The housing can be rotated by 330° without the use of any tools. You can also install the indicating and adjustment module in four different positions (each displaced by 90°). Moisture Use the recommended cable (see chapter "Connecting to power supply") and tighten the cable gland. You can give your VEGABAR 52 additional protection against moisture penetration by leading the connection cable downward in front of the cable entry. Rain and condensation water can thus drain off. This applies mainly to mounting outdoors, in areas where moisture is expected (e.g. by cleaning processes) or on cooled or heated vessels. Fig. 2: Measures against moisture penetration 4.2 Mounting information 27507-EN-051004 Installation location VEGABAR 52 functions in any installation position1). It is mounted acc. to the same regulations like a manometer (DIN EN 839-2). 1) VEGABAR 52 - 4 … 20 mA/HART If necessary, position correction see "Setup procedure". 11 Mounting Information: We recommend using lock fittings, measuring instrument holders and siphons from the line of VEGA accessories. 4.3 Mounting procedure Welding the socket To mount VEGABAR 52, a welded socket is necessary.

Tip: We recommend VEGA overvoltage arresters ÜS-F-LB-I and ÜSB 62-36G.X. Take note of safety instructions for Ex applications In hazardous areas you should take note of the appropriate regulations, conformity and type approval certificates of the sensors and power supply units. Select power supply Power supply and current signal are transmitted via the same two-wire connection cable. The power supply range can differ depending on the instrument version. The exact range is stated in the "Technical data" in the "Supplement". Provide a reliable separation between the supply circuit and the mains circuits acc. to DIN VDE 0106 part 101. The VEGA power supply units VEGATRENN 149AEx, VEGASTAB 690, VEGADIS 371 as well as all VEGAMETs meet this requirement. Bear in mind the following factors regarding supply voltage: l l the reduction of the output voltage of the power supply unit under nominal load (with a sensor current of 20.5 mA or 22 mA in case of fault signal) the influence of additional instruments in the circuit (see load values in "Technical data"). VEGABAR 52 is connected with standard two-wire cable without screen. An outer cable diameter of 5 … 9 mm ensures the seal effect of the cable entry. If strong electromagnetic interference is expected, we recommend the use of screened cable. Cable gland ½ NPT On VEGABAR 52 with cable gland ½ NPT and plastic housing, a metal ½" threaded insert is moulded in the plastic housing. 27507-EN-051004 Selecting the connection cable VEGABAR 52 - 4 … 20 mA/HART 13 Connecting to power supply Caution: No grease should be used when screwing the NPT cable gland or steel tube into the threaded insert. Standard grease can contain additives affecting the connection between threaded insert and housing. This will influence the stability of the connection and the tightness of the housing. Cable screening and grounding If screened cable is necessary, connect the cable screen on both ends to ground potential. In the sensor, the screen must be connected directly to the internal ground terminal. The ground terminal outside on the housing must be connected to the potential equalisation (low impedance). If potential equalisation currents are expected, the connection on the evaluation side must be made via a ceramic capacitor (e.g. 1 nF, 1500 V). The low frequency potential equalisation currents are thus suppressed, but the protective effect against high frequency interference signals remains. Select connection cable for Ex applications Take note of the corresponding installation regulations for Ex applications. In particular, make sure that no potential equalisation currents flow over the cable screen. In case of grounding on both sides this can be achieved by the use of a capacitor or a separate potential equalisation. 5.2 Connection procedure Proceed as follows: Unscrew the housing cover 2 If an indicating and adjustment module is installed, remove it by turning it slightly to the left. 3 Loosen compression nut of the cable entry 4 Remove approx. 10 cm (4 in) of the cable mantle, strip approx. 1 cm (0.4 in) insulation from the ends of the individual wires 5 Insert the cable into the sensor through the cable entry 6 Lift the opening levers of the terminals with a screwdriver (see following illustration) 7 Insert the wire ends into the open terminals according to the wiring plan VEGABAR 52 - 4 … 20 mA/HART 27507-EN-051004 14 1 Connecting to power supply Fig. 3: Connection steps 6 and 7 8 Press down the opening levers of the terminals, you will hear the terminal spring closing 9 Check the hold of the wires in the terminals by lightly pulling on them 10 Connect the screen to the internal ground terminal and the external ground terminal to potential equalisation 11 Tighten the compression nut of the cable entry, the seal ring must completely encircle the cable 12 Screw the housing cover back on The electrical connection is finished. 5.3 Wiring plans, single chamber housing 27507-EN-051004 The following illustrations apply to the non-Ex as well as to the Ex ia version.

