Alerts and Warnings
The IntelliFlo
®
VS+SVRS Pump 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 pump will not start if the
impeller is rotating. The alerts and warnings are:
•
Power out failure:
The incoming supply voltage is less than 170 VAC. The drive faults to protect
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.
•
Priming error:
If the pump is not defined as primed within the “Max Priming Time” it will
stop and 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 pump
cannot prime within five attempts it will generate a permanent alarm that must be manually reset.
•
Overheat alert:
If the drive temperature gets above 130 degrees, the pump will slowly reduce
speed until the over temperature condition clears.
•
Anti-freezing:
When active, the motor will run at the preset RPM until the drive temperature
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
®
Control System'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:
Detects a blocked suction line. This alarm resets automatically after two (2)
minutes and the pump restarts.
•
Over current:
Indicated that the drive is overloaded or the motor has an electrical problem. The
drive will restart 20 seconds after the over current condition clears.
•
Over voltage:
Indicates excessive supply voltage or an external water source is causing the pump
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:
When the pump is in PRIMING MODE, the SVRS feature is DISABLED.
