Monitoring excess flow
With this function the position of the display window within the
detection range can be defined: Shift the LED for the maximum dis-
play value to position 8, 7, 6 or 5. In the case of maximum flow all
LEDs from 0 up to this LED are lit. The LEDs above the range signal
excess flow. If the switch point is above this range, the unit switches
in the case of excess flow.
