VSF Variable Speed and Flow 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: 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: 20 seconds
Priming delay can be set from 1 second to 10 minutes.
When a pump ramps to full priming speed in an attempt to establish a prime, priming
delay allows the pump to operate at that speed for an additional set period of time prior
to continuing on to the requested or scheduled program.
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: 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: Enabled
This feature allows the pump to recognize unanticipated low-flow or no-flow situations
while running a program.
For example, the pump will pause for one (1) minute after detecting that it has lost
its prime unexpectedly. After this pause the pump will attempt to prime, and if prime
is successful it will continue programmed operation. If priming is not successful the
pump will continue attempting to prime, per normal priming operation, until a prime is
achieved or priming error occurs and is displayed.
