Possible Causes
Excessive heating in Pentair Pentek
Intellidrive ® Constant Pressure Pump
Controller
Leak detected
Application calls for long run times
Internal voltages are out of range
Internal hardware failure
The external device detected fault condition
and closed the I1 or I2 input
Motor not wired correctly to Intellidrive
Thermal protector open in 1-phase motor
Missing motor phase
Possible Causes
Ungrounded Intellidrive, with ground detection
parameter disabled (will operate for 72 hours
and then fault).
Debris in pump stopping motor from turning
(locked rotor).
Pressure rising above Over Pressure setting.
Plugged vents, fan not working, high ambient
temp, direct sunlight, etc. Also high power
draw.
Internal Intellidrive error.
Internal Intellidrive error.
Internal Intellidrive error.
Low voltage on DC Bus caused by heavy
loading, low incoming voltage, or unbalanced
output current.
Solution
Check ambient temperature is not above 50°C (122°F).
Check for inoperable or unobstructed fan.
Check vents are not obstructed.
Check for leaks in pipe system.
Extend Excessive Runtime Hours limitation.
Disable Excessive Runtime Fault.
Intellidrive will auto reset and attempt to clear fault. Fault Reset can be
pressed to clear fault as well. Then try to operate pump. If fault continues
Intellidrive may need replacement.
Fault Reset can be pressed to clear fault. Then try to operate pump. If
fault continues Intellidrive may need replacement.
Check external device.
2-Wire motor should be connected to Y & B
Wait 20 minutes then restart pump.
Check all motor connections at the Intellidrive.
Solution
Verify ground wire is connected on both incoming voltage side and motor
side of Intellidrive.
With the power disconnected, use an ohmmeter to verify which pipe the
Intellidrive' s transducer is connected to. Also verify that the input ground
wire is at the same potential, e.g., has approximately the same ohm
reading.
Verify the input ground is connected all the way back to electrical panel.
Intellidrive tries to free debris in pump by reversing or pulsing motor.
Intellidrive stops and waits 1 minute, then checks that pressure is below
the Overpressure Setting pressure. Below it restarts, if not checks again in
another minute. Can increase over-pressure value.
Improve ventilation, verify fan is working, provide shade, etc. Verify proper
system sizing.
Power cycle the Intellidrive. If Fault continues Intellidrive may need
replacement.
Power cycle the Intellidrive. Reset Intellidrive to factory defaults. If Fault
continues, Intellidrive may need replacement
Power cycle the Intellidrive.
Check wiring for shorts, imbalance, and voltage. Verify proper grounding.
