2.1Safety 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
2.2Proper 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.
Following installation into a plant and before commissioning, the operator must check
the entire system for compliance with the valid EU directives and reassess it accordingly.

Remarks to ambient conditions
The specified permissible ambient temperatures apply to operation of the turbopump at
maximum permissible fore-vacuum pressure or at maximum gas throughput depending
on the cooling method. The turbopump is intrinsically safe by a redundant temperature
monitoring.
● By reducing the fore-vacuum pressure or gas throughput, the turbopump can be op-
erated at higher ambient temperatures.
● If the maximum permissible operating temperature of the turbopump is exceeded, the
electronic drive unit reduces drive power first and switches off then, if necessary.

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.

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).

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

Operation with the Pfeiffer Vacuum parameter set
8Operation with the Pfeiffer Vacuum parameter set
8.1General
8.1.1Factory 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.
8.1.2Checking 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.
8.1.3Keypad 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).
8.2Rotation 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.
Pump typeNominal rotation speed, settings for [P:777] in Hz
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".
8.3.1Standard 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.
8.3.2REMOTE 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.
8.3.3REMOTE 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.
8.4Gas 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
30
● 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].

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.
8.5Run-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].
8.6Adjusting 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].
8.7Rotation 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 %.
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 %.
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.
8.9.1Continous 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.
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.

and controlled via parameter of the electronic drive unit.

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.

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.

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).

10Malfunctions
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.
