Priming

The default setting for Priming is ENABLED. Enabling this feature allows the pump to use its "Flow
Technology" to make sure the pump is primed when it starts. This feature will not override the "Max
Speed" setting. The priming feature ramps the pump to 1800 RPM and pauses for three (3) seconds.
If there is suffi cient water fl ow in the pump basket, the pump will go out of priming mode and run its
commanded speed. If the fl ow in the pump basket is not suffi cient, the pump will ramp to the "Max
Speed" setting and stay there for the priming delay time, which is defaulted at 20 seconds. If there is
suffi cient water fl ow in the pump basket at this time, it will go out of priming mode and ramp to the
commanded speed. If there is still insuffi cient fl ow in the pump basket, the pump will try to prime at
the "Maximum Speed" for the amount of time set up in the "Maximum Priming Time" menu.
Maximum Priming Time: The Maximum Priming Time can be set from 1 minute to 30 minutes. The
default setting is 11 minutes. This is the maximum amount of time the pump will try to prime before
giving an error. However, if the pump does not see a suffi cient amount of water in the pump basket, this
can cause the pump to report a Dry Priming Alarm within seconds of the beginning of the priming cycle.
Priming Dry Alarm: An insuffi cient amount of water in the basket during priming will cause the
pump to report a Priming Dry Alarm. The basket should be fi lled with water and the pump restarted
when this alarm occurs.
Note: When a Priming Dry Alarm takes place it will try to restart after 10 minutes.
Primed Sensitivity: The primed sensitivity can be set from 1% to 100%. The factory default setting is
1%, meaning the pump is at its most sensitive setting in regards to determining if the pump has attained
a prime or not. Increasing this number will decrease the amount of fl ow needed for the pump to sense
that it is primed. Increasing this number too high could cause the pump to think it has attained a prime
and evacuated the air from the system when it has not. Increase the Primed Sensitivity number if the
pump has trouble coming out of the priming mode and the pump basket is full of water and fl owing.
Priming Delay: The priming delay can be set from 1 second to 10 minutes. The default setting is 20
seconds. This means the pump will ramp to 1800 RPM and remain there for three (3) seconds, which
it will always do in the hard Priming Mode. If there is suffi cient fl ow in the pump basket, the pump
will then go out of priming mode and ramp to its commanded speed. If there is insuffi cient water fl ow
in the pump basket, the pump will ramp to the Max Speed Setting and stay there for the default time
of 20 seconds. It may be necessary to increase the prime delay to allow the system to stabilize before
the pump goes into running mode. If the pump errors out immediately after priming, then increasing
the Priming Delay time may correct the issue.
When the pump is connected to an automation system and the "Maximum Prime Time" feature is
enabled, it will remain active.
