1 SAFETY RECOMMENDATIONS
Always respect the safety instructions marked by the symbol
opposite as well as those included in the manual.
1.1 Utilisation
The 8400 or 8400 Extended controller has only been designed to
measure the temperature of a liquid or a gas.
There will be no manufacturer warranty for damages caused by
unexpected handling or wrong usage of the device. The warranty on the
device becomes invalid if any modification or change is made on the
device.
The device should only be installed and repaired by specialist
staff.
The user is not allowed to work on the cables inside the housing.
If any difficulties may occur with the product during installation,
please contact your nearest Bürkert sales office for assistance.

ENGLISH ENGLISH
1.2 Precautions at installation and commissioning
- When the device is powered and the cover is open, protection
against electric shocks is not ensured.
- Always ensure the materials in contact with the medium to
measure are chemically compatible.
- To clean the device, only use chemically compatible products.
When dismounting the controller from the pipe, take all the
necessary precautions linked to the process.
Always ensure the tightness between the controller and the
pipe.
1.3 Conformity to standards
EMC: EN 50 081-1, 50 082-2
Security: EN 61 010-1
Vibration: EN 60068-2-6
Shock: EN 60068-2-27

ENGLISH ENGLISH
Temperature Controller 8400
2.1 Design
The temperature controller 8400 or 8400 Extended is made up of an
electronic module and a measuring element. It may switch a solenoid
valve, activate an alarm or establish a control loop.
The switching point can be adjusted by means of the three keys located
under the display. The adjustment can optionally be carried out by
means of a 4-20 mA loop via an external controller.
The controller housing can be turned by 180°.
The electrical connection is carried out via a DIN 43650 connector
(type 2508) and/or an M12 multipin connector.
2.2 Measuring principle
The controller uses a Pt100 measuring resistance.
The controller 8400 is fitted with a 46-mm long sensor.
The controller 8400 Extended is available with a 100-mm or a 200-mm
long sensor.

4.3 Electrical connection
Always ensure the power supply is switched off before working on the
device. All the connectors must be plugged out. Use:
- a shielded cable with an operating temperature > +80° C (+176° F).
- a high quality voltage supply (filtered and stable).
Install the following security devices:
- for the power supply: a 1-A fuse
- for the relay: a 3-A fuse and a circuit breaker (depending on
the application).

5 PROGRAMMING
5.1 General recommendations
Keep in mind that the process may be influenced by all the parameter
settings you make. Fill-in the table on page 22 with your settings of the
controller.
5.2 Functionalities
The device has three operating modes :
Normal Mode
Display of the measured temperature and the switching thresholds
programmed. From the Normal mode, you can access the Calibration
and Simulation modes.
Calibration Mode
Access to the programming of all the parameters (unit, output, filter, bargraph,
temperature adjustment, extension board parameters). From the Calibration
Mode, you can go back to the Normal Mode.
Simulation Mode
Entering a theoretical temperature value to test the configuration
programmed in the Calibration Mode. You may also calibrate the
optional extension board. From the Simulation Mode, you can go back to
the Normal Mode.

5.6 Possible switching modes of the 8400
Hysteresis Mode
The change of state occurs when a threshold is detected
(increasing temperature: high threshold (OHI) to be detected,
decreasing temperature: low threshold (OLO) to be detected).
Window Mode
The change of state occurs when any
threshold is detected.
The delay (DEL) is set for the both switching
thresholds. The switching only occurs when
either threshold value (OHI - OLO) is exceeded
for a duration higher than the DEL delay.
