pause time (window 22). The parameters can be adjusted to achieve desired
magnitudes of pause times, start level and number of starts per hour. See Fig.
11, page 23, and 14, page 32.
The level setting in window 21 is set for shorter or longer pumping and pause
cycles. Higher values increase the calculated pause time and the amount of accu-
mulated water.
The level setting is best adjusted after a few pumping cycles in order to adjust
the pause time, and hence the start level in the pit. See schematic pump cycle
example in Fig. 11 and 14.
Maximum pause time for the pump is set in window 22. The calculated pause
time will be limited to this value. In some applications the inflow may increase
rapidly during a pause. To prevent overflow in these situations the maximum
pause time can be set in accordance with the circumstances.
