5. Transport, packaging and storage
5.1 Transport
Check the dierential pressure transmitter for any damage that may
have been caused during transportation. Obvious damage must be reported immediately.
5.2 Packaging
Do not remove packaging until just before mounting. Keep the packaging as it will provide optimum protection during trans­port (e.g. change in installation site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
Storage temperature: -20 ... +70 °C Protect the instruments from moisture and dust.
6. Commissioning, operation
Installation and mechanical connection
Protect measuring instruments from contamination, high temperature changes and vibrations
In order to avoid any additional heating, the instruments must not be exposed to direct solar irradiation while in operation.
The dierential pressure transmitter must be screw-tted on a
suitable vertical surface. The instrument has to be mounted horizon­tally using the enclosed mounting screws.

6. Commissioning, operation
Electrical connection
The instruments are designed to operate with safety extra-low voltage
(SELV). When wiring up the instruments, the technical specications for
those instruments should be followed. As a rule, the transmitter should
GB
be operated in the middle of the measuring range, since deviations can occur at the range limits. The ambient temperature of the transmitter electronics should be kept constant.
The dierential pressure transmitters must be operated at a constant
operating voltage (±0.2 V). Current/voltage spikes from switching the
power supply on or o must be prevented by the customer.

Output signal 0 ... 10 V
Output signal 4 ... 20 mA
Supply voltage AC 24 V / DC 24 V
Commissioning
A prerequisite for the commissioning is a proper installation of all electrical supply, control and measuring lines and of the pressure connection lines. Before commissioning, the leak tightness of the pressure connection lines must be checked.
7. Zero point adjustment
7.1 Standard
Attention! The power supply must be connected one hour before calibrating the zero point. Remove both hoses from the pressure
connections ⊕ and ⊖.
Press the zero key until the red LED switches on.
Wait until the LED switches o again and install the hoses to the
pressure connections again.
In normal operation, we recommend that a zero point calibration is carried out every 12 months.
7.2 Automatic zero adjustment (option)
The automatic zero adjustment makes the instrument maintenance­free. The element adjusts the zero point from time to time and thus prevents a zero point drift of the piezo-resistive sensor element.
During the zero adjustment the display and output value remains at the last measured value. The automatic zero adjustment takes 4 seconds and is repeated every 10 minutes.

9. Maintenance and cleaning
The dierential pressure transmitter is maintenance-free and oers long
service life provided it is handled and operated properly.
Clean the instruments with a moist cloth (soap water).
Repairs must only be carried out by the manufacturer or appropriately
qualied skilled personnel.
10. Disposal
Incorrect disposal can put the environment at risk.
Dispose of instrument components and packaging materials in an environmentally compatible way and in accordance with the country-
specic waste disposal regulations.
