  • Page 32 OFF. The switching points are set as follows: • Relay 1: Switch-off point 90 %, switch-on point 85 % • Relay 2: Switch-off point 5 %, switch-on point 10 % Information: The switch-on and switch-off point of the relays must not be set to the same switching point because this would cause a continuous switch- ing on and off when this threshold is reached. To avoid this effect also with fluctuating medium surfaces, it is a good idea to set a difference (hysteresis) of 5 % between the switching points. VEGAMET 341 • 4 … 20 mA...

  • Page 36 Which pump is switched on depends on the selected pump mode. If all pumps are already switched on, the pump remains switched on. VEGAMET 341 • 4 … 20 mA...
  • Page 37 90 % limit, pump 3 is also switched on. For relay 1 … 3, the mode of operation " Pump control 4" is adjusted with the option " Sequenced operation". The relay switching points are configured as follows: VEGAMET 341 • 4 … 20 mA...
  • Page 38 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. There is also the possibility of using multiple large pumps in alternat- ing mode. The algorithm for the switching function is then determined by the pump control mode. VEGAMET 341 • 4 … 20 mA...
  • Page 39 Since in this case all pumps operate alternately in the same area, their switch-on and switch-off points must be the same. In addition, the mode " Alternating pump operation" must be active. VEGAMET 341 • 4 … 20 mA...
