The volume in the pit at
pump start after pause
time is equal to pump
capacity (litres/min) mul-
tiplied by level setting
(window 21).
Examples 1 and 2:
Pump capacity
600 (litres/min) x 1
(Value in window 21) =
600 litres in the pit when
the pump starts to pump.
Example 3:
Pump capacity 600
(litres/min) x 2.3 (value in
window 21) = 1380 litres
in the pit when the pump
starts to pump.