The modification of these process-relevant parameters is protected (e.g. password, ...) The safety function requires less than SIL4 45 Functional safety acc. to IEC 61508-4 (SIL) 10.2 Planning Safety function The measuring system generates on the current output a signal between 3.8 mA and 20.5 mA proportional to the process pressure or level. This analogue signal is transmitted to a connected processing unit for monitoring the following conditions: l Exceeding or falling below a set pressure value The safety function is that a signal is outputted if the set switching point is reached on the processing unit. Safe condition The safe condition depends on the mode and is stated in the following chart: Safe condition Output current in safe condition Monitoring upper pressure value Monitoring lower pressure value Exceeding of the switching point Falling below the switching point > switching point (+1 %) < switching point (+1 %) Failure current "fail low" <3.6 mA <3.6 mA Failure current "fail high" >21.5 mA >21.5 mA The current tolerance ±1 % refers to the full measuring range of 16 mA. Fault description A fail-safe failure (safe failure) exists if the measuring system changes to the defined safe condition or to the failure mode without demand of the process. If the internal diagnosis system detects an failure, the measuring system goes to failure mode. A dangerous undetected failure exists if the measuring system does neither go to the defined safe condition when required by the process nor to the failure mode. Configuration of the processing unit If the measuring system delivers output currents of "fail low" or "fail high", this can be due to a failure. 46 VEGABAR 52 - 4 … 20 mA/HART 27507-EN-051004 The processing unit must therefore interpret such currents as failure and output a suitable fault signal. Functional safety acc. to IEC 61508-4 (SIL) If this is not the case, the appropriate shares of the failure rates must be assigned to the dangerous failures. Therefore the stated values in chapter "Safety-relevant characteristics" can deteriorate. Low demand mode If the demand rate is only once a year, then the measuring system can be used as safety-relevant subsystem in "low demand mode" (IEC 61508-4, 3.5.12). If the ratio of the internal diagnostics test rate of the measuring system to the demand rate exceeds the value 100, the measuring system can be treated in the way it is executing a safety function in the mode with low demand rate (IEC 61508-2, 7.4.3.2.5). Corresponding characteristics is the value PFDavg (average Probability of dangerous Failure on Demand). It is dependent on the test interval TProof between the function tests of the protective function. Numbers see paragraph "Safety-technical characteristics". High demand mode If the "low demand mode" does not apply, the measuring system must be used as safety-relevant subsystem in "high demand" (IEC 61508-4, 3.5.12). The fault tolerance time of the complete system must be higher than the sum of the reaction times or the diagnostics test periods of all components in the safety chain. Corresponding characteristics is the value PFH (failure rate). Numbers see paragraph "Safety-technical characteristics". Assumptions The following assumptions form the basis for the implementation of FMEDA: l l l l l 27507-EN-051004 l l VEGABAR 52 - 4 … 20 mA/HART Failure rates are constant, wear of the mechanical parts is not taken into account Failure rates of external power supplies are not included Multiple errors are not taken into account The average ambient temperature during the operating time is +40°C (104°F) The environmental conditions correspond to an average industrial environment The lifetime of the components is around 8 to 12 years (IEC 61508-2, 7.4.7.4, remark 3) The processing unit can interpret "fail low" and "fail high" failures as interferences and output a suitable fault signal 47 Functional safety acc. to IEC 61508-4 (SIL) l l l General instructions and restrictions The repair time (exchange of the meas. system) after a failsafe error is eight hours (MTTR = 8 h) The scanning interval of a connected control and processing unit is max. 1 hour to react on dangerous, detectable errors The communication via the HART interface is not used for transmission of safety-relevant information The measuring system should be applied acc. to the application by taking pressure, temperature, density and chemical properties of the medium into account. The application-specific limits must be maintained and the specifications must not be exceeded. 