Page 15: Connecting To Power Supply
861 must be connected to the potential equalisation (low impedance). If potential equalisation currents are expected, the screen connection on the side of VEGAMET 861 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. -
Page 16: Sensor Input Mode Active/Passive
The VEGAMET 861 can also be looped into the existing circuit like a normal ammeter. Note: With a VEGAMET 861 in Ex version, the passive input is not available. Digital input mode active/passive Through the selection of the terminals, you can choose between ac- tive and passive operation of the digital input. -

Only carry out the adjustment on one instrument, either on VEGAMET 861 or on the sensor. The adjustment in VEGAMET 861 is always car- ried out in mA (analogue transmission). Digital HART transmission For transmission via HART, VEGAMET 861 must be informed which sensor value should be used for further processing.

- Page 42 Normally (in fair weather), a pump with low capacity (dry weather pump) is sufficient to maintain the level in the retention basin at a safe level (Hi-Level). If heavy rainfall causes an increased inflow, the fair weather pump can no longer maintain the level. In such cases, a larger pump is switched on when the HiHi level is exceeded and the dry weather pump is switched off. The large pump then remains in operation until the switch-off point is reached. If the level rises again, the dry weather pump switches back on first. VEGAMET 861 • 4 … 20 mA/HART...

Page 47: Flow Measurement Flume/Weir
This constriction creates a certain backwater depending on the flow rate. The flow rate can now be derived from the level of this backwater. The current flow rate is shown on the display in the selected unit of measurement (e.g. m /h). In addition, the flow rate is made available via the current output and can thus be further processed by down- stream devices. It is also possible to totalize the flow rate by means of a totalizer, the result is shown on the display (e.g. in m ). In addition, the flow rate can VEGAMET 861 • 4 … 20 mA/HART... - Page 48 • Triangular overfall thin-walled (ISO 1438) • Rectangular flume thin-walled (ISO 1438) • Rectangular weir broad crown (ISO 3846) Flow formula If the flow formula of your flume is known, you should select this op- tion, as the accuracy of the flow measurement is highest here. • Flow formula: Q = k x h Manufacturer definition If you use a Parshall flume from the manufacturer ISCO, this option must be selected.
