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

WARNING
WARNING
2.2 Proper use
● Observe the safety and accident prevention regulations.
● Check regularly that all safety precautions are being complied with.
● Do not loosen any plug connection during operations.
● Keep leads and cables well away from hot surfaces (> 70 °C).
● Always ensure a safe connection to the protective earthing conductor (PE, protection
class I).
● The unit has been accredited with protection class IP 20. Take necessary measures
when installing into ambient conditions, which afford other protection classes.
● Before carrying out any work disconnect the unit and all associated installations safely
from the mains.
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.
● The DCU is a display and control unit and may only be used to control Pfeiffer Vacuum
Turbopumps with electronic drive unit and associated peripheral devices.

5.1 Assembly
NOTICE
Ensure free convection
Incorrect installation can cause damage by over-heating or create a fire hazard.
Maintain a minimum distance of 50 mm from cooling vents to adjacent components
or boundaries.
Install the device upright.
Rack installation The unit is fitted in a casing that is suitable for installation in 19"/3HE rack modules.
Insert the unit in the guiderails of a 19"/3HE rack and screw on the front panel secure-
ly with four fixing screws provided as part of the scope of supply.
5.2 Connecting to the mains power supply
This only applies to DCUs with integrated power packs. The DCU 002 receives the
operating voltage via the "RS485" interface for the turbopump electronic drive
unit.
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 you can disconnect it at any
time.
Order the mains cable separately (see "accessories").
Switch off switch S1 on the power pack (position "0").
Plug mains cable into the mains connection "AC in".
Lock the mains cable with the mounting bracket.
Connect the mains cable to the mains.
Always ensure a safe connection to the protective earthing conductor (PE, protection
class I).

Installation
Connect interface cable (supplied) on "RS485" to DCU and electronic drive unit.
Make connection between "DC out" on DCU and "DC in" on electronic drive unit in ac-
cordance with the terminal diagram or with a connecting cable from the Pfeiffer Vacuum accessories.
Connect pressure gauge if required to "X3" on the DCU.
● The RS485 serial interface is used exclusively to control the electronic drive unit on
the vacuum pump. See the Operating Instructions for the respective electronic drive
unit for the interface protocol specification.
Note the operating priority of the interfaces for the electronic drive unit!
DIL switches in the connecting cable or bridges in the mating connector for the D-Sub
connector for the electronic drive unit enable operation of the pump without control unit.
This may cause priority conflicts with the RS485 interface.
Disconnect the mating connector from the "remote" terminal prior to connecting a
DCU to electronic drive units TC 400, TC 1200 or TM 700.
Switch off the supreme operating control (DIL switch S1/S2 = OFF) prior to connect-
ing a DCU to the electronic drive unit TC 110.

Ensure correct connection in the absence of display!
All connecting cables must always be connected to the electronic drive unit and the
mains at DCU with integrated power supplies. Otherwise the correct functioning of the
unit is not possible; there will be no operating display.
Connect all connecting cables for "RS485", "DCout" and "ACin".
Switch on the supply voltage with switch S1 on the DCU with integrated power pack,
or when using a DCU 002 switch on via the provided power pack (e.g. TPS).
Self-test The DCU carries out a self-test and a check of the connected units after switch-on. The
duration of the self-test is approx. 20 s and is visualized in the display with a progress bar.
● LC display test: All characters in the LC display go dark for a short time.
● LED test: The red and green LEDs illuminate during the self-test.
● Hardware test of the DCU DCU
● Pump electronics connection test: The correct pump electronics connection and iden-
tity will be checked.
● Parameter check: Information on operating parameters will be loaded.
● Identification of the connected units: Electronic drive unit designation display.
● If no error has occurred, the DCU is ready to operate.
● The green LED flashes.

6.5 Operation
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).
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.
Set parameters Select a parameter.
Simultaneously press keys and .
● The edit mode for the selected parameter is active.
● At the beginning of the second line an arrow ( –––►) appears.
Using keys , to decrease or increase the value, respective to change op-
tions.
Simultaneously press keys and .
● If line 3 = empty (see P:795), the following will be displayed: "change confirmed"
● The parameter is set.
● Edit mode for the parameter is ended. The arrow ( –––►) disappears.
Edit mode( –––►) will disappear again automatically under the following conditions and without accepting the value to be changed:
● Input disruption or no key operation for more than 10s.

Operation
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.
6.7 Pressure measurement
Connection and use of a high vacuum gauge enables pressure measurement in the vacuum system via the DCU.
Pressure measurement with the DCU
An exact pressure measurement is not possible with the DCU. This is particularly true
with linear gauges in the lower pressure range.
Use suitable measuring instrument.
