MultiSmart Installation & Operation Manual
16 Station Optimization
The MultiSmart pump station manager includes a wide range of configurable parameters for optimizing a
pump station, such as:
Parameter Description
Pump Reversal
Many wastewater utilities reverse pumps periodically to help avoid blockages. They also
reverse pumps on certain faults (where those faults are believed to be mainly caused by
blockages
). Pump reversal can easily be configured to operate on a set numbers of
cycles and/or under certain fault conditions.
CAUTION: Check with your pump manufacturer before using this feature.
Odor Reduction via
maximum off time
Sewer stations with both high and low-use periods often generate odours. During the low
use period (e.g. a weekend),
the station may take a number of days to reach the
activation level for the pump. This allows the station to become septic. This feature
allows a maximum off time to be
applied so the station is completely emptied in order to
reduce septic odours occurring.
Max Run Time
Maximum run time is used to prevent any pump from running too long. It does this by
cycling the pumps when a maximum run time is reached. A fault notific
ation can be
triggered when this happens, if desired.
Max Pumps to Run
This feature is used to limit the total number of pumps allowed to run at any one time.
This is usually done to prevent damage to equipment from either electric or hydraulic
overload.
Minimize Fat Build-up
This feature sets a random activation delay for a pump in order to stop fat building up at
the activation level in the well.
Well Clean Out
This feature allows the pumps to be run past the normal deactivation point for a set time
o
r to a set level in order to completely empty the well. This can be set to occur at regular
periods.
Minimize Excessive Starts
This feature helps keep the maximum starts per hour of a pump below the level
recommended by the manufacturer. It works by autom
atically adjusting the activation
level upwards to minimise starts whenever the settings are exceeded. There is an over-
ride level to ensure that the activation point does not move too high.
High Inflow
Enables detection of a high inflow rate and if present, a fault is displayed and/or the lead
pump is pulsed started.
Well Washer A variety of parameters can be set to optimize use of a well-washer to clean the well.
Well Mixer Allows control over a well mixer. Two modes, Every Pump Cycle and Every x Hours.
Blocked Pump Detection
If the lag (standby) pump keeps cycling on and off, while the lead (duty) pump stays on,
it indicates a blocked pump.
Max Pump Starts Per Hour
Individual pumps can be limited to a maximum number of starts per hour if required.
There is an over-ride level to ensure that an overflow is not risked.
Table 19 – Station Optimization Parameters
The most common settings are found in the main station optimization screen. The Pump Station Manager
functionality has a whole range of advanced pump station parameters and can support multiple wells,
multiple groups of pumps and multiple profiles.
The Advanced button gives access to these complete settings which are listed under Pump Control in the
Advanced screen. Some parameters are found under the heading “Wells”, some under “Groups” etc., even
when there is only one well or one group.
