I I 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.

maximum flow
The output signal indicates the maximum flow and excess flow. The
output current for maximum flow/excess flow depends on the
position to which the LED for the maximum display value has been
shifted.
