only separate the pump and the electronic drive unit from each other after disconnect-

ing the supply voltage and the complete standstill of the pump.

NOTICE

EC conformity

The manufacturer's declaration of conformity becomes invalid if the operator modifies
the original product or installs additional components.

AI Rotation speed setting mode / Pin 7 and Pin 26

The analog input defines the set rotation speed of the turbopump. An input signal of 2 ­10 V between AI+ (Pin 7) and GND (Pin 26) corresponds to a rotation speed within the
range of 20 - 100% of the nominal rotation speed. If the input is open or signals fall below
2 V, the pump is accelerated up to nominal rotation speed.

U(V)

5.8.4 Outputs

5.8.5 Relay contacts

The digital outputs on the "REMOTE" connection can handle a max. load of 50 mA per
output. Some outputs are configurable with the Pfeiffer Vacuum parameter set via the
RS-485 interface (description relates to factory settings).

DO1 (Rotation speed switchpoint attained) / Pin 8

Active high after the rotation speed switchpoint is attained. Rotation speed switchpoint 1
is factory-set to 80% of the nominal rotation speed. It can, for example, be used for a
"pump operational" message.

DO2 (No errors) / Pin 9

When the supply voltage has been established, digital output DO2 permanently outputs
24 V DC which means "no errors". Active low in case of error (collective error message).

AO analog output 0-10 V DC / Pin 12

● 0 - 10 V DC is equivalent to 0 - 100 % x f

Nominal

A voltage Vf can be tapped via the analog output; it is proportional to the turbopump
speed (load R ≥ 10 kΩ). Alternatively, either the current (V

) or output (Vp) can be as-

i

signed via keypad input or interface.

20

Relay 1 / Pin 15, 16 and 17

The contact between pin 16 and pin 15 is closed if the speed switching point is reached
or exceeded - relay 1 is active. The contact between pin 16 and pin 17 is closed if the
speed switching point is not reached or undershot - relay 1 is inactive. Relay control fol­lows digital output pin 8.

Relay 2 / Pin 18, 19 and 20

The contact between pin 19 and pin 18 is closed in case of trouble-free operation - relay
2 is active. The contact between pin 19 and pin 20 is closed if an error has occurred ­relay 2 is inactive. Relay control follows digital output pin 9.

7.5 Operation

All function-relevant variables of a turbopump are anchored in the electronic drive unit as
parameters. Each parameter has a three-digit number and a designation. Parameters
can be used via Pfeiffer Vacuum display and control units or via RS-485 with the Pfeiffer
Vacuum protocol.

The value of a parameter is always readable. Editable parameters are adjustment com­mands and target values (See the operating instructions for the respective electronic
drive unit for this purpose).

7.5.1 Selecting the parameters

 Preselect parameter number using the (backwards) or (forwards) keys.

– Fast scrolling by pressing and keeping the relevant key depressed.

● The selected parameter appears in line 1, the corresponding value in line 2.

7.5.2 Set parameters

Start pump by pressing "Pumping station ON/OFF" key

The "Pumping station" key only controls the parameter [P:010]. All components con­nected via the electronic drive unit will be activated or deactivated according to their
configuration.

 Ensure that the parameter [P:023] is also switched on for powering-up the tur-

bopump.

Operation with the Pfeiffer Vacuum parameter set

8 Operation with the Pfeiffer Vacuum parameter set

8.1 General

8.1.1 Factory settings

The electronic drive unit is pre-programmed in the factory. This guarantees proper, reli­able turbopump operation without the need for additional configuration.

 Restore factory settings via parameter [P:095] if necessary.

– Attention! All customized settings will be lost.

8.1.2 Checking the adjustments

 Before operating with parameters, check set values and control commands for their

suitability for the pumping process.

 Remove the remote plug from electronic drive unit if required.

8.1.3 Keypad lock

The control keys on the front of the electronic drive unit can be locked against unautho­rised use.

 Locking of the keypad via parameter [P:008].

– All of the keypad input functions are disabled.
– It is still possible to scroll through the parameter list.

 The keypad can only be unlocked by:

– Interfaces RS485/RS232
– De-energising through power OFF. The connected pump must run down complete-

ly to idle (f = 0).

