8.2.1 Anti-seizing
Anti-seizing parameters are set in this display.
The anti-seizing function prevents a pump from choking/seizing up
as a result of limestone buildup or other deposits. Anti-seizing is
used in pits that have had no inlet flow for a long period, or if it is
not possible to use alternating operation.
The anti-seizing function ensures that the pumps start as often as it
is set in "Anti-seizing, start interval". The pumps operate for the
number of seconds indicated by the user.

8.2.2 Daily emptying
Daily-emptying parameters are set in this display. "Daily start time"
is the start time for daily emptying.
The daily-emptying function is used when there has been no inlet
flow into the pumping station for a long period. Daily emptying
prevents the water from smelling and prevents sediment building up
on the inside of the pit.
If the pit is very large, daily emptying can be set to take place at
night as off-peak power often costs less.

8.2.3 Foam draining
Foam-draining parameters are set in this display.
The foam-draining function can only be used if the pumps
are suitable for dry running.
The foam-draining function ensures that the water is drained right
down to the pump inlet level. The foam is then drained to stop it
from sticking onto the pit walls.
Foam draining is activated with the next pump start once the "Start
interval" period has ended.
Enable/disable foam draining.
Foam draining
•
Fixed interval (start interval for foam draining)
•
Fixed daily time (daily start time for foam draining)
•
Level (level at which the pump stops)
•
Stop delay (time delay before the pump stops)
•
Start interval (start interval for foam draining)
•
Daily start time (time for fixed daily foam draining)
Foam drainage is activated at the first pump cycle after the "Start
interval" or "Daily start time" has been reached.

8.2.4 Mixer configuration
The mixer parameters are set in this display.
The mixer stirs the liquid in the pit to prevent sediment from settling
on the pit sides or bottom.
If the function "Pump groups" is enabled, the start and stop levels of
the mixer must be between the start and stop levels of pump group
1.
Mixer enabled
Tick the box in this field if a mixer is installed in the pit.
Start level 1↔Start level, mixer
The mixer starts at "Start level 1" minus a configurable distance.
Example:
When "Start level 1" is 1.75 m and "Start level, mixer" is
0.05 m, the mixer starts at 1.70 m.
