Manual adjustment to maximum flow (HI-Teach) /
monitoring excess flow
The unit detects the current flow and sets this value as the maximum
value for the LED display (LED 9).
In addition the
position of the display window
within the detec-
tion range can be defined: Shift the LED for the maximum display
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.
