The 8400 controller has been designed to measure the temperature of a
liquid or a gas.
There will be no manufacturer warranty for damages caused by unexpect-
ed handling or wrong usage of the device. The warranty on the device
becomes invalid if any modification or change is made on the device.

- When the device is powered and the cover is open, protection against
electric shocks is not ensured.
- To clean the device, only use chemically compatible products.
- Always protect the device from electromagnetic perturbations, ultravio-
let radiations and, when installed outside, from the effects of climatic
conditions.

The temperature controller 8400 is an electronic module which has to
be inserted into an holder previously mounted on a wall. It may switch a
solenoid valve, activate an alarm or establish a control loop.
It must be associated to a remote 3-wire Pt100 temperature sensor.
The switching point can be adjusted by means of the three keys located
under the display.
The electrical connection is carried out via a steerable 5-pin M12 male
connector and a 4-pin M12 female connector.
The controller 8400 measures the resistance of the remote Pt100 sen-
sor.

Always check the chemical compatibility of the materials the controller is
made of with the products it may be in contact with, for instance: alco-
hols, strong or concentrated acids, aldehydes, bases, esters, aliphatics,
aromatics, ketones, aromatics or halogenated hydrocarbons, oxidizing
agents and chlorinated products. For more information, please contact
your Bürkert sales office.
1. Select the location of the holder on a wall, then drill 4 holes by
respecting the hole-to-hole distances indicated on the opposite
schematic and mount the holder using 4 screws.
