  • Page 15: Connecting To Power Supply

    862 must be connected to the potential equalisation (low impedance). If potential equalisation currents are expected, the screen connection on the side of VEGAMET 862 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.

    The VEGAMET 862 can also be looped into the existing circuit like a normal ammeter. Note: With a VEGAMET 862 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.

  • 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 862 • 4 … 20 mA/HART...
