3.4. Making The Connections
– The units DCU 100 - DCU 600 have been designated protection class 1 and must always be
connected with the earthed conductor (PE) via the mains cable.
Please note: If using the TC 600 electronic drive unit, please disconnect the remote plug from
the RS 485 interface connection.
➡Mains connection must be made in accordance with the local regulations.
➡Make the connection X2 - Electronic Drive Unit in accordance with the connecting diagram,
section 3.3.
➡Make the connection pressure gauge to X3 as required.
–> PPlleeaasseennoottee::if connecting a pressure gauge PCR 260, “TPR” is shown at the display.
➡Make the connection RS 485/DCU-RS 485/Electronic Drive Unit via the delivered 8 pole cable.

respectively.
➡Depress key and simultaneously.
–> The arrow (--->) disappears.
–> The parameter is set.

4.2. General
All function relevant aspects of the pump electronics are illustrated in the form of parameters.
Each parameter has a number and a designation (for example, “720: Vent frequ”).
The value of the parameter is always readable, in some cases also modifiable via the keyboard.
4.3. Switching On The Control Unit
➡Make the connection to the Serial Interface RS 485.

➡Switch on the DCU by the switch S1 on the rear side.
➡In the event of an error message: depress: .
Self-Testing
After switching on, the DCU performs a self-test and also a test on the connected turbo electro-
nics. Run time of the self-test: approx. 20s. During the test a bar appears in the display in line 4
and this shows the progress of this procedure.
•DDiissppllaayytteesstt::All signs in the LC display are shown for a short time in black.

4.5. LC-Display
The functions are displayed via a four line LC display. A special function is assigned to each line:
–LLiinnee11::Number and name of the selected parameter (for example 721: >>Vent time<<).
–LLiinnee22: Relating value. If an arrow (--->) is displayed, the displayed value can be altered.
–LLiinnee33::Two functions
FFuunnccttiioonn11: Messages relating to operations and operating are displayed. (see table
“Operating Messages” in the operating instruction “Pumping Operations with DCU” and
“Error Codes”, section 5).
FFuunnccttiioonn22: An optional second parameter in the form of >>Parameter number<< : >>value<<
is displayed. The function of this line enables setting via parameter [[PP::779955]]>>Servicelin<< at
line 1 . With >>Servicelin<< all parameters can be displayed. Error messages are displayed
independent of the selected function.
–LLiinnee44: Arrows which points to the underlying symbol. This restores the unit status.
Please note:
Prolonged depressing of the key or enables rapid scrolling and/or alterations to the data.
The data mode (arrow ”--->” is displayed) is automatically relinquished, without taking over the
values to be altered, under the following conditions:
– No settings or key depressing for longer than 10 seconds.

6. What To Do In Case of Breakdowns ?
7. Maintenance And Service
Check the fuses
In case of an error:
➡Loosen F1/F2 with a screwdriver and check fuses. Replace if defective.Only use fuses with
high switching capability.
The safety values are stated on the rear panel of the DCU.
Caution! Double pole / neutral fusing!
CAUTION
The unit requires no maintenance. A damp cloth can be used to wipe away any dirt which has
collected on the front panel. Ensure that the unit is first disconnected from the mains power
supply.
Do Make Use Of Our Service Facilities
In the event that repairs are necessary a number of options are available to you to ensure any
system down time is kept to a minimum:
– Have the unit repaired on the spot by PFEIFFER Service Engineers;
– Return the unit to the manufacturer for repairs;
– Replace with a new value unit.
Local PFEIFFER representatives can provide full details.
When carrying out their own repairs customers must bear in mind that dangerous
voltage levels are present.
Please note:
Units returned to us for repair or maintenance are covered by our general conditions of sale and
supply.
