CAUTION:
Before installing this product, read and follow all warning notices and
instructions on page iii - vi.
Alerts and Warnings
The IntelliFlo VS displays all alarms and warnings on the control panel display. When an alarm or warning
condition exists, the corresponding LED will be lit on the display. All control panel buttons are disabled until
the alarm or warning is acknowledged with the Enter button. Press the Reset button to clear the alarm
once the fault condition has been resolved. Note: The IntelliFlo VS pump will not start if the impeller is
rotating. The alerts and warnings are:
•
Power out failure:
itself from over current. The drive contains capacitors that keep it powered up long enough to save
the current run parameters. If power is restored during this process, approximately 20 seconds, the
drive will not restart until completed.
•
If the pump is not defined as primed within the "Max Priming Time" it will stop and
Priming error:
generate a "Priming Alarm" for 10 minutes, then attempt to prime again. The "Max Priming Time" is
set by the user on the priming menu as discussed on page 12. If the IntelliFlo VS cannot prime
within five attempts it will generate a permanent alarm that must be manually reset.
•
Overheat alert:
reduce speed until the over temperature condition clears.
•
When active, the motor will run at the preset RPM until the drive temperature
Anti-freezing:
increases above the minimum. The pump's internal antifreeze protection is disabled when connected
to an automation system. Freeze protection is provided by selecting YES at the ON WITH FREEZE
portion of the IntelliTouch's appropriate circuit function menu. To re-enable the pump's internal
antifreeze protection, the power to the drive must be cycled off then back on.
•
Blocked system:
minutes and the pump restarts.
•
Indicated that the drive is overloaded or the motor has an electrical problem. The
Over current:
drive will restart 20 seconds after the over current condition clears.
•
Indicates excessive supply voltage or an external water source is causing the pump
Over voltage:
and motor to rotate thereby generating an excessive voltage on the drives internal DC buss. The
drive will restart 20 seconds after the over voltage condition clears.
Suction Blockage
When something blocks the suction or the pump fully it will shut off immediately (within 1 second). It will
also shut off after a few seconds of dead heading with the same alert. The unit will come back on in two (2)
minutes and ramp up slowly. This function should be tested with all new installations. When something fully
blocks the suction of the pump it will shut off immediately. It will also shut off after a few seconds of dead
heading with the same alert. The unit will reset after two (2) minutes and ramp up to speed slowly. This
function should be tested on all new installations. The operation can be checked in one of two ways. The
first method requires the system to have a fast closing ball, butterfly of sliding valve in the suction line. This
valve should be quickly closed in less than one (1) second. The second test method requires the use of a
test mat to quickly cover the suction outlet to simulate an entrapment event.
SVRS Blockage:
WARNING ! When the pump is in PRIMING MODE, the SVRS feature is DISABLED.
The incoming supply voltage is less than 170 VAC. The drive faults to protect
If the drive temperature gets above 130 degrees, the IntelliFlo VS will slowly