10.3 Adjustment instructions and parameter adjustment Instrument parameters Since the plant conditions influence the safety of the measuring system, the instrument parameters must be set according to the application. VEGABAR 52 suitable for the VEGA-DTM in conjunction with an adjustment software acc. to FDT/DTM standard, e.g. PACTware™ is permitted as auxiliary means. Create a measurement loop Via the adjustment software, the parameter "Sensor acc. to SIL" must be selected in the menu item "Measurement loop". Reaction in case of failure The parameter adjustment of the interference current influences the safety-technical characteristics. For safety-relevant applications only the following inference currents are allowed: l l fail low = <3.6 mA fail high = 22 mA Note: The setting "Hold value" must not be selected. The damping of the output signal must be adapted to the process safety time. Inadmissible modes The measured value transmission by means of HART signal as well as HART multidrop mode are not permitted. Inspection possibilities The effectivity of the set parameters must be checked in a suitable way. 48 VEGABAR 52 - 4 … 20 mA/HART 27507-EN-051004 Damping of the output signal Functional safety acc. to IEC 61508-4 (SIL) l l Access locking After connecting the instrument, the output signal jumps to the set interference current (at the end of the switch on phase) In mode "Simulation", the signal current can be simulated independent of the current pressure or level To avoid unwanted or unauthorized modification, the set parameters must be protected against unintentional access: l l Activate the password protection on the adjustment program PACTware™ Activate the PIN on the adjustment module PLICSCOM The access by means of HART handheld or similar is not permitted. The protection against unintentional or unauthorized adjustment can be prevent by e.g. sealing the housing cover. Caution: After a reset of the values, all parameters must be checked or readjusted. 10.4 Set up Take note of the mounting and installation instructions of the operating instructions manual. Within the setup, we recommend checking the safety function by means of an initial filling. 10.5 Reaction during operation and in case of failure The adjustment elements must not be modified during operation. In case of modifications during operation, you have to take note of the safety functions. Occurring fault signals are described in the appropriate operating instructions manual. 27507-EN-051004 In case of detected failures or fault signals, the entire measuring system must be switched out of service and the process held in a safe condition by means of other measures. An electronics exchange is easily possible and described in the operating instructions manual. VEGABAR 52 - 4 … 20 mA/HART 49 Functional safety acc. to IEC 61508-4 (SIL) If due to the detected failure, the electronics or the complete sensor is interchanged, the manufacturer must be informed (incl. a fault description). 10.6 Recurring function test The recurring function test serves to reveal potential dangerous errors that are otherwise not discernible. The function of the measuring system must be checked at adequate intervals. The operator is responsible for choosing the type of test and the intervals in the stated time frame. The time frame depends on the PFDavg value acc. to the chart and diagram in section "Safety-related characteristics". In high demand rate, no recurring function test is arranged in IEC 61508. A proof of the functional efficiency is seen in the more frequent demand of the measuring system. In double channel architectures it is useful to proof the redundancy by recurring function tests in appropriate intervals. The test must be carried out in a way that verifies the flawless operation of the safety functions in conjunction with all system components. This is ensured by a controlled reaching of the response height during filling. If filling up to the response height is not possible, then a response of the measuring system must be triggered by a suitable simulation of the level or the physical effect. The methods and procedures used during the tests must be stated and their suitability must be specified. The tests must be documented. If the function test proves negative, the entire measuring system must be switched out of service and the process held in a safe condition by means of other measures. In the double channel architecture 1oo2D this applies separately to both channels. 10.7 Safety-related characteristics Failure rates VEGABAR 52 - 4 … 20 mA/HART 27507-EN-051004 50 The failure rates of the electronics, the mechanical parts of the pressure transmitter as well as the process fitting were determined by an FMEDA acc. to IEC 61508. Basis for the calculations are component failure rates acc. to SN 29500. All Functional safety acc. to IEC 61508-4 (SIL) values relate to an average ambient temperature during operation of +40°C (104°F). The calculations are further based on the instructions stated in chapter "Planning".