8.2 Rotation speed set value

The typical nominal rotation speed of a turbopump is factory-set in the electronic drive
unit. If the electronic drive unit is replaced or a different pump type is used, the reference
set value of the nominal rotation speed must be confirmed. This procedure is part of a
redundant safety system for avoiding excess rotation speeds.

 Adjust the parameter [P:777] according to the pump type.

Once the nominal rotation speed is attained, the pump will run idle unless additional gas
loads are entered. Depending on process or application requirements, the nominal rota­tion speed can be reduced in rotation speed setting mode or standby mode.

Operation with the Pfeiffer Vacuum parameter set

8.3 Remote control

There are basically three remote control options with different priorities. The advantage
of the remote control feature is the ability to connect multiple electronic drive units via
"REMOTE".

8.3.1 Standard operation

Standard operation generally means operation via TCP 350 keypad without explicit pri­oritisation of user interfaces. Beyond this, controls and functions are supported via the
RS-485 interface. Similarly, the switching functions of the "REMOTE" connection are
available if connected.

 Parameter [P:028] = 0

● Exception: Connecting pin 14 on REMOTE with +24 V DC assigns priority to the

functions on this connection and locks them for the other interfaces.

8.3.2 REMOTE Priority ON

Connection "REMOTE" on the electronic drive unit has priority over all the functions of
the other interfaces.

 Parameter [P:028] = 1
 Pin 14 = active High

● Exception: Error acknowledgement is still possible via the corresponding key.

8.3.3 REMOTE Priority OFF

Connection "REMOTE" on the electronic drive unit does not have priority over the func­tions of the other interfaces.

 Parameter [P:028] = 1
 Pin 14 = active low

● Exception: Error acknowledgement is not possible via pin 13 until pin 14 "active high"

again.

8.4 Gas type dependent operations

Danger of the pump being destroyed

Pumping of gases with a higher molecular mass in the wrong gas mode can lead to de­struction of the pump.

 Ensure the gas mode is correctly set.
 Contact Pfeiffer Vacuum before using gases with a greater molecular mass (> 80).

Friction causes the rotor to heat up severely under gas load and high rotation speed. To
avoid overheating, the electronic drive unit has implemented power-rotation speed-char­acteristics, whereby the pump can be operated at every rotation speed with the maxi­mum allowable gas load without danger of damage. The maximum power consumption
depends on the gas type. Three characteristics are available in order to completely ex­haust the pump's capacity for each gas type.

NOTICE

● Gas mode "0" for gases with the molecular mass >39, e.g. argon.

● Gas mode "1" for gases with the molecular mass  39.

● Power characteristics according to the technical data of the turbopump.

 Check and set-up the gas mode via [P:027].

C-D = Gas mode "0"

Fig. 7: Principle of power characteristics lines for gas type dependent operations,

e.g. gas mode = 0

The turbopump runs up with maximum power consumption. When the nominal and/or set
rotation speed is reached, the pump automatically switches over to the chosen power
characteristic of the selected gas mode. Increasing gas load is initially compensated by
a rise in power consumption in order to keep the rotation speed constant. Increasing gas
friction, however, causes the turbopump to heat up more severely. When the gastype­dependent maximum power is exceeded, the rotation speed of the turbopump is reduced
until an equilibrium between permissible power and gas friction is attained.

 To avoid rotation speed fluctuations, Pfeiffer Vacuum recommends setting a some-

what lower frequency in rotation speed setting mode.

8.5 Run-up time

The run-up of the turbopump is time-monitored ex factory. There are various causes of
prolonged run-up times, e.g.:

● Too high gas loads

● Leakage in the system

● The set value run-up time is too low

 Eliminate any external and application-related causes.
 Adjust the run-up time via parameter [P:700].

8.6 Adjusting the rotation speed switchpoint

The rotation speed switchpoint can be used for the message "Pump operational for the
process". Overrunning or underrunning the active rotation speed switchpoint activates or
deactivates a signal at the pre-configured output on the electronic drive unit and at the
status parameter [P:302].

 Adjust the parameter [P:701] to the desired value in %.

