2.1 Safety precautions
●Power supply: The turbopump power supply must apply to the requirements of dou-
ble insulation between mains input voltage and operating voltage according to the reg-
ulations of IEC 61010 and IEC 60950. Therefore Pfeiffer Vacuum recommends to use
exclusively original-power packs and -accessories. Only in this case Pfeiffer Vacuum
is able to guarantee the compliance of the European and North American guidelines.
●Observe all safety and accident prevention regulations.
●A safe connection to the protective earthing conductor (PE) is recommended (protec-
tion class III).
●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.
●The unit has been accredited with protection class IP 54. Take necessary measures
when installing into ambient conditions, which afford other protection classes.
●The protection class IP 54 is only attained by correctly placed rubber stoppers on the
address selection switches.
●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.
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.
WARNING
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.
WARNING
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.

2.2 Proper use
●The electronic drive unit TC 400 DN operates designated Pfeiffer Vacuum turbopumps
and their accessories in a DeviceNet bus system.
2.3 Improper use
Improper use will cause all claims for liability and warranties to be forfeited. Improper use
is defined as usage for purposes deviating from those mentioned above, especially:
●use of accessories or spare parts, which are not named in this manual
●operation of the devices in areas with ionizing radiation
2.4 Functional safety
The drive unit (electronic drive unit) TC 400 DN performs the safety function "Safe Lim-
ited Speed" according to EN 61800-5-2. In case of excess rotation speed the commuta-
tion of the pump motor is switched off and the drive transferred into the safe condition.
Summary of characteristic data for use in safety-relevant applications:
●During the expected device life span of up to 20 years no proof test is required.
●If the user calculates his safety application with the specified values for 20 years, the
safety control system must be taken out of operation after 20 years and returned to
the manufacturer. A proof test cannot be accomplished by the user.
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 accord-
ingly.
warranty seal
Closure seal
The product is sealed at the factory. Damaging or removal of a closure seal leads to the
loss of liability and warranty entitlements.
Do not open the product within its warranty period!
For process-related shorter maintenance intervals please contact the Pfeiffer Vacu-
um Service.

5 Connection "DeviceNet"
5.1 Connections
The turbopump can be connected to a DeviceNet bus system using the connector (5 -
pin, sealed micro) labelled "DeviceNet" on the electronic drive unit. A supply voltage (V+,
V-) is required to supply this connection in addition to the supply voltage for the electronic
drive unit. The interface is galvanically safe and is isolated from the maximum supply
voltage for the electronic drive unit.
Perform DeviceNet wiring in accordance with the applicable specifications.
Supply the DeviceNet connection with voltage.
5.2 Configuring the connection
To start DeviceNet communication, the unit can be configured using the appropriate EDS
files.
Select desired device address
Select desired baud rate
Fit rubber plugs at the address selector switches evenly and as deep as possible to
achieve the stated protection class.
5.2.1 Device address
The DeviceNet device address is set manually using the "ADDRESS" selector switches
or via DeviceNet.
Setting the address manually
Set the selector switches to the desired value.
– Once the setting has been made, the device accesses the bus using the new ad-
dress.
Setting the address via DeviceNet
Switch off the unit or disconnect it from the mains supply.
Set the selector switches to "P".
– When switched on, the system uses the last valid address ("63" upon delivery).
– The address is programmable via DeviceNet object 3.1.1. (see p. 14, chap. 5.5).

Connection "DeviceNet"
5.2.2 Baud rate
The DeviceNet baud rate is set manually using the "RATE" selector switches or via De-
viceNet.
Setting the baud rate manually
Set the selector switches to the desired value.
– The change takes effect the next time the system is switched on.
Setting the baud rate via DeviceNet
Switch off the unit or disconnect it from the mains supply.
Set the selector switches to "P".
– When switched on, the system uses the last valid baud rate (500 kBit/s upon deliv-
ery).
– The baud rate is programmable via DeviceNet object 3.1.2. (see p. 14, chap. 5.5).
5.3 Configuring the data exchange
Depending on the program used to set up DeviceNet communication, you can carry out
the following steps:
Import EDS file (see scope of delivery)
Device-specific data:
Specify the format of the cyclical input/output data
– Specify the cyclically alternating process data using objects "Poll I/O input data
(4.0.100)" and "Poll I/O output data (4.0.101)"
– The format can be changed only if the poll I/O connection is inactive.
Specify system behaviour following termination of the cyclical DeviceNet communica-
tion.
– Use object "Idle Action (9.1.7)" to specify which action is to be carried out if there
is a failure of the cyclical exchange of process data (poll I/O connection).
Specify the remote priority.
– Use object "Permission locked (101.0.17)" to specify whether the electronic drive
unit is to be controlled exclusively via DeviceNet or whether other interfaces (e.g.
RS485) are also permitted.
– This does not restrict write access via other interfaces.
Perform pump configuration.
– To set a configuration that differs from the delivery state, use the EDS file to adjust
individual objects (e.g. accessory configuration).
Master-specific data:
Set up the device in the master scanlist.
Set the format of the cyclical input/output data
5.3.1 Explicit data exchange (explicit connection)
This connection can be used to access the individual DeviceNet objects (seep. 14,chap.
5.5). As a rule, this is done using a dedicated configuration program and the EDS file.
This is also used to specify which data is sent during the cyclical data exchange.

5.3.2 Cyclical data exchange (poll I/O connection)
For the cyclical data exchange, multiple DeviceNet objects are combined to form assem-
blies (4.x.3.). One assembly is selected for each direction (input/output data). The follow-
ing assemblies are available for selection:
Input data (produced data, pump --> PLC)
1: pump status (default)
2: pump status, speed
100: pump status, speed, current
101: pump status, speed, current, temperature
