The filling noise, which results from the pneumatic filling of the silo, f,u accounted for bya dynamic signal evaluation. It is connected to fmh Transducer Block TB 1 and contains the following parameters: The cables of different groups must be separated. Depending on the height at which it is mounted, the limit switch acts as a minimum limitor a maximum limit switch. For two-channel units the types of both sensors must beentered.

If no correction using the selected counting units is possible, then the warningmessage E is displayed. The distanceD is determined from the velocity of sound c and the run time t by the formula: Main value 1 and flow counterIn order to transmit main value 1 and the flow counter, select the modules in the fol-lowing order: With a working contact a normally open thecurrent path u-a is open when the relay isde-energized and closed when it is energised.

Power supply unit 24 V DC for sensor heatingwith integrated overvoltage protection for power supply. For all level entries the numerical values must always refer to the same unit oflength, as defined in V8H3.

The difference between auseful signal echo and a noise signal. Mount the protective housing in a shaded area.

The parametersof linearization are entered in matrix line V2 for channel 1 and line V5 for channel 2. The LED of the relay for fault indication lights during normal operation.

The separate transmitter electronics is connected by a standard multicore cable mfu scope of delivery. Having activated linearization, the points are sorted according to rising level andsubjected to a plausibility check.

The end of the measuring range is determined by the attenuation of the ultrasonic pulseby the air fmi well as by the strength of the reflection from the product surface.

If a different linearisation is chosen, the manually entered characteristic remains storedin the Prosonic FMU, without being used. Linearization zeroThe level entries for linearization and the level entry for the empty adjustmentmust both refer to the same zero point.

A reset does not automatically set the display to a f,u Protective grounding earth terminalA terminal which must be connected to earth ground prior to making any other connection tothe equipment.

Open the protective cover. The exact level is, for example, measured with a dip stick andthen entered in Vmu. The manual must have been read fju understood,and the instructions followed. A characteristic curve can be manuallycarried out with maximum 32 point for low damming heights.

The entry is made in field V3H4 for channel 1 orV6H4 for channel 2. Matrix positions for channel 2 inbrackets. They can be connected as follows: Basic setting Basic adjustment and Setting the totalisersNote! Application parameter 4Bulk solids, rapidchangesApplication parameter 4, see Fig.

Setting of the device address1. With the last pair of values the largest volume to be fju and thecorresponding level should be entered. If you afterwards alter the flow units, the analogue output see chapter 6 and the relayswith the function Limit value must be set afresh see chapter 7.


Units connected to the currentoutput are entirely unaffected by this digital signal. The fault function can be rmu to any of the relays see Section 9. The LED of the relay lights up when the relay energises.

If strong sunlight is expected, then itis advisable to fit an all-weather protective cover obtainable 680 accessory. Thehigher this ratio is the better the echo can beevaluated 10 dB or larger is acceptable. After determining the length units, this can only be altered when all otherparameters are also changed. These characteristics are memorised for the weirs or flumes fm the right one has tobe activated by specifying a characteristic number.

Valid device addresses are in the range from 1 to V8H9 Internal counter low The last four digits of the eight digit softwarecounter are displayed.

All available characteristics canbe found in Appendix A. Separate limit switchinputAll Prosonic transmitters have an additional limit switch input. The Prosonic FMU compensates forvariations in temperature as the integrated sensor for temperature also providestemperature information.

The signal current reduces with increased values. The board with the transmitterelectronics is mounted separatelyin the control cabinet. Basic settings Basic adjustment and Linearization, only necessary for special applications. If the address is not set correctly, the device will not be recognised by the process control system.
