OPERATING THE PUMP 16/20
PRIMING FEATURES
Default: ENABLED
Allows IntelliFlo® VSD2 Variable Speed Pump to automatically
detect if pump if is primed for startup. The pump will speed up to
1800 RPM and pause for three (3) seconds - if there is enough water
in the basket, the pump will go out of priming mode and run the
commanded speed.
Default: 3450 RPM
The priming speed can be set between 2400 RPM and 3450 RPM.
If the pump is on an equipment pad that is close to the water level,
it will not need to run at 3450 RPM to successfully prime. The
setting can be lowered to prevent running at a higher speed than
necessary. Day to day factors (i.e. local ambient pressure, water/air
temperatures, amount of water retained from last system run) can
effect priming performance. Because of the frequently changing
nature of these factors the priming speed should be set high enough
to accommodate environmental and mechanical changes to ensure
that the pump can successfully prime. Finding the most effective
and efficient speed for your specific needs may take careful testing
and evaluation of priming performance.
Default: 11 minutes
The maximum priming time can be set from 1 - 30 minutes. This
setting is the amount of time the pump will try to prime before it
gives a priming error. If this occurs, fill the pump basket with water
and restart the pump.
Default: 5
Priming range can be set from 1-10. The smaller the range, the
more water the pump has to be moving to detect that it is primed.
At larger ranges, the pump will detect that it is fully primed while
moving less water. If the range is set too high, then the pump
may exit Priming mode before it has fully primed. The range will
automatically adjust with the priming set speed because the flow
rates of the pump will be lower at lower speeds.
Default: 20 seconds
Priming delay can be set from 1 second to 10 minutes. If the pump
does not have enough water after the automatic priming mode, the
pump will increase to the Priming Speed (under “Pump Settings”
on page 8) and run for 20 seconds (or for the time set).
You may need to increase the priming delay to allow the system to
stabilize before the pump starts running speeds. If pump continues
to show a priming error, increasing the priming delay time might
correct this issue.
