- The 8311 controller has only been designed to measure the relative
pressure of a liquid or a gas
- The following units are available to display the measured pressure: bar,
kPa, psi, mPa, Torr, mmHg, atm, MWS, mbar
- The measuring element must be solidly screwed onto its support
There will be no manufacturer warranty for damages caused by unexpec-
ted handling or wrong usage of the device The warranty on the device
becomes invalid if any modification or change is made on the device
ENGLISH
ENGLISH
- When the device is powered and the cover is open, protection against
electric shocks is not effective
- Always ensure the materials in contact with the medium to measure
are chemically compatible
- To clean the device, only use chemically compatible products
- Do not insert any object (screwdriver for instance) inside the sensor
body If the body is dirty, use compressed air to clean it
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

The pressure controller 8311 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 controller housing can be turned by 180°
The controller 8311 can be inserted in a fitting before being mounted on
any type of pipe
The electrical connection is carried out via an EN175301-803 connector
and/or a steerable M12 multipin connector
The controller 8311 uses a piezo-resistive ceramic cell

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
The pressure controller 8311 can be inserted in a fitting before being
mounted on any type of pipe
During mounting, follow the instructions given with the fitting
Always replace the cover
in its initial position
Do not tighten the controller
using the housing;
use an appropriate tool
For a G1/2”-version,
ensure the gasket is in
place

Always ensure the power supply is switched off before working on the
device All the cable plugs must be plugged out Use:
- a shielded cable with an operating temperature > +80 °C
- a high quality voltage supply (filtered and regulated)

- To open the plug, unfasten screw [1]
- Remove part [3] from part [2]
- Unscrew cable gland [5]
- Insert cable into part [2] via cable gland
- Wire part [3] (see 433)
- Replace part [3] into part [2], by 90°-steps
- Tighten cable gland [5] Place gasket [4] between the cable plug and
the fixed connector of the controller and plug the 2508 onto the fixed
connector
- Tighten screw [1] to ensure tightness and correct electrical contact
- Loosen threaded ring [1]
- Remove part [2] from the connector

When the voltage at the relay terminals is higher than 24 V and the
cable plugs are not correctly plugged-in and tightened, there is a risk to
electrocute yourself
Always check all the cable plugs before powering the device to ensure
the good operating of the device

Keep in mind that the process may be influenced by all the parameter
settings you make Fill-in the table on page 24 with your settings of the
controller
The device has three operating modes:
Display of the measured pressure and the switching thresholds pro-
grammed From the Normal mode, you can access the Calibration and
Simulation modes
Access to the programming of all the parameters (unit, zero adjustment,
K-factor, calibration through the „Teach-in“ feature, output, filter , bar-
graph) From the Calibration mode, you can go back to the Normal Mode
Entering a theoretical pressure value to test the configuration program-
med in the Calibration mode From the Simulation Mode, you can go
back to the Normal mode

At the first powering up, the configuration of the controller 8311 is as follows:
Pressure unit: bar
Output: hysteresis
OLO: 0,2 bar
OHI: 1 bar
DEL: 0 s
Filtre: 2
BGLO: 0 bar
BGHI: max value of the measuring range
Extension board: no
