Mounting 2 Mounting 2.1 Mounting instructions The pressure transmitter 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. 2.2 Compensation of the atmospheric pressure On instruments for gauge pressure measurement, the atmospheric pressure is compensated via a breather facility integrated in the housing.
Electrical connection 3 Electrical connection 3.1 Connection instructions The electronics in the pressure transmitter requires a supply voltage of 12 … 32 V DC. It is designed in two-wire technology, i.e. the supply voltage and the digital output signal are led via the same two-wire cable to the terminals. This external energy is provided via a separate power supply unit, e.g.: - power supply unit VEGASTAB 690 - processing unit with integrated DC voltage source (e.g.
Electrical connection Sensors used in Ex areas must be connected only to intrinsically safe circuits. The permissible electrical values are stated in the conformity certificate or the type approval certificate. Electronics version B Digital output signal for connection to a digital VEGA signal conditioning instrument (VBUS) Internal connection Zum Anschluss an For connection to Intrinsically safe circuits with more than one active instrument (instrument delivering electrical energy) are not allowed.

Electrical connection 3.4 Connection examples Note: An ammeter for local control of the output current can be connected to terminals 1 and 3. This measurement can be carried out during operation without interrupting the supply cable. The following connection examples are valid for direct connection to the terminals of the pressure transmitter. When using the external connection housing, the connection is made to the respective terminals of the housing.
Setup 4 Setup 4.1 Adjustment structure The hydrostatic pressure transmitters come with or without adjustment capability. After connection to the supply voltage, the electronics carries out a self-test (approx. 2 sec.) and the current in this signal circuit (sensors with analogue output signal) takes on a value of > 21.6 mA. Sensors with adjustment (electronics version A and C) Sensors with electronics version A deliver a pressure-proportional current as measured value and are not adjustable.
Setup Adjustment with PC and adjustment program VVO (electronics version B, I, K and L) With the adjustment program VVO (VEGA Visual Operating) on the PC you can conveniently adjust the pressure transmitters with electronics version B, I, K and L. The PC communicates through the interface converter VEGACONNECT 2 or the standard RS 232 interface cable with the sensor. A digital adjustment signal is superimposed on the signal and supply cable.
Setup S Z ti Op 1 2 3 4 5 + - 4...20mA 12V...36V DC Bedieneinsatz operating unit Note: - A modification of zero does not influence the span, i.e. the measuring range final value is simply shifted. - It is also possible to adjust currents for partial fillings or partial pressures, e.g. 8 mA for 25 % and 16 mA for 75 %.The pressure transmitter then automatically calculates the values for 0 % or 100 % (only possible with a level difference >3.3 %).
Setup 4.4 Setup with HART ® handheld Sensors with electronics versions I, K and L can be set up with the HART ® handheld. A special DD (Data Device Description) is not necessary. Just connect the HART® handheld to the sensor signal cable after you have connected the sensor to supply voltage. Note: If the resistance of the voltage supply is less than 250 Ω, a resistor must be looped into the signal/connection cable during adjustment.
Setup The most important adjustment steps On the following four pages you see a menu schematic of the HART® handheld in conjunction with pressure transmitters D80 … D87. The most important adjustment steps are marked in the menu schematic with the letters A … D. If you are not familiar with HART® handheld, please note: After a moment, you are asked to switch the system from manual to automatic operation.

Setup 5.5 Adjustment with PC directly on the sensor (electronics versions I, K and L) For connection of the PC to the sensor, the interface converter VEGACONNECT 2 is required. Connection of the PC to the sensor Insert VEGACONNECT into the standard connection of the PC and insert the two-wire cable of VEGACONNECT into the CONNECT socket in the sensor. Connection of the PC to the signal cable Connect the two-wire cable of VEGACONNECT 2 to the signal cable leading to the sensor.
Setup If you have already connected the PC with the adjustment software VVO to your measuring system, • first switch on the power supply of the connected sensor • switch on the PC and start the adjustment software VVO. • Choose with the arrow keys or the mouse the item "Planning" on the entrance screen and click to "OK ". The adjustment program (VVO), called in the following VVO, gets into contact with the connected sensor… …and indicates after a few seconds if and with which sensor a connection exists.
Setup Note: When connecting the adjustment software (VVO) to a sensor from which data has already been saved, you are asked if the saved data should be transferred to the sensor or if you want to transfer the sensor data to the database of VVO (the available data of the current sensor will be overwritten). If you don’t get communication with the sensor, check the following: - Is the sensor being supplied with sufficient voltage (min.
Setup • Choose in the menu window "Instrument data parameter adjustment" the menu item "Adjustment". • In the menu window "Adjustment " you click to "Min/Max-adjustment " (zero/span). Parameter adjustment/Adjustment In the menu " Instrument data/Parameter adjustment" you carry out all important sensor adjustments. • Choose the menu "Instrument data/Parameter adjustment". You can carry out the min./max. adjustment with or without medium. Generally you will carry out the adjustment without medium.
Setup • Click to "Offset correction". • When the sensor is unpressurised and in installation position, confirm the safety enquiry with "OK". In the example, this is an absolute pressure transmitter with a measuring range of 0 … 1000 mbar, with which low pressures (partial vacuum) are measured. The min. value was set to 50 mbar and the max. value (span) to 1000 mbar (i.e. the final value of the measuring range).
Setup Again choose the menu "Offset correction" and you see the corrected zero value. Note: The menu item "Real value correction " enables the correction of the actual pressure by means of a reference value. This corrects the measuring characteristics in a way similar to the offset correction. You can choose four linearisation curves: linear, horiz. cylindrical tank, spherical tank and user programmable curve.
Setup In the field "Transfer measured value" the current pressure as a percentage of the adjusted span is displayed. The measuring span has already been adjusted with the min./max adjustment. In our example this is in the range between 50 … 1000 mbar.
Setup Meas. data information • Click to " Meas. data info". Saved sensors can be transferred later on to other sensors. For example, if you have a system with several of the same storage vessels and identical sensors, it is sufficient to configure one sensor and then transfer the settings to the other sensors. All available sensor information is displayed. With the button "reset " you can delete the pressure and temperature history saved in the sensor.
Diagnostics 6 Diagnostics Maintenance The pressure transmitter D80 is maintenance free. Checking electrical connections Pressure transmitter terminals 1 2 3 Voltage V Current mA External energy source Error rectification - Through continuous self-monitoring, series 80 pressure transmitters offer maximum reliability.
Instrument modification 7 Instrument modification 7.1 Retrofitting the adjustment insert Such a retrofitting can be necessary, e.g. when a pressure transmitter with factory setting must be adapted to changed measurement conditions. Note the following retrofit procedure: • remove the preset terminal insert • mount new adjustment insert • set up pressure transmitter acc. to chapter "5 Setup" Remove the present terminal insert 1 2 3 4 5 6 Separate pressure transmitter from power supply.
