1. Introduction
Anton Paar GmbH thanks you for buying the TCU 1000 temperature
control unit, a powerful instrument of compact design and high reliability.
Modular design and simple configuration allow fast and optimum
adaptation to the specific demands of each application.
The TCU 1000 is optimized for work with the HTK 1200 by Anton Paar
GmbH.
The TCU 1000 controller and power unit are installed in a 19" rack which
can also be used as table housing.
The temperature control unit can be operated either by using
the front panel buttons or through the RS 232C serial port.
To ensure reliable operation of the TCU 1000, Anton Paar GmbH
recommends the accessory part as follows:
70067 FLOW CONTROLLER

2. Safety instructions
• This handbook does not purport to address all of the safety issues
associated with the use of the TCU 1000 and samples. It is the re-
sponsibility of the user to establish health and safety practices and
determine the applicability of regulatory limitations prior to use.
• Before using the TCU 1000 read this handbook completely.
• Installation procedures may only be carried out by authorized per-
sonnel who are familiar with the installation instructions.
•Anton Paar GmbH only warrants the proper functioning of the TCU
1000 if no unauthorized adjustments have been made in mechanical
parts, electronic parts and software and the following points are
adhered to.
• Follow all hints, warnings and instructions in the handbook to ensure
the correct and safe functioning of the TCU 1000.
• Do not use the TCU 1000 for any purpose other than described in the
handbook.
• Do not use any accessories other than those supplied or approved
by Anton Paar GmbH.
• The installation procedure should only be carried out by authorized
personnel who are familiar with the installation instructions.
• Do not operate the TCU 1000 if a malfunction is suspected,
or damages, injuries or loss of life cannot be excluded under all
circumstances.
• The TCU 1000 is not an explosion-proof instrument, and therefore
must not be operated in areas where there is a risk of explosion.
• Service and/or maintenance procedures which involve removing
outside covers and working with the power on may only be
performed by authorized service personnel.
• Ensure that all operators are fully trained in the correct use of this
instrument and its safe operation.
• Due to the nature of the measurement, the measuring results not only
depend on the correct use and functioning of the TCU 1000, but may
also be influenced by other factors. We therefore advise that the
analysis result are plausibility tested the before consequential actions
are taken.

8B39IB14-C
• Repair and service procedures may only be carried out by authorized
personnel or by Anton Paar GmbH.
•CAUTION: During operation and even after turning off the TCU 1000
(while the heating phase is on), temperatures at the HTK 1200 sample
holder range from room temperature to +1200°C. Make sure that the
sample holder is at room temperature before handling it.
• Follow the precautions below for the handling and measurement of
inflammable samples and cleaning materials:
- Donotstoreinflammablematerial neartheTCU1000.
- Donotleave samplecontainers uncovered.
- Clean all spills immediately.
- Ensure that the TCU 1000 is located in a sufficiently ventilated area, free from
inflammable gases and vapours.
- Connect the TCU 1000 to the mains via a safety switch located a safe
distance from the TCU 1000. In an emergency, turn off the power using this
switch. Do not use the TCU 1000 power switch.
- Keep a fire extinguisher at hand.
- Do not leave the TCU 1000 unattended while in use.
Do not touch areas marked with this sign while the power is turned on.

6. Installation of the TCU 1000
6.1 Installation
The TCU 1000 control unit can be either installed in a 19" rack or used
as table housing.
If the instrument will be installed into a rack, the supplied guide bars
have to be used.
The instrument should be protected from humidity.
Hint:
• Allow sufficient time for the instrument to reach room temperature
before starting the operation (danger of condensation).
6.1.1 Use as table housing
Make sure, that there is enough space for the connecting cables at the
rear of the instrument.

14 B39IB14-C
6.1.2 Installing into a 19" rack
For using the TCU 1000 into a 19" rack, the supplied guide bars have to
be attached.
To mount the guide bars, proceed as follows:
1
2
1. Loosen the screws (2) on both sides
of the instrument´s bottom.
2.Remove the covers (1)
3.Mount the guide bars (3) on both sides
of the instrument by using the four
screws (4) which are supplied with the
mounting set.
3
4
4
4.Make sure, that the guide rails are assembled in the 19" rack
to avoid damage when mounting the instrument into the
rack.

15B39IB14-C
6.2 Mains connection
The mains connector (1) is located at the rear
of the instrument.
The TCU 1000 is operated on 230 VAC ±10%.
Maximum power consumption is 1750 VA.
Hint:
• The protective conductor of the instrument
has to be connected to ground! 1
6.3 Connecting the HTK 1200 camera
Connect the cables from the heater output and temperature sensor, which
are at the rear of the instrument to the appropriate terminals and
connectors of the HTK 1200.
For further instructions see HTK 1200 Handbook, chapter 7.3
Hint:
• Connect the "HEATER OUTPUT" cables before connecting the
"TEMPERATURE SENSOR" cable.
Warning:
• Turn the power off and unplug the instrument before replacing the
mains fuses.

16 B39IB14-C
6.4 Connecting the flow controller
The flow controller has to be connected to
the "WATERFLOW CONTROL" connector (1)
at the rear panel.
A suitable flow controller (Cat. No. 70067) is
available from Anton Paar Gmbh 1
Hint:
• A well-functioning cooling water cycle through the HTK 1200 chamber
combined with the flow controller is a precondition for reliable TCU
operation.
Therefore, the flow controller has to be connected in any case.
To check the display for the cooling water cycle function and the
operation
of the flow controller, periodically disconnect the cooling water supply.
6.5 Connecting the sample spinner
If the HTK 1200 is equipped with the sample spinner,
the appropriate cable has to be connected to the
"SAMPLE SPINNER" connector (2) at the rear panel.

The RS 232 C serial port at the rear panel allows to interface a computer
for controlling the EUROTHERM controller .
According to EN60950 standards, the RS 232 C serial interface represents
a SELV circuit which therefore is allowed to be connected exclusively to
SELV or SELV-E circuits.
