Product description 1 Product description 1.1 Function and configuration 1.2 Self-monitoring VEGABAR 44 process pressure transmitters are efficient instruments for process pressure measurement. As pressure sensor element, the dry ceramic-capacitive measuring cell CERTEC® is used. The process pressure causes a capacitance change within the measuring cell via the diaphragm.

Mounting, Electrical connection 2 Mounting 3 Electrical connection 2.1 Mounting instructions 3.1 Connection instructions VEGABAR can be mounted in any position. Cable entries must point downwards to avoid moisture ingress. For this purpose, the housing can be rotated by 330° in relation to the mounting part. The electronics in VEGABAR 44 requires a supply voltage of 12 … 36 V DC. It is provided in two-wire technology, i.e.
Electrical connection Note the following instructions for electrical connection: - Connection must be made according to the specific installation standards (e.g. in Germany acc. to the VDE regulations). - Terminal voltage must not exceed 36 V, to avoid damage to the electronics. - Electrical connection must have a preventative measure against inadvertent polarity reversal. - The wiring between VEGABAR and the power supply can be carried out using standard two-wire cable.
Electrical connection 3.3 Connection examples Supply via power supply unit Processing is carried out using an indicating instrument. Ammeter for local control analogue / digital indicating instrument + – 1 2 – VEGABAR terminals 3 Power supply unit – ~ + Supply via a PLC with active input circuit Processing is carried out via a PLC with active input circuit.
Setup 4 Setup Electrical connection and setup can be simplified by temporarily mounting the cover or the indicating module on VEGABAR laterally or downwardly displaced. Indicating module VEGABAR 4.
Setup 2 Adjustment of span (e.g. process pressure or level at maximum) • Set rotary switch to span. • By pushing the "+“ and "–“ keys simultaneously, the current jumps directly to 20 mA or set it to 20 mA by pushing the "+“ and "– “ keys. Adjustment range of span: 3.3 % … 120 % of the nominal measuring range (corresponds to turn down 1 : 30) Note: - A modification of zero does not influence the span, i.e. the final value of the measuring range will simply be shifted.

Note: - A modification of zero does not influence the adjusted span, i.e. final value of the measuring range will simply be shifted. - By pushing the "+“ or "–“ keys individually, the current output remains at the last value, it takes on the adjusted value only after storing with the "OK“ key.

Diagnostics 5 Diagnostics 5.1 Maintenance VEGABAR process pressure transmitters are maintenance-free. On instruments with menu-driven adjustment with additional functions, the possible reasons are displayed under the menu item "Diagnostics no.“. Diagnostics no. 5.2 Failure rectification Fault signals VEGABAR provides maximum reliability with its self-test and continuous self-monitoring. VEGABAR diagnostics distinguishes between atypical process conditions and faults in the VEGABAR.
Diagnostics Checking pressure compensation Open the housing of VEGABAR. The measured value must not change. However, if the displayed value changes, compensation of the atmospheric pressure is not ensured, which will lead to distortion of the measured value. Check the breather on the VEGABAR housing.
Instrument modification 6 Instrument modification 6.
Instrument modification 6.2 Exchange of electronics You first have to remove the adjustment module as described in chapter "6.1 Exchange of adjustment modules“, in order to exchange the complete electronics module of VEGABAR. Ground screw Note: No new adjustment is necessary after exchanging the electronics module. When switching on (connection of supply voltage) for the first time after exchange of the electronic unit, it takes approx. 20 s until the actual measured value is displayed.
Instrument modification 6.3 Exchange of the hygienic form seal On the VEGABAR 44 process pressure transmitter with hygienic fitting LA or LB, the ceramic measuring cell is sealed by a gapless, radial form seal. This form seal (material EPDM-FDA 1) approved) can be exchanged by the user without readjustment being necessary. The criteria and time periods for such an exchange are determined by process conditions and hygienic requirements.