Signal output and status parameter [P:302] are based on the set value for rotation speed
switchpoint 1 [P:701].

8.7 Rotation speed setting mode

The rotation speed setting mode reduces the rotation speed and hence the throughput
of the turbopump. The pumping speed of the turbopump changes proportional to rotation
speed. Standby mode is ineffective during rotation speed setting mode. The set rotation
speed is adjusted by the set value in rotation speed setting mode [P:707]. The rotation
speed switchpoint varies with the set rotation speed. Underrunning or overrunning the
set value in rotation speed setting mode activates and deactivates the status signal
[P:306] * respectively.

31

Operation with the Pfeiffer Vacuum parameter set

*  Adjust the parameter [P:707] to the desired value in %.

 Parameter [P:026] = 1
 Query parameters [P:308] .

8.8 Standby

Pfeiffer Vacuum recommends standby mode for the turbopump during process and pro­duction stops. When standby mode is active, the electronic drive unit reduces the rotation
speed of the turbopump. Standby mode is ineffective during rotation speed setting mode.
The factory setting for the set value in standby mode is 66.7 % of the nominal rotation
speed. Underrunning or overrunning the set speed in standby mode activates or deacti­vates the status signal [P:306] *.

*  Adjust the parameter [P:717] to the desired value in %.

 Parameter [P:026] = 0
 Parameter [P:002] = 1
 Query parameters [P:308] .

8.9 Operation mode backing pump

Operation of a connected backing pump via the electronic drive unit depends on the
backing pump type.

 Connect the control lead of the relay box to the "remote" connection of the electronic

drive unit using an adapter cable.

 Adjust the parameter [P:025] to the desired value.

8.9.1 Continous operation

At the same time as "Pumping station on" the electronic drive unit sends a signal to the
pin 11 to switch on the backing pump. This signal can also be used to control a fore­vacuum safety valve.

8.9.2 Intermittend operation (diaphragm pumps only)

Intermittend operation can extend the life expectancy of the membrane of a connected
diaphragm pump. Either a diaphragm pump with built-in semiconductor relay or an inter­connected relay box with semiconductor relay is required for intermittend operation. The
backing pump is switched on and off in dependence of the turbopump's power consump­tion. A relation to the supplied fore-vacuum pressure is derived from the power consump­tion. The switching off and switching on thresholds for the backing pump are adjustable.
Fluctuations in the power consumption of idling turbopumps and type-dependent varying
fore-vacuum pressures of the backing pumps require the switching thresholds to be set
separately for the intermittend mode.

Pfeiffer Vacuum recommends the intermittend mode between 5 and 10 hPa. A pressure
gauge and a dosing valve are required to set the switching thresholds.

 Switch on the vacuum system via the function "pumping station" and await the run-up.
 Generate a fore-vacuum pressure of 10 hPa by gas inlet via dosing valve.
 Read and note the parameter [P:316].
 Adjust the switch on threshold backing pump via parameter [P:711] to the determined

drive power for a fore-vacuum pressure of 10 hPa.

 Reduce the fore-vacuum pressure to 5 hPa.
 Read and note the parameter [P:316].
 Adjust the switch off threshold backing pump via parameter [P:710] to the determined

drive power for a fore-vacuum pressure of 5 hPa.

32

8.10 Operation with accessories

Depending on the configuration, various accessories can be connected to the turbopump
and controlled via parameter of the electronic drive unit.

Operation with the Pfeiffer Vacuum parameter set

33

Operation with the Pfeiffer Vacuum parameter set

8.10.1 Air cooling/heating

 It is necessary to select the accessory device via parameters [P:035].
 Display of the selected accessory via parameters [P:335].

If air cooling is connected, it is immediately activated after switching on the pumping sta­tion with parameter [P:010].

The ability to operate a connected housing heater depends on the rotation speed switch­point via parameter [P:701].

 Switch heating on or off with parameter [P:001].

Exceeding or dropping below the rotation speed switchpoint controls the operation of the
housing heater. The operating condition is represented by the symbol in the LCD display.

8.10.2 Vent modes

The turbopump can be vented only after the function "pumping station" has been
switched off. Signals are sent to configured outputs with a fixed delay of 6 s. There are
three options for operation with a venting valve connected.

 Enable venting via parameter [P:012].
 Select the venting mode via parameter [P:030].

Delayed venting

Start and venting time after "pumping station off" are configurable and depend on the ro­tation speed of the turbopump.

 Parameter [P:030] = 0
 Adjust the venting rotation speed in % of the nominal rotation speed via parameter

[P:720].

 Adjust the venting time in s via parameter [P:721].

If the venting rotation speed is underrun, the venting valve will open for the set venting
time. In the event of a power failure, venting will occur if the set venting rotation speed is
underrun. In this case, the venting period depends on the residual energy delivered by
the moving rotor. When power is restored, the venting process is interrupted.

No venting

No venting is performed during this operation mode.

 Parameter [P:030] = 1

Direct venting

Start and venting time are not configurable. Venting starts with a delay of 6 s after "pump­ing station off". When the function "pumping station" is switched on renewed, the venting
valve closes automatically. In the event of a power failure, venting will occur if an an­chored type-specific rotation speed is underrun. When power is restored, the venting
process is interrupted.

34

 Parameter [P:030] = 2

8.11 Pressure measurement

Pressure measurement with the TCP

An exact pressure measurement is not possible with the TCP. This is particularly true
with linear gauges in the lower pressure range.

 Use suitable measuring instrument.

8.11.1 Displaying the gauge type

 Select or enter parameter [P:738] Gaugetype.

Gauges with identical surge impedance are only recognized as a group (e.g. CMR?).
Manual input of the exact gauge type is also possible via the parameter [P:738].

8.12 Monitoring the thermal load

If threshold values are overrun, output signals from temperature sensors allow the pump
to be brought to a safe condition. Depending on pump type, temperature threshold val­ues for warnings and error messages are saved fixed in the electronic drive unit . For
information purposes, various status queries are prepared in the parameter set.

35

Operation with the Pfeiffer Vacuum parameter set

8.13 Switching on/off the pump

Start pump by pressing "Pumping station ON/OFF" key

The "Pumping station" key only controls the parameter [P:010]. All components con­nected via the electronic drive unit will be activated or deactivated according to their
configuration.

 Ensure that the parameter [P:023] is also switched on for powering-up the tur-

bopump.

8.13.1 Switching on

The function "pumping station" comprises turbopump operation with control of all con­nected accessories (e.g. backing pump).

 Parameter [P:023] = 1
 Parameter [P:010] = 1

After successfully completing a self-test, the electronic drive unit switches on the tur­bopump motor and all connected accessories as per their configuration.

When the pumping station is activated, the motor of the turbopump can be switched off
and on via the function [P:023].

8.13.2 Switching off

 Parameter [P:010] = 0

The electronic drive unit switches off the turbopump and activates preset accessory op­tions (e.g. venting ON, backing pump OFF).

10 Malfunctions

10.1 General

Turbopump and electronic drive unit malfunctions always result in a warning or error
message. In both cases, the electronic drive unit outputs an error code. Operating mes­sages are generally displayed via the LEDs on the electronic drive unit. If an error occurs,
the turbopump and connected devices will be switched off. The selected venting mode
will be triggered after the preset delay.

Automatic start-up after power failure or malfunction acknowledgement

The function "pumping station" of the electronic drive unit remains active after power
failure or errors that lead to shut down the pump or the system. The turbopump runs up
automatically after power ist restored or malfunction acknowledgement.

 Switch off the function "pumping station" if necessary.
 Provide safety measures against interference in the high vacuum flange while the tur-

bopump is running.

10.2 Operation display via LED

Malfunctions

WARNING

10.2.1 Operation display via LED

The red LED (error status) and green LED (operating status) on the front panel of the
TCP show the following states:

LED Symbol LED status Display Meaning

Green Off currentless

Red Off no malfunction, no warning

10.3 Error codes

Errors (** Error –––– **) always cause the connected peripheral devices to be switched
off.

 Eliminate error and reset by pressing key .

Warnings (* Warning –––– *) are only displayed and do not cause components to be
switched off.
